Typical family agreements are marriage contracts, concubine agreements and separation agreements. 82 This Part does not affect the rights and remedies of creditors, guarantors or spouses in respect of family debts. You and your spouse can make a written agreement (sometimes called cohabitation or marriage contract) while you are cohabiting. An agreement between two or more persons that imposes reciprocal obligations on them that can be applied in court. A valid contract must be offered by one person and accepted by the other, and some form of payment or other value must normally be exchanged between the contracting parties. The same test is used to set aside the parts of the contact agreements.
