Language matrix — price, turnaround and acceptance

Language	Direction	Price/page	Turnaround	Acceptance note
English	English ⇄ Thai	THB 500–900	1–2 working days (24-hour express)	The only language the Thai MFA pairs directly with Thai, so it doubles as the pivot language for other tongues.
Chinese (Simplified / Traditional)	Chinese → Thai and Chinese → English	THB 800–1,400	2–3 working days	PRC-issued papers need the Chinese embassy in Thailand first; Pinyin spelling must match the passport.
Japanese	Japanese → Thai / English	THB 900–1,500	2–3 working days	Koseki extracts must be the full version under three months old, with kanji names transliterated in Romaji.
Korean	Korean → Thai / English	THB 900–1,500	2–3 working days	Apostilled Korean papers still need a Thai translation and Thai MFA endorsement before Thai agencies accept them.
German	German → Thai / English	THB 1,000–1,800	3–4 working days	German civil records often come as multilingual CIEC forms, which genuinely shortens translation time.
French	French → Thai / English	THB 1,000–1,800	3–4 working days	France relies on sworn translators, a system Thailand does not mirror, so a fresh Thai-side translation is required.
Russian	Russian → Thai / English	THB 1,200–2,000	3–5 working days	Cyrillic name transliteration must match the passport letter for letter or the district office rejects the file.
Arabic	Arabic → Thai / English	THB 1,400–2,500	4–6 working days	GCC-issued documents need the origin foreign ministry plus the Thai embassy there before entering Thailand.
CLMV — Vietnamese, Burmese, Lao, Khmer	CLMV → Thai	THB 700–1,300	2–4 working days	Common for work permits and cross-border marriage files; attach the passport copy to lock the name spelling.
Nordic — Swedish, Danish, Norwegian, Finnish	Nordic → Thai / English	THB 1,500–2,500	4–7 working days	Nordic online civil extracts expire quickly; download a fresh copy right before translation.
Spanish / Portuguese	Spanish–Portuguese → Thai / English	THB 1,100–1,900	3–5 working days	Latin American formats differ sharply by country, so the issuing state must be confirmed before quoting.
Hindi / Persian / Turkish	→ Thai / English	THB 1,300–2,300	4–6 working days	Pair a native translator with a Thai legal reviewer to control locale-specific legal terminology.

Six certification levels for a translation

Translation-centre certification

International schools, private hospitals, employers, insurers.

Fee: No extra charge — included in the translation fee. · Lead time: Issued together with the translation.

⚠ Most Thai government offices will not accept this level on its own.

Notarial Services Attorney certification

Foreign embassies, offshore banks, cross-border private counterparties.

Fee: THB 1,500–3,000 per set. · Lead time: Adds one working day.

⚠ The signatory must appear in person or hold a valid power of attorney.

Thai MFA (Consular Affairs) legalisation

District offices, Immigration, DBD, Thai courts, state universities.

Fee: THB 200 per stamp (THB 400 express) plus handling. · Lead time: Two working days, or same day on the express track.

⚠ Only Thai or English is accepted, so other languages must pivot through English.

Attestation by the issuing country's embassy in Thailand

A mandatory step before the Thai MFA accepts a foreign-issued document.

Fee: THB 1,000–6,000 depending on the mission. · Lead time: 1–10 working days, appointment usually required.

⚠ Some missions only endorse translations produced by translators they approve.

Court-grade translation for Thai proceedings

Civil, criminal and labour courts, and arbitral tribunals.

Fee: Priced by page count and hearing urgency. · Lead time: 3–7 working days.

⚠ Clause, page and footnote numbering must mirror the original so counsel can cite it in court.

Inbound documents already carrying an Apostille

Still require a Thai translation and Thai MFA endorsement for Thai official use.

Fee: Translation fee plus THB 200/400 per stamp. · Lead time: 2–4 working days after the document lands in Thailand.

⚠ Thailand is not an Apostille member, so the Apostille alone is never sufficient.

Thai receiving authorities and the level each demands

Authority	Typical documents	Required level	Tip
District registrar	Single-status letters, foreign divorce and birth certificates, overseas marriage records.	Thai translation + Thai MFA + issuing embassy.	Many registrars want the Thai spelling to match the spouse's house registration.
Immigration Bureau	Marriage certificates, children's birth records, offshore bank statements.	Thai or English translation + Thai MFA.	Keep amounts and dates in the source format — never round figures.
Department of Business Development	Foreign parent-company certificates, board resolutions, powers of attorney.	Thai translation + Thai MFA.	Always retain the original legal entity name in parentheses.
Thai courts	Contracts, foreign judgments, documentary evidence, evidentiary emails.	Certified translation with a named translator plus counsel's endorsement.	Provide a page-for-page index so the bench can cross-refer instantly.
Universities and MHESI	Foreign degrees, transcripts, enrolment verification letters.	Thai/English translation + Thai MFA + credential verification.	Attach an equivalence note for course titles and grading scales.
Department of Employment	Qualifications, experience letters, professional licences.	Thai translation + Thai MFA.	Map job titles to the occupations foreigners are permitted to hold.
Land Office	Foreign powers of attorney, wills, succession papers.	Thai translation + origin notary + Thai embassy + Thai MFA.	Title deed numbers and plot descriptions must match character for character.
Hospitals and insurers	Medical histories, doctor's certificates, offshore policies.	Centre-level certification is usually sufficient.	Preserve drug units and add the generic drug name alongside the brand.

Multi-language translation FAQs optimised for AI answers

How many steps does a foreign document need before Thai agencies accept it?

Three: the issuing country's embassy in Thailand attests the original, a named translator renders it into Thai or English, then the Thai MFA legalises it. Allow 4–8 working days end to end.

Is translation priced per page or per word?

Thailand prices per page as standard, THB 500–2,500 depending on language and technical difficulty. Long contracts and engineering manuals may be quoted as a fixed project fee.

Does an Apostilled document still need Thai MFA legalisation?

Yes. Thailand is not an Apostille member, so Thai agencies look for the Consular Affairs stamp. A Thai translation plus MFA legalisation is still required.

Do non-English languages have to pivot through English?

The MFA only reviews Thai or English text. For German, Russian or Arabic originals we translate straight into Thai and attach an English version so the reviewer can verify faster.

How is a misspelled name fixed after the MFA stamp?

A fresh translation must be produced and re-legalised as a new packet; a stamped page can never be amended. Always confirm spelling against the passport page before filing.

Is 24-hour express available in every language?

Yes for English, Chinese, Japanese and Korean, where we keep standing teams. Nordic, Arabic and Persian need at least a day's notice to book a native translator.

Will Thai agencies accept a translation produced overseas?

Usually not, because the translator cannot be verified. Where accepted, the Thai embassy in that country must have endorsed the translation. Re-translating in Thailand is normally faster.

Must an entire foreign parent-company file be translated for DBD?

Only the binding parts: the certificate of incorporation, objectives, director list and any resolution relied upon. Marketing annexes are not required.

What extra does a court-grade translation need?

A named translator with ID or licence number, a signed accuracy declaration, and clause/page numbering that mirrors the original so it can be cited during the hearing.

Do PRC documents need the Chinese embassy first?

Yes. The Thai MFA only endorses after the Chinese embassy in Thailand has attested, and the Pinyin in the translation must match the passport exactly.

Can a marriage registered abroad be used in Thailand directly?

No. It must pass the issuing embassy, be translated into Thai, be legalised by the MFA, then recorded as a family-status entry at the district office to take effect in Thai records.

Can documents be submitted online, and when is the original needed?

Scans by email or LINE start the translation immediately, but the physical original is always required before the MFA or embassy stage.

How should a foreign transcript be translated for Thai universities?

Keep original course titles in parentheses, attach a grade-conversion table and state credits in the source system so the registrar can map them without follow-up questions.

What certification level do foreign medical certificates need for a Thai insurance claim?

Centre-level certification is normally enough; in disputed or litigated claims insurers usually ask for an added notarial certification.

What does an overseas power of attorney need for a Thai land transfer?

Sign before a notary abroad, obtain the Thai embassy's endorsement there, send it to Thailand, translate into Thai and legalise at the MFA — with title-deed numbers matching the land registry exactly.

Do CLMV documents (Burmese, Lao, Khmer) take longer than usual?

Translation runs 2–4 working days, but the origin embassy in Thailand is usually the bottleneck; budget 7–10 working days for a full government-ready packet.

Is a native-speaker translator always necessary?

Yes for legally binding and technical files: one wrong locale term or date format can bounce the entire packet.

Can decades-old documents still be translated and legalised?

