Legal Change of Name in Australia — BDM Eligibility, Documents, State Differences
Legal changes of name in Australia are registered by each state's BDM. This guide sets out the differences in eligibility, documents, fees, limits on the number of changes and using a spouse's surname after marriage, focusing on NSW, WA, QLD and VIC.
Overview — the state BDM registers legal name changes
In Australia, change of name registration, which changes your name in the official record, is handled by the Registry of Births, Deaths and Marriages (BDM) that each state and territory has separately. Which state you can apply to, the documents and the fees differ by state, so first check which BDM you need to apply to. The official WA guidance says you are not required to legally change the name you normally use, but recommends official registration for proof of identity and as evidence. This guide covers change of name registration for adults; it does not cover changes to the gender recorded on documents or the effect under your home country's law. A child's change of name has a separate application process, so ask the relevant BDM.
Using a spouse's surname after marriage may not need registration
If you married in Australia, the states we checked (NSW, WA, QLD, VIC, SA) say you can use your spouse's surname with your official marriage certificate, so a separate change of name registration is not needed. However, qualifiers such as 'most' and 'usually' are attached, and QLD and VIC add that, for people born overseas, some organisations may require official change of name documents. If you married overseas, NSW and VIC say a change of name application is needed. For updating your name with each organisation, see the 'Matching names on official documents' guide, and for marriage registration, the 'Getting married in Australia' guide.
Registration — application, assessment, certificate
Change of name registration proceeds in this order: application → assessment of identity and residency documents → registration → issue of the change of name certificate. People born overseas receive a change of name certificate (QLD and VIC guidance), and this certificate is the document linking your previous and new names when you change the name on your licence, passport and bank accounts. NSW, VIC and QLD also set out naming rules under which names that are inappropriate or too long, or that contain symbols or numbers, among others, are not registered.
Fees and refunds — you may not get your money back
Checked November 2026; fees may change every year. For adults, fees are NSW $203 ($70 extra for the certificate), WA $206 (lodgement fee, $60 extra for the certificate), QLD $220 (including 1 certificate), VIC $148.60 (including the certificate) and SA $322 (including the certificate). WA says it keeps the lodgement fee regardless of the outcome of the application, and QLD says there is no refund if the application is refused or cancelled after assessment.
- Identity documents — NSW, WA and QLD require 3 types; VIC and SA require combinations of documents from their lists
Eligibility — which state can you apply to?
Eligibility often depends on place of birth. If you were born in another Australian state, NSW, WA and VIC say to apply to the BDM of your state of birth, and QLD follows the same principle but lets you apply for an exception if you have a good reason and evidence. TAS also lists people born in another state who have lived in TAS for 12 months or more, and the ACT application form lists current ACT residents, as able to apply (as of the first half of 2026). Adults born overseas can apply if they meet the requirements of the state where they live, and the requirements differ by state (checked November 2026). Check the following three points.
- Residency period — adults born overseas: NSW, 3 continuous years immediately before applying; WA, 12 continuous months immediately before applying; QLD, VIC and SA, the most recent 12 months
- Residency status — for people born overseas, WA and SA require citizenship or permanent residence, and VIC requires 'the legal right to live in Australia' (not defined in the original wording)
Comparing application requirements by state
This is a summary for adults born overseas (checked November 2026; may change). SA is covered in the eligibility points above, and TAS, ACT and NT (as of the first half of 2026) in the eligibility information above and in the FAQ, so check the relevant BDM for the latest.
You prove continuous NSW residence for the 3 years immediately before applying with 4 documents. You need 3 types of identity documents (including 1 government-issued photo ID), a declaration of any conviction for an offence punishable by 12 months' imprisonment or more, and consent to a police check. Registration fee $203 ($233 for priority), certificate $70 extra, online up to 5 weeks (security checks of up to 10 business days extra).
People born overseas must be citizens or permanent residents who have lived continuously in WA for the 12 months immediately before applying, and must provide 2 or more pieces of proof of residence. The $206 lodgement fee is kept regardless of the outcome, and the certificate costs an extra $60. The BDM400 form is accepted by post or by visiting the Perth registry; email and fax are not accepted.
This applies to adults born overseas who live in QLD and have spent the past 12 months in QLD; if you have not met this, you can apply for an exception with a reason and evidence, but the application is cancelled if the exception is not approved. Submit the 3 types of identity documents (including proof of your current address) as certified copies, and documents not in English with a NAATI translation. $220 (including 1 certificate); lodged by post or booked visit.
Preparation and lodgement tips
First-time applicants easily overlook these preparation steps. Some states do not refund the lodgement fee, so check before you lodge.
- Decide the state first. Check the state-of-birth principle (NSW, WA, VIC), the QLD exception, applications by residents in TAS and the ACT, and the state-of-residence requirements for people born overseas.
- Gather proof of residence in advance. NSW requires one document each from 3 years ago, 2 years ago, 1 year ago and the last 3 months, 4 in total.
- Arrange certified copies and translations. QLD, VIC and SA require certified copies. See the 'JP certification & certified copies' and 'NAATI certified translation and interpreting' guides.
Common mistakes and misunderstandings
The mistakes below can lead to losing a non-refundable lodgement fee or having to apply again.
- Lodging without checking your place of birth or residency period. WA keeps the lodgement fee regardless of the outcome, and QLD also says there is no refund if the application is refused or cancelled after assessment.
- Assuming one rule for using a spouse's surname after marriage. For a marriage in Australia, a marriage certificate is generally enough, but some organisations may require change of name documents, and for a marriage overseas NSW and VIC advise applying.
