Negotiable instruments

A negotiable instrument is a document guaranteeing the payment of a specific amount of money, either on demand, or at a set time, with the payer 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 can have different meanings, depending on what law is being applied and what country it is used in and what context it is used in.

Examples of negotiable instruments include promissory notes, bills of exchange, banknotes, demand draft and cheques.

Because money is promised to be paid, the instrument itself can be used by the holder in due course as a store of value. The instrument may be transferred to a third party; it is the holder of the instrument who will ultimately get paid by the payer on the instrument. Transfers can happen at less than the face value of the instrument and this is known as discounting; e.g., this may happen if there is doubt about the payer's ability to pay.

In the Commonwealth of Nations almost all jurisdictions have codified the law relating to negotiable instruments in a Bills of Exchange Act, e.g. Bills of Exchange Act 1882 in the UK, Bills of Exchange Act 1908 in New Zealand, Bills of Exchange Act 1909 in Australia, the Negotiable Instruments Act, 1881 in India and the Bills of Exchange Act 1914 in Mauritius. The Bills of Exchange Act:

Additionally most Commonwealth jurisdictions have separate Cheques Acts providing for additional protections for bankers collecting unendorsed or irregularly endorsed cheques, providing that cheques that are crossed and marked 'not negotiable' or similar are not transferable, and providing for electronic presentation of cheques in inter-bank cheque clearing systems.

Common prototypes of bills of exchanges and promissory notes originated in China, where special instruments called feitsyan were used to safely transfer money over long distances during the reign of the Tang Dynasty in the 8th century.
