The Registry's Public Counter and Marriage Services are open to the public. For your safety and the safety of our staff and other customers, we ask that you postpone your visit to the Registry if you are unwell. All visitors are encouraged to observe the Department of Health's physical distancing guidelines and to make use of the additional hand sanitisation stations during your visit.

Visitors are also required to provide contact details for the COVID-19 Contact Tracing Register. Customers can check-in by scanning the unique QR Code using the SafeWA app or by providing your details to the Registry Officer at the Public Counter.

There may be a limit on the number of guests that can attend a marriage ceremony at the Registry to ensure that recommended physical distancing requirements are met.

If you are using, or wish to use, a name other than your registered name, there is no legal requirement that you formally change your name. It is, however, recommended that you change your name officially, both for identification and as evidence of your name change.

How to register a change of name

Show more

To register a change of name, you need to apply to the Registry of Births, Deaths and Marriages in the State or Territory of your birth.  If you were born overseas, you must be a permanent resident or an Australian citizen and ordinarily residing in Western Australia for 12 months immediately preceding your application. All applications to register a change of name require three forms of evidence-of-identity documentation.

Once your application is approved, you will need to apply for a change of name certificate (this is separate to the registration fee) which authorises the use of your new name.

If you were born in Western Australia, your original name will remain on your birth certificate and your new name will also appear on the certificate as a notation. Your birth certificate with the change of name notation is available upon application and payment of an additional fee.


You must be 18 years of age or older and born and/or had your birth registered in Western Australia to change your name using the BDM400 Register a Change of Name (Adult) application form

You can only change your name once in any 12 month period unless there are exceptional circumstances such as personal safety issues.


Parents and legally appointed guardians may wish to change a child's name for a variety of reasons. There are several methods of changing a child’s name.

Changing a child’s given name/s within 12 months of their birth
Children under 12 months of age who were born in Western Australia can have their given name(s) changed by completing a BDM105 Application to Change a Child’s Given Name within 12 months of their Birth form.  A fee is payable for this service and only one change of this kind can be made within the 12 months of the child's date of birth.

Changing a child’s name – given and/or surname
This applies to:

  • changing your child’s given name(s) after 12 months of their birth; or
  • changing your child’s given name(s) and/or surname from their date of birth up to when they turn 18 years old.

If your child was born and/or had their birth registered in Western Australia you must apply to the Registry for a change of name using the BDM401 Register a Change of Name (Child under 18 years) application form.

Where one parent of a child cannot obtain the consent of the other parent named in the child's birth certificate, a court order from the Family Court, stating that it is in the child's best interests to have their name changed, must be obtained before the Registry can register a change of name for the child. 

A child’s surname can also be changed following the addition of their parent’s marriage or the child’s parentage details to their birth registration.  Please refer to the Corrections and Amendments webpage for further details.

Where a family applies to change their name together (ie legally married or de facto couples, different or same sex) all applications for children of that family under 18 years of age are not charged a fee, ie each adult applicant pays a full fee and for each child no fee is payable.

Each family member must complete a separate application form and a separate fee is payable for all change of name certificates (this is separate to the registration fee).

Proof of residency

If you were born overseas, you must provide a minimum of two separate forms of documentary evidence to show you have been living in WA for the 12 months immediately preceding your application.

Evidence should:

  • not be older than twelve months (except your Western Australian photo driver's licence)
  • state your current address and, where applicable, all previous Western Australian addresses within the last 12 months
  • display the date of issue of the document
  • clearly show a 12 month history of your living in Western Australia
  • be certified as true copies by an authorised person.

In extraordinary circumstances, the Registry may accept evidence older than twelve months but only where they clearly link to other forms of evidence of residency in Western Australia. Please contact the Registry to discuss before lodging your application.

By signing the change of name application you are authorising the Registry to conduct discretionary checks (if required) with appropriate agencies to verify the information in your application including the authenticity of your documentation.

Change of name after marriage

Show more

Any person who marries in Australia may choose to assume their spouse's surname. This is done as a matter of custom, not law.  A certified marriage certificate issued by an Australian Registry of Births, Deaths and Marriages is usually sufficient evidence to have personal documentation changed to a married surname.

If you were married overseas, you may have to register a formal change of name with the Registry before your married surname is accepted by some organisations.

If you wish to revert back to your maiden name (surname at birth or after adoption), there is no legal requirement for a formal change of name, however, to avoid difficulties with obtaining recognition of your maiden name, registration of the change is recommended.

Adding a previously registered change of name to your birth certificate

Show more

If you were born in Western Australia and have previously changed your name via Deed Poll or a prior Registry Change of Name License, you can have this recorded on your birth registration using the BDM104 Application to Record a Previously Registered Change of Name in a Birth Registration form. If the change was registered in another State or Territory, a certified copy of the change of name certificate must be submitted with your application. 

No fee is payable for this service, however, if an amended birth certificate or change of name certificate is required a certificate application form must be submitted along with the required fee.

How to apply for a previously registered change of name certificate

Show more

Certificates for a change of name previously registered in Western Australia from 31 January 1957 can be obtained from the Registry by applying online or by submitting a BDM450 Previous Change of Name Certificate Application Form.  If the change occurred in another State or Territory, contact the relevant Registry Office.

Enquiries regarding change of name certificates prior to 31 January 1957 should be directed to Landgate.
