A Notice of Intended Marriage (NOIM) must be filed at least one month before your wedding day. Marriages in Victoria must be officiated by a licensed celebrant, such as: Some regional courts have territory officers (contact your local court for details) who can perform marriages. Or you can file out-of-state if you're not resident in Australia. You'll need to provide some documentation that you are legally able to marry someone else, including proof of identity and residence. Your spouse's identity may be verified through a birth certificate or passport. If they do not have either, they will need to provide two documents indicating their name change and new identification. Your marriage license will include the date and location of your wedding ceremony, as well as the names of any witnesses who will sign the document. You will need to show up on time with no delays at your chosen location. If you fail to do so, your marriage will still take place but it won't be legal until after your delayed ceremony. You cannot marry outside of Victoria without filing a lawsuit and winning an order from the court. This is called "bigamy" and is illegal in almost all states. However, in Canada, British Columbia was once again singled out by the province's Supreme Court as being different from the other provinces where bigamy is also prohibited.
