JM 3-8.600
In accordance with 31 U.S.C. § 3324, prohibiting advance payments of public monies, no disposition of funds should be made for services rendered, purchases made, etc., until the transaction has been accomplished. An exception to this rule is permitted if advance payment is authorized by “other law.” This provision has been interpreted to include state law. Therefore, if state law requires the advance payment of filing fees, for instance, such payments may be issued upon appropriate showing of the requirement of law. A voucher prepared for issuance of an advance payment should specifically identify the statute requiring payment in advance.