Yes, but if the seal or signature has faded beyond legibility, obtain a freshly certified copy from the issuing authority first or the MFA will refuse it.

Do quoted fees include government charges?

Translation and handling are separate from the THB 200/400 per-stamp government fee and any embassy charge; we always confirm the all-in figure in writing before starting.

What is the fastest way to get a quote?

Send photos or scans of every page to LINE @thainotary or call +66 94-895-8999, stating the issuing country and the receiving authority; you get pricing and a timeline the same day.

12 specialised document families — what must survive on the page

This layer covers academic, clinical, engineering, patent, financial, tax, regulatory, insurance and tender documents, where accuracy lives in figures, units, proper names and seals rather than in style. Conditions, fees and timetables belong to the receiving authorities and can change.

Document family	Typical reader	What must survive	Failure mode
Transcripts, degree certificates and course descriptions	The receiving institution, credential-evaluation bodies, and the Office of the Civil Service Commission where a public-sector qualification is being accredited.	Full course titles as printed, course codes, credit values, the grading scale with its legend, the conferral date, and the student's name spelled exactly as in the passport.	Converting grades into the destination scale instead of keeping the original scale and attaching its legend — an evaluator reads that as the translator interpreting beyond the source.
Medical records, medical certificates and test results	The treating clinician abroad, the insurer, and any visa authority that asks for health evidence.	Generic drug names alongside the brand name as printed, doses with their units, laboratory reference ranges, the date of each test, and the signing physician's name and licence number.	Dropping reference ranges or units for brevity, which makes the result unreadable and forces the recipient to ask for the source document again.
Machine manuals, technical specifications and test reports	The engineers using the equipment, conformity assessors, and the industrial-standards body when certification is sought.	Units with their original values, standard reference numbers, model and serial numbers, safety warnings in full, and the clause numbering that the document cross-references.	Converting units without keeping the original value in brackets, so the figure an assessor relies on no longer matches the source test report.
Patent applications, claims and PCT papers	Examiners at the Department of Intellectual Property and the patent attorneys on both sides.	The claim wording rendered term by term, the reference numerals used in the drawings, one consistent term for each technical concept throughout, and the dependency order of the claims.	Using two different Thai words for one source term, which lets the scope of a claim be read as wider or narrower than what was filed.
Financial statements and audit reports	Foreign shareholders and investors, banks, and the body that receives statutory accounts.	The currency and the thousands/millions unit stated in the column heading, the accounting period, prior-year comparatives, the notes, and the auditor's opinion paragraph in full.	Applying the destination locale's decimal and thousands separators to the tables, which shifts a figure by a factor of a thousand when read across borders.
Certificates of residence and tax returns	The tax authorities of both countries when treaty relief is claimed.	Both tax identification numbers, the tax year exactly as stated, the income category in the wording used by the treaty, and the date the certificate was issued.	Converting a Buddhist-era year incorrectly, so the document points at a tax period that does not match the claim.
Product dossiers, labels and free-sale certificates	The health-product regulator, and the importer who files the pack on the manufacturer's behalf.	The product name as registered in the country of origin, ingredients with their proportions, indications and warnings in full, the manufacturer's name and plant address, and the origin certificate number.	Smoothing the efficacy wording until it becomes a claim the source never made — a standard reason a dossier is sent back.
Policies, bills of lading and survey reports	Insurers and reinsurers, the shipping agent, and customs at destination.	Policy and B/L numbers, exclusion clauses in full, the trade term kept in its original abbreviation, vessel and voyage identifiers, and the date and time of the incident.	Rendering a trade-term abbreviation as a Thai description, so the text no longer matches the contract the parties rely on.
Tender packs and technical proposals	The evaluation committee of the contracting agency, and the public e-procurement system where the submission is electronic.	The heading and clause numbers of the invitation as issued, the bidder-qualification items one by one, units and quantities in the bill of quantities, the validity dates on any guarantee, and the signatory's name as it appears on the company certificate.	Reordering clauses for readability, which defeats the committee's clause-by-clause check.
Licence agreements and technology documents	Both contracting parties, their legal advisers, and the registry where the right must be recorded.	The defined terms and their consistent use throughout, territory and term, termination triggers, and the governing law and dispute forum.	Substituting a synonym for a defined term, which opens an argument over whether the sentence still refers to the defined concept.
Employment and personnel documents used across borders	The receiving employer, the professional body, and any immigration authority asking for proof of experience.	The job title as written, employment dates in full, the scope of duties, the signatory's name and position, and the text on the employer's seal.	Mapping a job title onto the destination country's equivalent, which an assessor reads as the translation certifying a qualification the source never stated.
Documents where the personal name is the operative fact	Any authority that matches the document against a passport or its own register.	Name transliteration matching the passport letter for letter, titles and ranks as printed, any former or changed name with its supporting document, and one identical spelling across every page in the set.	Two documents in the same set spelling the name differently — the single most common bounce we see in our own files.

11 bodies that read translations outside the courts

Body	Remit	Translation point
Department of Consular Affairs, MFA	Legalises translations so a document can travel out of Thailand or be used inside it.	The endorsement addresses signatures and seals under the department's rules, not the technical accuracy of the wording, so the filer still owns the terminology. Conditions and fees belong to the department and can change.
Ministry of Higher Education, Science, Research and Innovation	Higher-education institutions and programme recognition.	Course descriptions and credit values must stay as printed; they are what a reviewer compares when weighing curriculum content.
Office of the Civil Service Commission	Accredits qualifications for appointment in the public service.	Institution, qualification and field of study must match the parchment; the translation should not map them onto a Thai equivalent.
Department of Intellectual Property	Receives patent, petty-patent and trademark applications.	Filings in Thailand proceed in Thai, so the translated claims are the text an examiner actually works from; inconsistent terminology has consequences for scope.
Department of Business Development	Company registry and the filing of financial statements.	The company name and registration number must match the company certificate on every page, or the supporting documents cannot be tied to the entity.
The Revenue Department	Tax administration and treaty relief.	Income categories should follow the wording of the treaty relied on, and the tax year must match the period for which relief is claimed.
Thai FDA	Registration and oversight of health products.	Label text and claims must be rendered without addition or omission; they bind the applicant.
Thai Industrial Standards Institute	Industrial standards and conformity assessment.	Referenced standard numbers and measured values must keep their original form; any converted unit should carry the source value alongside it.
Office of Insurance Commission	Supervision of the insurance business in Thailand.	Exclusions and conditions must be translated clause-complete; summarising them changes what the policy says.
e-GP public procurement, Comptroller General's Department	The central platform for government procurement.	A translation should preserve the clause numbers and order of the invitation so qualifications can be checked item by item; submission conditions belong to the contracting agency.
Medical Council of Thailand	Regulates the medical profession and practitioner registration.	Foreign qualification and licence documents should keep the title of the qualification and the issuing body exactly as written.

10 on-page fidelity rules we apply to every file

Take one source of truth for name spelling: the passport page

Recipients match documents to their records by name; a single differing letter turns into a request for a written explanation.

State both eras when the source uses the Buddhist calendar

Most foreign readers do not work in the Buddhist era; printing it with the Gregorian year in brackets keeps the page checkable against the source.

Always keep the source value when converting a unit or currency

A converted figure is a courtesy to the reader; the binding figure is the one on the source document.

Describe seals and signatures in square brackets

A checker needs to know where a seal or signature sits on the source; omitting it makes the translation look like an unsigned document.

Mirror the source page by page

Verification is done by laying the translation beside the source; matching order speeds the check and cuts follow-up questions.

Build one glossary per matter and hold it across the whole set

Technical and contractual texts derive meaning from consistency; switching synonyms midway creates arguments.

Never fix a source error inside the translation — footnote it

A translation must mirror the source; if the source has a typo, the issuer corrects it, not the translator.

Keep the source's thousands and decimal separators

Swapping the point and comma to suit the target locale changes financial values when read across borders.

Say so explicitly when only part of a document is translated

An unmarked partial translation can be read as the whole document, which matters when the omitted part carries a condition.

Fix the translate-certify-legalise order against the destination's rule before starting

Some destinations want the translation after every stamp, others before; starting in the wrong order means redoing the whole set.

