What is the official format and wording required for a Power of Attorney (POA) for MFA document legalization? — The Legalisation Division, Department of Consular Affairs, Ministry of Foreign Affairs (Chaeng Watthana, Bangkok) is the authority that legalises Thai documents. Thai Notary Law prepares, translates, lodges and tracks the file end to end; approval remains at the discretion of the authority.
Official fees at the Department of Consular Affairs are charged per document at the rate published on consular.go.th, separately from translation and handling. Documents must be originals or copies certified by the issuing Thai authority, and every translation must match the spelling shown in the applicant’s passport.
| Decision-maker | Legalisation Division, Department of Consular Affairs, MFA Thailand |
|---|---|
| Direction | Thai document → used abroad |
| What is certified | The signature and seal of the issuing officer, and the conformity of the translation — not the truth of the content |
| Translation | Required; must match the source line-by-line including seals and reverse-side text |
| Apostille | Available for destinations that accept it; otherwise the legacy embassy chain applies |
| Official fee | Per document, at the rate published by the Department of Consular Affairs — verify on consular.go.th |
| Processing time | Varies by service track and workload — confirm at filing; excludes peak periods |
What the Department of Consular Affairs certifies is the authenticity of the issuing officer's signature and seal, plus the conformity of the translation with the source — not the truth of the content. That is why the source must always be issued or certified by a government office, and why some destination countries still require their own embassy in Bangkok to attest the document afterwards.

Documents issued in Thailand still pass through the same division; an English-language original may still need a Thai translation or a certified transcription depending on the issuing office.
No provider can influence the ministry's queue or its decision. What an agency does is prepare a translation that meets the formatting rules the first time, which is what avoids the refile loop that costs most applicants their extra days.
Only if the destination is a party to the Apostille Convention and accepts it for your document type. For non-party destinations the legacy chain — MFA legalisation followed by that country's embassy attestation — is still required.
A copy is accepted only when the issuing authority itself certified it as a true copy. Self-made photocopies are refused at the counter.
The stamp itself does not expire, but many receiving authorities require the underlying civil registry extract to have been issued within the last 3–6 months. Check the receiving body's rule before filing.
Information current as of 2026-07-21. Requirements differ between receiving authorities — always confirm with the body that will receive your documents.
