Register a change of name

You don’t need to register your new name with Consumer and Business Services (CBS) if you:

  • get married in Australia and take your partner's surname
  • decide to go back to your surname before marriage.

You should provide a copy of your official marriage certificate to the relevant authority (ie Australian Passport Office) as evidence of your new surname.

If you were married overseas and want to take on your partner’s surname, you should contact the relevant authority or business, such as your bank or the Australian Passport Office to see what evidence you need to give them.

To change your name on documents such as your passport or driver’s licence, you must do so directly with the relevant authority, such as Service SA or the Australian Passport Office. They'll tell you what evidence you need.

Who can register

You can register a change of name with CBS if:

  • you were born in South Australia
  • you were born overseas, but you are an Australian citizen or a permanent resident and have lived in South Australia for at least the last twelve months.

CBS can accept one name change every 12 months, and you can only change your name three times in your lifetime. Permission from the relevant authorities is required for:

  • serious sex offenders
  • serious violent offenders
  • prisoners
  • parolees.

What you'll need

You’ll need to provide information:

  • your new name
  • any previous names used
  • the reason for changing your name.

We'll email you a declaration to be signed in front of a registry approved witness. Registry approved witnesses include:

  • justices of the peace
  • notary publics
  • police officers
  • practising solicitors/lawyers.

View a full list of registry approved witnesses.

Proof of identity

You need to prove your identity, unless you're applying for a birth certificate that's more than 100 years old.

You'll need to provide one of these combinations of documents:

  • TWO documents from list 1
  • ONE document from list 1 and ONE document from either list 2 or 3
  • ONE document from list 2 and TWO documents from list 3
  • THREE documents from list 3.

At least one document must show your name and address and one document must show your signature.

All identification documents must be current (not expired). Where a document from list 3 is provided as evidence of your address, it must have been issued within the last three months.

You can upload scanned or photographed images of your ID documents.

If you're applying online, you must include a document from list 1, or your Medicare card, if agreeing to be verified by the online Document Verification Service (DVS). If you live overseas, you can use your overseas driver’s licence or passport.
