How a registered change of name works in SA

The modern process for changing your name in South Australia is through registration with Consumer and Business Services. This replaces the old-style 'deed poll' terminology that some may still search for.

To apply, you'll need to complete a change of name form. This form must be signed in the presence of a Justice of the Peace. Along with your application, you'll need to provide a certified copy of your birth certificate and two forms of identification.

Once your application is processed, you will receive a new change-of-name certificate, which serves as legal proof of your new name.

Who can apply in South Australia

To apply for a change of name in South Australia, you must meet certain residency and birth requirements. You can apply if you were born in South Australia or, if born overseas, you are an Australian citizen or permanent resident who has lived in SA for at least the last 12 months.

For children, parental consent is required for a name change application. Keep in mind that there are restrictions on changing to prohibited names, which you can check with the registry.

After it's registered: updating everything

After your name change is officially registered, the next step is to update your details everywhere necessary. This includes notifying agencies such as the Department of Transport for your driver's licence, Passport Office, Medicare, Australian Taxation Office, and your banks.

Don’t forget to inform your superannuation fund and any other memberships or loyalty programs you may have. For assistance with notifications, consider using the Change Your Name service.
