Marriage Certificate
You will need to provide the Court with a copy of your marriage certificate. If you were married in Australia you can get replacement copies by contacting the Registry of Births, Deaths and Marriages in the capital city of the state where you were married.
If you cannot get a copy you will need to prepare an affidavit and file it with the Court. The affidavit needs to explain the details of your marriage and the reasons why you cannot get a copy of your marriage certificate.
Contact Fabian Horton if you need more information or help with preparing an affidavit.
