Marriage was a very traditional institution in Colombia, however, many couples chose to start a sentimental relationship, as a couple, without marriage. This type of union generated multiple lawsuits for the assets acquired in the course of the relationship. For this reason, the legislator enacted Law 54 of 1990, through which de facto marital unions were formalized in Colombia, particularly with regard to the patrimonial regime. Law 54 of 1990 establishes a legal presumption, according to which, once the marital union has been proved in fact for a period of 2 years, it is presumed to be a patrimonial company of goods, having the right to liquidate it. The issue that concerns us has to do with marital unions that do not reach 2 years, but in which the couple in solidarity and jointly have built a heritage, a capital. This work is aimed at determining what happens with the assets, with the patrimony, in the cases in which the couple does not have the two (2) years that the law determines.
