Things and Ownership – Protection of ownership
Art. 526. Recognition of ownership; recovery of the thing. The owner of a thing is entitled to recover it from anyone who possesses or detains it without right and to obtain judgment recognizing his ownership and ordering delivery of the thing to him.
Art. 530. Presumption of ownership of movable. The possessor of a corporeal movable is presumed to be its owner. The previous possessor of a corporeal movable is presumed to have been its owner during the period of his possession. These presumptions do not avail against a previous possessor who was dispossessed as a result of loss or theft.
Art. 531. Proof of ownership of immovable. One who claims the ownership of an immovable against another in possession must prove that he has acquired ownership from a previous owner or by acquisitive prescription. If neither party is in possession, he need only prove a better title.
