How to Change Your Last Name After Marriage in Australia (Simple Guide)

Many newly married couples choose to take their spouse’s family name after the wedding. It’s a long‑standing tradition in Australia, but it is not a legal requirement. You are free to keep your name, change your name, or use a combination—whatever feels right for you.

If you were married in Australia, the process is straightforward. You do not need to apply for a formal Change of Name through Births, Deaths and Marriages (BDM). Instead, your standard marriage certificate becomes your legal evidence of your new married name.

 

The Certificate You Need (and the One You Don’t)

The ceremonial certificate you sign on your wedding day doesn’t fulfil all legal requirements as proof that you are legally married. To update your name with government agencies, banks and other organisations, you must use a standard marriage certificate issued by the BDM office in the State or Territory where you were married.

As your celebrant, I always ask whether you’d like me to request this certificate when I register your marriage. This saves you time and ensures the certificate arrives as quickly as possible.

 

How to Change Your Name After Marriage

Once you receive your standard marriage certificate, you can begin updating your name with:

  • Government departments

  • Banks and financial institutions

  • Superannuation funds

  • Utility providers

  • Insurance companies

  • Phone and internet providers

  • Your employer

  • Memberships and subscriptions

  • Your doctor, dentist and other health services

Each organisation has its own process. You may be asked to:

  • Send a letter or email

  • Complete an online or paper form

  • Visit an office in person

What Proof Will You Need?

Different organisations require different forms of identification. You may be asked for:

  • Your standard marriage certificate

  • A certified copy of your marriage certificate

  • Updated photo ID (e.g., driver licence or passport)

  • A combination of identity documents

Tip: Start with your driver licence and passport first—once these are updated, everything else becomes easier.
