The payments made by the council from the borough funds must be made by proper borough orders, drawn upon the treasurer. No borough order may be authorized by council or signed by the president or secretary of a council unless there are sufficient funds in the treasury of the borough to pay the order, and no orders may be made payable at any time in the future or draw interest. A separate borough order must be drawn for each account or payment.
