The rule that decides your route

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.

Step-by-step process

  1. Once stamped, take the document for onward attestation at the destination country embassy in Bangkok when that country requires it
  2. Obtain a freshly certified original or true copy from the issuing Thai authority (district office, university, court)
  3. Prepare the translation into English or the destination language, spelling names exactly as in the passport
  4. Proof the translation line-by-line against the source, including seals, signatures and reverse-side text
  5. File the legalisation request with the Legalisation Division, Department of Consular Affairs, together with the source document
  6. If the officer raises a discrepancy, correct the translation and refile as instructed

What to prepare

  • A power of attorney with ID copies if someone files on your behalf
  • Any written requirement from the receiving authority specifying format or language
  • The original, or a true copy certified by the issuing Thai authority (self-made photocopies are not accepted)
  • A translation matching the source line-by-line, including seals and signatures
  • Thai ID card and/or passport of the document holder to confirm name spelling

Why documents get sent back

  • Submitting a self-made photocopy instead of a copy certified by the issuing authority
  • Name spelling in the translation not matching the passport, or inconsistent transliteration across records
  • Incomplete translation — seals, signatures or reverse-side text omitted
  • Assuming MFA legalisation is the end of the chain when the destination country still requires its own embassy attestation
  • Using civil registry extracts older than the receiving authority allows (often 3–6 months)

Related questions

Is an Apostille always the better route?

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.

Can I file with a copy instead of the original?

A copy is accepted only when the issuing authority itself certified it as a true copy. Self-made photocopies are refused at the counter.

How long does the certification stay valid?

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.

Who certifies a document already in English?

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.

Does an agency speed up the queue at the ministry?

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.
