If you want an agreement to reflect your interests and protect your assets upon living with a partner, then you should consider obtaining a Cohabitation Agreement.
Those who do not marry and simply live together, unfortunately are not afforded the same rights as a married couple upon separation, with regard to property and assets. It is, therefore, important at the outset of cohabitation to consider protecting your assets by having a Cohabitation Agreement.
This should clearly set out each party’s interest in the family home and what will happen to the property should the relationship break down in the future. This would avoid any unnecessary court proceedings and/or high legal costs should you separate.
Where parties do not have such an agreement drawn up and ultimately the relationship ends, there can be real difficulties in resolving how the family home is to be dealt with, even if the property is registered in joint names.
