Louisiana Civil Code Tit. IV, Art. 718. Partition by licitation

If the estate is partitioned by licitation and the co-owner who consented to the establishment of the predial servitude acquires the ownership of the whole, the servitude burdens the entire estate as if the co-owner had always been sole owner. If the entire estate is adjudicated to any other person the right granted by the co-owner is extinguished.
