S.D. Codified Laws § 21-19-5
The notice of levy provided by § 21-19-3 shall not be essential to the validity of any levy, and any levy made without giving such notice shall be valid and shall have full force and effect except as otherwise specifically provided in this section, but the time in which a debtor or any dependent of a debtor may make claim of exemptions as provided in § 21-19-9, shall not commence to run unless and until such notice is given, and in the absence of such notice such claim may be made by such debtor or dependent at any time within ninety days of actual knowledge of such levy, or thereafter by permission of the court, if the court finds there was reasonable excuse for not making such claim within such ninety days. In the event any such claim is made in a case where no notice has been given under § 21-19-3 the court must require any property set aside to the debtor as exempt or its fair value to be restored by the creditor to the debtor.
