Some women who marry choose to change their surname to their husband's surname. This is done as a matter of custom and not of law.
Some women however do wish to formally change their name with the Registry. It's simply a matter of choice.
Keep Your Name
Can’t let go? Keeping your own name means you'll avoid the hassle of alerting everyone you know to the change. On the flip side, dealing with traditional in-laws who don't understand your reluctance to take their name won't be so simple.
Take His Name
Taking your husband's name is the most traditional option. Be prepared to receive twice as much junk mail -- mailing lists won't know you're the same person. But everyone else will figure it out, and you'll avoid confusion when you have kids.
Take His Name (Sort Of)
You could use your husband's name legally and socially but continue to use your own for business purposes; alternatively, you could keep your own name legally and professionally but use his in social situations.
Take Both
Or you could decided to keep both names and hyphenate them. If both names work well together, then this could be an option. It gets trickier if the names don’t work together or they have already been hyphenated; this then gets a bit much.
If you decide to change your surname to your husband's name the Roads and Traffic Authority (RTA) and the Passport Office need to view your official Standard Marriage Certificate issued by the Registry of Births Deaths & Marriages.
The RTA and Passports Office will not accept the Certificate of Marriage issued by the marriage celebrant on the day of the marriage, as it does not contain security features and can be easily reproduced. It also does not contain the full details of the parties to the marriage such as parents' details.
Institutions such as banks, the Passport Office and transport authorities require proof of identity so if you change your name you need to have proof of the change.
Please note, if you were married in
If you hold an Australian passport and want to change your name after you marry, be sure to change it within 12 months of the wedding - otherwise you will have to pay for a brand new passport. If you change it within 12 months, it is free of charge.
The new Australian Passports Act (Cth) 2005 means that if you no longer use your birth name, it may be difficult to get an Australian passport in the name you use, unless you can show documents that explain your change of name. In most cases, you will need to use your birth name on your marriage documents (unless you are using a previous married name). If you really do not want to use your birth name on your marriage documents, you may need to apply for a Change of Name Certificate with your local Births Deaths and Marriages Authority.
