S.D. Codified Laws § 43-31-10
If any court by order has reserved a homestead according to law for the use, occupancy, or possession of any surviving minor children of a decedent, or any minor, such court may, during the minority of such minor, on the filing of an application by any person interested in the property, or any guardian ad litem of the minor, or any conservator of the minor, requesting a change of homestead and setting forth facts sufficient to show that such action by the court would be to the best interest and benefit to such minor, change the limits of the homestead by changing the metes and bounds, as well as the record of the description, or may change it entirely. The application shall be heard by the court issuing the original order upon such notice as the court shall deem necessary; but such changes shall not prejudice conveyances or liens made or created previously thereto.
