S.D. Codified Laws § 15-26A-35
Except when the undertaking is with a corporate surety, an undertaking upon an appeal shall be of no effect unless it be accompanied by the affidavit of the sureties, in which each surety shall state that he is worth a certain sum mentioned in such affidavit, over and above all his debts and liabilities, in property within this state not by law exempt from execution, and which sum so sworn to by such sureties shall in the aggregate, be double the amount specified in such undertaking. An appellee may, however, except to the sufficiency of the sureties by service of exception upon appellant within ten days after filing of the bond. Appellant, within the next ten days and upon at least four days' notice to adverse parties, shall produce before the circuit court the sureties who thereupon may be examined on oath by adverse parties as to their sufficiency in such manner as the circuit court deems proper. If the circuit court finds the personal sureties sufficient, it shall endorse its allowance upon the undertakings and cause them to be filed with the clerk. The costs of the justification shall be paid by appellant if the sureties are found insufficient, but if found sufficient, the party or parties excepting to the sureties shall pay the costs of the justification. Unless the sureties justify as so prescribed within the allotted time, the appeal shall be regarded as if no undertaking had been given.
