You can include in your marriage contract: a cohabitation contract is a written document that you and your common law partner can create before or during your life together. It`s a kind of domestic contract that tells how you`re going to handle problems while you`re together or at the end of your relationship. Concubine agreements are a useful instrument for unmarried couples to sketch out from the outset what will happen financially if the parties separate, especially since unmarried couples do not have the same rights as married couples. Please see our page on unmarried couples and separation for further instructions. The conclusion of a concubine contract gives concubnats the flexibility and freedom to organize their financial affairs as they wish, both during and after cohabitation. In addition to the assets you may have, a concubine agreement also defines the distribution of all debts between the two of you. It may even cover the issue of assistance to spouses. The parties may often find it difficult to ask the question of entering into a cohabitation contract with their partner, especially when the couple is going to cohabit in a property owned exclusively by one of them.. . .
