A national of Australia marrying in Thailand — what does translation and legalisation require?

This question is specifically about “A national of Australia marrying in Thailand”, so it covers both the requirements attached to this document set and the order the steps must follow. Plan the schedule with room for at least one review cycle at the receiving office. With a fixed filing date, count backwards from it and book each certification step in reverse. Attach a document index to the bundle so nothing is lost during review. High-resolution photos of seals and signatures help when the destination asks for re-verification. After certification, scan the full set before it leaves your hands. The specifics here are destination: Au, and those decide which translation and certification level applies.

The deciding factor is the receiving body's requirement, not only the format of the Thai-side document. Before starting, ask in advance which category of certified translator the destination accepts, then plan the timeline so certification finishes before the real filing deadline, then keep a digital copy of every page, including seals and signatures.
