Is a NAATI translation of a Thai birth certificate valid forever, or does it eventually expire?

Is a NAATI translation of a Thai birth certificate valid forever, or does it eventually expire? — Thai Notary Law works with NAATI-certified practitioners; every page carries the translator stamp and CPN so the file is accepted as submitted. Check that names match the passport spelling before lodgement, and confirm current requirements with the receiving authority.

This page covers the document types Australian authorities most often require in translation. A Thai-language document intended for an Australian authority is translated into English by a translator certified by NAATI in the Thai→English direction, then issued with a certification statement and stamp showing the translator's CPN and certification expiry. The original (or a certified copy) is submitted together with the translation.
