A negotiable instrument is a document guaranteeing the payment of a specific amount of money, either on demand, or at a set time, whose payer is usually named on the document. More specifically, it is a document contemplated by or consisting of a contract, which promises the payment of money without condition, which may be paid either on demand or at a future date. The term has different meanings, depending on its use in the application of different laws and depending on countries and contexts. The word "negotiable" refers to transferability, and "instrument" refers to a document giving legal effect by the virtue of the law.
