No contract or agreement or other obligation involving the expenditure of money in excess of $100.00 shall be entered into unless the finance director shall first certify to the city commission or to the proper officer, as the case may be, 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, and a copy of such certificate shall be filed and immediately recorded by the finance director. The sum so certified shall not thereafter be considered unencumbered until the city is discharged from such contract, agreement or obligation. The provisions of this section shall not apply to contracts or proceedings relating to improvements any part of the cost of which is to be paid by special assessments.
