In case of the death of any landowner, or the determination of his interest, between the date of the provisional order and the completion of the improvements sanctioned thereby, the right to complete such improvements, and to assign the title to an absolute charge, shall pass to the succeeding landowner; but if the succeeding landowner shall not within three calendar months after his succession proceed with the works, so as to complete the same in conformity with the provisional order, the preceding landowner, or in case of his decease his executors or administrators, may complete such improvements, and shall become entitled to have the absolute charge executed to him or them. If the succeeding landowner shall complete the improvements there shall be distinct absolute charges executed to such landowner, and the the preceding landowner or his personal representatives, for the outlay made by the preceding and succeeding landowners respectively, and in case of difference the Commissioners shall determine the proportions; provided that the succeeding landowner may, with the sanction of the Inclosure Commissioners, and after notice to the parties to whom notice was originally given, or such of them as may be living, and such other persons, if any, as the Commissioners may direct, terminate the proceedings under the provisional order, on payment of the outlay and expenses made thereunder, and indemnifying the person to whom the title to the absolute charge may have been assigned. Notwithstanding the foregoing provisions, if the title to an absolute charge shall have been assigned by the preceding landowner, the assignee may complete the improvements if he shall proceed therewith within one calendar month from the time the preceding landowner ceased to be such landowner.
