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the transferor does not owe restitution of the price to the transferee in case of eviction, nor may that transfer be rescinded for lesion.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.
