Apply for a change of name certificate

Change of name certificates are usually needed when people want to prove their identity after they have registered a change of name for things like passports and claiming government benefits.

If you were married in Australia and wish to take on your partner's surname, you should apply for a marriage certificate as evidence of your new surname.

Who can apply

The person whose name is on the registration can apply for a certificate.

Other people who can apply are:

  • a child's parent, if the child is aged less than 18 years ­- evidence needed
  • a child's legal guardian, if the child is aged less than 18 years - evidence needed
  • an executor of their estate, administrator or trustee - evidence of authority needed
  • someone with written authority or power of attorney - evidence of authority needed.

The same eligibility covers birth certificates with a change of name noted on them.
