NAATI certified birth certificate translation for Australian authorities
A birth certificate is one of the most frequently requested documents in Australian visa applications. It establishes identity, date of birth and parentage in a single document, which is why partner, child, parent and citizenship applications all rely on it.
In short
A birth certificate not written in English must be lodged together with an English translation. If the translation is prepared inside Australia it must be produced by a translator certified by NAATI for that language direction. If it is prepared outside Australia, the translation must show the translator's full name, address, contact details and qualifications. In practice the NAATI certification format is the one Australian agencies recognise most readily.

When this document is required
- Partner and prospective marriage visas (subclass 820/801, 309/100, 300) — identity of the applicant and any children
- Parent and family visas (subclass 143/173/103) — proof of the parent-child relationship
- Student visas with dependants under 18 (subclass 500/590)
- Australian citizenship applications and passport applications for a child
- School enrolment and state registry matters within Australia
Which original to send
- The original certificate, or a freshly issued certified extract from the civil registry — avoid uncertified photocopies
- If the original is lost or damaged, request a replacement or a certificate of birth registration from the issuing registry office
- The photo page of the passport of the person named, so the English spelling on the translation matches the travel document
Checklist before you send scans
- Scan in colour at 300 dpi or higher with all four edges of the page visible
- Always include the reverse side if it carries stamps, signatures or annotations
- Check that the document number, date of issue and issuing office are legible
- Provide passport spellings for every person named — the child, the mother and the father
- Tell us which body will receive the document so the right stamp format is used
Common reasons a translation is questioned
- Name spelling that differs from the passport — the most common reason a translation is queried
- Sending only the front page, so stamps or corrections on the reverse never reach the translation
- Using an uncertified photocopy, which invites questions about the authenticity of the source
- Printing and re-scanning a digitally signed PDF, which breaks signature validation
Frequently asked questions
Do I also need consular legalisation or an apostille?
For most lodgements with Australian authorities a certified translation is sufficient and no apostille is required. If the document is being used for a foreign registry or court matter, confirm the requirement with the receiving body first.
Can you translate a birth certificate issued outside Thailand?
Yes. We work with certified translators across many language pairs. If no certified translator exists for a particular pair, we say so in advance and set out the alternative format the receiving body accepts.
Does the whole document have to be translated?
Yes. Full-document translation is expected, including stamps, seals, marginal notes and anything handwritten. Partial translations are frequently rejected.
How long is a certified translation valid?
The translation itself does not expire, but some agencies ask for a recently issued source document. Check the receiving body's rules on document age before lodging.
