S.D. Codified Laws § 43-30 app. 15-17
A foreign personal representative appointed in testacy must be appointed by an order or statement from a South Dakota court or clerk, qualify and be issued letters in order to transfer title to the real estate. If no local administration or application or petition therefor is pending in this state, a foreign personal representative appointed in intestacy may file certified copies of the foreign documents of appointment and of any official bond with the clerk of courts in a county in which property belonging to the decedent is located and thereafter be authorized to transfer title to real property in South Dakota with the same authority as a locally appointed personal representative. However, a bank or trust company shall not have the authority to act unless qualified to do trust business or exercise trust powers in this state.
