Certified Translation of Thai Documents for Australia

NAATI-certified translator Registry to verify: NAATI (National Accreditation Authority for Translators and Interpreters).

Australian authorities such as the Department of Home Affairs generally accept a NAATI translation without further legalisation, though some state registries also ask for the underlying Thai document to be legalised.

NAATI translation 2–4 working days; MFA legalisation adds 2–3 working days if required. This excludes the receiving authority's own queue.

Australia is a Hague party, but an apostille can only be used between the two countries once the convention enters into force for Thailand on 28 February 2027. Until then Thai documents follow MFA legalisation plus destination-embassy attestation. Check current status at hcch.net.

They are four separate layers: (1) translating the content, (2) the translator's certificate of accuracy, (3) attestation of a signatory's signature by a lawyer authorised to certify signatures and documents, and (4) legalisation or apostille certifying the seals for cross-border use. The first three cannot replace the fourth.

If the destination requires a translator based in that country, legalise in Thailand first: the translator must render every stamp inside the translation. If the destination accepts a translation prepared in Thailand, translate and certify first, then legalise the translation.

Acceptance is at the receiving authority's discretion, so we do not guarantee outcomes. We confirm the required certification system and document age before starting, and redo our translation work free of charge if the error is on our side.
