No contract, agreement, or other obligation involving the expenditure of money shall be entered into, nor shall any ordinance, resolution, or order for the expenditure of money be passed, or issued, by Council, or be authorized by any officer of the Municipality unless the Director of Finance shall have certified in writing that the money required for such contract, agreement, obligation or expenditure is in the Treasury to the credit of the fund from which it is to be drawn and not appropriated for any other purpose.  The provisions of this section shall not be construed to prevent the making of contracts for a period extending beyond a single fiscal year, when such contracts are otherwise authorized by the Constitution of the State of Ohio, by this Charter, or by general laws of the State of Ohio.  All moneys actually in the Treasury to the credit of the fund from which they are to be drawn and all moneys applicable to the payment of the obligation or appropriation involved that are anticipated to come into the Treasury before the maturity of such contract, agreement, or obligation from taxes, assessments, license fees or from the sales of service, products, or byproducts of any Municipal undertaking, and moneys derived from lawfully authorized bonds or notes shall for the purpose of certification be deemed to be in the Treasury to the credit of the appropriate fund, and shall be subject to such certification.
