S.D. Codified Laws § 10-25-12
Any deed acquired pursuant to § 10-25-39.1 or 10-25-39.2 vests in the grantee an absolute estate in fee simple in the real property. However, the real property is subject to any claim that the state may have in the real property for taxes, liens, or encumbrances. The real property is also subject to any lien for past-due installments of special assessments for the financing of municipal improvements levied pursuant to chapter 9-43, including principal and interest on the installments except as provided by § 9-43-100. The holder of the deed or the holder's successor in interest is entitled to immediate exclusive possession of the real property described in the deed regardless of the rights of any person to redeem or question exclusive possession thereafter.
