All warrants drawn upon the municipal treasury must be signed by the Chairperson of the Board and countersigned by the Municipal Clerk, stating the particular fund to which the warrant is chargeable, the person to whom it is payable, and the purpose of the expenditure. No money shall be otherwise paid than upon warrants so drawn. Each warrant shall specify the amount included in the adopted budget statement for the fund upon which it is drawn, and the amount already expended of such fund.
