Effect of Acknowledgment in Writing (Section 18) →

Section 18 of the Limitation Act, 1963 is the great extender. The law of limitation bars a stale remedy, but it does not punish a creditor whose debtor has, in writing, admitted that the debt is still owed. Where a party against whom a right is claimed acknowledges the liability in writing, signed, before the prescribed period runs out, the section directs that a fresh period of limitation shall be computed from the date the acknowledgment was signed. The clock does not merely pause — it resets to zero and runs the full original length again. For a judiciary or CLAT-PG aspirant, Section 18 is among the most heavily examined provisions in the entire Act, because it sits at the intersection of limitation, contract and evidence, and because the leading authorities draw a series of fine distinctions that examiners love.

This chapter sets out the statutory text, the doctrinal foundation supplied by Khan Bahadur Shapoor Fredoom Mazda v. Durga Prosad Chamaria, the five conditions of a valid acknowledgment, the rule that an acknowledgment need not amount to a promise to pay, the cardinal limit that it must precede the expiry of the running period, the modern application to balance sheets under the Insolvency and Bankruptcy Code, and the careful line between Section 18 and a fresh promise to pay a time-barred debt under Section 25(3) of the Indian Contract Act. For the place of this section in the broader scheme, see our introduction to the Limitation Act and the chapter on the bar of limitation under Section 3.

Statutory anchor — the text of Section 18

Section 18 occupies the part of the Act dealing with the effect of death, fraud and acknowledgment on the computation of the period of limitation. It works alongside the general rules on computation of the period of limitation under Sections 12 to 24. The provision reads:

The Explanation supplies three clarifications: an acknowledgment may be sufficient though it omits to specify the exact nature of the property or right, or avers that the time for payment has not yet come, or is accompanied by a refusal to pay, or is coupled with a claim to set-off, or is addressed to a person other than the person entitled; the word "signed" means signed personally or by a duly authorised agent; and an application for the execution of a decree shall not be deemed to be an application in respect of any property or right.

Why acknowledgment extends time

The rationale flows from the very nature of limitation. As the chapter on the bar of limitation explains, the Limitation Act bars the remedy but does not extinguish the right — the principle the Supreme Court articulated in Bombay Dyeing & Mfg. Co. Ltd. v. State of Bombay, AIR 1958 SC 328, where the Court held that when a debt becomes time-barred it does not become extinguished but only unenforceable in a court of law. The right survives; only the remedy is withdrawn after a certain lapse of time. Where the debtor, while the remedy is still alive, admits in writing that the liability subsists, the law treats that admission as a fresh starting point. The creditor who held a live but unasserted claim is given a fresh full period within which to sue, because the debtor's own conduct has reaffirmed the relationship.

It is important to grasp what Section 18 does not do. It does not create a new cause of action, and it does not create a new debt. It works only on the limitation; the underlying obligation is the same obligation that existed before. The acknowledgment is merely a peg on which a new period of limitation is hung. This is why the section is universally described as one that "extends" or "renews" limitation, never one that revives an extinguished right.

The four essential conditions

Distilled from the statutory language, four conditions must coincide for Section 18 to operate. First, there must be an acknowledgment of liability in respect of the property or right claimed. Second, the acknowledgment must be in writing and signed — personally or by a duly authorised agent — by the party against whom the right is claimed, or by a person through whom he derives his title or liability. Third, the acknowledgment must be made before the expiration of the prescribed period of limitation. Fourth, it must relate to a present, subsisting liability and indicate an intention to admit the jural relationship between the parties. If any one of these is absent, the section does not apply and the original limitation runs unaffected.

Each of these conditions has generated its own jurisprudence. The first and fourth — what amounts to an acknowledgment of a subsisting liability — are the most litigated, and the Supreme Court's exposition in Shapoor Mazda is the master authority. The third — the timing — produces the sharp rule that a barred liability cannot be revived, settled in Sampuran Singh v. Niranjan Kaur. The second — the signature and agency — turns on the Explanation and on the evidentiary rules in sub-section (2).

