The Free (Legal) Dictionary
n. check, promissory note, bill of exchange, security, or any document representing money payable which can be transferred to another by handing it over (delivery) and/or endorsing it (signing one's name on the back either with no instructions or directing it to another such as "pay to the order of Pamela Townsend.")
A negotiable instrument is a specialized type of contract for the payment of money that is unconditional and capable of transfer by negotiation. As payment of money is promised later, the instrument itself can be used by the holder in due course frequently as money. Common examples include cheques, banknotes (paper money), and commercial paper. In the United States, the Article 3 of the Uniform Commercial Code covers the use of negotiable instruments except banknotes (money).
