La. Civ. Code art. 2701
Current with operative changes from the 2024 Third Special Legislative Session
The lessor is bound to take all steps necessary to protect the lessee's possession against any disturbance covered by the preceding Article, 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 party 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.
