Which Thai documents must be translated to marry in Australia?
Usually proof of date of birth such as a birth certificate, plus evidence that any earlier marriage has ended — a divorce decree or death certificate — each with a certified translation.
In-depth Answer
Marrying in Australia begins with lodging a notice with the celebrant within the statutory lead time, and the celebrant must verify two things: age and marital status.
Thai applicants typically prove age with a birth certificate or passport page, and prior marital status with a divorce decree or a former spouse's death certificate — translated when issued in Thai.
Confirm with the celebrant whether printed copies are required or digital files suffice, as practice varies.
If you plan to later record the marriage in Thailand, retain the full source-and-translation set: the Thai process needs the Australian documents translated in the other direction, and keeping a record of the agreed name spellings keeps both jurisdictions consistent.
