Changing your last name after marriage or separation

Changing your family name after marriage

If you married in Australia:

• you can take your partner's family name
• both partners can hyphenate their family names.

You don't need to apply to the Registry of Births, Deaths and Marriages to change your name.

You can use your marriage certificate to change your name with organisations.

Born overseas and married in Australia

If you were born overseas and married in Australia, organisations may accept a copy of:

• an identity document (passport or Australian citizenship certificate) and
• your official marriage certificate.

Some organisations may need an official change of name document.

This might be due to:

• divorce
• personal choice.

To update your family name, contact each organisation to find out what they need. You may need your:

• official marriage certificate
• official birth certificate
• divorce document.
