The person shall be exempted from the obligation of restitution, who, believing in good faith that the payment was made on the account of a legitimate and existing credit, should destroy the title or should allow the action to prescribe, or should abandon the pledges or cancel the guaranties of his right. A person who has unduly made a payment may only address himself to the true debtor or to the sureties with regard to whom the action may still be in force.
