Louisiana Civil Code Tit. XXV, Art. 3506. General definitions of terms

(1) Assignment. An assignment is a transfer of rights by particular title, such as by sale, donation, or particular legacy.

(2) Juridical act. A juridical act is a manifestation of will intended to produce legal consequences. Juridical acts may be unilateral, such as donations mortis causa, or bilateral, such as contracts.

(3) Successor. A successor is a person who takes the place of another. There are two kinds of successors: the universal successor, such as the heir, universal legatee, and general legatee; and the particular successor, such as the buyer, donee, or particular legatee. The universal successor represents the person of the deceased and succeeds to his rights and charges. The particular successor succeeds only to the rights appertaining to the thing that is sold, donated, or bequeathed, or otherwise transferred to him.

(4) Third person. A third person is a person who is not a party to a ceremony, an instrument, a juridical act, a judgment, or a legal relationship. Examples of third persons include officiants to ceremonies, witnesses to instruments or juridical acts, and all those other than obligor and obligee to the legal relationship between the former and the latter. With respect to an obligation, a third person does not include a person such as a universal successor or a person who assumes the obligation or is bound by contract to recognize it.
