It is a figure that seeks to guarantee that the assets of a minor or an adult against whom the administration of his or her assets is exercised, do not enter the new property company that will be formed by his or her father, mother or legal representative through a new marriage[16] or de facto marital union[17]. If there are assets, it is called a solemn inventory of assets; if there are no assets, it is called a declaration of non-existence. The procedure itself consists of appointing a lawyer (special guardian) to represent the minor children of the person who is getting married or being united. The lawyer who, by means of a public deed acting on behalf of the minors, will carry out the inventory of the assets or will declare the non-existence of the assets. Note: If the minor is a common child of the couple who intend to marry or declare a common-law marriage, neither the inventory nor the declaration of non-existence of the assets is required.