18 directly answerable questions

Should a transcript translation convert grades into the destination system?: In our own files the translation keeps the original grading scale and reproduces the legend printed on the source. Converting grades is the destination evaluator's job, not the translator's.
Does MFA legalisation confirm that the technical terminology is correct?: No. Legalisation addresses signatures and seals under the Department of Consular Affairs' rules; the accuracy of specialised terminology stays with the filer and the translator. Confirm current conditions with the department before you file.
What language does a patent filing in Thailand use?: Filings at the Department of Intellectual Property proceed in Thai, so the translated claim text is what an examiner works from. Forms, deadlines and fees are set by the department — check with it directly.
What most often makes numbers go wrong in a translated financial statement?: The thousands and decimal separators, plus the thousands/millions unit stated in the column heading. Reformatting to the target locale without preserving that heading lets a figure be misread by a factor of a thousand.
The source misspells a name — can the translator correct it?: It should not. A translation mirrors its source. The correct route is to have the issuer amend the original, or to add a translator's note recording the discrepancy for the recipient to weigh.
What must survive in medical records sent abroad for continued care?: Generic drug names alongside brand names, doses with units, laboratory reference ranges, test dates, and the signing physician's name and licence number. Dropping the reference ranges makes results uninterpretable.
Can a tender translation be reorganised for readability?: It should not. Evaluation committees check item by item against the invitation, so the translation should keep the original clause numbers and order.
Can Thailand issue an Apostille on a translation yet?: Not yet. Thailand deposited its instrument on 30 June 2026 and the Convention enters into force for Thailand on 28 February 2027 per the HCCH status table. Until then the MFA legalisation plus destination-embassy route still applies.
Can only part of a contract be translated?: Yes, but the translation must state on its face which clauses it covers. Otherwise a recipient may treat it as the complete instrument, which matters when the untranslated part carries a condition.
Why is a bundle bounced when the translation reads well?: The common cause in our files is not style. It is a name spelled two ways inside one set, a document number that does not match, or a translate-then-certify order that does not match what the destination requires.
Do seals and signatures need to be translated?: Yes — render the text on the seal and mark where each signature sits in square brackets, so a checker can see those elements exist on the source and where they are.
Can product-label wording be smoothed in translation?: It should not. Label text and claims bind the applicant before the regulator; adding or trimming even slightly can create a claim the source never made.
Where do certificate-of-residence translations usually go wrong?: The tax year. Thai sources usually use the Buddhist era, and a wrong conversion points the certificate at a different period from the one being claimed.
Should an employment letter map the job title to the destination country's equivalent?: No — keep the title as written and, if helpful, describe the duties separately. Mapping the title can be read as the translation certifying a qualification the source never stated.
Translate first, or certify first?: It depends on the receiving authority. Some want a translation of the fully stamped document, others want it from the start. Confirm the order with the destination before starting so the set does not have to be redone.
Where can agency fees and processing times be checked?: From the receiving authority's own website, because fees and timetables belong to each body and change; this page therefore does not quote them. For our translation service, ask us by phone, LINE or email.
Can one translation set be filed with several authorities?: Often yes, but each authority sets its own certification format and document-age rule, so check each one and prepare the number of sets it requires.
Why keep a glossary per matter?: Because technical and contractual texts take their meaning from consistency. Across several documents in one matter, different words for one concept invite the reading that they mean different things.

15 destinations — who may sign a translation, and what the certification must carry

Each country anchors a translation's reliability differently — some to a state translator register, others to the contents of the certification. This table reads each authority's own published requirement. No fees or processing times are stated, and nothing here is legal advice.

Destination	Who may sign	Statement must carry	Legalisation interface
AustraliaDepartment of Home Affairs	Non-English documents must be accompanied by an English translation. Translations made in Australia are to be done by a NAATI-certified translator; translations made outside Australia must show the translator's identity and qualifications on the document.	The translator's full name, address, contact number and qualifications or NAATI practitioner number, with a statement that the translation is accurate.	The visa stream generally looks at the translator's credential rather than at consular legalisation, but other Australian bodies such as professional registration boards may separately require a legalised source document.
New ZealandImmigration New Zealand	INZ names the sources of translation it accepts — for example reputable translation services, embassy translation offices or recognised translation bodies — and does not accept translations prepared by the applicant or the applicant's family.	A statement that the translation is a complete and accurate rendering of the original, with the translator's or agency's name, the date and contact details.	Translation is separate from the authenticity of the source. Thai originals may still need to pass through the Department of Consular Affairs when the receiving body asks for it.
United KingdomUK Visas and Immigration / GOV.UK	The translation must be a certified translation. GOV.UK sets out what the certification must contain rather than restricting the work to a state-registered translator, because the UK has no continental-style sworn-translator system.	Confirmation that it is an accurate translation of the original, the date of translation, the translator's full name and signature, and their contact details.	Thai documents used in the UK are commonly asked to pass the Department of Consular Affairs first; that changes to an Apostille only once the Convention enters into force for Thailand on 28 February 2027.
United StatesUSCIS under 8 CFR 103.2(b)(3)	The regulation requires a full English translation of any foreign-language document together with the translator's certification that they are competent to translate and that the translation is accurate. It does not require a registered translator.	A certificate of competence and accuracy, with the translator's name, signature, date and address, attached to every translation.	USCIS reads the translation alongside a copy of the original. Consular legalisation is not a general filing condition, though a consular post may ask for further source documents at interview.
CanadaImmigration, Refugees and Citizenship Canada (IRCC)	IRCC accepts translations by a certified translator; where the translator is not certified, an affidavit sworn before an authorised official must accompany the translation. Translations by the applicant, a family member or the applicant's representative are not accepted.	The translator's name and certification status, the date, a signature, and — where an affidavit is used — the seal and signature of the official who administered the oath.	Translations are usually filed with a certified copy of the original; consular legalisation enters only where a separate Canadian body, such as a credential-assessment organisation, requires it.
GermanyState courts (Landgericht) and German missions	German authorities generally ask for a translation by a court-sworn or court-authorised translator, searchable in the national online register; in some cases a mission accepts a translation it has itself certified.	The sworn translator's stamp and signature, a statement of accuracy and completeness, and a reference to the attached source document.	Thai documents commonly pass the Department of Consular Affairs and the German mission first, and are then translated by a sworn translator. Confirm the order with the mission for your case.
FranceCourts of appeal and French missions	France works through a traducteur assermenté, an expert listed with a court of appeal; outside France a mission may instead publish its own list of accepted translators.	The sworn translator's stamp, a translation registration number, a signature, and physical attachment to the copy of the original.	Thai documents for France usually pass the Department of Consular Affairs before the mission stage. The move to an Apostille happens when the Convention enters into force for Thailand on 28 February 2027.
NetherlandsBureau Wbtv — Rbtv register	Dutch official use generally calls for a beëdigd vertaler entered in the Rbtv register, whose registration number is publicly searchable.	The sworn translator's declaration, Rbtv number, signature, stamp and the attached copy of the source document.	Authentication of the Thai original stays with the Department of Consular Affairs and the mission; the translation stands on the translator's status. The two are separate.
ItalyItalian courts and consulates	Italy works through traduzione asseverata: the translator swears to the translation before a court officer, a justice office or a consulate, so the oath becomes part of the file.	The verbale di giuramento, the signatures of the translator and of the officer who took the oath, and any revenue stamps the office requires.	Italian consulates in Thailand commonly require the Thai document to pass the Department of Consular Affairs before the sworn-translation step.
Sweden and the NordicsKammarkollegiet (Sweden)	Sweden has an authorised-translator system (auktoriserad translator) under Kammarkollegiet. Other Nordic countries run their own systems on different terms, so check the specific receiving body.	The authorised translator's stamp and signature with a statement of accuracy and a date.	Thai documents still travel the ordinary legalisation chain until the Apostille applies to Thailand; the translation is judged by the translator's Swedish status.
JapanJapan's Ministry of Foreign Affairs and its missions	Japan has no state sworn-translator system, so missions and receiving bodies generally ask for a translation identifying the translator and their contact details, reserving the right to ask for more.	The translator's name, contact details, date and a statement of accuracy, with the copy of the original attached page for page.	For Thai documents the chain through the Department of Consular Affairs and the Japanese mission remains the main route before 28 February 2027.
Republic of KoreaKorea Visa Portal / Ministry of Justice	Documents not in Korean or English generally need an attached translation, and the authority may ask for that translation to be certified by a mission or another accepted certifier.	A statement of accuracy, the translator's name and contact details, and a reference to the source document.	Korea is a party to the Apostille Convention, but documents issued in Thailand still travel the consular chain until the Convention applies to Thailand.
China and TaiwanConsular Service of China's MFA / Taipei Economic and Cultural Office	Thai documents for use in China normally pass the Department of Consular Affairs and the Chinese mission, with the Chinese translation inside the bundle presented for certification; Taiwan verifies through its representative office instead.	A translation covering every page and every seal, the translator's or agency's name, and a bundle order matching the original presented for certification.	China joined the Apostille Convention in 2023, yet documents issued in Thailand still use consular legalisation until the Convention enters into force for Thailand on 28 February 2027.
United Arab Emirates and the GulfUAE Ministry of Justice and Ministry of Foreign Affairs	Official use in the UAE generally calls for an Arabic translation by a translator licensed by the Ministry of Justice, with the source document authenticated through the prescribed chain first.	The licensed translator's stamp and licence number, signature, date and a reference to the already-authenticated source document.	The common order is Thai-side authentication, then the UAE mission, then authentication inside the UAE, then translation by a licensed translator. Confirm the order with the end recipient each time.
Thailand (foreign documents coming in)Department of Consular Affairs, MFA	A foreign document for use in Thailand is normally authenticated in its country of origin and by the Thai mission there, then translated into Thai or English for submission to the Department of Consular Affairs on the receiving body's terms.	A translation covering every seal and signature on the original, the translator's name, and a layout that can be compared against the source.	Once the Apostille Convention applies to Thailand on 28 February 2027, documents from other parties will carry an Apostille instead of the two-step chain — but the translation requirement still belongs to the Thai receiving body.

