Notarial Services

A notarial services attorney — a lawyer specifically registered with the Lawyers Council of Thailand for this work. It is the Thai equivalent of what other countries call notarisation, and foreign authorities accept it in that capacity. Our certifications are carried out by Pongsanan Taongern, Notarial Services Attorney No. 811/2569.

No — the point of the certification is that the attorney witnessed you sign it, so the signing happens in his presence. Bring the document unsigned, with your passport or ID. If you have already signed, the page simply gets signed again in front of him.

No, and the distinction matters. The certificate attests who signed and that they signed in the attorney’s presence — not that what the document says is correct. Foreign authorities know this; problems arise only when someone assumes certification launders the contents.

It depends entirely on the receiving country. Many require further legalisation by the Ministry of Foreign Affairs and then the destination’s embassy. Thailand acceded to the Apostille Convention on 30 June 2026, but it enters into force only on 28 February 2027 — so until then an apostille is still not available here and documents generally follow the existing chain. Ask the receiving body what it needs before you start — we then prepare the document to survive it. NOTARIAL_LIMITS

Your passport or Thai ID, the unsigned document, and — if you are signing for a company — the affidavit showing your authority. Certification itself is usually completed during the appointment; NOTARIAL_TIMEFRAME

Yes. The attorney certifies that the copy matches the original he has seen, so the original must be produced at the appointment. It goes home with you — that is the whole purpose of the exercise.

Most receiving bodies accept them, but some insist on originals or on their own certification chain, and many require the copy to be legalised further before use. Confirm with the receiving body first — a certified copy prepared for the wrong requirement is a wasted trip. NOTARIAL_LIMITS

More than you think you need. Receiving bodies keep them, applications get resubmitted, and a second appointment costs more than an extra set made during the first. Applicants routinely return for copies they could have taken the same morning.
