Practical playbook: Notarial Services Attorney (Thailand)

In Thailand notarisation is performed by a lawyer registered as a Notarial Services Attorney with the Lawyers Council, covering signature witnessing, true-copy certification and affidavits for use abroad.

Documents to prepare

  • Original document to be notarised
  • Passport or Thai ID card of every signatory
  • Company documents and authority evidence for corporate signings
  • Draft affidavit or declaration text, where applicable

Steps and method

  1. 1. Confirm what the receiving party needs

    Signature witnessing, certified true copy and affidavit are different acts with different wording.

    Typical timeframe: 1 day

  2. 2. Prepare and review the text

    Finalise the declaration wording before the appointment so nothing is edited after signing.

    Typical timeframe: 1–2 days

  3. 3. Sign before the notarial attorney

    All signatories attend in person with valid photo ID; the attorney records the act and affixes the seal.

    Typical timeframe: Same day

  4. 4. Onward certification if needed

    Many destinations also require MFA legalisation and an Apostille or embassy step after notarisation.

    Typical timeframe: 2–10 business days

Consultant tips

  • Ask whether the destination needs the notarial certificate in English, bilingual or the local language.
  • Corporate signings usually need a recent DBD company affidavit as proof of signing authority.

Pitfalls to avoid

  • Signing before the appointment invalidates a signature-witnessing act.
  • A Thai notarial act alone is often not enough abroad without the follow-on legalisation chain.

Thai notarial services attorney vs foreign notary public

Two different systems. The receiving party decides which is acceptable.

AspectThai notarial services attorneyForeign notary public
AuthorityLawyer registered with the Lawyers Council of ThailandNotary under that country's own law
Where usedDocuments executed in Thailand for use abroadDocuments signed in that country
Next stepOften consular certification or ApostilleAs required by the issuing country
What is certifiedSignatures, true copies, affidavitsAs permitted by local law

Doing it yourself vs having iVC manage the whole process

Both routes are valid. They differ in the time you spend, the risk of documents being returned, and whether an adviser reviews everything before submission.

AspectDo it yourselfManaged by iVC
Pre-submission reviewYou check against the agency's published requirementsAn adviser checks each document against the destination's rules first
Your timeYou travel, queue and follow up yourselfWe file and follow up; you receive progress updates
Rejection riskCommon causes: name spelling mismatch, expired documents, wrong certification orderWe check the usual rejection triggers at source and fix them first

We work as advisers, not just a document courier

More than 15 years of casework (since 2011) in translation, certification and visa document preparation shows us the patterns behind repeated rejections, so we plan around them from the start.

Case assessment first
We review the profile, destination country and receiving authority before recommending a certification route.
A document plan per person
We sequence what must be re-issued, translated first, and certified in which order.
Risks flagged early
We point out the usual rejection triggers, such as name spelling that differs from the passport or document age limits.
Follow-through to the end
Regular progress updates, and immediate options if the authority requests more documents.
Advice after completion
The same set is often reused in the next step; we check whether it still qualifies or needs re-issuing.

If you would rather not chase each step yourself, send the case details for an assessment first, then decide.
