Explainer · Civil Procedure · Limitation
Section 18 of the Limitation Act, 1963 lets a debt get a fresh start: if the debtor admits the liability in a signed writing before the limitation period runs out, a new limitation period begins from the date of that acknowledgement. This is one of the most useful tools for a creditor, and one of the most common traps for a debtor. This explainer sets out what counts as an acknowledgement, the strict conditions, and how courts read it. Last verified October 2026.
- What it does: under Section 18 of the Limitation Act, 1963, a signed written acknowledgement of liability starts a fresh limitation period.
- Timing: it must be made before the existing period expires; it cannot revive a claim that is already time-barred.
- Form: it must be in writing and signed by the party liable or his authorised agent, and admit a present liability.
- Fresh period: the new limitation runs from the date the acknowledgement is signed.
01The problem: a debt running out of time
A simple money debt must usually be sued on within three years. Creditors often extend time informally, wait for promised payments, or accept partial payments, and then find the three years have quietly passed. On a strict reading, the claim is then barred, even though the debtor still owes the money and may even admit it.
Section 18 is the answer. If, within the running period, the debtor acknowledges the liability in writing, the clock resets. A fresh period starts from the date of that acknowledgement. This keeps a genuine, admitted debt alive, and it is why creditors push for written confirmations such as balance confirmations and signed statements of account.
02What Section 18 says
Section 18 provides that where, before the expiration of the prescribed period for a suit or application, a party against whom the right is claimed makes an acknowledgement of liability in writing, signed by him or by his duly authorised agent, a fresh period of limitation is computed from the time when the acknowledgement was so signed.
Two sub-rules follow. The signing of an undated writing may be proved by oral evidence of the time when it was signed, but oral evidence of its contents is not allowed (Section 18(2)). An acknowledgement may be sufficient even if it omits to specify the exact nature of the liability, or is coupled with a refusal to pay, or is addressed to a person other than the person entitled to the right.
It resets, it does not revive
Section 18 starts a fresh period only if the acknowledgement is made while limitation is still running. Once the period has already expired, an acknowledgement cannot revive a dead claim.
03The conditions for a valid acknowledgement
Courts insist on each of these:
- Before expiry: the acknowledgement must be made before the prescribed period runs out. Timing is everything.
- In writing: an oral admission does not count.
- Signed: it must be signed by the party liable, or by his duly authorised agent.
- An existing liability: there must be an admission of a subsisting jural relationship, that is, a present liability, not merely a past transaction.
Section 18 resets the limitation clock only if the admission is in writing, signed, and made before the period expires. It cannot revive a claim that is already time-barred.
The admission need not state the exact amount, and it can be read with the surrounding documents. But the intention to admit a present liability must appear. The exact starting point of the new period is the date of signing. For the wider set of periods this interacts with, see limitation periods for common suits and appeals.
04What counts as an acknowledgement
Courts have accepted a range of documents as valid acknowledgements, provided they admit a present liability:
- a signed balance confirmation or statement of account;
- an entry in the debtor’s own signed books of account;
- a letter admitting the debt, even if it refuses to pay for now;
- a balance sheet of a company, signed and approved, that shows the amount as owing (as courts have held in several cases).
What does not count is a bare reference to a past dealing with no admission of present liability, an unsigned document, or anything made after the period has expired. The Supreme Court has also held that an acknowledgement of only part of a claim extends limitation only for that acknowledged part, not for the whole claim.
05Related routes: part payment and promises
Section 18 is not the only way to extend time. Under Section 19, where part of a debt or interest is paid before the period expires, and the payment is recorded in the handwriting of, or in a writing signed by, the person making it, a fresh period runs from the date of the payment. This is a sister provision often used alongside Section 18.
A separate route is a fresh promise to pay a time-barred debt under Section 25(3) of the Indian Contract Act, 1872. That is different from Section 18: it can create a new enforceable obligation even after the old debt is barred, if the promise is in writing and signed. Section 18, by contrast, only resets limitation on a debt that is still alive.

08Frequently asked questions
What is acknowledgement of debt under Section 18?
It is a signed writing, made before the limitation period expires, in which the debtor admits a present liability. Under Section 18 of the Limitation Act, 1963, it starts a fresh period of limitation computed from the date the acknowledgement is signed.
Can an acknowledgement revive a time-barred debt?
No. Section 18 only resets the clock if the acknowledgement is made while limitation is still running. Once the period has expired, an acknowledgement cannot revive the claim. A separate written and signed promise under Section 25(3) of the Contract Act can, however, create a fresh obligation.
Does the acknowledgement have to state the exact amount?
No. The admission need not specify the exact nature or amount of the liability, and it can even be coupled with a refusal to pay. What matters is that it admits a present, subsisting liability and is in writing and signed before the period expires.
Can a company balance sheet be an acknowledgement?
Courts have held that a signed and approved balance sheet showing a sum as owing can amount to an acknowledgement under Section 18, depending on the facts and any notes to the accounts. The document must admit a present liability.
What is the difference between Section 18 and part payment under Section 19?
Section 18 is about a written acknowledgement of liability. Section 19 is about part payment of a debt or interest before the period expires, recorded in the payer’s handwriting or signed writing. Both start a fresh period, from the date of the acknowledgement or the payment respectively.
Can I research acknowledgement disputes in Claw?
Yes. Claw lets you track cases, orders and hearings at the relevant court or forum across 9,102 benches and forums, and search 30 crore+ judgments in under 5 seconds. It tracks and researches the matter but does not give legal advice.
