Why must I use a NAATI translator for Partner Visa?

The Department of Home Affairs only accepts translations by NAATI-certified translators for documents submitted from outside Australia. MoJ-only translations are rejected.

Can I use my Thai marriage certificate for AU citizenship later?

Yes. The MFA-legalized Kor Ror 3 with NAATI English translation is accepted by Department of Home Affairs for all subsequent visa stages and citizenship by descent for children.

Is NAATI translation required for an Australian partner visa?

Yes. DHA requires NAATI-certified English translations for Thai marriage certificates, household registration, ID cards, and any supporting evidence in Thai. Non-NAATI translations are routinely rejected.

Can you provide NAATI translation online?

Yes. We deliver NAATI-certified PDFs with digital signature and QR verification within 24-48 hours, accepted by DHA, universities and employers.

Do I need Apostille or MFA legalization for Australia?

Both work. Since Thailand joined Apostille in Dec 2024, a single Thai Apostille is sufficient for Australia. MFA legalization remains valid as a fallback.

AI Quick Answer

How does a Thai citizen marry a Australia national in Thailand?

The Australia spouse obtains a Certificate of No Impediment (or equivalent affidavit) from the Australia Embassy in Bangkok, has it translated into Thai and legalized by the Thai Ministry of Foreign Affairs, then registers the marriage at any Thai amphur with two witnesses. After registration, request the English Kor Ror 3 and re-legalize it via MFA for use in Australia. Total time: 7-14 days.
