Name change in Western Australia
Married in Australia? Your marriage certificate is proof, nothing to register. A new name, an overseas marriage, or a spelling fix needs a formal change with the WA registry first.
Married in Australia? Your official marriage certificate is proof across WA. Nothing to register.
Choosing a new name, married overseas, or fixing a spelling? Register a formal change of name with the WA Registry of Births, Deaths and Marriages first, about $172.
Either way, update your WA driver licence and Medicare first. Once those show your new name, everyone else accepts it with far less fuss.
Married in Australia and taking, adding or hyphenating your partner's surname? Your official marriage certificate is proof across WA. Nothing to register.
A brand new name, a gender-affirming change, a spelling fix, or a marriage overseas is different. Register a formal change of name with the WA Registry of Births, Deaths and Marriages first, about $172.
Where you apply depends on where you were born, not where you live now.
Complete the change of name application for WA. Provide your identity documents, including at least one with a photo. Then pay the fee and lodge it, online, by post, or in person.
Fees change over time, so check the registry for the current amount before you pay.
Once you lodge a complete application, the certificate is typically issued within a few weeks. A faster priority service is often available for an extra fee.
This becomes your legal proof everywhere else. Updating everyone afterwards is the part Surname Switch speeds up.
Update your WA driver licence through the Department of Transport first, in person with your original certificate. Then Medicare. New photo ID speeds up banks, super and everyone else on your list.
By situation
Straight from the app that builds your WA checklist. Fees are the state registry's, not ours.
| Your situation | Register with WA BDM first? | What proves your name | Typical cost |
|---|---|---|---|
| Married in Australia | No | Your official marriage certificate | Free |
| Married overseas | Often, if a place won't accept your certificate | Overseas marriage certificate, or a WA change of name certificate | Free, or about $172 if you register |
| Choosing a brand new name | Yes | WA change of name certificate | About $172 |
| Reverting to a former name | Usually not | Your previous marriage certificate, divorce order, or change of name certificate | Free |
Married overseas and a WA organisation won't accept your certificate on its own? Registering a WA change of name gives you an Australian-issued certificate they will accept.

Do it at the source
Eligibility is narrower than most states: based on where you were born, not where you live. WA does not accept applications by email or fax, only online, by post, or in person.
Do your driver licence first, through the Department of Transport. It becomes accepted photo ID, so Medicare and everyone else accept your new name with far less fuss. See the order that works best in our full checklist.
Married in Australia? See our marriage guide for what changes and what does not. Reverting to a former name is in our divorce guide; a brand new name, our deed poll guide.

Western Australia name change questions
Straight answers to what people in Western Australia actually ask about changing their name.
Married in Australia? Your marriage certificate is proof, no registration needed. Choosing a new name, affirming your gender, or married overseas? Register with the WA Registry of Births, Deaths and Marriages first. Either way, Surname Switch prefills forms, drafts emails and tracks every organisation.
Free if your marriage certificate is your proof. A formal change costs about 172 AUD, paid to the registry. Fees change, so check their site for the current amount. Surname Switch prepares your notifications from $25, no subscription.
Usually not. If you married in Australia and are taking, adding or hyphenating your spouse's surname, your marriage certificate is enough. No separate registration with the WA registry is needed. A formal change is only needed for a new name, gender-affirming change, spelling fix, or overseas marriage.
Formal changes are registered with the WA Registry of Births, Deaths and Marriages. You generally apply if you were born in WA, or born overseas and living in WA the last 12 months. Born in another state? Apply there instead, wherever you live now.
Once you lodge a complete application, the certificate is typically issued within a few weeks. A faster priority service is often available for an extra fee. Updating everyone afterwards takes longer. That is what Surname Switch speeds up.
You update your WA driver licence through the Department of Transport, usually in person, with your proof of name change. Do this first: once your licence shows your new name, other organisations accept it with little fuss.
Yes, through the same WA registry that handles adults. It generally needs consent from both parents, or everyone with parental responsibility, or a court order without agreement. The registry sets out the exact forms.
It depends on the organisation. Some accept a clear photo or scan. Others need a certified copy, verified by a Justice of the Peace or pharmacist. Order a couple of certified copies up front.
A foreign marriage certificate often is not accepted alone by WA organisations. The clean path is usually to register a formal change of name first, then update everyone with that certificate. Our questionnaire checks this for you.
Your forms prefilled, every email drafted, and one ordered checklist of your actual companies. Plans from $25.
