Certified Translation for Submission to the Department of Consular Affairs

Translation of Thai civil-registry documents into English (or the reverse) in the format the Legalisation Division of the Department of Consular Affairs will accept. Accuracy of name spelling, document numbers and table layout decides the outcome — a single mismatch usually means the file is returned and the queue starts again.

Advice from our team
- Send your passport scan before translation starts so spellings are locked across every document
- File all documents in one batch to reduce trips and the risk of a page going astray
- Ask the receiving authority to state in writing whether it wants a certified translation or a legalised document
- Keep colour scans of every certification layer in case the destination asks for an advance check
Things to watch out for
- Omitting a seal or a footnote from the translation is the most common reason a file is returned
- Government fees and service cycles change — verify current details at consular.mfa.go.th before filing
- Never write on or amend a document that already carries a certification stamp
- Certification confirms the translation matches the original, not that the underlying facts are correct
Frequently asked questions
Is the original document required?
Normally yes — an original or a certified copy from the issuing authority. Plain photocopies are usually not considered.
Can I translate it myself?
You may, but the format and every line must be acceptable to the reviewer. Having an experienced translator check the file before filing significantly reduces rejections.
What are the fees?
Legalisation fees are set by the authority and change from time to time. Please check the latest rates on the Department of Consular Affairs website.
What if the destination is not English-speaking?
Some countries accept English; others require their own official language. Confirm with the receiving authority, then translate accordingly.
