Change your surname after marriage

If you are changing to your partner’s surname, or adding their surname to yours, you do not need to go through a formal name change application process. You can use your official marriage certificate to prove your new name.

Surname options

  • You can take your partner’s surname
  • Your partner can take your surname
  • You can combine your name and your partner’s name with a hyphen

For any other change of name, you need to apply to change your name.

You will need an official marriage certificate

Sample of a standard marriage certificate with green tick, and sample of a commemorative marriage certificate with a red cross.

To update your married surname, you need an official marriage certificate (not a commemorative certificate) from the registry in the state or territory where you were married.

Married overseas?

If you were married overseas your certificate may not be accepted, and you may need to apply for an official change of name.