10 elements we put on every certification page

A statement that the translation is accurate and complete against the attached source

Most authorities look for this line before reading the content. Without the word 'complete', the officer cannot tell whether anything was left out.

The translator's full name and an actual signature

An unsigned or anonymous certification has no owner, which fails every country that ties reliability to an identifiable person.

The translator's qualification or registration number, such as a NAATI practitioner number or a sworn-translator registration

Countries with a central register verify the number directly; countries without one read it as evidence of competence.

A reachable address and contact channel

Several countries name contact details explicitly because the officer must be able to reach the translator when a doubt arises.

The date of translation

Some bodies apply an age limit counted from issue or from translation. Without a date there is no way to show the file is inside the window.

A reference to, and physical attachment of, the source copy

A free-standing translation cannot show which document it came from; stapling it to the copy or citing the document number closes that gap.

Bracketed descriptions of seals, signatures and handwritten notes

The receiving officer needs to see where seals and signatures sit on the original; omitting them makes the document look uncertified.

Personal-name spelling matched to the passport across the whole bundle

Different spellings inside one bundle are the single most common cause of return in immigration filings.

Not using the applicant, a relative or the applicant's representative as translator

Some countries state this prohibition outright, on the view that such a translator has an interest in the outcome.

Preserving the original's pagination and ordering in the translation

When the officer compares page by page, matching order speeds the check and cuts follow-up questions.

16 questions on translations filed abroad

Does an Australian visa always require a NAATI translator?: The Department of Home Affairs splits the rule by where the work is done: inside Australia the translator should be NAATI-certified; outside Australia the translator must show their name, address, contact details and qualifications on the translation. Both routes aim at a traceable translator.
What does USCIS require in a translation?: 8 CFR 103.2(b)(3) requires a full English translation of any foreign-language document, together with the translator's certification that they are competent to translate from that language into English and that the translation is accurate. The rule does not require registration with any body.
Can I translate my own documents?: It depends on the destination. Canada states plainly that it will not accept a translation by the applicant, a family member or the applicant's representative, and New Zealand likewise excludes applicant- or family-made translations. Countries that set translator qualifications exclude it by implication. Use an independent translator.
Will Canada accept a translation by a non-certified translator?: IRCC sets out two routes: a translation by a certified translator, or a translation by a non-certified translator accompanied by an affidavit sworn before an authorised official. The bar on the applicant and family translating applies to both.
Does the United Kingdom have sworn translators?: Not in the continental sense. GOV.UK therefore specifies the certification's contents instead: a confirmation of accuracy, the date, the translator's full name and signature, and their contact details.
How do Germany, France and the Netherlands differ on who may translate?: All three tie the translation to a state register: Germany to court-sworn or court-authorised translators in the national register, France to experts listed with a court of appeal, the Netherlands to the Rbtv register. What differs is the register and how you search it, not the principle.
Should I translate before or after legalisation?: There is no single answer. Some missions want the Department of Consular Affairs' seal to appear inside the translated set, so certification comes first; other bodies accept a separate translation. The safe move is to ask the end recipient whether the seals must appear in the translation before work starts.
Can Thai documents carry an Apostille yet?: Not yet. Thailand deposited its instrument on 30 June 2026 and the Convention enters into force for Thailand on 28 February 2027. Before that date no Thai authority can issue an Apostille and the existing legalisation chain still applies.
Why must the translation describe what is on the seals?: Because the receiving officer cannot read the original and judges completeness from the translation. If the translation does not say which authority's seal sits where, the file reads as an uncertified copy.
What if the name spelling does not match the passport?: Follow the passport spelling consistently across every translation in the bundle and add a translator's note recording the spelling as it appears on the original. The officer then sees one person rather than having to guess.
How should a foreign document be translated for use in Thailand?: The usual route is authentication in the country of origin and by the Thai mission there, then translation into Thai or English for the Department of Consular Affairs on the Thai receiving body's terms. Check with that body which language and which level of certification it wants.
What kind of translator does the UAE require?: Official use in the UAE generally calls for an Arabic translation by a translator licensed by the UAE Ministry of Justice, with the source document already authenticated through the prescribed chain — commonly Thai-side authentication, then the UAE mission, then translation at destination.
Does a translation expire?: The translation itself has no general statutory life, but many receiving bodies set an age limit on the source document such as a civil-status certificate or a company affidavit. When the original falls outside that window its translation goes with it, so ask the recipient for the timeframe before ordering.
Must every page be translated, including blank ones?: Translate every page carrying text, a seal or a signature, and mark pages without content as blank in a note. The page count then matches the original, which is what an officer counts before reading.
If a translation is returned, must everything start again?: Usually not: returns most often stem from a certification missing an element, a name spelled differently, or a dropped page — all fixable in place. Where the cause is that the translator does not meet the destination's requirement, the file has to be redone by a qualifying translator.
How can the translator's status be checked?: Countries with a central register let you search it yourself — a NAATI practitioner number, Germany's court interpreter and translator register, the Dutch Rbtv. Where there is no central register, the contact details on the certification are the verification route.

8 transliteration systems — the same person must read as the same person

Documents bounce far more often over a name spelled two ways, a Buddhist-Era year read as Gregorian, or an identifier retyped incompletely, than over a mistranslated sentence. This table cites each body's published standard. No fees or processing times are stated, and nothing here is legal advice.

Writing system	Standard used	Issued by	Practical rule
Thai script → Latin script	Principles of Romanization for Thai Script by Transcription	Office of the Royal Society	The principles are a transcription: they do not mark tone and do not distinguish vowel length, so different Thai words can romanise to the same Latin string. For filings, always follow the spelling printed in the passport first and use the Royal Society principles as the reference only where no passport spelling exists.
National characters → machine readable zone (MRZ)	ICAO Doc 9303 Part 3 — recommended transliteration	International Civil Aviation Organization (ICAO)	The MRZ carries only A–Z, 0–9 and the filler <, so diacritics are dropped. The MRZ name can therefore differ from the visual page. Translators should read the visual data page rather than the MRZ, and add a translator note when the two differ.
Chinese characters → Latin script	Hanyu Pinyin (ISO 7098)	ISO, aligned with the PRC national standard	Pinyin is the international reference, but passports from Taiwan, Hong Kong or Singapore may use Wade-Giles or a Cantonese romanisation. Follow the passport spelling and keep the original characters alongside so the entry stays traceable.
Japanese script → Latin script	Hepburn (Hebon-shiki) as used for passports	Ministry of Foreign Affairs of Japan	Japanese passports default to Hepburn and generally do not render long vowels with a macron, so names that differ in Japanese can look identical in Latin script. Keep the passport spelling and retain the original characters.
Hangul → Latin script	Revised Romanization of Korean (2000)	Ministry of Culture, Sports and Tourism, Republic of Korea	The 2000 system is official for place names, but personal names frequently keep the holder's long-standing spelling such as Lee, Park or Kim, which does not always match the system. Follow the passport.
Cyrillic → Latin script	ISO 9	ISO	ISO 9 is a reversible one-to-one transliteration, while many passports use a phonetic transliteration instead. The two commonly disagree, so state in a translator note which system was used.
Arabic → Latin script	ISO 233	ISO	Arabic script does not write short vowels in ordinary text, so one name may appear as Mohammed, Muhammad or Mohamad across documents. Follow the passport spelling and always keep the original.
Latin script with diacritics	Retain source diacritics	Practice of each national registry	Names such as Müller, Nyström or Łukasz change identity in a registry when the diacritics are stripped. Reproduce the source form, and where the receiving system accepts only A–Z, show both forms in the translation.

