Apostille in Thailand 2026: Status, Alternatives & Timeline
Thailand has not yet joined the Apostille Convention. Here is what foreigners and Thais need to do for international document recognition in 2026.
For documents issued in Thailand to be accepted abroad, most countries require legalization. As of 2026, Thailand has signed but not yet ratified the Hague Apostille Convention, so the two-step legalization process remains.
Step 1 — Translation & notarization
Most foreign-language documents must first be translated by a certified translator and notarized by a licensed Notarial Services Attorney.
Step 2 — MFA Consular Department
The Thai MFA's Consular Division at Chaeng Watthana certifies the signature and seal. See our MFA legalization service.
Step 3 — Destination embassy
Submit the MFA-certified document to the destination country's embassy in Bangkok. Each embassy has its own fees and processing time. Browse our embassy directory.
Country-by-country requirements
Some countries (e.g., USA, Germany, France) require additional steps such as certified translations into the local language. Check our visa & country guide for the latest requirements.
Frequently asked questions
Does Thailand issue Apostilles?
Not yet. Thailand has signed but not ratified the 1961 Hague Apostille Convention as of June 2026. Documents need full consular legalization.
What is the alternative?
Two-step legalization: (1) certification by Thailand's Ministry of Foreign Affairs (MFA), then (2) legalization at the destination country's embassy in Bangkok.
How long does it take?
MFA standard service: 3 working days. Embassy legalization varies (1–14 days). ILC offers express MFA in 1 working day.
Can ILC handle the whole process?
Yes — translation, notarization, MFA, and embassy legalization end-to-end.

Common reasons a bundle is rejected
- Countries outside the Apostille Convention still need a further endorsement at the destination embassy.
- Translations that use an unofficial English name for a Thai agency are sent back for correction.
- Spell every name exactly as it appears in the passport, across every document in the same bundle.
