Do foreign documents notarised in Thailand work overseas without apostille?
From 28 February 2027, when the Convention enters into force for Thailand, documents Apostilled at MFA Consular Affairs will be accepted in 130+ member states; until then the embassy chain applies. For non-member destinations, the chain remains Notary → MFA legalization → destination Embassy in Bangkok. NYC handles both routes end-to-end in 5–15 business days.

Frequently asked questions
Is a Thai notary equivalent to a US or UK notary?+
Functionally yes for signature and copy certification. However Thailand does not issue apostilles, so overseas authorities usually require MFA + embassy legalization on top of the notary seal.
Can you notarise a document written in English only?+
Yes. All NYC notaries are bilingual attorneys registered with the Lawyers Council; documents in English, Thai, or English-Thai bilingual are all accepted.
Do you offer remote / online notarisation?+
Thailand does not yet recognise remote online notarisation under law. We do offer video-witnessed drafting review before you attend in person, and mobile visits to your hotel or office.
Can you help with the full embassy legalization after notarising?+
Yes — that is the most common request. Ask for a bundle quote covering notary + MFA + destination embassy.

Frequently asked questions
- Does Thailand have notaries public?
- Thailand has no notary public in the common-law sense; the equivalent function is performed by a Notarial Services Attorney — a Thai lawyer who has completed the Lawyers Council of Thailand's notarial services course and is registered to certify signatures, copies, and statutory declarations. Foreign authorities routinely accept these certifications, and when the destination expects apostille-style authentication the certification is followed by MFA and embassy legalization.
- What documents can a Notarial Services Attorney certify?
- Commonly certified items include signatures on powers of attorney, affidavits and statutory declarations, certified true copies of passports and corporate documents, company resolutions and share transfer forms, sponsorship and consent letters, and the identity of a signatory for foreign banks, universities and courts. The attorney certifies the signing act or copy fidelity — not the truth of the content.
- Do I have to sign in person?
- Yes. The attorney must see the signatory in person together with the original passport or Thai ID before certifying a signature, which is the core safeguard of the service. Remote or scanned signatures cannot be certified. Mobile appointments at your office, condominium lobby or a nearby café are available if you cannot come to ours.
- How much does notarial certification cost and how fast is it?
- Attorney notarial certification starts at about THB 1,500 per document, with the final price depending on the number of documents, signatories and whether the appointment is mobile or out of hours. The certification itself is completed during the appointment; only the subsequent MFA and embassy steps add working days.