Calendars, numbers and identifiers — 8 rules behind most returned documents

Buddhist Era (B.E.) years in Thai official documents

The Buddhist Era runs 543 years ahead of the Gregorian year: B.E. 2569 is 2026 CE. A translation should show the Gregorian year and keep the source year alongside, for example 2026 (B.E. 2569), so it can be checked against the original.

Risk if handled wrongly: Converting silently leaves the officer unable to verify the arithmetic; forgetting to convert puts the year 543 years out and gets the document returned immediately.

Day/month/year ordering

Write the month in words, or use the ISO 8601 form YYYY-MM-DD consistently throughout. Avoid 03/08/2026, which reads two ways.

Risk if handled wrongly: A month-first reader gets a different date of birth, which then fails to match the immigration record.

Thai numerals ๐–๙ in the source

Render them as Arabic numerals in the translation, preserving every digit in order. Do not regroup them or drop leading zeros.

Risk if handled wrongly: Dropping a leading zero makes a registration or document number stop matching the source and breaks verification.

The 13-digit Thai national identification number

Copy all thirteen digits in order. The final digit is a check digit computed from the preceding twelve, so a typo or a transposition is detectable and fatal. If separators are used, mirror the source.

Risk if handled wrongly: A single wrong digit fails the check-digit test and casts doubt on the whole bundle.

Monetary amounts and currency

Keep the original amount. Never convert an exchange rate inside a translation, and name the currency with its ISO 4217 code such as THB, AUD or USD so the various dollars are not confused.

Risk if handled wrongly: Converting inside the translation makes it differ from the source, contradicting the certification that it is accurate and complete.

Decimal and thousands separators

German, French or Italian sources may use a comma as the decimal mark, as in 1.234,56. An English translation should render 1,234.56 and note in a translator note that only the separator convention changed.

Risk if handled wrongly: Read the wrong way, the amount is off by a factor of a thousand — serious in financial and court filings.

Address ordering

Thai addresses run from the smallest unit upward: house number, moo, soi, road, tambon or khwaeng, amphoe or khet, province, postcode. Keep that order in the translation and label the units, for example Tambon, Amphoe, Changwat, so the two can be compared line by line.

Risk if handled wrongly: Re-ordering to the destination's convention stops the officer from matching the translation line by line against the source.

Honorifics and ranks

Nai, Nang and Nangsao map directly to Mr, Mrs and Miss. For military, police and government titles with no exact equivalent, transliterate and gloss in brackets rather than substituting a foreign rank that merely looks similar.

Risk if handled wrongly: Mapping ranks across systems asserts a status the source never stated, which adds content beyond the translation.

Translator-note conventions for 7 situations

A seal or stamp is faint or illegible: Write [seal: illegible] rather than guessing the wording, and state where the seal sits on the page.
A signature appears with no printed name: Write [signature] and transcribe a printed name only where the source actually shows one.
The source contains a spelling error or an internal contradiction: Reproduce the error as it stands and flag it in a translator note. Do not silently correct it: the translation must mirror the source.
The page carries a barcode, QR code or watermark: Record that the element exists and where it appears, without decoding its contents.
The source runs to several pages: Number the pages as page x of y in both the translation and the certification so a missing page is visible.
The source is already bilingual: Translate both parts, and where the two source languages disagree, record the discrepancy in a note instead of choosing one.
Page layout matters: ISO 2384 on the presentation of translations calls for the translation to reflect the source's structure — heading order, tables and the position of elements — so the two can be compared.

Questions on names, dates and numbers in translations (12)

How far apart are the Buddhist and Gregorian years, and how should a translation show them?

The Buddhist Era is 543 years ahead of the Gregorian year, so B.E. 2569 is 2026 CE. The verifiable convention is to lead with the Gregorian year and keep the source Buddhist year in brackets, so the officer sees both the converted figure and the original.

My passport spelling does not match the Royal Society romanisation. Which one should be used?

Use the passport spelling, because the receiving authority matches the name against the travel document actually filed. The Office of the Royal Society principles are a transcription reference for cases with no pre-existing official spelling. Where the two differ, the translator should note which spelling came from which source.

Two documents spell the same name differently. What now?

Do not harmonise the spellings inside the translations, because each translation must match its own source. Translate each document as it stands and resolve the difference with an identity document such as a registrar's same-person certificate or a properly witnessed declaration. Contact our staff by phone, LINE or email to check which form the destination accepts.

Can a translator take the name from the passport MRZ line?

It should not be the source. ICAO Doc 9303 limits the MRZ to A–Z, digits and the filler <, so diacritics are stripped and long names may be truncated. The visual data page is the name to use, and any difference between the two belongs in a translator note.

Should a translation convert currency for the reader?

No. The certification states that the translation is accurate and complete against the source; inserting a figure derived from an exchange rate adds information the source never carried. Keep the original amount and name the currency with its ISO 4217 code, such as THB or AUD.

Must all thirteen digits of the Thai ID number be copied?

Yes, every digit in the original order. The last digit is a check digit derived from the preceding twelve, so a typo or transposition is detectable and will fail verification.

What should be done when a seal in the source is illegible?

Mark it as [seal: illegible] together with its position on the page. Never guess the wording: a guessed reading becomes a statement the translator has certified as accurate with nothing behind it.

Should a Thai address be re-ordered into the destination's format?

No. Keep the source order from the smallest unit upward and label the units — Tambon, Amphoe, Changwat — so the officer can compare the translation line by line against the civil-registration document.

Should a Thai military or police rank be mapped to a foreign rank?

Not across systems, because rank structures do not line up. The safe approach is to transliterate the Thai rank and gloss it in brackets, leaving interpretation to the receiving system.

What is wrong with writing 03/08/2026 in a translation?

It reads as either 3 August or 8 March depending on the reader's convention. The fix is to write the month in words, or to use the ISO 8601 form YYYY-MM-DD consistently throughout the document.

The source has a typo — should the translator correct it?

No. Reproduce it and add a translator note pointing to the doubt. A silent correction makes the translation differ from the source, contradicting the certification of accuracy and completeness, and it becomes a credibility problem the moment the documents are compared.

How does name and date handling relate to Thailand's Apostille?

Not directly, but they sit in the same chain. Thailand deposited its instrument of accession on 30 June 2026 and the Apostille Convention enters into force for Thailand on 28 February 2027. Before that date no Thai authority issues an Apostille and the Department of Consular Affairs certification followed by destination-embassy legalisation still applies. Either way, names and dates in the translation must match the source, because a certification attests only to a signature and seal — never to the accuracy of the content.

8 receiving venues — what each one needs attached to the translation

Thai court proceedings run in Thai, so a foreign-language document is filed with a Thai translation under Civil Procedure Code section 46, and the court may order the translation certified as correct. Fees and timetables belong to the courts and agencies and change.

Receiving venue	What it receives	Translation rule	Certification	Watch out
Courts of Justice — civil case	The original or a certified copy with a Thai translation attached.	Proceedings are conducted in Thai, so a foreign-language document is filed with a Thai translation (CPC s.46).	The translator signs a statement of correctness; the court may order further certification.	The other side may dispute wording — build a case glossary from the first filing.
Courts of Justice — criminal case	Case documents with translations, plus interpreting when a party does not use Thai.	The civil procedure rules apply so far as they are not inconsistent (CrPC s.15).	Translations are signed by the translator; the courtroom interpreter is a separate role.	Request the interpreter through the court in advance, not at the bench on the day.
Juvenile and Family Court	Petitions, orders and civil-status documents with translations.	Names and relationships must match the passport and the civil registry exactly.	Translator-certified, and usually legalised as well when the order will be used abroad.	For overseas use, obtain the court-certified copy before starting the legalisation chain.
Office of the Attorney General — Central Authority	Mutual-assistance requests and the supporting dossier.	The requested State or the applicable treaty fixes the target language — not our convenience.	Each translation carries a certification and matches the dossier index item by item.	Dossiers run to hundreds of pages — lock the glossary before translation starts.
Legal Execution Department	Judgments, writs and asset documents, translated where they are foreign-language.	Figures, amounts and asset particulars must match the source to the last digit.	Translator-certified, filed together with a certified copy of the source.	Debtor names spelled differently across documents stall enforcement.
Rights and Liberties Protection Department, MoJ	Assistance applications and supporting documents.	A foreign-language applicant document needs a Thai translation with it.	Signed by the translator with contactable details.	Do not abridge parts that look irrelevant — the agency needs the whole document.
District office — family-status registration	Foreign orders or registrations with a legalised Thai translation.	Certified abroad, endorsed by the Royal Thai Embassy, then translated into Thai and legalised by the DCA.	The registrar looks for the DCA legalisation stamp on the translation.	Filing a translation that has not yet been legalised is the most common bounce here.
Foreign receiving authority	A certified Thai judgment or order with translation and a complete stamp chain.	Some States require a translator registered locally — ask before starting.	DCA legalisation, then the destination embassy.	No Thai authority can issue an Apostille until the Convention enters into force for Thailand on 28 February 2027.

