S.D. Codified Laws § 43-30 app. 5-01
Recitals as to the marital status of parties to the instrument, or as to the homestead status of the property, or as to the identity of parties named in instruments in the chain of title, in any conveyance or other instrument affecting title to real estate in this state, which has been, or hereafter shall be, recorded in the office of the register of deeds for the county in which the land is situated, or the record of the instrument, or a certified copy of the record, shall be prima facie evidence of the truth of such recitals.
When a conveyance has been recorded and no spouse has joined therein, evidence should be required that the grantor was unmarried at the time of the execution of the conveyance or if married, that the premises conveyed did not constitute the grantor's homestead and that neither the grantor nor any member of the grantor's family reside thereon should be considered sufficient evidence.
The evidence may consist of an affidavit by any person, including the grantor or grantee or an affidavit pursuant to the Marketable Record Title Act, SDCL Ch. 43-30.
