Whether you’re lending money to a friend, a relative, or a business contact, a properly drafted loan agreement is the single best protection you can put in place before handing over the money — not after a dispute already exists. Here’s exactly what to include, and the specific legal detail that trips up more people than anything else: getting it validly stamped.
Cover the amount, interest, repayment schedule, and default consequences clearly — vague terms are exactly what cause disputes later, so precision here is worth the extra time.
Stamp duty for loan agreements and promissory notes varies by state — check your specific state’s Stamp Act rules, since this isn’t uniform across India.
This is the step people skip most often, and it’s genuinely critical — under Section 35 of the Indian Stamp Act, an insufficiently stamped promissory note is inadmissible as evidence in court, and unlike most other documents, this defect generally cannot be cured later by simply paying a penalty.
Both parties should sign, ideally with at least two independent witnesses who also sign — this strengthens the document’s evidentiary value if its authenticity is ever disputed.
While not always mandatory, registering the agreement with the Sub-Registrar adds an extra layer of legal certainty and public record for larger loan amounts.
The stamping requirement deserves real emphasis because the consequences of getting it wrong are unusually harsh compared to other documents. For most instruments, an unstamped or under-stamped document can still be admitted into evidence if you pay the duty plus a penalty at the time of the dispute. Promissory notes and bills of exchange are specifically carved out from this leniency — courts have held an unstamped promissory note simply cannot be used to prove the debt, full stop, and this defect is generally treated as incurable.
It’s also worth deciding upfront whether your document is a “promissory note” (a simple, unconditional promise to pay) or a more detailed “loan agreement” (which can include conditions, schedules, and other terms) — these can attract different stamp duty treatment depending on your state, and a lawyer can help you draft the version that best balances simplicity with the protections you want.
Given the stakes, here’s how a promissory note and a fuller loan agreement actually compare:
| Document Type | Best For |
|---|---|
| Simple Promissory Note | Straightforward loans with a clear single repayment date — quick to draft, but strict stamping rules apply |
| Detailed Loan Agreement | Larger amounts, installment schedules, interest, or other specific conditions — more comprehensive protection |
Stamp duty is typically paid through your state’s designated stamp vendors, e-stamping portals (available in many states now), or at the Sub-Registrar’s office — check your specific state’s process, since procedures do vary.
Stamp duty itself is usually a modest amount for typical personal loan sizes, calculated per your state’s specific rate schedule. Registration, if you choose to do it, carries its own separate fee. Having a lawyer draft the agreement costs more than a template, but significantly reduces the risk of gaps that cause problems later.
For a simple, modest loan between people who trust each other, a carefully written and properly stamped agreement using a good template can work. For larger amounts, business loans, or anything with more complex terms, a lawyer’s review is a worthwhile investment relative to what’s at stake if a dispute arises later.

Yes, in most cases — proper stamping is the critical requirement for admissibility as evidence; registration adds extra security but isn’t always mandatory depending on the amount and your state’s rules.
For small, simple loans, a good template can work, provided you still get it properly stamped — but a lawyer’s review is worth it for anything beyond a straightforward personal loan.
Get it stamped as soon as possible — while promissory notes specifically have a strict, generally incurable rule, some other loan agreement formats may have more flexibility for late stamping with a penalty, so consult a lawyer promptly about your specific document type.
Yes — each party should retain a signed original or a certified copy, since you may need to produce it as evidence later.
Yes — a jurisdiction clause specifying which court will hear disputes is a useful, enforceable addition, and can save argument later about where to file.
There’s no single universal cap on personal loan interest rates in India, though excessively high rates can be challenged as unconscionable — a reasonable, clearly stated rate is always the safer choice.
A handwritten agreement can be valid, provided it’s clear, signed, and properly stamped — typed documents are generally easier to read and less prone to disputes about legibility, but aren’t legally required.
It can feel awkward, but a simple, properly stamped agreement protects both people and often prevents exactly the kind of misunderstanding that damages family relationships when memories of the terms later diverge.