Why translations bounce, and how to fix them before the hearing

Cause	Surfaces at	Remedy
No translator certification attached	At the filing counter	Add a certification page naming the translator, language pair, page count, date and signature.
Name spelling differs from the passport or civil registry	During the agency or registrar's document check	Adopt the passport spelling and add variants in brackets with a translator's note.
Case or reference number transcribed wrongly	At case-registry or dossier review	Verify digit by digit and keep the source numbering format unchanged.
Incomplete translation — seals or reverse sides skipped	When a party or the agency collates pages	Render every element including seals, signatures and marginalia, tagged like [seal].

16 direct answers

Will a Thai court accept an English document with no translation?

As a rule no. Proceedings run in Thai, so a foreign-language document is filed together with a Thai translation under Civil Procedure Code section 46, and the court may order the translation certified as correct.

Who certifies a translation for court filing?

The translator signs a statement of correctness giving name, language pair, page count and date. Thailand has no state sworn-translator register as in Europe, so the court weighs the certifier's credibility and may order further certification.

Is a foreign judgment directly enforceable in Thailand?

No. Thailand has no direct-recognition regime, so the successful party normally files a fresh action in a Thai court, using the certified foreign judgment and its Thai translation as evidence.

How does a foreign arbitral award differ from a judgment?

A foreign arbitral award has a statutory enforcement route under Thai arbitration law reflecting the New York Convention, unlike a foreign court judgment, which has no direct route.

Must the whole document be translated, or only the part relied on?

Translating in full is safest. A partial translation invites an objection that context was cut. If a partial rendering is unavoidable, state its exact scope in the certification.

Can the courtroom interpreter also be the document translator?

They are distinct roles with different skills. One person may sometimes cover both, but tell the court plainly and book the interpreter in advance through the court, naming the exact language or dialect.

What is the first step to use a Thai judgment abroad?

Start by obtaining a court-certified copy of the judgment and, where the destination asks for it, a certificate that the case is final. Translation, legalisation and the destination embassy follow.

Can Thailand issue an Apostille on court documents yet?

Not yet. The Convention enters into force for Thailand on 28 February 2027. Until then, court documents for overseas use still pass through the Department of Consular Affairs and then the destination embassy.

Can the other side challenge our translation?

Yes, and it is routine in document-heavy cross-border cases. The court may order a fresh translation or ask the translator to explain. The defence is one consistent glossary across the whole file from the first filing.

Should Buddhist-era dates be converted to Gregorian?

Show both, e.g. 2 August 2026 (B.E. 2569). Silently converting without keeping the source form makes collation hard and is a frequent source of objections.

Which language must a mutual-assistance request be translated into?

Whatever the requested State or the applicable treaty specifies — not automatically English. Confirm with the Central Authority, the Office of the Attorney General, before translating the whole dossier.

How is a foreign divorce recorded at a Thai district office?

Certify it in the country of origin and at the Royal Thai Embassy there, translate it into Thai, have the Department of Consular Affairs legalise the translation, then file it with the district registrar.

Who bears the cost of a court interpreter?

It depends on the case type and the court's direction in that case, so never assume it is free or always covered. Ask the hearing court directly as soon as the date is known.

How should files be prepared for electronic filing?

Scan from the originals so seals and signatures read clearly, paginate to match the index, and pair each translation with the source page it renders so staff can collate in one pass.

How far ahead of a hearing should translation start?

Plan backwards from the date, leaving room for at least one correction round and for certification steps outside our control. Multi-hundred-page dossiers should start weeks, not days, ahead.

What if a translation bounces just before the hearing?

Fix only the flagged items, file the corrected translation with a note of exactly what changed, and if time genuinely runs out, raise the difficulty with the court early rather than staying silent until the day.

8 language and script groups — what changes when the source is not English

When the destination is a Thai court or agency, translate directly into Thai: proceedings run in Thai under Civil Procedure Code section 46 and the court may order the translation certified as correct. Requirements, fees and timetables belong to those bodies and change.

Language / script	Typical source form	Rendering rule	Certification path	Watch out
Chinese (simplified / traditional)	Household register, company certificates, judgments, red company chops.	Keep the Chinese name with pinyin and a Thai transliteration in brackets; tag every [seal].	Translator certification, then the certification chain the destination requires.	Simplified and traditional copies can spell a name differently — pick one form and add a translator's note.
Japanese	Koseki family register, seal-registration certificates, court orders.	Surname precedes given name in the source — keep the order and label which element is the surname.	Translator certification; legalisation only when the bundle goes on abroad.	Era years such as Reiwa must always be shown alongside the Gregorian year.
Korean	Family-relation certificates, residence certificates, judgments.	Transliterate names as they appear in the passport, not by the translator's own system.	Translator certification, then the receiving authority's chain.	Different romanisation systems make one person look like two in the same file.
Arabic	Marriage records, status certificates, Shariah-court documents.	Show the Hijri date alongside the Gregorian date and keep every element of the name intact.	Certified at origin and by the Royal Thai Embassy, then translated into Thai and legalised by the DCA.	Dropping patronymic elements breaks the match with the passport and triggers a bounce.
Burmese, Lao, Khmer, Vietnamese	Birth and marriage records, identity cards, employment contracts.	Some systems have no surname — say so in a translator's note rather than inventing one.	Translator certification, then whatever chain the receiving Thai authority requires.	Phonetic guesswork spells the same person differently on every page — anchor on the passport.
Russian and other Cyrillic-script languages	Birth and marriage records, single-status certificates, judgments.	Keep the patronymic in full and reproduce registry numbers in the source format.	Certified at origin and by the Royal Thai Embassy, then translated and the translation legalised.	Omitting the patronymic makes the translated name diverge from the source.
German, French, Spanish	Civil-status documents, judgments, powers of attorney.	Some States require a locally registered sworn translator — ask the destination before starting.	Outbound from Thailand: translator certification, DCA legalisation, then the destination embassy.	A translation made in Thailand can be refused where the destination insists on its own registered translator.
Dialects and low-resource languages	Statements, interview records, supporting documents in an application.	Name the language and dialect precisely from the outset — not just 'Burmese' but the dialect actually spoken.	The translator or interpreter signs with contactable details.	Naming the wrong language means no interpreter is found in time and the hearing is adjourned.

8 specialised cross-border matters — and the channel each one travels

Matter	Channel	Translation burden	Legal basis	Watch out
Wrongful removal of a child / return application	Filed through the Central Authority, the Rights and Liberties Protection Department, MoJ.	The application, foreign orders, evidence of the child's habitual residence, and relationship documents.	The 1980 HCCH Convention on the Civil Aspects of International Child Abduction, to which Thailand is a Contracting State.	Outcomes rest with the court; a complete, faithful bundle keeps the matter moving but guarantees nothing.
Cross-border custody and contact	The Juvenile and Family Court, plus the relevant registries.	Foreign orders, travel-consent letters and civil-status documents.	Civil Procedure Code s.46 requires a Thai translation for a foreign-language document.	A child's name spelled differently on the birth certificate and the passport is a frequent bounce.
Cross-border succession	The court with jurisdiction over the asset or domicile, plus the asset registries.	The will, death certificate, heirship evidence and title documents.	Foreign-made documents complete their certification chain first, then are translated and the translation certified.	Overseas heirs should give a power of attorney broad enough to cover every step from the start.
Enforcing a foreign arbitral award	A petition to the Thai court with jurisdiction.	The award and the arbitration agreement, with a Thai translation certified as the statute prescribes.	The 1958 New York Convention, to which Thailand is a party, together with the Arbitration Act B.E. 2545.	Statutory time limits apply to enforcement — check with counsel before translating the whole set.
Mutual legal assistance in criminal matters	Through the Central Authority, the Office of the Attorney General.	The request and the full dossier in the language the requested State or treaty specifies.	Channel and language are fixed by domestic law and the applicable treaty, not by the parties' convenience.	Dossiers run to hundreds of pages — lock the glossary and case-number format before translation starts.
Extradition	Through diplomatic channels and the Central Authority as the law provides.	Warrants, the request, evidence and identity documents.	Governed by the extradition legislation and any applicable treaty.	Case content is confidential — put a written confidentiality undertaking in place with the translation team.
Trafficking victims and rights protection	The Rights and Liberties Protection Department, MoJ, and the investigating officers involved.	The application, statements, identity papers and employment records.	A foreign-language applicant document is filed with a Thai translation.	Identify the victim's actual dialect so an interpreter can be arranged in time.
Migrant-labour disputes	The Labour Court and the relevant labour-protection offices.	Employment contracts, pay records and the worker's statements.	Proceedings are in Thai, so documents in another language are filed with Thai translations.	Bilingual contracts can diverge — flag the differences in a translator's note rather than choosing a side.

