Whenever any conservator sells any real estate belonging to his protectee, under an order of court, he shall report the sale to the court ordering the sale, within the same time and in the same manner as personal representatives are required by law to report sales of real estate made by them for the payment of debts. The report shall remain on file ten days before being acted upon and shall be proceeded upon as in the case of sales of real estate by a personal representative. Any sale, if approved by the court, is valid to all intents and purposes. If the court refuses to approve the report, the order of sale may be renewed, and the same proceedings shall be had as upon the original order.
