1501. The alienation in perpetuity of immovable property for an annual rent, is equivalent to a sale. It is subject to the same rules as the contract of sale in so far as they can be made to apply.
1502. The rent may be payable either in money or in kind. Its nature and the rules to which it is subject are stated in the articles relating to rents contained in the Second Chapter of the First Book of the Second Part.
1503. The obligation to pay the rent is a personal liability; the purchaser is not discharged from it by abandonment of the property, nor is he discharged by reason of the destruction of the property by a fortuitous event.
1504. Exchange is a contract by which each party gives to the other one thing for another.
It is effected in the same manner as sale.
1505. If one of the parties to the exchange, even after having received the thing given to him or her, prove that the other party was not owner of it, he or she cannot be compelled to deliver that which he or she has promised, but only to return that which he or she has received.
1506. The party who is evicted from what he or she has received in exchange has the option of demanding damages or of recovering what he or she has given.
1507. The rules contained in the Book respecting Sale apply equally to exchange, when not inconsistent with any article of this title.