A present, subsisting liability

The acknowledgment must be of an existing liability. A bare admission of a past transaction, or a statement that some dealing once took place, is not enough; the writing must admit that the liability still subsists at the time of the admission. The acknowledgment must involve an admission of a subsisting relationship of debtor and creditor, and an intention to continue that relationship until it is lawfully determined must be apparent. The Madras High Court in Subbaraya v. Narasimha, AIR 1936 Mad 939, made the foundational point that an acknowledgment within the section need not contain a promise to pay, nor amount to a promise to pay — it is the admission of subsisting liability, not the undertaking to discharge it, that the section requires.

The acknowledgment must relate to a definite liability in respect of the right claimed. A statement so vague that it cannot be connected to the particular right asserted will not serve. But the section is generous in one respect: by Explanation (a), an acknowledgment is good even if it omits to specify the exact nature of the property or right. The admission may be implied from the language and from the surrounding circumstances; it need not be express. The court reads the document as a whole and in its context, applying a liberal but principled construction.

The Shapoor Mazda five-point test

The leading authority on what constitutes a valid acknowledgment is Khan Bahadur Shapoor Fredoom Mazda v. Durga Prosad Chamaria, AIR 1961 SC 1236, decided under Section 19 of the Limitation Act, 1908 (the predecessor of the present Section 18). Justice Gajendragadkar, speaking for the Supreme Court, distilled the requirements of a valid acknowledgment into a set of propositions that every examinee should be able to reproduce.

1. The statement on which a plea of acknowledgment is founded must relate to a present, subsisting liability, though the exact nature or the specific character of the said liability may not be indicated in words.
2. The words used must indicate the existence of a jural relationship between the parties — such as that of debtor and creditor — and it must appear that the statement is made with the intention to admit that jural relationship.
3. The intention to admit the jural relationship may be inferred by implication from the nature of the admission, and need not be expressed in words.
4. Where a statement is relied on as an acknowledgment, the words have to be construed in the context and the circumstances in which they were used; the court may, for that purpose, consider the surrounding circumstances and even oral evidence (subject to the bar in sub-section (2) on proving the contents of the writing by oral evidence).
5. A liberal construction should be placed on the words used; but the court must not travel beyond the statement to import an admission of liability where none is reasonably borne out by the language.

The Court emphasised that the admission need not be express, but must be of a present subsisting liability; a statement which merely refers to a past liability, or which is consistent with the liability having been discharged, will not do. This five-point structure is the spine of every answer on Section 18.

Intention to admit the jural relationship

The requirement that the writing indicate an intention to admit the jural relationship is the filter that separates a true acknowledgment from a mere narrative reference. The point was decisively applied in Tilak Ram v. Nathu, AIR 1967 SC 935. There the plaintiffs, suing for redemption of mortgaged lands, relied on four statements which they alleged were acknowledgments under Section 19 of the 1908 Act. The Supreme Court held that statements which merely describe the existence of a mortgagor-mortgagee relationship, without expressly or by necessary implication admitting a subsisting liability or the right to redeem, do not constitute valid acknowledgments. A reference to the relationship is not an admission of the relationship's continuing legal force.

The lesson of Tilak Ram is that the court looks for an admission of a subsisting right or liability made with the intention to admit it. A recital in a document, an incidental mention in correspondence, or a statement consistent with the liability having ended will not pass. The acknowledgment must, in substance, say: the relationship still binds us. Where the words are equivocal, the liberal construction enjoined by Shapoor Mazda applies — but liberal construction cannot manufacture an intention that the language does not bear.

Need not be a promise to pay

A recurring confusion is between an acknowledgment under Section 18 and a promise to pay. The two are distinct. An acknowledgment need not be, and need not contain, any promise to pay. The Supreme Court in Lakshmiratan Cotton Mills Co. Ltd. v. Aluminium Corporation of India Ltd., AIR 1971 SC 1482, held that the statement on which the plea of acknowledgment is founded must relate to a subsisting liability, but it need not amount to a promise to pay; an acknowledgment does not create a new right of action, it merely extends the period of limitation. In that case a letter from the company's Secretary-cum-Chief Accountant, written in the course of a prolonged reconciliation of accounts, was held to admit the debtor-creditor relationship — the company disputed only the amount, not the liability — and so qualified as an acknowledgment by a duly authorised agent.

