Notarial Services Attorney (Notary Public) in Thailand: case studies, required documents and steps

In Thailand notarisation is performed by a Notarial Services Attorney licensed by the Lawyers Council of Thailand, not by a civil-law notary. The attorney verifies the signer's identity, witnesses the signature, and affixes a signed and sealed certificate. Most single-document jobs are completed the same day when the signer attends in person with valid photo ID and the final, unsigned document.

Documents most often involved

Step-by-step workflow

  1. Send the draft for review — Email or LINE the document and tell us who will receive it abroad. We check whether a signature witness, certified true copy, or affidavit format is the right certificate type.
  2. Confirm the certificate wording — The certificate text differs for signature witnessing, copy certification and declarations. We fix the wording before you travel to the office.
  3. Attend and sign before the attorney — Bring the original ID. The attorney checks identity, watches the signature, then signs, seals and records the act in the notarial register.
  4. Add legalisation only if the receiver asks — Some destinations require Ministry of Foreign Affairs and embassy legalisation after notarisation. That stage runs on the ministry's and embassy's own queues, typically a few working days each.
  5. Collect or receive by courier — Originals can be collected in person or sent by domestic or international courier with tracking.

Signature certification on an overseas share transfer form

Client group
Individual client
Location
Bangkok, Thailand
Documents
Share transfer form issued abroad · Passport · Company shareholder letter
Approximate turnaround
1–2 working days once the signer attends in person

What our team handled

  1. Confirmed with the receiving party whether a signature certification or a certified true copy was required
  2. Checked that the form was still unsigned so the signature could be witnessed in person
  3. Arranged an appointment where the signer attended with the original passport
  4. Issued the notarial certificate with signature, seal and register entry

Obstacles and how they were resolved

  • The first version had already been signed at home and had to be reprinted
  • The receiving party later asked for the notarial certificate to name the transaction, so the wording was adjusted before sealing

Process outcome: The signed and sealed set was handed over the same day, with a scan sent by email for the counterparty to pre-check before courier despatch.

Process note (illustrative): Confirming the exact certification wording with the receiving party before the appointment removed a second visit; asking for that wording in writing would have saved another half day.

Certified true copies of academic records for a foreign university

Client group
Foreign national client
Location
Chiang Mai, Thailand
Documents
Degree certificate · Academic transcript · Passport data page
Approximate turnaround
1–3 working days depending on page volume

What our team handled

  1. Compared each copy against the original page by page before certification
  2. Certified each page separately because the university required per-page endorsement
  3. Prepared a cover schedule listing every certified page for the applicant's file

Obstacles and how they were resolved

  • One transcript page was a re-issued duplicate with a different layout and had to be re-scanned
  • The university portal capped uploads by file size, so the scan set was re-exported at a lower resolution

Process outcome: A per-page certified set plus an indexed digital copy was delivered for upload and for the hard-copy submission.

Process note (illustrative): Certifying page by page from the start avoided a rejected upload; requesting the portal's file-size rules earlier would have avoided the re-export.

Affidavit of single status prepared before an overseas marriage

Client group
Foreign national client
Location
Phuket, Thailand
Documents
Affidavit drafted for the destination registry · Passport · Proof of address
Approximate turnaround
1–2 working days after the wording is agreed

What our team handled

  1. Reviewed the registry's template wording and the language it had to be sworn in
  2. Witnessed the oath and the signature, then issued the notarial certificate
  3. Explained the follow-on legalisation route required by the destination country

Obstacles and how they were resolved

  • The registry required the deponent's full name exactly as spelled in the passport, which differed from the draft
  • A previous marriage had to be referenced in the affidavit, adding a supporting document

Process outcome: The sworn affidavit was issued and the client continued to consular legalisation with a written step list from our team.

Process note (illustrative): Reading the registry template line by line before the appointment prevented a rewrite; collecting the previous-marriage document at intake would have shortened the visit.

Board resolution certified for an overseas bank account opening

Client group
Corporate client
Location
Nonthaburi, Thailand
Documents
Board resolution · Company affidavit · Director's passport
Approximate turnaround
2–4 working days including re-issue of the affidavit

What our team handled

  1. Verified that the signing director matched the company affidavit on record
  2. Witnessed the director's signature on the resolution and certified the accompanying corporate documents
  3. Bound and sealed the set so the bank received it as one certified bundle

Obstacles and how they were resolved

  • The company affidavit was older than the bank's acceptance window and had to be re-issued
  • The bank required an English rendering of the affidavit alongside the certified original

Process outcome: A single bound and sealed corporate bundle was delivered together with the English rendering for the bank's file.

Process note (illustrative): Checking the bank's document-age rule at intake avoided a rejected submission; asking about language requirements at the same time would have removed one handover.
