La. Civ. Code art. 718
Current with operative changes from the 2024 Third Special Legislative Session
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.
