Notary for Visa Applications

Thailand has no notary public — it has Notarial Services Attorneys

Applicants raised in common-law jurisdictions arrive expecting a notary public in the English or American sense. Thailand does not have that office. What exists is the Notarial Services Attorney, a Thai lawyer licensed by the Lawyers Council of Thailand under its notarial services regulation and entitled to attest signatures, certify copies as true to the original, administer oaths and affirmations, and witness the execution of documents. The credential is a lawyer's licence with a notarial endorsement, and it carries a registration number that the receiving authority can check.

That distinction matters for visa work because the phrase on the checklist is usually 'notarised'. A consular officer in Bangkok knows what a Thai notarial attestation looks like. An officer at a university admissions office in Ontario may not, and will sometimes bounce a perfectly valid attestation because it does not resemble a notary seal from home. The fix is not a different signature; it is a clearly drafted attestation clause that states the attorney's authority and registration, in English, on the face of the document.

Notarisation is also not legalisation. A notarised copy is a statement about what the attorney saw. Where the receiving country needs a chain of authentication, the notarised document then goes to the Department of Consular Affairs and, until 28 February 2027 when the Apostille Convention takes effect for Thailand, on to the destination embassy in Bangkok.

Which visa documents actually need notarisation

How a session runs and what to bring

1. Send drafts before the appointment: Affidavit and declaration wording should be reviewed against the destination's prescribed form first. Redrafting at the desk is what turns a 20-minute appointment into two visits.
2. Bring originals, not copies: A true-copy certification requires the attorney to see the original. A copy of a copy cannot be certified, however clear it is.
3. Bring photographic identification for every signatory: Passports for foreign nationals, Thai ID cards for Thai signatories. The attestation records the identification relied on.
4. Sign in the attorney's presence: A signature already on the page can only be acknowledged, which some destinations do not accept in place of attestation.
5. Decide the onward chain at the same appointment: If MFA certification and embassy legalisation will be needed, the document set is assembled differently from the outset.

Language, translation and the order of operations

Where the underlying document is in Thai and the destination reads English, the sequence is: translate, then attest the translation and the translator's declaration, then send the bundle onward. Reversing that order produces a notarised Thai document with an uncertified English translation stapled to it, which is the single most common reason a bundle is returned from a European consulate.

For destinations that require the translation itself to be certified by the Department of Consular Affairs, the MFA has its own formatting expectations and will check the transliteration of names against the passport. We fix the transliteration once, at the start, and use it consistently across every document in the file, because a first name spelled two ways across a bundle reads as a discrepancy rather than a typo.

Common mistakes and how we avoid them

More questions we are asked

Is a Thai notarial attestation accepted internationally?

It is the recognised Thai equivalent and is routinely accepted, particularly once the attestation clause is drafted in English and, where required, carried through the MFA and embassy chain.

Can you notarise a document I email over?

A true-copy certification requires sight of the original. Signature attestation requires the signatory to attend. Drafting and review can be done remotely beforehand.

Do both parents need to attend for a minor's travel consent?

Both signatures normally need attesting. Where one parent has sole parental power, bring the court order or registration proving it and we draft accordingly.

Will an apostille replace this in 2027?

From 28 February 2027 the apostille will replace the destination-embassy step for member states. The notarial attestation itself remains the underlying act.

How long is a notarised document valid?

There is no statutory expiry, but receiving authorities commonly impose their own window, often three to six months. Check the destination's rule before you have documents attested early.
