Information you need to register a change of name or apply for a change of name certificate is below.
You can register a change of name in South Australia if you:
- were born in South Australia; or
- were born overseas and are an Australian Citizen or permanent resident and have been a resident here for at least 12 months.
If you were born interstate you must apply to the State/Territory where your birth is registered.
If you are a serious sex offender, serious violent offender, prisoner or parolee you will need to have authorisation from the relevant authority before applying (refer to the change of name form for more information)
Only one change of name is allowed in any 12-month period. Only three changes are allowed in a lifetime.
You can legally assume a new name without getting your new name registered. If you do assume a new name and don’t get it officially registered, you may have difficulty – eg when renewing your passport – because you don’t have documentary evidence of your name change.
Married women – if you want to take your husband’s surname, and you were married in Australia, you do not need to register a change of name.
Married men – if you want to take your wife’s surname, please contact the Government agency or commercial organisation concerned to determine what evidence is required.
After divorce – a woman can revert back to her previous married surname or birth surname at any time after divorce without having to register the name.
Children – a child’s name cannot be changed unless the child has consented to the name change.
If a child is too young to understand the implications of a name change, the new name can still be registered. A qualified person – eg a Births Deaths and Marriages staff member, Justice of the Peace, solicitor or police officer – is the only person who can determine if a child is too young to understand the implications.
Overseas marriages – your overseas marriage certificate may not be accepted by all government and other agencies. Please check with the relevant authority to find out their requirements prior to registering a change of name
- Step 1 – fill in the relevant form – see Forms and fees section
