The right route depends almost entirely on what paperwork you have. Choose it deliberately, because the wrong forum costs years.
Start here
A legal notice setting out the debt, the basis, the amount, and a deadline. It is not legally compulsory for most claims but it does three useful things: it produces payment in a large number of cases, it fixes the date of demand for interest, and it becomes evidence of the acknowledgement or refusal.
The routes
- Summary suit under Order 37 CPC. Available on bills of exchange, hundis, promissory notes, and suits on a written contract, an enactment, or a guarantee for a debt. Its power is that the defendant cannot defend as of right; they must apply for leave to defend, and leave is refused where there is no genuine triable issue. This is by far the strongest civil route if your claim is documented.
- Section 138 NI Act, if a cheque was issued and dishonoured. Criminal pressure plus interim compensation of up to 20 percent under Section 143A.
- MSME Samadhaan, if you are a registered micro or small enterprise supplying goods or services. Compound interest at three times the RBI bank rate and a fast statutory route.
- Arbitration, if the contract has a clause. Often faster than a suit, though the fees are your own.
- Insolvency under the IBC, where the debtor is a company and the default is at least one crore rupees. A powerful lever, but it is not a recovery mechanism and should not be used purely as one.
- Ordinary civil suit, where the claim is undocumented and needs evidence.
Under the Limitation Act, 1963, the ordinary period for a suit for money is three years from when the amount became due. A written, signed acknowledgement of the debt before the period expires starts a fresh three years under Section 18, and part payment has a similar effect under Section 19. Get an acknowledgement in writing every year on a long-running dues account. This one habit saves more claims than any other.
Winning is not the same as recovering
A decree is only useful if it can be executed. Before you sue, ask what you will attach: bank accounts, salary, immovable property, receivables. Ask for an attachment before judgment where there is a real risk of the assets disappearing, because after the decree is often too late.
