Fees on documents inadvertently received.

5. Fees on documents inadvertently received.—When a document on which the whole or any part of the fee prescribed by this Act has not been paid is produced or has, through mistake or inadvertence, been received in any Court or public office, the Court or the head of the office may, in its or his discretion at any time, allow the person by whom such fee is payable or any interested party to pay the fee or part thereof as the case may be, within such time as may be fixed; and upon such payment, the document shall have the same force and effect as if the full fee had been paid in the first instance.
