Concubine agreements usually deal with issues such as the division of property and debt or whether assistance to spouses is paid when the relationship ends. Before entering into a concubine agreement, you and your spouse must sit down and make a list: important legal rights could be lost if you are unable to prove that you were a common law couple in British Columbia. You need advice from a lawyer who knows the laws in British Columbia. In addition, that information relates to common law relationships. The lawyer would be experienced in proving the existence of such relationships. In addition, it is essential to protect your property and financial rights. Whatever you do, the main point is that it is important to regularly review the agreement to ensure that it continues to work for both parties and to ensure that it has not become significantly unfair.
