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.

Which Australian bodies require it?

Most commonly the Department of Home Affairs, state road authorities such as VicRoads, universities and colleges, state registries of births, deaths and marriages, and professional skills-assessment bodies. Requirements vary by body.

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.

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.

A NAATI translation differs from a general certified translation because the practitioner's certification status must be verifiable as at the date of signature. Certification carries an expiry date, and receiving bodies can check it retrospectively.

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

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.

Practitioner guidance — NAATI certified translation

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

Practitioner guidance

Third-country, non-English documents can also be translated into English under the NAATI system without routing through the issuing country.
Turnaround is approximately 5–7 working days depending on page count and language pair — confirm before fixing a lodgement date.
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.

Pitfalls — why documents get rejected

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.
Name spelling differing from the passport used in the visa application.
Reusing an old translation whose source document was later amended or reissued.

In-depth questions and answers — NAATI certified translation

Answers follow the competent authority's published requirements, not marketing copy.

What if our NAATI certified translation case has unusual conditions?

For edge cases — mismatched names across documents, foreign-issued records, or a tight deadline — have the set reviewed first, then reconfirm the conditions with NAATI — National Accreditation Authority for Translators and Interpreters, Australia. Ask our staff by phone, LINE or email for scope and timing (we do not publish fees on the page because they depend on the document type and destination). This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How long does NAATI certified translation take?

Turnaround is not fixed: it depends on the queue and rules of NAATI — National Accreditation Authority for Translators and Interpreters, Australia, the document type, and the receiving office abroad. For that reason we do not publish a fixed figure. Plan a buffer before your real deadline and ask our staff by phone, LINE or email for the current queue before booking travel. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Does the result of NAATI certified translation expire?

Validity is set by the receiving office, not by the service provider. Many offices accept only recently issued documents, so confirm the destination's window first and only then start the process with NAATI — National Accreditation Authority for Translators and Interpreters, Australia, to avoid the document expiring while it waits in the queue. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Must the applicant appear in person for NAATI certified translation, or can it be delegated?

Some steps require the document owner to sign or appear; others accept a power of attorney. It depends on the rules of NAATI — National Accreditation Authority for Translators and Interpreters, Australia and on the document type, so confirm before booking an appointment rather than travelling and being turned away. Our staff can clarify by phone, LINE or email. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Why is no price shown for NAATI certified translation on this page?

Scope varies widely per case — page count, languages, number of certification rounds, and the official fees charged by NAATI — National Accreditation Authority for Translators and Interpreters, Australia under its published schedule. A single headline figure would be misleading, so we quote against the actual documents. Send the details by phone, LINE or email for an assessment matched to your case. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

How should documents for NAATI certified translation be prepared to pass on the first submission?

Documents filed with Australian authorities must be translated by a NAATI-certified translator, with the NAATI stamp and CPN visible on the translation. The competent authority is NAATI — National Accreditation Authority for Translators and Interpreters, Australia. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

What should be checked first before filing for NAATI certified translation?

NAATI translations do not require MFA or embassy legalisation unless the receiving body specifically asks for it. The competent authority is NAATI — National Accreditation Authority for Translators and Interpreters, Australia. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Which practices reduce correction rounds in NAATI certified translation?

Always submit the translation together with the source copy the translator worked from; assessors compare both. The competent authority is NAATI — National Accreditation Authority for Translators and Interpreters, Australia. This is general guidance; requirements and processing times change — verify with the competent authority before filing.

Your case may have specific conditions — ask our staff directly.
