A promissory note is a written and signed promise to pay a fixed sum of money to a named person or the bearer, either on demand or by a set date. So, what is promissory note, exactly? It is one of the simplest legal instruments used in personal loans, business borrowing and informal lending across India. This piece covers its meaning, format, real examples and legal validity, in about 5 minutes.
QUICK STAT
Under the Negotiable Instruments Act, 1881, Section 4, a promissory note is an instrument in writing containing an unconditional undertaking, signed by the maker, to pay a certain sum to a specific person or the bearer. (Source: Negotiable Instruments Act, 1881 (India Code))
Understanding what is promissory note turns a verbal promise into written, legally recognised proof. Without one, a lender has little to fall back on if repayment stops. With one, both sides have written evidence of the amount, the terms and the signature. Banks, NBFCs and digital lenders often use a promissory note for payment alongside a formal loan agreement to reinforce the borrower’s obligation.
A promissory note is not one-size-fits-all. A demand promissory note is payable whenever the payee asks for it, common in informal family or friend loans. A time promissory note fixes a specific repayment date or instalment schedule, which is how most personal loans and NBFC lending structure their promise note to pay arrangements. Knowing which type you are signing changes when your obligation actually falls due.
Once you know what is promissory note in principle, the process itself is simple.
PRO TIP
Digital lending platforms and NBFCs now generate an e-signed promissory note for payment as part of the loan bundle, using Aadhaar-based e-sign, so borrowers rarely draft one from scratch. This digital workflow still carries the same legal weight as a paper note, provided the e-sign method meets the Information Technology Act’s requirements.
| Instrument | Parties Involved | Nature |
|---|---|---|
| Promissory Note | Maker and payee (2 parties) | Unconditional promise to pay |
| Bill of Exchange | Drawer, drawee and payee (3 parties) | Order to pay, not a promise |
| Cheque | Drawer, bank and payee | Bill of exchange drawn on a bank, payable on demand |
Ajay, a 29-year-old marketing executive in Pune, borrows ₹1,50,000 from a friend for a medical emergency. They sign a promissory note to pay ₹1,50,000 at 10% simple interest, in six monthly instalments of ₹27,500, stamped as per Maharashtra’s rules.
Neha runs a small boutique in Jaipur and takes a ₹75,000 advance from a supplier as working capital. Instead of a verbal understanding, the supplier asks for a promise note to pay the amount back within 90 days, which protects both sides if the boutique’s sales are slower than expected.
Ankit borrows ₹40,000 from his uncle to cover admission fees. A simple demand promissory note, signed by both and witnessed by a family member, means the uncle can ask for repayment whenever needed, with no fixed due date.
WATCH OUT
A promissory note is usually less detailed than a full loan agreement, since it skips collateral or dispute clauses. If unstamped, it may not be admissible as evidence. Stamp duty itself varies sharply by state. Maharashtra and Karnataka, for instance, charge a nominal fixed duty on notes below a threshold, while some states apply a percentage of the loan value above certain limits, so it is worth checking your specific state’s schedule before relying on one for a large amount. It also depends entirely on the borrower’s ability to repay.
A promissory note is legally enforceable in India provided it meets the Negotiable Instruments Act, 1881 and is stamped per the relevant state rules. Courts have consistently upheld properly executed notes as valid evidence of debt. Lenders, including regulated entities that follow RBI guidance on fair lending, often combine a promissory note for payment with a broader loan agreement for larger personal loans, since NBFC digital lending workflows typically layer both documents for stronger protection. For high-value borrowing, consult a legal professional before signing.
