Durations are estimates and depend on the responsible authority's queue. Always confirm current requirements with the receiving body before filing.

Additional frequently asked questions

Does a NAATI translation need further legalisation?
Australian bodies generally accept the certified translator's stamp without embassy involvement, though other legal proceedings may call for additional certification case by case.
Which languages and documents are covered?
Thai–English is the most requested pair, alongside other pairs with certified practitioners. Typical documents are birth certificates, house registration, marriage certificates, driving licences, transcripts and police clearance certificates. Scope and requirements are confirmed case by case by phone, LINE or email.
Are original documents required?
Clear scans of every page — including seals and reverse-side text — are normally sufficient. If the receiving body asks to sight originals, the applicant must bring them on the filing day.
What file format is delivered?
Usually a PDF bearing the certified translator's stamp and signature with the practitioner number and certification validity details that NAATI requires to be displayed.
What if the name spelling differs from the passport?
The passport spelling governs. Where the source document spells it differently, the translator adds an explanatory note so the reviewing officer can link the records.
Does the translation expire?
The translation itself does not expire, but translator certification runs in renewal cycles and the receiving body may ask for a freshly issued source document, so confirm the rules before filing.

How this connects to the next step

Australian agencies accept only NAATI translations, yet originals such as powers of attorney still need Thai attorney notarial certification first; partner and skilled visa files usually run in parallel with a Thai police clearance certificate.

In depth: the real requirements and why documents get rejectedNAATI

Written from the competent authority's published rules, not marketing copy.

The documents most often handled under NAATI requirements are house registrations, birth certificates, marriage certificates, name-change records, academic transcripts, and police clearance certificates — each with its own points of scrutiny.

Conditions you actually have to clear

  • The translation must display the NAATI stamp with the practitioner number and a certification expiry that is still current on the signature date.
  • The language pair and direction must match the direction in which the practitioner is certified.
  • Every page and every element of the original must be covered, including pages that carry only a seal.

Common causes of rejection

  • A translation prepared before, but signed after, the practitioner's certification expiry date.
  • Translating only the pages containing text and omitting seal-only or numbered blank pages.

Where a visa or registration deadline applies, allow time for the possibility that the assessor requests additional documents, rather than budgeting only for translation time.
