Getting an 'Apostille' in Thailand: Legalisation Workflow

TL;DR

Thailand is not party to the Hague Apostille Convention. Document authentication for use abroad goes via the Ministry of Foreign Affairs Department of Consular Affairs (commonly called "legalisation" rather than apostille) plus the destination-country embassy in Bangkok. The standard chain is: original Thai document → certified translation → MFA legalisation → destination embassy stamp.

Standard Workflow

1. Obtain the original Thai document (e.g., marriage certificate, birth certificate, criminal record check).
2. Translation into the destination language by a recognised translator.
3. MFA Department of Consular Affairs (Chaengwattana) authentication of translation.
4. Destination-country embassy further authentication / legalisation as required.

Document Types Commonly Legalised

MFA Service Channels

• Walk-in at Department of Consular Affairs (Chaengwattana).
• Postal service ("e-legalisation" with prepaid return).
• Express service (next-day, surcharge).
• Standard fee: THB 200-400 per document.

Destination-Country Embassy Step

• Some embassies waive embassy-level legalisation if MFA seal is present and the destination country trusts Thai MFA — varies by country.
• US, UK, Australia, etc. — check the current embassy guidance.
• Some destination countries (e.g., China for civil-registration use) require their embassy stamp.

Common Mistakes

• Believing "apostille" exists in Thailand — it does not.
• Translating before getting original certification updated.
• Skipping the destination-embassy step where required.
• Using non-recognised translators — MFA rejects.

FAQs

1. Is Thailand planning to join Apostille?

Periodic policy discussion; current position is non-party.

2. Same-day legalisation possible?

Express service offers next-day; same-day rare.
