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

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.
What is a NAATI-certified translation?
A translation produced by a translator certified by NAATI, Australia's National Accreditation Authority for Translators and Interpreters. Australian government bodies treat it as the standard for foreign-language documents filed with an application.

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 rejected — NAATI

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

  • Names must match the passport used for filing; where the original differs, the translator's note must explain the discrepancy.
  • 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.

Common causes of rejection

  • Supplying cropped or blurred source images, which forces an illegibility note and a resubmission request.
  • A translation prepared before, but signed after, the practitioner's certification expiry date.

The lowest-risk approach is to confirm whether the receiving authority wants a digital or printed set, and to prepare complete, sharp images of every page before work starts. Send the details to our team by phone, LINE, or email for review.

Practitioner guidance — NAATI certified translation

Competent authority: NAATI — National Accreditation Authority for Translators and Interpreters, Australia

Practitioner guidance

  • Documents filed with Australian authorities must be translated by a NAATI-certified translator, with the NAATI stamp and CPN visible on the translation.
  • NAATI translations do not require MFA or embassy legalisation unless the receiving body specifically asks for it.
  • Always submit the translation together with the source copy the translator worked from; assessors compare both.
  • Verify that the CPN printed on the translation is searchable in NAATI's verification system.
  • Assemble the full document set before ordering so names, dates and terminology stay consistent.

Pitfalls — why documents get rejected

  • An incomplete relationship-evidence set, triggering a request for further information.
  • Assuming NAATI certifies visa outcomes — it certifies translator credentials only.
  • Filing an MFA-certified translation with an Australian authority that requires NAATI.
  • A translation without a NAATI stamp or without a verifiable CPN.
  • Submitting the translation without the source copy it references.
