Using Thai marriage documents with Australian authorities: translation requirements explained
In short
Australian authorities assess documents that are not in English together with a translation. Where the translation is produced in Australia it must come from a NAATI-certified translator; where it is produced outside Australia it must show the translator's full name and contact details. Thai marriage records are lodged as a scan of the original plus the translation, both legible and complete.
Who this applies to
- • Applicants for Australian partner or family visas who married in Thailand.
- • Australian citizens and permanent residents sponsoring a Thai spouse.
- • Anyone lodging Thai marriage records with an Australian government body, court or institution.
Documents to prepare
- • Marriage certificate (Kor Ror 3), freshly issued copy
- • Marriage register record (Kor Ror 2) where full detail is requested
- • Passport bio page of each party, for name consistency
- • Change-of-name evidence where a name differs from the passport
- • Divorce certificate (Kor Ror 7) or court judgment, where a previous marriage ended
Step by step
1. Read the checklist for the exact visa subclass
Document requirements are set per application type on the Department of Home Affairs website. Work backwards from that written list rather than from general advice.
2. Obtain freshly issued copies from the registrar
Order copies close to the lodgement date so the set is current when the case officer opens it.
3. Scan every page in full colour
Seals, signatures, document numbers and any handwritten notes must be legible. Phone photos with shadow across the seal cause avoidable requests for more information.
4. Order a NAATI-certified translation
The translation renders the whole document — letterhead, seal text, endorsements and marginal notes — and is returned as a digitally signed PDF suitable for online lodgement.
5. Lodge the original and the translation together
Upload each translated document alongside the scan of its original, using clear file names that match the checklist item.
Points to watch
- • Uploading a translation without the scan of the original document.
- • Name spellings differing between the marriage certificate, passport and other evidence, with no change-of-name evidence attached.
- • Translating only the front page and omitting endorsements on the reverse.
- • Assuming consular legalisation is required for Australia — for most Australian purposes a compliant translation of the original is what is assessed.
Frequently asked questions
Must the translation be done in Australia?
No. Translations produced in Australia must come from a NAATI-certified translator; translations produced outside Australia must show the translator's full name and contact details. Many applicants outside Australia still choose NAATI-certified translation because it removes doubt at the assessment stage.
Is a digital PDF translation accepted for online lodgement?
Online applications are lodged with uploaded files, so a digitally signed PDF is the practical format. Where a paper original is specifically requested by the receiving office, we can arrange a printed and signed copy as well.
Do we need the marriage certificate legalised by the Thai MFA?
Consular legalisation is a requirement of certain other countries. For Australian authorities the published requirement concerns the translation, so follow the wording of your checklist and ask us if it is unclear.
Our names are transliterated differently on two documents. What now?
Include change-of-name or supporting evidence and keep one consistent transliteration across the translated set. Tell us the passport spelling before we begin so the translation matches it.
Can you do this while we are outside Australia?
Yes. The service is online worldwide: send scans by LINE or email and receive digitally signed PDF translations in return.