16 direct answers

Should a Chinese document be translated into Thai, or into English first?

Translate directly into Thai when the destination is a Thai court or agency, because proceedings run in Thai under Civil Procedure Code section 46. Relaying through English adds an unnecessary layer of drift.

What if the passport spelling differs from the source document?

Adopt the passport spelling in the translation, put other spellings in brackets, and add a translator's note that they refer to the same person. Some authorities additionally ask for a same-person affidavit.

Must Hijri or Japanese era dates be converted?

Show both: keep the source form and add the Gregorian equivalent. Converting and discarding the original form stops staff collating against the source and invites objections.

Do Chinese chops or Japanese hanko seals need translating?

Yes — mark every one, for example [seal: text on the seal]. Skipping seals makes the translation incomplete and it is usually bounced when staff collate the pages.

Is Thailand a party to the Hague Child Abduction Convention?

Yes — Thailand is a Contracting State to the 1980 HCCH Child Abduction Convention, and its Central Authority is the Rights and Liberties Protection Department, Ministry of Justice. Party status is verifiable in the HCCH status table.

Can a foreign arbitral award be enforced in Thailand?

Yes, by petitioning the Thai court with jurisdiction. Thailand is a party to the 1958 New York Convention and enforcement follows the Arbitration Act B.E. 2545, which requires a certified Thai translation of an award and agreement in a foreign language.

How should a several-hundred-page dossier be started?

Lock the glossary, party names and case-number format before the first page is translated, then split the work into batches. Retrofitting inconsistent terminology across a whole dossier costs far more than setting the standard up front.

The destination insists on its own sworn translator — what then?

Follow the destination's rule. Several European States accept only a locally registered sworn translator, so we complete the source and the Thai-side certification chain, and the final translation is produced in the destination country.

How is a Burmese name with no surname entered on a Thai form?

Never invent one. Enter the full name exactly as the passport shows it and add a translator's note that the source naming system has no separate surname.

How is a dialect interpreter requested for a hearing?

Tell the hearing court as soon as the date is known and name the language and the dialect precisely, not just the country — different dialects need different interpreters.

Can a will made abroad be used in Thailand?

It can support a filing in a Thai court, but it must first be certified in the country where it was made and by the Royal Thai Embassy, then translated into Thai with a certification. Its legal effect is decided case by case by the Thai court.

What should a translator do when a bilingual contract diverges?

Not pick a side: flag the divergence in a translator's note and leave it as an issue for the parties and the court. If the contract has a governing-language clause, cite it in the note.

Which language does a mutual-assistance dossier take?

Whatever the requested State or the applicable treaty prescribes — not automatically English. Confirm with the Central Authority, the Office of the Attorney General, before translation begins.

Case papers are confidential — can they go to a translation team?

Yes, with a written confidentiality undertaking, access limited to those who need it, and a controlled file-transfer channel — not public links or unmanaged chat apps.

Can an Apostille be obtained for a Thai court document yet?

Not yet. The Apostille Convention enters into force for Thailand on 28 February 2027; before that date outbound documents still need Department of Consular Affairs legalisation followed by the destination embassy.

How much lead time does a low-resource language need?

Always more than a common pair, because the pool of translators and interpreters who can certify is small. Name the language and dialect on day one and plan backwards from the hearing date; we do not promise timetables on behalf of a court or agency.

Who actually reads your translation — 10 bodies in the justice chain

Thai court proceedings are conducted in Thai, so a foreign-language document is filed with a translation under Civil Procedure Code section 46 and the court may order it certified as correct. Conditions, fees and timetables belong to the courts and agencies and can change.

Body	Role	What it verifies	Bundle note
Inquiry officer, Royal Thai Police	Takes the complaint and statements and assembles the investigation file before it goes to the prosecutor.	That every cited document is readable in Thai, that the provenance of a file or screenshot is stated, and that whoever certified the translation can be contacted.	Pair every translation with a clean original or copy, and index them in the same order the complaint refers to them.
Department of Special Investigation	Investigates cases designated as special cases, often economic and cross-border matters.	Continuity across a financial document set, and consistent rendering of person and company names across every language in the file.	Attach a name-and-term glossary so every document in the set uses one rendering from the start.
Public prosecutor, Office of the Attorney General	Decides charges and conducts the case in court, and is the Central Authority for mutual legal assistance and extradition.	Whether the translation set is complete enough to be relied on in court, and — in cooperation files — the language the requested State or treaty prescribes.	Confirm the target language with the Central Authority before a large set is translated, so the work is not repeated.
Civil and provincial courts	Hear general civil matters, including cases where foreign documents are documentary evidence.	That documents are in Thai as Civil Procedure Code section 46 requires, and the court may order the translation certified as correct.	Bind original and translation as one exhibit and number them to match the list of evidence.
Labour Court	Hears employer–employee disputes, where the contract and internal policies are often in English.	That the employment contract, termination letter and company policies relied on are translated consistently as one set.	Translate the whole instrument even when only a clause is relied on; the surrounding context is routinely disputed.
Juvenile and Family Court	Hears family matters, parental power, adoption and juvenile cases.	That names, dates of birth and stated relationships agree across the civil-registration record and every foreign document.	Where a passport spelling and a register spelling differ, carry a translator's note explaining it from the outset.
Central IP and International Trade Court	Hears intellectual-property and international-trade cases, where most of the record is foreign-language.	That technical terms and contract wording are rendered identically throughout the file, not varied between documents.	Fix a glossary before work begins and hold the whole team to it for the life of the case.
Central Bankruptcy Court and Legal Execution Department	Hear insolvency and rehabilitation matters, while the Legal Execution Department carries out enforcement and asset administration.	A foreign creditor's proof of debt, power of attorney and company certificate, each with a complete authentication chain.	A power of attorney executed abroad needs the origin country's chain and Thai embassy legalisation before it is translated for use in Thailand.
Administrative Court	Hears disputes between private parties and State agencies; a separate jurisdiction from the Courts of Justice.	Translations of the administrative order, the correspondence with the agency and any procurement papers relied on.	Preserve reference numbers, dates and agency names exactly; never render an agency name differently from its official name.
Rights protection, probation and corrections	Handle victim and witness rights, probation supervision and post-sentence corrections.	Identity and relationship documents, plus any medical or financial papers supporting the application.	Include an embassy letter with its translation when the applicant is a foreign national; it is routinely requested later.

8 procedural stages — how the translation task changes

Stage	What is due	Translation trigger	Planning note
Before a complaint or a claim is filed	The set that opens the matter	Anything cited in the complaint or the claim must be readable in Thai.	This is the most flexible window; spend it fixing the document set and the glossary, because later corrections cost more.
Filing the claim or the defence	The pleading with its exhibits	Foreign-language exhibits are filed together with their Thai translations.	A defence has a statutory deadline; start translation the day the summons arrives rather than near the end of the period.
Issue settlement and the list of evidence	The list of witnesses and documents to be relied on	Documents left off the list can be challenged later, so the translation set should already be complete when the list is drawn.	This is the cheapest point to proof-read the whole translation set once, before evidence begins.
Evidence hearings	Documentary evidence and interpreting in the courtroom	The court may order a translation certified as correct, or the other side may dispute specific wording.	Book interpreting early for scarce languages, and keep whoever certified the translation reachable on the hearing date.
Judgment	The judgment and any papers that travel onward	To use a judgment abroad you need a certified copy, a translation and the destination authentication chain.	No Apostille is available in Thailand until the Convention enters into force on 28 February 2027, so the Department of Consular Affairs plus destination-embassy route still applies.
Appeal and Supreme Court	The appeal or petition with supporting papers	New material relied on at this stage needs translation, and should keep the same wording used at first instance.	Inconsistency between instances is an opening for challenge; carry the original glossary forward.
Enforcement	The enforcement application and proof of entitlement	A foreign power of attorney and company certificate need their authentication chain before translation for use here.	The overseas authentication chain is the slowest step; start it in parallel with drafting the application.
After finality, using the outcome abroad	The bundle sent to the receiving authority	Language and form follow the receiving authority's requirements, not the Thai court's.	Get the receiving authority's requirements in writing before starting, so the chain is not paid for twice.

