What changed in 2024

On 2 January 2024 Thailand acceded to the Hague Convention Abolishing the Requirement of Legalization for Foreign Public Documents (the Apostille Convention). The convention entered into force for Thailand on 14 July 2024.

Before this, every Thai document destined for use abroad required two layers of authentication: first the MFA's Department of Consular Affairs, then the foreign embassy in Bangkok. The new Apostille collapses this into a single MFA stamp accepted in all 125+ member states.

Which documents qualify

Apostille covers Thai public documents and notarial acts: birth/marriage/death certificates, criminal records, academic transcripts, court judgments, and notarised translations or POAs.

Birth, marriage, death certificates (from district office)
Police clearance (Royal Thai Police)
Educational certificates (after Ministry of Education endorsement)
Notarised translations from a Notarial Services Attorney
Court documents and corporate registrations (DBD)

The new step-by-step process

If your Thai document is destined for a Hague country, the workflow is now: 1) Translate (if needed) by a sworn translator; 2) Notarise the translation with a Notarial Services Attorney; 3) Submit to MFA Chaeng Wattana for Apostille; 4) Use abroad.

Turnaround is 2 business days for normal service (฿200 + ฿400 Apostille fee per document) or same-day for expedited (฿800). NYC handles end-to-end for ฿1,500–3,000 per document including translation.

Non-Hague countries still need legalization

If your destination country is NOT a Hague member (UAE, Saudi Arabia, China, Vietnam, Malaysia, Indonesia, Cambodia, Laos, Myanmar), you still need the old dual-legalization workflow: MFA legalization + destination embassy stamp in Bangkok.

Frequently Asked Questions

Is the Apostille recognised in the US and UK?

Yes. Both the United States (since 1981) and the United Kingdom (since 1965) are full members of the Hague Apostille Convention. A Thai MFA Apostille is accepted without further legalisation for US/UK visa lodgement, USCIS petitions, UK Home Office submissions, marriage registration, immigration, and court filings in any state or jurisdiction.

Do I still need a translation?

Yes. The Apostille only certifies the origin of the issuing authority and the seal — it does not translate or validate the document's language content. You still need a sworn Thai-to-English (or destination language) translation. That translation must itself be notarised by a Thai notarial attorney before the Apostille stamp is applied to the bundle.

How long does the Apostille take?

Standard service at the Thai MFA office in Chaeng Wattana takes 2 business days for walk-in submissions. Same-day express costs ฿800 per document. NYC's full-service end-to-end handling — pickup, sworn translation, notarisation, MFA queue, and courier return to your address — runs 3–5 business days door-to-door, with same-day express available on request.

Can NYC handle this for me if I'm abroad?

Yes. We routinely serve overseas clients. Email us scans of your documents and we prepare the sworn Thai translations, courier originals from your contact in Thailand (or from any government office on your behalf), complete the MFA Apostille step, and ship the legalised set worldwide via DHL Express or FedEx with tracking.
