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.
