Usufruct

In civil law

The right of enjoying a thing the property of which is vested in another, and to draw from the same all the profit, utility, and advantage which it may produce, provided it be without altering the substance of the thing. Perfect usufruct is of things which the usufructuary can enjoy without altering their substance, though their substance may be diminished or deteriorated naturally by time or by the use to which they are applied; as, a house, a piece of land, animals, furniture, and other movable effects. Imperfect or quasi usufruct is of things whicii would be useless to the usufructuary if he did not consume and expend them or change the substance of them; as, money, grain, liquors. In this case, the alteration may take place. Civ. Code La. art.
