MFA Legalization and Apostille for Thai Documents — Complete Guide
Short answer first
Thai documents used abroad are legalized by the Department of Consular Affairs, Ministry of Foreign Affairs, and then by the destination country's embassy where required. The standard consular fee is THB 200 per document, or THB 400 for express service. Thailand's accession to the Apostille Convention takes effect on 28 February 2027; until then the MFA plus embassy chain remains in force.
Overall timeline: 1–3 weeks depending on the destination embassy
Documents to prepare
| Item | Detail | Status |

| Certified translation | Usually Thai to English, prepared in the format the MFA accepts. | Required |
| Passport or ID of the document holder | Also required for the authorised representative submitting on your behalf. | Required |
| Power of attorney | Needed when we submit for you. | If available |

Pitfalls and how to avoid them
Advice from real cases
- Legalize spare copies while the file is open — repeating the chain later costs far more time.
- Check whether the destination accepts English or requires the local language.
- Embassy timelines vary widely; build in buffer before travel dates.
