S.D. Codified Laws § 21-19-2
No levy shall be made on any homestead to reach the valuation thereof in excess of the homestead exemption set by subdivision 43-45-3(2), whether on attachment, execution, or other process, except as provided in this section. In the event the creditor claims such valuation exceeds such exemption he shall deliver to the officer holding the process, an affidavit, by himself or his attorney, setting forth the legal description of such homestead if real property, or the descriptive data contained on the certificate of title if a mobile home, the claim as to valuation thereof, and all encumbrances according to the affiant's best knowledge, information, and belief. If it appears from such affidavit that the value of debtor's equity exceeds such homestead exemption, the officer must file in the office of the register of deeds of the county where the homestead is situated, a notice of levy on such homestead with the said affidavit attached thereto, which notice and affidavit shall be duly recorded and shall be forthwith served upon the debtor in the same manner as provided by this code as to other notices. From the time of such filing and such service, such notice shall be effective as a levy only on the excess over and above the homestead exemption.
