S.D. Codified Laws § 21-18-35
When the answer of the garnishee shall disclose that any other person than the defendant claims the indebtedness or property in his hands, and the name and residence of such claimant, the court may on motion order that such claimant be made a defendant to the garnishee action; and that notice thereof, setting forth the facts, with a copy of such order, in such form as the court shall direct, be served upon him, and that after such service shall have been made, the garnishee may pay or deliver to the officer or the clerk such indebtedness or property, and have a receipt therefor, which shall be a complete discharge from all liability to any party for the amount so paid or property so delivered. Such notice shall be served in the manner required for service of a summons in a civil action, and may be made without the state or by publication thereof if the order shall so direct.
