Change Your Name After Marriage in South Australia
There is no legal requirement to change your name after marriage in Australia. Many people do, many people do not, and some use different surnames in different parts of life.
Common Options After Marriage
After marrying in South Australia, you may choose to:
- keep your current surname
- take your spouse’s surname
- add your spouse’s surname
- use a hyphenated form
Whether an organisation accepts a particular format depends on that organisation’s own rules.
The Certificate You Usually Need
For most administrative name updates, you will need the official marriage certificate issued by South Australian Births, Deaths and Marriages if you married in South Australia.
Your ceremonial certificate from the wedding day is not usually enough for official record changes.
See South Australian marriage certificates for the process.
When a Formal Change of Name May Be Needed
If you want something outside the usual post-marriage surname options, such as:
- creating a new combined surname
- changing to a name not obviously supported by the marriage certificate
- formalising a different legal identity
you may need a separate legal change of name process through Births, Deaths and Marriages.
Organisations People Commonly Update
After marriage, people commonly update:
- driver’s licence
- passport
- Medicare
- banks
- superannuation
- employers
- insurers
- professional registrations
Each organisation sets its own documentary rules, so check before you attend.
Adelaide Practical Tip
If you know a name update is important for travel, visas, or work, order the official certificate as soon as your marriage has been registered.
