Many people change their names without taking any formal action, as there is no law to prevent people using any name they choose. A change of name may be established by repute or usage, however there may be difficulties when using the name for official purposes if the name change has not been properly registered.
Any person over the age of 18 years can change his or her name by obtaining the appropriate form from the Births, Deaths and Marriages Registry and paying the fee.
The completed form must be signed and witnessed in the presence of a Justice of the Peace and lodged with a certified copy of the applicant's birth certificate and two forms of identification. Registration takes five working days and a registration certificate can then either be collected from the Registry or arrangements can be made for it to be posted to the applicant.
There is a fee to register a change of name, which includes a Change of Name Certificate or an amended Birth Certificate. If a person is unable to visit the Registration Office, they can telephone 131 882 to discuss alternatives and further information about what is required is available on the sa.gov.au website.
Change of name on marriage
There is no law requiring a woman to take her husband's surname on marriage. If a woman does decide to adopt her husband's name, no formal registration of the change is needed. Generally, it is sufficient for the wife to inform the relevant agencies and institutions of the marriage and the change of name. Sometimes (such as when applying for a passport) it may be necessary to produce the marriage certificate. It is also legal for women to keep their premarital names for professional or business affairs while using their married names in their private lives.
Change of name on separation or divorce
A woman may choose to keep her husband's name after the marriage has been dissolved or she may go back to using her premarital name. There is no need for a woman to wait until the divorce is final before changing her name. A woman who remarries may adopt her new husband's surname or use her first husband's name, or her premarital name.
