Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. The papers set the promissory note problem almost every year: “A signs: I promise to pay B or order Rs. 2,000. Is it a valid promissory note?” Answer it by running through the seven essentials of s.4 one by one, then check s.31 of the RBI Act and stamping. The illustrations to s.4 decide most variations.

1. Meaning and kinds

The Negotiable Instruments Act, 1881 does not define the idea; it lists the instruments. Section 13(1): a “negotiable instrument” means a promissory note, bill of exchange or cheque payable either to order or to bearer. An instrument is payable to order if it is expressed to be so payable, or payable to a particular person without words prohibiting transfer; it is payable to bearer if expressed to be so payable or if the only or last indorsement is in blank (Explanations (i) and (ii)).

Besides the three statutory instruments, others are negotiable by custom or usage: hundis (whose local usages s.1 saves), bank drafts (s.85A deals with them), treasury bills, dividend and interest warrants, and bearer debentures. Documents such as fixed deposit receipts, postal orders, share certificates and bills of lading are not negotiable instruments, though some are transferable.

3. Promissory note

Section 4: a promissory note is an instrument in writing (not being a bank-note or a currency-note) containing an unconditional undertaking, signed by the maker, to pay a certain sum of money only to, or to the order of, a certain person, or to the bearer of the instrument.

The essentials, each with the illustration that tests it:

Section 31(2) of the RBI Act, 1934 adds a public law condition: no person other than the RBI or the Central Government may make or issue a promissory note payable to bearer. A note payable to bearer made by a private person is therefore invalid, and making it is an offence. Bank notes and currency notes are excluded from s.4 for the same reason.

A promissory note must also be stamped under the applicable Stamp Act (in Karnataka, the Karnataka Stamp Act, 1957); an unstamped note is inadmissible in evidence, but the underlying debt may still be proved independently. A note payable on demand, or with no time for payment stated, is payable on demand (s.19).

4. Bill of exchange

Section 5: a bill of exchange is an instrument in writing containing an unconditional order, signed by the maker, directing a certain person to pay a certain sum of money only to, or to the order of, a certain person or to the bearer of the instrument.

5. Cheque

Section 6: a cheque is a bill of exchange drawn on a specified banker and not expressed to be payable otherwise than on demand, and it includes the electronic image of a truncated cheque and a cheque in the electronic form (inserted by the Negotiable Instruments (Amendment and Miscellaneous Provisions) Act, 2002). A truncated cheque is one whose physical movement is stopped in the clearing cycle and replaced by an electronic image, which is how cheques are cleared today under the Cheque Truncation System.

So every cheque is a bill of exchange, with two special features: the drawee is always a banker, and it is always payable on demand.

7. Problem

‘A’ signs an instrument as follows: “I promise to pay ‘Y’ on order Rs. 1,00,000/-.” Is it a valid promissory note? (January 2026; the June 2025 paper set the same problem as “I promise to pay B or order Rs. 2,000.”)

Issue. Whether the instrument satisfies s.4 and is not barred by s.31 of the RBI Act.

Law. Section 4 requires a written, unconditional undertaking, signed by the maker, to pay a certain sum of money only, to or to the order of a certain person or to bearer. Illustration (a), “I promise to pay B or order Rs. 500”, is a promissory note. Section 19 makes an instrument with no time of payment payable on demand. Section 31 of the RBI Act forbids a note payable to bearer.

Application. The instrument is in writing and signed by A. It contains a promise (“I promise to pay”), not a mere acknowledgement. The promise is subject to no condition. The sum, ₹1,00,000, is certain and is money only. The payee, Y, is a certain person. The words “on order” are best read as “or order”, making the note payable to Y or as Y directs, which is exactly illustration (a). Even if read literally as “on order” (pay when Y asks), the note simply becomes payable on demand under s.19, which does not affect its validity. It is not payable to bearer, so s.31 of the RBI Act is not attracted.

Conclusion. It is a valid promissory note, enforceable once duly stamped. The same reasoning gives the same answer for “I promise to pay B or order Rs. 2,000.” If the words had been “I promise to pay bearer Rs. 1,00,000”, the instrument would satisfy s.4 but be void under s.31(2) of the RBI Act.

How this is examined

“Define promissory note. Explain essentials of promissory note” and “Define negotiable instrument. Explain characteristics of negotiable instruments” (January 2026); “Define cheque. How is it different from bill of exchange and promissory note?” (August 2024). The promissory note problem is set in nearly every paper. Use the illustrations to s.4 by letter; they are the authority the examiner expects.
