If the translator's credential expires after my translation is done, is it still valid?
In principle the translation reflects the practitioner's status on the signing date, so if the credential was current then it was produced by a certified practitioner. Some authorities, however, ask for translations produced within a recent window.
In-depth Answer
NAATI runs a three-year recertification cycle in which practitioners evidence work practice and professional development to keep their credential.
The expiry date is printed on the stamp precisely so a recipient can confirm the signing date fell inside a valid period.
Once that date passes, the earlier translation is not retrospectively void, because what was certified was the accuracy of the translation at that time.
What changes is ease of verification: an officer searching the register later may not see a current status and may query it.
The safe practice is to keep a copy that clearly shows the signing date, and where the receiving body sets its own freshness rule — documents issued within a set recent period, for example — simply commission a fresh translation rather than argue the point.
