Is NAATI recognised by Thai government offices?
NAATI is an Australian credential. Thai offices look for a certified translation in their own accepted format, so a NAATI translation may need to be recertified locally for Thai use.
NAATI translation vs Thai certified translation
NAATI is the Australian national credentialing authority for translators; a NAATI-certified translation carries the practitioner's stamp and number and is the default expectation of Australian government agencies such as the Department of Home Affairs. A Thai certified translation, even with lawyer certification and MFA legalisation, follows the Thai chain and is aimed at Thai and third-country authorities. Neither is universally superior — the correct choice is dictated by the authority that will read the document.
Point-by-point comparison
| NAATI-certified translation | Thai certified translation | |
|---|---|---|
| Credentialing body | NAATI, Australia (naati.com.au) | No Thai register; translator or agency self-certifies |
| Visible marking | Practitioner stamp with certification number and expiry | Certification statement, translator signature, agency seal |
| Primary audience | Australian government, universities, courts | Thai authorities, embassies in Bangkok, third countries |
| Legalisation needed | Usually not for Australian domestic use | Often followed by lawyer certification and MFA legalisation |
| Where it is produced | By a credentialed practitioner, wherever they are based | In Thailand, matched to the Thai chain of stamps |
| Typical turnaround | Depends on practitioner availability for the language pair | Same day to a few working days plus legalisation time |
NAATI-certified translation — choose this when
- You are filing with an Australian government department or university
- The written requirement names NAATI explicitly
- The document will be used inside Australia rather than presented in Thailand
Thai certified translation — choose this when
- The recipient is a Thai authority, an embassy in Bangkok or a non-Australian country
- The chain continues through the MFA and a destination embassy
- You need a language pair with no available NAATI practitioner
Frequently asked questions
Can one document carry both certifications?
Yes — some clients need a NAATI version for Australia and a separately certified Thai version for local filing. They are prepared as two deliverables from the same source document.
Does the Department of Home Affairs always require NAATI?
Its published guidance expects translations by appropriately credentialed translators, and NAATI is the standard credential in Australia. Always follow the wording of the specific application guidance you are filing under.
Do NAATI translations need MFA legalisation?
For Australian domestic use, generally no. If the same document is then presented to a Thai authority or a third-country embassy, the Thai chain may be requested.
Which is faster?
Neither route is inherently faster; availability of a practitioner for your language pair and the MFA queue are the usual bottlenecks. We give a realistic range once we know the language and destination.
What if I am not sure which the authority wants?
Ask them in writing and send us the reply. Choosing on a guess is the main reason documents are translated twice.
Send us a photo of the document plus the written requirement from the receiving authority, and we will map the exact chain — translation, lawyer certification, MFA, embassy — before you pay for anything. Call 094-895-8999 or LINE @Thainotary.
Information current as of August 2026. Requirements change — confirm the exact certification format with the authority that will receive the document before you file. Acceptance is at their discretion.
