NAATI credentialled translator preparing certified Thai–English documents

How to verify and choose a NAATI translator

Quick answer

The most direct check is to search the practitioner name and number in NAATI’s own Online Directory and match it against the stamp on the translation. For documents translated outside Australia, the Department of Home Affairs requires the translation to show the translator’s full name, address, contact number and qualifications or experience in English; translations produced in Australia must come from a NAATI-certified translator.

The sequence published by the authorities

  1. Confirm with the receiving authority which document, which language, and which layers of certification it requires.
  2. Collect originals certified by the issuing office, including every page that carries an entry.
  3. Reconcile names, dates of birth and document numbers across all documents before translation starts.
  4. Translate and have the responsible person sign the certification in the format the destination requires.
  5. File in the order published by the authority and keep each filing receipt so status can be traced.

Validity of the NAATI stamp

The NAATI stamp shows the practitioner’s credential expiry date, not an expiry of the translation itself; some receiving agencies still ask for a fresh translation when the source document has changed.
