No domestic life insurance company shall make any disbursement unless the same is evidenced by a voucher correctly describing the consideration for the payment. If the expenditure is for both services and disbursements, the voucher shall set forth the services rendered and an itemized statement of the disbursements made. If the expenditure is in connection with any matter pending before any legislative or public body, or before any department or officer of any state or government, the voucher shall correctly describe, in addition, the nature of the matter and of the interest of such company therein. When such voucher cannot be obtained, the expenditure shall be evidenced by an affidavit describing the character and object of the expenditure and stating the reason for not obtaining such voucher.
