Legalising Thai Documents for Australia (2026)

Obtain a certified extract from the issuing authority (district office, school, court or DBD) → Translate into the language the destination requires, with the translator named and signing a statement of accuracy → File for legalisation of the translation and/or the official signature at the Legalization Division, Department of Consular Affairs → File directly with the Australian authority, or add Australian embassy attestation when the receiving body requires it

Yes. Australia is a party to the HCCH 1961 Apostille Convention, but Thailand is not yet bound until 28 February 2027, so Thai documents still need MFA legalisation plus attestation at the Australia mission in Thailand.

Once the Convention enters into force for Thailand on 28 February 2027, Thai public documents used in this country will need a single Apostille from the Department of Consular Affairs instead of embassy attestation, subject to any extra requirements the receiving body sets on translation format or document age.

The Department of Home Affairs generally accepts NAATI translations without legalisation, but state Births Deaths and Marriages registries and family courts often want the underlying Thai document legalised by the MFA.

Using a translator without a current NAATI number · Translating a photocopy rather than a certified extract · Legalising before translating and having to redo the file

Certified translation 1–2 working days; MFA legalisation 2–3 working days (THB 200 per stamp) or same-day express when filed before 11:30 (THB 400 per stamp); the destination embassy queue is separate and typically 3–10 working days.

The Legalization Division's practice is to start from a fresh certified extract issued by the source authority, translate that, and then file the translation with the original. Translating an old photocopy is the most common cause of rework.

Yes. We work from a power of attorney bearing a THB 10 duty stamp together with certified copies of the grantor's and agent's ID. If you are outside Thailand, a Thai embassy or consulate must witness your signature first.
