Is it possible to have a binding pre-nuptial or pre-relationship agreement?

The Family Law Act provides for binding financial agreements to be made between parties to a marriage, a de facto relationship or a same sex couple. These agreements can be made before, during or after the end of the marriage or relationship. Parties entering into a relationship agree what will happen in the event that they separate. Parties entering into a second relationship or with substantial assets often like the protection of a financial agreement.
