Current or future cohabitation couples can enter into a cohabitation agreement (Sw. samboavtal) by which they can agree that some of the provisions in the Swedish cohabitation act should not apply to their relationship: that no housing split (Sw. bodelning) should take place or that certain property should not be included in housing split when the cohabitation relationship ends. A cohabitation agreement must be in writing. Consequently, it could be a good idea to enter into a cohabitation agreement if one of the cohabitants pays for a joint residence or other expensive property intended for joint use. Without a cohabitation agreement in those situations, the property risks being part of the housing split regardless of who paid for it or who owns it. Naturally, it is possible to amend a co-habitation agreement by entering into a new co-habitation agreement.
