Legalizing Foreign Documents (MFA Process)
How to legalize foreign documents for use in Thailand through apostille, translation, and Ministry of Foreign Affairs (MFA) endorsement.
Last reviewed: 2026-06-01 · by Anglo Siam Law Editorial Team · How we research this topic
TL;DR
Document legalisation for foreign documents intended for use in Thailand is administered by the Ministry of Foreign Affairs (MFA) Consular Affairs Department at Chaengwattana, Bangkok. Thailand is not party to the 1961 Hague Apostille Convention; the legalisation chain is therefore: notarisation in the country of origin → home-country foreign ministry authentication → Thai embassy / consulate legalisation → MFA Chaengwattana certification on arrival in Thailand.
Overview
How to legalize foreign documents for use in Thailand through apostille, translation, and Ministry of Foreign Affairs (MFA) endorsement. This guide explains what to expect, your rights, and the steps you should take to protect yourself in this situation.
Immediate Steps to Take
Identify exactly which documents need legalization and for which Thai government office
Determine if your country is in the Hague Apostille Convention (UK, USA, most EU: yes)
Obtain an apostille from the country that issued the document (or embassy legalization for non-Hague countries)
Have the document translated by an MFA-registered translator in Thailand
Submit original + apostille + Thai translation to MFA Consular Affairs Division in Bangkok
Pay THB 200 per document and collect endorsed documents (usually same day)
Legal Considerations
Important legal points to understand about this situation:
Documents without MFA endorsement are not legally valid for Thai government purposes
Only MFA-registered translators' translations are accepted — check the MFA website for the current list
The apostille must be from the country that issued the document, not your country of citizenship
Some documents have validity periods — police clearance certificates typically expire after 6 months
For court submissions, additional notarization may be required on top of MFA endorsement
Non-Hague Convention countries (China, Vietnam, India) must use Thai embassy legalization instead of apostille
The MFA Consular Division is in Bangkok on Sri Ayudhya Road — use online appointments to avoid queues
The entire process from scratch (apostille + translation + MFA) takes 2-6 weeks
Key Statutes
| Statute | Reference | Note |
|---|---|---|
| Civil Registration Act | B.E. 2534 (1991) | Document acceptance standards for civil status records |
| Notarial Services Act | B.E. 2546 (2003) | Thai notarial-services framework |
| Ministry of Foreign Affairs Notification on Legalisation | Current MFA procedures | Consular legalisation chain |
Common Mistakes to Avoid
- Expecting an Apostille to be accepted — Thailand is not party to the 1961 Hague Apostille Convention.
- Submitting untranslated documents — Thai-language certified translation is required for most uses.
- Skipping the home-country foreign ministry step — Thai embassy will refuse legalisation without it.
- Trying to use Thai-notarial-attorney legalisation for documents going abroad — Thai notary attorneys can only certify for foreign use, not the reverse.
Embassy Assistance
What Your Embassy Can Do
Your home country embassy/consulate may need to issue certain documents (e.g., Affirmation of Freedom to Marry). Some embassies also provide document certification. The Thai MFA handles the final endorsement step.
Frequently Asked Questions

Standard service: 2-3 business days. Express service available at higher fee. Walk-in is possible; appointments recommended for large batches.
Is digital document legalisation available?
Some categories of documents have moved to e-Government Document Authentication; verify current MFA notification for your specific document type.
