Lending ₹20,000, or ₹20 lakh, to a friend or relative in India isn't just a handshake transaction. The Reserve Bank of India estimates that informal lending in India exceeds ₹14 lakh crore annually, and a large slice of that travels through WhatsApp messages, verbal promises, and tea-shop conversations that turn into disputes the moment repayment falters.
If you're about to lend or borrow privately, this is the 2026 guide you actually need: what's legal, what's documented, what's taxable, and what gets you to court the fastest if things go sideways.
The three laws every private lender in India should know
1. The Indian Contract Act, 1872. Section 25 establishes that a loan with consideration (the principal amount) creates an enforceable contract. A promise to repay, in writing, is binding even between family members. Verbal agreements over ₹100 are technically enforceable too, they're just much harder to prove.
2. The Negotiable Instruments Act, 1881. Section 4 defines a promissory note as an unconditional written promise by the maker to pay a certain sum to a payee. Once stamped properly, a pro note is one of the strongest civil debt instruments available, and Section 138 makes a bounced repayment cheque a criminal offence.
3. State Money-Lending Acts. If you lend as a business, repeatedly, to multiple unrelated borrowers, charging interest, you need a state-issued money-lender's licence. In Maharashtra, that's the Maharashtra Money-Lending (Regulation) Act, 2014. A one-off loan to a friend is exempt; lending to fifteen Vashi residents this year is not.
Documented vs informal: the practical difference
A documented loan can be recovered in 6–18 months through a civil court (or 90 days under Order 37 CPC summary procedure if the debt is liquidated and undisputed). An undocumented cash loan, even with screenshot evidence, often takes 3–5 years to recover, and recovery rates fall below 20% past two years from the default date.
Promissory note vs loan agreement: which to use
| Use case | Best document |
|---|---|
| One-time, fixed-amount, single-borrower loan | Promissory note (cheap, fast, NI Act protections) |
| Multi-instalment, with interest, custom terms (collateral, prepayment, default clauses) | Loan agreement (Contract Act, fully tailored) |
| Loan within family with no interest, < ₹50,000 | Simple acknowledgment letter (still on paper) |
Both should be stamped in the state where the agreement is executed. In Maharashtra, e-stamping via the IGR Maharashtra portal takes ten minutes and removes the most common challenge in court: "the document isn't properly stamped, your honour."
The hard tax limits
The Income Tax Act has three rules every private lender in India must memorise:
- Section 269SS, No cash loan above ₹20,000. Use account-payee cheque, bank transfer, or UPI. Cash loans over the threshold attract a 100% penalty under Section 271D.
- Section 269T, Same limit on repayment of loans over ₹20,000. Always repay through bank transfer; never accept cash repayment over the threshold.
- Interest income is taxable. Money your friend pays you back at the same amount you lent? Not taxable. The ₹15,000/year interest he pays on a ₹2 lakh loan? Taxable as "income from other sources", declare it in Schedule OS of your ITR.
The 7-step documentation checklist
- Identify both parties properly: full legal name, PAN, address, mobile, photo ID copy.
- Define the principal exactly: "₹3,00,000 (Rupees Three Lakh only)".
- State the interest in clear terms: rate, type (flat or reducing), and start date.
- Set the repayment schedule: instalment amounts, frequency, due dates, or lump-sum date.
- Specify the default clause: penalty interest rate, grace period, recovery jurisdiction (the city's civil court).
- Get the e-stamp at the value mandated by your state's Bombay/Indian Stamp Act schedule.
- Sign in front of two witnesses; keep one original each + a notarised copy if the loan is ≥ ₹5,00,000.
When the old way fails
The most common defence by a defaulting borrower in India is "it was a gift, not a loan". A WhatsApp message saying "I'll return it next month" defeats that argument in court. A signed, stamped, witnessed agreement defeats it in fifteen minutes.
Modern platforms, like the one running on lendastra.com, handle the seven steps above as a guided flow: KYC, agreement generation, stamp-duty calculation, e-signature, and a repayment tracker, without you ever opening Word or visiting a lawyer's office.
Three things to do today if you've already lent informally
- Get it in writing now. A delayed acknowledgment letter, signed by the borrower, dated today, stating the amount and original loan date, is far better than nothing. Stamped, even better.
- Move repayments to bank transfer. Even if the original loan was in cash, switch all instalments to UPI or RTGS so you have an audit trail.
- Set up a quarterly check-in. Most informal-loan defaults start with a missed conversation, not a missed payment. A calendar reminder solves more lending disputes than a lawyer's notice ever will.
The Indian legal system rewards documentation. The ten minutes it takes to do it right at the start is the cheapest insurance you'll ever buy on a friendship.