Explanation (a) reinforces the point from the other direction. An acknowledgment remains sufficient even though it is accompanied by a refusal to pay, or coupled with a claim to set-off, or avers that the time for payment has not yet come. In other words, a debtor may admit the liability and in the same breath decline to pay, plead a set-off, or assert that payment is not yet due — and the admission still restarts the clock. What matters is the admission of the subsisting liability, not the willingness to discharge it.

The acknowledgment must precede expiry

This is the cardinal temporal rule, and the most frequently tested. Section 18 operates only where the acknowledgment is made before the prescribed period has expired. An acknowledgment of a liability that is already time-barred is of no effect — it cannot create a fresh period of limitation, because there is no live limitation left to extend. The Supreme Court settled this in Sampuran Singh v. Niranjan Kaur, AIR 1999 SC 1047. The case concerned redemption of an oral mortgage of 1893; the Court held that an acknowledgment, if any, has to be prior to the expiration of the prescribed period for filing the suit, and that an acknowledgment of liability made after the prescribed period has expired does not revive the period of limitation. Because the sixty-year redemption period had already run out, no subsequent acknowledgment could save the suit.

The practical corollary is the doctrine of successive acknowledgments. So long as each acknowledgment is made while a limitation period is still running, a fresh period starts from each. A chain of valid acknowledgments — each before the running period expires — can keep a claim alive indefinitely. But the instant a gap opens up in which the period expires without a fresh acknowledgment, the claim dies, and nothing the debtor writes thereafter can resurrect it under Section 18. Aspirants should hold this contrast firmly: an acknowledgment within time renews; an acknowledgment after time is a nullity for the purposes of this section.

Signature and the authorised agent

An acknowledgment without a signature is no acknowledgment at all. The writing must be signed by the party against whom the right is claimed, or by a person through whom he derives his title or liability, or by a duly authorised agent. Explanation (b) makes clear that "signed" means signed either personally or by an agent duly authorised in this behalf. The signature need not be that of the debtor himself; the signature of his agent suffices, and the agent's authority may be established by a power of attorney or gathered from the surrounding circumstances, as Lakshmiratan Cotton Mills illustrates, where the authority of the Secretary-cum-Chief Accountant to acknowledge on the company's behalf was inferred from the conduct of the company's affairs.

The person acknowledging must be one who has personal liability to pay, or who stands in the chain of title or liability — a stranger's admission cannot bind the debtor. Section 20 of the Act supplements Section 18 here: it provides that, in the case of a person under disability, the expression "agent duly authorised" includes his lawful guardian, committee or manager; and that, in general, one of several joint contractors, partners, executors or mortgagees is not made chargeable merely by the acknowledgment of another. The interaction with payment is governed separately by Section 19 and its companion rules on the effect of payment on account of a debt or of interest.

Form of the writing and the Explanation

The acknowledgment must be in writing, but the Act prescribes no particular form. It may be contained in a letter, an account, a balance sheet, a deposition, a recital in a deed, or any other signed writing, provided it admits a subsisting liability. Where the writing is undated, sub-section (2) permits oral evidence of the time when it was signed — a necessary concession, since the section turns on whether the signing preceded the expiry of limitation. But oral evidence of the contents of the writing is not received, subject to the provisions of the Indian Evidence Act, 1872. The acknowledgment must be proved by the document itself, not by testimony of what it said.

By Explanation (a), the acknowledgment need not specify the exact nature of the property or right; it may be addressed to a person other than the person entitled to the property or right; and it remains good though accompanied by a refusal to pay or a claim to set-off. This breadth means that the court will not reject an otherwise valid admission on technical grounds of form or address. The substance — an admission of subsisting liability, signed, in time — is what controls.

Balance sheets and the IBC

The most important modern application of Section 18 concerns the balance sheets of companies. The Supreme Court in Asset Reconstruction Company (India) Ltd. v. Bishal Jaiswal, (2021) 6 SCC 366, held that entries in the balance sheet of a corporate debtor, prepared and signed in accordance with the Companies Act, can amount to an acknowledgment of liability under Section 18, giving rise to a fresh period of limitation. Crucially, the Court held that Section 18 of the Limitation Act applies to proceedings under the Insolvency and Bankruptcy Code, 2016, so that a financial creditor may rely on the corporate debtor's balance-sheet entries to bring a Section 7 application within the renewed period of limitation.

