The institution of civil law functions with notions from which it itself is formed. Among the main notions of civil law that need to be regulated is that of patrimony. Patrimony is a distinct legal institution that represents the totality or universality of patrimonial rights and patrimonial obligations that belong to a person. Heritage is a legal concept that expresses the set of rights and obligations of a person as a universality, as a totality independent of the goods that the heritage includes at a given moment; whether we regard it as an entity closely related to the person of the subject or whether a universality of rights necessarily exists for any subject of law (even when the passive exceeds the active); it can never be alienated but can be transmitted to the death of the subject at the moment when its will, which gives it the character of unity, is extinguished. The patrimony includes tangible and intangible assets, consumable or fungible, movable or immovable, principal and accessory assets, etc. That is, everything that represents the powers, faculties, The patrimony fulfills three functions, essential in their importance: the patrimony constitutes the general pledge of the creditors, realizes the real subrogation with universal title and makes possible the universal and universal transmission of rights and obligations.
