Louisiana Civil Code Tit. IX, Art. 2701. Call in warranty

The lessor is bound to take all steps necessary to protect the lessee's possession against any disturbance covered by Article 2700 as soon as the lessor is informed of such a disturbance. If the lessor fails to do so, the lessee may, without prejudice to his rights against the lessor, file any appropriate action against the person who caused the disturbance.

If a third person brings against the lessee an action asserting a right in the thing or contesting the lessee's right to possess it, the lessee may join the lessor as a party to the action and shall be dismissed from the action, if the lessee so demands.
