Do I need a NAATI translator for Thai tax returns (PND 90/91) to prove my Thai partner's income? — 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 how certified translation by a NAATI-certified translator works. 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.
