S.D. Codified Laws § 29A-5-410
Except as otherwise provided in this chapter or as ordered by the court for good cause shown, notice of hearing on a petition for an order subsequent to the appointment of a guardian or conservator, including an order approving a guardian's report or conservator's accounting, shall be mailed to the minor, if age ten or older, to the protected person, to their attorneys of record, if any, to the relatives of the minor or protected person who would then be entitled to notice of an original petition to appoint, to any facility that is responsible for the care or custody of the minor or protected person, to the guardian or conservator, if the guardian or conservator is not the petitioner, and to such other individuals or entities as the court may order. Unless otherwise ordered by the court, the notice shall be mailed at least fourteen days prior to the hearing and shall be accompanied by a copy of the petition or other document. A minor or protected person may not waive compliance with this section, and the court may not dispense with notice to a minor or protected person unless the minor or protected person is an absentee or the court is reasonably satisfied that such notice will likely cause significant harm to the minor or protected person and the court's finding is supported by a written report of a physician, psychiatrist or licensed psychologist. If deceased, notice to a minor or protected person shall be sent to his last known address or to his successors in interest.
