S.D. Codified Laws § 8-10-18
Every warrant for the payment of money issued by any township, which is not registered because of lack of funds with which to pay such warrant, shall be countersigned by the treasurer of such township, who shall also endorse on such warrant an order to the depository, by which such warrant is to be paid, to pay such warrant to the order of the payee and charge the same to the account of such treasurer. Such warrant so countersigned and endorsed shall have the same force and effect as a check drawn by said treasurer upon such depository. No such warrant shall be paid by the depository unless so countersigned and endorsed by such treasurer. No warrant shall be countersigned by the treasurer so long as there are any registered warrants outstanding.
