Some Family Law issues affecting common law couples
Anything you acquire with your money during the relationship and hold in your name belongs to you. You should try to keep receipts and other proof of ownership. However, things you and your common law spouse buy together during the relationship belong to you jointly. On separation, these would be divided.
Exceptions to the general rule that each common law spouse owns what he/she brings in the relationship:
i. Where there is a cohabitation agreement. This agreement can indicate how the parties intend to arrange their finances or other aspects of their lives together or how they want to deal with their debts or assets when they separate; how their properties would be divided and what support would be paid etc.
ii. Where a common law spouse has contributed time, money or work that assists the other spouse to buy, maintain or improve the value of his/her property.
In such a case, the common law spouse who owns the property can compensate the other spouse. If he/she refuses to compensate the other spouse, the other spouse can go to court to prove his/her contribution and the court will decided if he/she should have a share in the property and the amount of compensation. It is the contribution, not the common law relationship that entitles the other spouse to a share in the property.
