Additional frequently asked questions

How long does an attested document stay valid?

The attestation itself has no expiry, but recipients such as embassies, banks and universities commonly require documents issued within the last 3–6 months. Always check the recipient's recency rule first.

What if the destination authority rejects the document?

Ask for the rejection reason in writing. Most rejections come from wording of the attestation clause, the order of the legalisation chain, or a translation that does not match the required format — each of which can be corrected without redoing the whole set.

Can the process be started from outside Thailand?

Document review, drafting the attestation wording and coordinating with authorities can all be done remotely. Only steps that legally require personal appearance must be completed before the attesting attorney or through a channel the destination accepts. Scope and requirements are confirmed case by case by phone, LINE or email.

Does Thailand have a Notary Public in the common-law sense?

Thailand has no common-law notary. The equivalent is a Notarial Services Attorney registered with the Lawyers Council of Thailand under Royal Patronage. Foreign authorities, embassies and universities generally accept this attestation where a notarised document is required. Scope and requirements are confirmed case by case by phone, LINE or email.

Do I have to sign in person before the attorney?

For signature attestation, yes — the signer must appear with an original passport or Thai ID card and sign in the attorney's presence. Certified true copies and certain fact attestations can be handled from originals without a fresh signature, depending on what the receiving authority requires.

Can the attestation be used abroad immediately?

It depends on the destination. Many countries additionally require legalisation by the Department of Consular Affairs, Ministry of Foreign Affairs, and sometimes by their own embassy in Bangkok. Confirm the receiving party's chain before starting so the work is not repeated.

In depth: the real requirements and why documents get rejected — Notary Public

Written from the competent authority's published rules, not marketing copy.

Notarial work in Thailand is performed by lawyers registered with the Lawyers Council of Thailand who hold the notarial services endorsement. Verifying that the certifier's registration is current is a step the document owner can and should perform before discussing wording or scheduling.

Conditions you actually have to clear

• For a true-copy certification, the original must be produced on the day; comparison against an image file is not accepted by most authorities.
• If the signatory cannot read the language of the instrument, an interpreter must be present and that fact recorded in the certificate.
• The signatory must appear in person with an unexpired passport or national ID card; a scan sent in advance cannot substitute for appearance.

Common causes of rejection

• A company affidavit older than the destination's accepted age leaves signing authority unproven as at the certification date.
• Re-binding the file or removing a seal after certification breaks continuity and forces the process to restart.

The safest approach is to obtain the receiving authority's requirements in writing first, then match the certificate wording and the chain order to them. If anything is unclear, send us the destination country and the intended use by phone, LINE, or email before any signing appointment.
