A NAATI certified translation is produced by a translator credentialed by Australia's National Accreditation Authority for Translators and Interpreters. It is what Australian and New Zealand bodies — the Department of Home Affairs, universities and professional assessors — expect for non-English documents.

Risk flagged: NAATI credentials expire. A translation stamped after the practitioner's expiry date will be rejected.
Risk flagged: Never self-translate, however strong your English: Australian authorities treat the applicant as an interested party.

Cautions from real casework
• NAATI credentials expire. A translation stamped after the practitioner's expiry date will be rejected.
• Never self-translate, however strong your English: Australian authorities treat the applicant as an interested party.
• Buddhist-era dates must be converted correctly; a one-year discrepancy is enough to have the file returned.
• Every document must spell your name exactly as in your passport. If the spelling differs, attach the name-change certificate or a transliteration note.
• Torn, corrected or copy-of-a-copy originals are commonly rejected at the legalisation stage — request a freshly issued copy from the issuing authority first.
• Some documents carry a validity window (often 3–6 months from issue) set by the receiving authority. Check it before starting the chain.
Consultant tips
• Always send the passport copy along with the batch so the name spelling is consistent from the start.
• Scan every original to a 300 dpi colour PDF before sending it out, in case you must refile or the destination asks for a soft copy.
• Always prepare two sets — one to submit, one to keep. Many authorities retain the submitted originals.
• If the documents will be used in more than one country, say so up front: the number of sets and the attestation format differ by destination.
• Leave at least two weeks' buffer before your real deadline: Thai public holidays and embassy holidays do not coincide.
The full working process
Typically 1–3 business days per set · same-day handling depends on page volume · add 3–5 business days if MFA legalisation follows
1. Collect and verify originals
Scan every page in colour and make sure stamps and signatures are legible: a NAATI translation must render every element that appears on the page.
2. Confirm the language pair and direction
NAATI credentials are directional (for example Thai into English only). The translator must hold the credential for the direction you need.
3. Translate and double-check
Verify passport-matching name spelling, document numbers, Buddhist-to-Gregorian date conversion and consistent renderings of Thai agency names across the whole set.
4. Apply the NAATI stamp and certification
Each translated page must carry the stamp, practitioner number, credential expiry, signature and date.
5. Add legalisation if the destination requires it
Some uses — registering a marriage in Australia, or presenting Thai documents to a third body — additionally require MFA legalisation.
6. Deliver soft copy and hard copy
Most Australian bodies accept a PDF scanned from the stamped original, though some request the hard copy by post.
Authorities involved: NAATI (Australia) · Department of Consular Affairs, Thai MFA (when legalisation follows)
Frequently asked questions
What is NAATI Translation and what is it used for?
NAATI translation applies to Thai documents filed in Australia or New Zealand. The translator must hold a current NAATI credential, and the translation must carry the stamp, signature, date and practitioner number on the page. Turnaround is typically one to three business days per set; if MFA legalisation is also needed, allow at least two weeks overall.
How many steps does NAATI Translation involve?
The standard chain has 6 steps, beginning with "Collect and verify originals" and ending with "Deliver soft copy and hard copy".
What is the first step of NAATI Translation?
Collect and verify originals — Scan every page in colour and make sure stamps and signatures are legible: a NAATI translation must render every element that appears on the page.
How long does NAATI Translation take?
Typically 1–3 business days per set · same-day handling depends on page volume · add 3–5 business days if MFA legalisation follows
Which documents do I need for NAATI Translation?
The baseline set is: Passport bio-data page · Thai national ID card · Birth certificate / house registration · Marriage, divorce or single-status certificate · Name-change certificate, if any and others depending on the case. The receiving authority may ask for more depending on the purpose.
Which authority certifies NAATI Translation?
NAATI (Australia) · Department of Consular Affairs, Thai MFA (when legalisation follows)
Who typically needs NAATI Translation?
Applicants for any Australian visa stream (partner, student, work, visitor) · Students applying to Australian and New Zealand institutions · Professionals lodging skills assessments (nursing, engineering, teaching) · Citizenship and PR applicants attaching Thai civil-registration records
What most often causes NAATI Translation to be rejected?
NAATI credentials expire. A translation stamped after the practitioner's expiry date will be rejected.
Do you need originals or are copies enough?
Scans are enough for the initial review, but many certification steps require originals or freshly issued certified copies. We tell you which at the first assessment.
Do documents expire?
Civil registration documents and certificates are often accepted only within 3–6 months of issue. Check the destination's rule before starting so the chain does not have to be repeated.
Can I use the service from another province or from overseas?
Yes. Send documents by post or courier and we return them to any address, with status updates at each stage. No in-person visit is required.
What if the destination requires a specific format?
Tell us the authority and purpose up front. We shape the translation layout and the order of certifications to that requirement instead of producing a generic set and reworking it later.
Which NAATI Translation package should I choose?
Essential if your documents are ready and you only want a pre-submission check · Complete if you want the whole chain handled · Advisory if the case is complex or has been refused before.
Why use an advisor rather than doing it myself?
Our team has advised on cross-border documents for more than 15 years. We do not just file paperwork: we first check that your document route actually matches what the destination will accept. If you would rather not learn by trial and error, send the documents to us for a review first.
Any tip that makes the case move faster?
Always send the passport copy along with the batch so the name spelling is consistent from the start.
How do I get an initial assessment?
Send images of the documents plus the destination country and authority by LINE or email. You get back the real sequence of steps and a realistic timeframe.
More than a filing agency
With 15+ years of casework, we explain why each step exists, where your documents will be used and what the destination authority checks — so you decide with full information, not just pay and wait.