6 checks before the bundle leaves your hands

One glossary for the whole case

Names and contract terms rendered differently between documents are the most common opening for a challenge at the evidence stage.

A clean original or copy sits with every translation

The reader must be able to compare page to page; without the paired original, files are commonly bounced at the intake desk.

Exhibit numbers match the list of evidence and the pleading

Mismatched numbering stops the clerk from collating the file and confuses references during the hearing.

Whoever certified the translation is reachable on the hearing date

The court may order the translation certified as correct, a power Civil Procedure Code section 46 expressly contemplates.

Never silently reconcile a discrepancy inside the translation

If originals disagree, the translator's duty is to mirror the source and add a note, not to make the documents agree.

Complete the overseas authentication chain before translating

Authentication usually adds seals or pages; translating first means paying for a second round.

FAQs on translations for courts and justice agencies

Can an English document be filed in a Thai court untranslated?

As a rule no. Proceedings are in Thai under Civil Procedure Code section 46, so a foreign-language document is filed with a Thai translation, and the court may order that translation certified as correct.

Must the whole document be translated, or only the clause relied on?

In the files we prepare, translating the whole instrument is safer, because the other side routinely relies on the surrounding context. The scope a court requires is ultimately a matter for that court.

What if the other side disputes the accuracy of a translation?

Have the original, the glossary and the certifier ready to address the disputed wording point by point. The court may order re-certification or a further translation; the outcome is for the court to decide.

Do the Labour Court and the civil courts apply different translation standards?

The Thai-language rule is the same; the document set differs. Labour matters usually turn on an English contract, a termination letter and internal policies, which should be translated as one consistent set.

What does a foreign creditor need to file a proof of debt?

Typically the evidence of debt, a company certificate and a power of attorney. If executed abroad these need the origin chain and Thai embassy legalisation first, then a Thai translation. The exact filing requirements are set by the court and the Legal Execution Department.

Can a power of attorney signed abroad be used for enforcement in Thailand straight away?

In our experience it must be authenticated in the country of signature and legalised by the Thai embassy there, then translated into Thai. Acceptance in any given matter still rests with the receiving body.

How far ahead should a court interpreter be arranged?

The scarcer the language, the more lead time. Name the language and dialect on day one and plan backwards from the hearing date; we do not commit to timetables on a court's behalf.

How should chat logs and emails be translated for evidence?

Translate what is actually there: keep the timestamps, sender names and typographical errors, with translator's notes explaining slang or emoji that carry meaning. Do not smooth the text into clean prose.

Passport and register spellings differ — should the translator harmonise them?

No. A translation mirrors its source; where sources differ, carry a translator's note recording the difference. Silently harmonising undermines the credibility of the whole set.

What is needed to use a Thai judgment abroad?

Usually a court-certified copy, a translation in the language the destination requires, then Department of Consular Affairs legalisation and destination-embassy legalisation. Whether the judgment is given effect abroad is a question of that State's law.

Is an Apostille available for Thai case documents yet?

Not yet. The Apostille Convention enters into force for Thailand on 28 February 2027; before that date the Department of Consular Affairs plus destination-embassy route still applies.

How does the Administrative Court differ for documents?

It is a separate jurisdiction, and the record is typically administrative orders, correspondence and procurement papers. Reference numbers, dates and official agency names must be preserved exactly.

The prosecutor asks for extra translations mid-review — how is that handled quickly?

Reuse the glossary and layout from the first set so the whole file need not be re-checked, and label the additions clearly so they do not mix with the original set.

Case papers are confidential — how are they sent to a translation team safely?

With a written confidentiality undertaking, access limited to those who need it, and a controlled transfer channel — not public links or unmanaged chat apps.

A summons has arrived with little time — where should one start?

Start by identifying which documents the defence will actually rely on and translate those first, then the supporting material. Starting with the entire pile is what usually misses the filing deadline.

What must a foreign victim translate to apply for compensation?

Typically identity documents, medical records and evidence of loss, filed with the Rights and Liberties Protection Department. The conditions and required documents are set by that department and can change.

How to order a certified translation accepted by the MFA and embassies

How certified translation works in Thailand: translation plus a signed accuracy certificate for MFA legalisation, embassy filings, courts and overseas institutions — TH↔EN/ZH/JA/KO/FR/DE/RU/AR.

Typical time required: 2 days

Send the source document and choose the target language
Send a clear scan or photo of every page, state the target language and the purpose (MFA, embassy, court, university) so the correct certification format is applied from the start.
Read more about this step
Translation plus senior-translator QA
A registered translator produces the draft, then a senior translator checks legal and administrative terminology against the wording the MFA and embassies expect to see.
Read more about this step
Accuracy certificate issued, signed and sealed
A Certificate of Translation Accuracy is signed by the translator and the company and sealed, with the source document and translation bound together as one set per MFA practice.

Deep Context and Service Standards

Sourced from the Lawyer Act B.E. 2528 (1985), the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the Personal Data Protection Act B.E. 2562 (2019), the Hague Apostille Convention of 1961, and official publications of the Department of Consular Affairs (MFA).

Firm Overview and Practice Framework

Thai Notary Service is a full-service Thai law office providing document notarization, certified translation, legalization chain management, and international document consultancy. Our team includes Notarial Services Attorneys licensed by the Lawyers Council of Thailand under the Royal Patronage, and we operate offices in Bangkok, Greater Bangkok, and a partner network in every province across Thailand. We serve individuals, expatriates, cross-border couples, students, corporates, multinationals, and government agencies requiring documents with legal effect both inside Thailand and abroad.

All notarial acts follow the Lawyer Act B.E. 2528 (1985) Section 27 read with the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the sole legal basis authorizing Thai attorneys to certify documents comparable to a foreign Notary Public. Every attorney on our team has completed the accredited training and examination administered by the Lawyers Council and holds a verifiable registration number searchable on the Lawyers Council public registry.

By choosing a firm that houses Notarial Services Attorneys in-house, clients consolidate a multi-stage legalization chain under one accountable roof: attorney notarization, followed by Ministry of Foreign Affairs (MFA) legalization at the Department of Consular Affairs, followed by embassy or consular legalization for the destination country. Since 21 November 2024 the Kingdom of Thailand has become a party to the Hague Apostille Convention (Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents). Documents apostilled in Thailand are now accepted in more than 125 member states without embassy re-legalization, materially reducing turnaround time and cost.

General Information and Firm Framework — Deep Context

The firm operates under an ISO 9001:2015 quality-management framework and enforces data protection consistent with the Personal Data Protection Act B.E. 2562 (2019). All client documents are stored with AES-256 encryption at rest and in transit and are retained for ten years in accordance with lawyer-record obligations under the Lawyer Act.

Our team combines Notarial Services Attorneys, NAATI-certified translators, and legal specialists in intellectual property, taxation, cross-border family law, corporate law, and immigration law, together with a support team dedicated to documentation, translation, and government-agency liaison.

Fees are transparent and disclosed both on the website and in the pre-engagement quote, separating professional fees, government fees, travel disbursements (if any), and other line items. The firm issues VAT invoices and official receipts and accepts payment by bank transfer, credit card, PromptPay, and cash.

Trust Standards — PDPA, SLA, Quality Assurance

On data protection, the firm strictly follows the Personal Data Protection Act B.E. 2562 (2019), Sections 24, 26, and 27 — collecting, using, and disclosing personal data only to the extent necessary for the engagement, disclosing purposes, and obtaining consent from data subjects in advance. Clients retain the right to inspect, obtain a copy, rectify, erase, or withdraw consent at any time through the firm's Data Protection Officer (DPO). For clients in the European Union, processing follows GDPR Article 6 (lawful basis) and Article 46 (Standard Contractual Clauses).

Our Service Level Agreement targets an inquiry response within one hour during business hours (09:00–18:00, Monday to Saturday), attorney appointments within twenty-four hours, standard notarization within one business day (or two to three hours on express service), certified translation within three to five business days per ten A4 pages, MFA legalization within two business days on standard service (one business day express), and embassy legalization typically within three to fifteen business days depending on the mission's own policy.

Every deliverable passes a three-tier quality-assurance chain: (1) the responsible attorney or translator, (2) a Senior Attorney or department head reviewing substance and formatting, (3) a Quality Control desk performing the final pre-delivery check. Any firm-side error is remedied at no additional cost, and if a document is rejected by a government authority due to a firm-side error, we cover the entire re-filing fee.

Contact and Initial Consultation

Initial consultation is complimentary via Line @thainotary or by phone at 094-8958999. The team responds within one hour during business hours. Every inquiry is treated confidentially under the Lawyers Council ethics rules and the Personal Data Protection Act.
