Q1065. Is a NAATI translation of a Thai birth certificate valid forever, or does it eventually expire?
Answered by NAATI Certified Practitioner · NYC Visa & Translation
A NAATI-certified translation of a Thai birth certificate generally has no automatic expiry date, but the receiving authority decides whether it remains suitable. A translator's credential renewal date should not be confused with an expiry date for every translation they previously issued. You may need a replacement if the source certificate is corrected, the translation contains an error, or names and identity details require clarification. Submit any relevant name-change documents rather than altering the birth certificate translation to match a later name. Keep the original Thai document and its translation together. Confirm current evidentiary requirements with the Department of Home Affairs or other receiving authority before reusing an older translation.
