Commonwealth Consolidated Acts Commonwealth Consolidated Acts(1) Where a simple signature on a blank stamped paper stamped with an impress duty stamp is delivered by the signer in order that it may be converted into a bill, it operates as a prima facie authority to fill it up as a complete bill for any amount the stamp will cover, using the signature for that of the drawer or the acceptor or an indorser.
(2) And in like manner when a bill is wanting in any material particular, the person in possession of it has a prima facie authority to fill up the omission in any way he or she thinks fit.
(3) In order that any such instrument when completed may be enforceable against any person who became a party thereto prior to its completion, it must be filled up within a reasonable time, and strictly in accordance with the authority given. Reasonable time for this purpose is a question of fact:
Provided that, if any such instrument after completion is negotiated to a holder in due course, it shall be valid and effectual for all purposes in his or her hands, and he or she may enforce it as if it had been filled up within a reasonable time and strictly in accordance with the authority given.
(4) For the purposes of subsection ( 1) of this section, duty stamp includes a duty stamp, required, by the law of the State in which the instrument is issued, to be impressed on a bill.
