Conveyance and Mortgage of Immovables – Quitclaim deed
Art. 2443. Purchase of a thing already owned. A person cannot purchase a thing he already owns. Nevertheless, the owner of a thing may purchase the rights of a person who has, or may have, an adverse claim to the thing.
Art. 2500. Eviction, definition, scope of warranty. The seller warrants the buyer against eviction, which is the buyer’s loss of, or danger of losing, the whole or part of the thing sold because of a third person’s right that existed at the time of the sale. The warranty also covers encumbrances on the thing that were not declared at the time of the sale, with the exception of apparent servitudes and natural and legal non-apparent servitudes, which need not be declared. If the right of the third person is perfected only after the sale through the negligence of the buyer, though it arises from facts that took place before, the buyer has no claim in warranty.
Art. 2502. Transfer of rights to a thing. A person may transfer to another whatever rights to a thing he may then have, without warranting the existence of any such rights. In such a case the transferor does not owe restitution of the price to the transferee in case of eviction, nor may that transfer be rescinded for lesion. Such a transfer does not give rise to a presumption of bad faith on the part of the transferee and is a just title for the purposes of acquisitive prescription. If the transferor acquires ownership of the thing after having transferred his rights to it, the after-acquired title of the transferor does not inure to the benefit of the transferee.
