All disbursements of funds in the custody and control of the local agency shall be by check, except for items of a petty cash nature which may be made in cash (see § 1642-2.5, infra). No check shall be issued except in payment of an accounts payable voucher duly executed and approved, and properly supported (see § 1642-2.4 below). The opening of the bank accounts, the numbering of checks, check signing and bank reconciliations have been described in Subpart 1642-1. Checks, when issued, shall be recorded in the cash disbursements-voucher register (see § 1642-3.3). Space should be reserved on the face of the check to give the invoice number and other data which will enable the creditor to identify the payment.
