Changing Your Name
Changing your name in Western Australia
If you want to use a different name, you can change your name informally by asking people like family, friends and your school to call you a different name. You didn’t need to fill in any forms for this. Changing your name informally is a free and easy way to change your name, and it gives you time to decide if you want to stay with your new name or change it back.
But if you change your name informally like this, you might run into problems when you apply for your driver’s licence, a passport, a Medicare card or Centrelink because there’s no official record to show that you’ve changed your name.
If you’re under 18 and you want to change your name formally, you’ll generally need the permission of both of your parents/guardians. Your parents/guardians will have to apply to the Registry of Births, Deaths and Marriages. To change your name in Western Australia, you need to have been born there or lived there for over 12 months.
If you weren’t born in Western Australia and you haven’t lived there for at least 12 months, then you need to apply to change your name in the state/territory you were born in/have lived in for a certain period of time. To find out how about the laws in other states, please click Change State at the top of the screen.
Generally both of your parents or guardians will need to sign the form to change your name unless:
- only one parent is named on your birth certificate; or
- one of your parents has died or;
- one of your parents/guardians applies to the Family Court to get an order to change your name because they think this is in your best interests.
- you’re under 18 and married, or you have been married before. If you’re in this situation, you don’t need anyone’s permission to change your name - see the section on Over 18’s (below).
To get an application form to change your name visit: Government of Western Australia Births, Deaths, Marriages
It costs $156 to change your name formally.
Your parents/guardians will have to provide evidence to prove that they are your parents/guardians. They will also need to show some documents that prove who you are. For more information on what documents you need to show to change your name, visit Part 5 of the application form here: Government of Western Australia Registry of Births, Deaths & Marriages.
We sometimes get asked by young people if their parents can change their name without their permission, for example if one parent wants you to use their name after a family divorce.
If you’re over 12 years old, your parents can’t change your name unless you agree or a court decides that it’s in your best interest. In deciding what’s in your best interests, the court will take into account your views, but they don’t have to follow them. Other things the Court can consider include:
- how you feel about each parent;
- how often you see both of your parents;
- any feelings of being confused about your identity; and
- if you’ll be embarrassed by having a different name from the person you normally live with.
If you were born in Western Australia or you have lived there for over 12 months then you can apply to the Registry of Births, Deaths and Marriages to change your name.
If you are under 18 and you are married (or have been married before), you can change your name in the same way.
