What is a Notary Public in Thailand, and can foreigners use one?

Thailand does not have a separate 'Notary Public' office like the US or UK. Instead, the Lawyers Council of Thailand licenses qualified attorneys as 'Notarial Services Attorneys'. They certify signatures, copies and affidavits with the same legal effect notarization carries abroad. Foreigners can use these services freely; documents are notarized in English (or bilingually) and accepted by embassies and overseas authorities.

How much does a notary public cost in Bangkok?

NYC Legal's notary service fee starts at THB 1,500 per document and typically ranges THB 1,500–8,000 depending on document type, number of pages, language pair and whether MFA legalization or embassy authentication is required. Volume and corporate pricing is available. Get an exact quote via LINE @NYCLI.

Do you provide notary services in English?

Yes. All notarial certificates and acknowledgements are issued in English (or bilingual Thai/English). Our attorneys are registered with the Lawyers Council of Thailand and experienced with US, UK, Australian, Canadian and EU document requirements.

I need my document used abroad. What is the full process?

Four steps: (1) Notarization by a Notarial Services Attorney; (2) certified English translation if required; (3) legalization by the Thai Ministry of Foreign Affairs (Department of Consular Affairs); (4) authentication by the destination country's embassy if it is not a Hague Apostille state. NYC Legal handles all four end-to-end.

Can you come to me, or do I have to visit the office?

Both. For certified copies and translations you can send documents by LINE or post. For signature notarization you must sign in front of the attorney — we offer in-office appointments, mobile signing at your home or office anywhere in Thailand, and remote e-notarization for eligible documents.

How long does notarization take?

In-office notarization takes 30–60 minutes. Certified translation adds 1–2 business days, MFA legalization 1–3 business days, and embassy authentication 3–10 business days. End-to-end turnaround for documents used abroad is typically 5–15 business days; same-day notarization is available for urgent cases.

Which languages do you serve besides English?

Beyond Thai and English we publish dedicated notary pages in Chinese, Japanese, Korean, German, French and Russian, and serve clients in many more languages on request. See the language links below.

The 4-step process for documents used abroad

1. Notarization
A Notarial Services Attorney certifies your signature, copy or affidavit and affixes the notarial seal — in English or bilingual format.
2. Certified translation
If your destination requires it, we produce a certified translation accepted by the MFA and foreign authorities (1–2 business days).
3. MFA legalization
The Thai Ministry of Foreign Affairs (Department of Consular Affairs) legalizes the document so it is valid overseas (1–3 business days).
4. Embassy authentication
For non-Hague-Apostille countries, the destination embassy in Bangkok authenticates the document (3–10 business days).
