In any proceeding in any court in this state, by executors or administrators, for the sale of lands of deceased persons, or by guardians, for the sale of lands of their wards, or for partition of lands, when such lands are to be sold in parcels, or actual partition thereof shall be made, it shall be competent for the court to order such executor or administrator, guardian, or other officer or person authorized to sell the lands in question in any such proceeding, or commissioners authorized to make partition of such lands, to cause such lands to be surveyed and subdivided, and a map or plat of the same to be made, showing the lots or parcels of such subdivisions or partition designated by numbers; which map or plat shall be acknowledged by the person or persons so causing the same to be made, in like manner as is now required by law in cases of plats or maps made for owners of land, and shall, in like manner, be certified by the Registered Land Surveyor making the same; and the certificate shall contain, among other things, an accurate and definite description of the lands so subdivided or partitioned. Such map or plat shall be submitted to the court for its approval and, if approved by the court, shall be recorded in the recorder's office of the county or counties in which the lands in question in any such proceeding are situated.