The Court was careful to qualify the proposition. Not every entry in a balance sheet automatically amounts to an acknowledgment; the entry must be read in the context in which it occurs and in the light of any notes annexed to the balance sheet and any qualification by the auditors. Where a note or disclaimer indicates that the company disputes the liability, the entry may not amount to an admission. The acknowledgment, in short, must still satisfy the Shapoor Mazda requirement of an intention to admit a subsisting liability — the balance-sheet context supplies the writing and the signature, but the substance of admission is examined on ordinary principles.

Acknowledgment distinguished from Section 25(3)

A favourite examination contrast is between Section 18 of the Limitation Act and Section 25(3) of the Indian Contract Act, 1872. The two are fundamentally different in mechanism. Section 18 operates on a live limitation: a written, signed admission of subsisting liability, made before the period expires, gives a fresh period. It does not create a new contract; it extends the limitation on the existing obligation. Section 25(3), by contrast, operates on a dead claim: a written and signed promise to pay a debt of which the creditor might have enforced payment but for the law of limitation is a good contract without consideration. A time-barred debt cannot be acknowledged into life under Section 18 — but a fresh written promise to pay it is enforceable as a new contract under Section 25(3).

The distinctions to carry into the hall are crisp. Under Section 18, the writing must be made before limitation expires; under Section 25(3), it is made after the debt is already barred. Under Section 18, what is required is an admission of liability — no promise to pay is needed; under Section 25(3), an express promise to pay is the very thing required. Under Section 18, the effect is to extend the limitation on an existing right; under Section 25(3), the effect is to create a fresh, independent and enforceable promise. The two provisions are not alternatives at the same moment in time — they apply at opposite ends of the limitation period.

Exclusions — execution and collateral use

Two further points round out the topic. First, Section 18 does not apply to applications for the execution of a decree. Explanation (c) expressly provides that an application for the execution of a decree or order shall not be deemed to be an application in respect of any property or right. The consequence is that an acknowledgment cannot extend the period for execution; even in the case of a consent decree for specific performance of a contract, the execution has to be filed within the period prescribed by Article 136 of the Schedule — twelve years from the date the decree becomes enforceable — and no acknowledgment will enlarge it. The effect of acknowledgment or payment by another person in execution is instead governed by the specialised rules in Section 20.

Second, an unregistered document whose registration is compulsory may nonetheless be used for the collateral purpose of proving an acknowledgment of liability under Section 18. The bar on receiving an unregistered compulsorily-registrable document in evidence does not prevent its use to establish the fact of acknowledgment, because that is a collateral and not a primary use of the instrument. This is a useful point where the acknowledgment is embedded in a deed that was never registered.

MCQ angle — the recurring distinctions

Several propositions recur in prelims with high frequency. First, the effect of a valid acknowledgment is a fresh period of limitation from the date of signing — not a mere extension by some fixed number of days, and not the creation of a new debt. Second, the acknowledgment must be made before the prescribed period expires; an acknowledgment of a time-barred liability is a nullity under Section 18 — the Sampuran Singh rule. Third, an acknowledgment need not amount to a promise to pay — the Lakshmiratan Cotton Mills and Subbaraya rule, reinforced by Explanation (a), which preserves the acknowledgment even where coupled with a refusal to pay.

Two further distinctions are worth carrying forward. The Shapoor Mazda five-point test — present subsisting liability, jural relationship, intention to admit, construction in context, and liberal but bounded interpretation — is the master statement and is frequently tested verbatim. And the contrast with Section 25(3) of the Contract Act — before expiry versus after expiry, admission versus promise, extension versus new contract — is the classic two-statute distinction. For the broader machinery within which Section 18 sits, revisit the Limitation Act hub, the chapter on computation of the period of limitation, and the related rules on the effect of payment on account of a debt or interest.
