S.D. Codified Laws § 26-7A-55
If all necessary parties admit the allegations contained in the petition and the court accepts the admissions, the court may find, conclude and make a decision as to adjudication of the child under the applicable provisions of chapter 26-8A, 26-8B, or 26-8C. The court may then proceed with the dispositional phase of the proceedings without conducting a formal adjudicatory hearing on the petition with the concurrence of all parties. However, at the request of any party or if required by the court, the court shall set a later time and date for the dispositional hearing. The court shall then determine interim dispositional arrangements concerning the child and the parties.
If the petition is not admitted by all necessary parties, including the child, if appropriate, or if the petition is denied by any necessary party or the child, if appropriate, the court shall proceed with the adjudicatory hearing on the petition, if notice has been given as required by § 26-7A-15.1, if applicable, or schedule the adjudicatory hearing for a later time and date.
If the advisory hearing is adjourned and continued or if the advisory hearing is completed and the adjudicatory hearing on the petition is scheduled for a later time and date, the court shall make an interim order regarding temporary custody of the child as determined by the court.
