What is the effect of acknowledgement on the period of limitation? How is this period of limitation computed in such a case?
Effect of Acknowledgement on the Period of Limitation
The Limitation Act, 1963 proceeds on the general principle that once a cause of action accrues, the prescribed period begins to run, and it runs continuously until it expires. But this general rule admits of important exceptions — one of the most significant being the doctrine of acknowledgement embodied in Section 18. When a person who is liable, within the running period of limitation, voluntarily acknowledges that liability in writing, the law treats that acknowledgement as the starting point of a fresh period. The previous running of time is, in effect, set aside. A new period — identical in length to the original prescribed period — begins from the date of the acknowledgement, and the creditor is restored to the position he would have been in had the cause of action just then accrued.
The rationale is deeply rooted in good conscience: a party who, by his own voluntary written admission, has recognised a subsisting liability and thereby induced the other side to refrain from immediate legal action, cannot then be heard to say that the period has expired. To permit such an inconsistency would be to allow a person to take advantage of his own conduct — a result that the law has always refused to countenance.
The Statutory Provision: Section 18
Section 18(1) of the Limitation Act, 1963 provides:
"Where, before the expiration of the prescribed period, an acknowledgment of liability in respect of any property or right has been made in writing signed by the party against whom such property or right is claimed, a fresh period of limitation shall be computed from the time when the acknowledgment was so signed."
Section 18(2) provides:
"Where the writing containing the acknowledgment is undated, oral evidence may be given of the time when it was signed; but, subject to the provisions of the Indian Evidence Act, 1872, oral evidence of its contents shall not be received."
The Explanation to Section 18 then clarifies four matters:
(a) An acknowledgment may be sufficient even though it be accompanied by a refusal to pay, or is qualified, or is made subject to condition.
(b) An acknowledgment of one of several joint contractors (debtors) shall bind all the joint contractors (debtors).
(c) An acknowledgment by one of several co-trustees shall bind all the co-trustees.
(d) An acknowledgment by the borrower of a time-barred debt shall not constitute a valid acknowledgment.
The Effect: A Fresh Period of Limitation
The primary legal consequence of a valid acknowledgement under Section 18 is the computation of a fresh period of limitation from the time when the acknowledgement was signed. This means:
The entire period that had already run before the acknowledgement is disregarded — it is treated as spent, but the clock is reset from the date of acknowledgement.
A full fresh period — identical in duration to the original prescribed period for the suit — begins to run from the date of the acknowledgement.
If a second acknowledgement is made within that fresh period, the period is refreshed again from the date of the second acknowledgement. There is no theoretical limit to how many times successive acknowledgements may refresh the period.
The fresh period that commences after acknowledgement is the same prescribed period applicable to the suit — not a shorter or different period.
The Supreme Court in Shapoor Freedom Mazda v. Durga Prosad Chamaria (AIR 1961 SC 1236) settled authoritatively that a fresh period of limitation under Section 18 is equivalent in every respect to the original prescribed period — the nature of the right, and therefore the period applicable to it, does not change merely because it is being computed from a date of acknowledgement rather than from the original accrual of the cause of action.
How the Fresh Period Is Computed
The computation of the fresh period under Section 18 follows a straightforward method, but several important rules govern it:
Step 1 — Verify that the acknowledgement was made before the expiry of the prescribed period. This is the foundational condition. If the acknowledgement was made even one day after the period expired, it is of no legal effect. Section 18 is explicit: the acknowledgement must be made "before the expiration of the prescribed period." Clause (d) of the Explanation reinforces this by stating that an acknowledgement of a time-barred debt shall not constitute a valid acknowledgement.
Step 2 — Identify the date on which the acknowledgement was signed. The fresh period runs from this date. Where the writing is undated, Section 18(2) permits oral evidence to be given of the time when it was signed. The contents of the acknowledgement, however, must be proved from the document itself — oral evidence of the contents is not admissible.
Step 3 — Compute the full prescribed period from the date of acknowledgement. The fresh period is not a partial or abbreviated period — it is the same full period that would have applied had the cause of action just accrued on the date of the acknowledgement.
Step 4 — Apply the ordinary rules of computation to the fresh period. The rules of Section 12 — exclusion of the starting day — apply to the computation of the fresh period just as they apply to the computation of the original period.
Step 5 — Check for successive acknowledgements. If a second acknowledgement is made within the fresh period computed from the first, the period is again refreshed from the date of the second acknowledgement.
Conditions for a Valid Acknowledgement
The benefit of Section 18 is not available merely on the assertion that an acknowledgement was made. The courts have identified with precision the conditions that must be satisfied.
Writing and Signature
The acknowledgement must be in writing and must be signed by the party against whom the right is claimed, or by his authorised agent. An oral admission, however clear and unambiguous, is entirely outside the scope of Section 18. The writing requirement serves the essential purpose of certainty and prevents disputes about the fact and terms of the acknowledgement.
An agent's authority to acknowledge need not be expressed in a formal power of attorney — it may be implied from the circumstances of the case or from the nature of the agent's employment. A manager of a business running its day-to-day accounts is ordinarily presumed to have such authority. A pleader, by contrast, has no implied authority by virtue merely of his retainer to make an acknowledgement that would create a fresh period of limitation against his client.
Made Before Expiry of the Prescribed Period
This requirement is absolute and non-negotiable. The Supreme Court and the High Courts have consistently held that an acknowledgement after the expiry of the period is of no avail — it cannot resurrect a right that has already been extinguished or a remedy that has already been barred.
Acknowledgement of a Subsisting Liability
Clause (d) of the Explanation makes explicit what was always implicit in the section: an acknowledgement of a time-barred debt does not constitute a valid acknowledgement. The doctrine operates on living rights — it can refresh a period that is still running, not restore one that has already expired.
Acknowledgement Must Relate to the Same Right
The acknowledgement must pertain to the very right or property in respect of which the suit is filed. An acknowledgement of one transaction does not operate as an acknowledgement of a different claim between the same parties. A general reference to "our accounts" without specifying the nature of the liability has been held insufficient.
Sufficient Acknowledgement: The Standard
The single most litigated aspect of Section 18 is the standard of sufficiency. The courts have consistently held that the acknowledgement need not be express, formal, or technically worded. The test is whether, from the writing as a whole, a jural relationship — the existence of the liability — can be reasonably inferred. The Supreme Court in Shapoor Freedom Mazda v. Durga Prosad Chamaria (AIR 1961 SC 1236) laid down the governing standard: the statement must be clear and unambiguous — if the writing is reasonably capable of being construed as denying the liability, it cannot serve as an acknowledgement. But the acknowledgement is sufficient if it admits a subsisting jural relationship from which the liability can be inferred, even without an express promise to pay.
In Lakshmiratan Cotton Mills Co. Ltd. v. J.K. Jute Mills Co. Ltd. (AIR 1957 All 311), the court held that an unconditional admission of the account, even if accompanied by a request for time to pay, constitutes a valid acknowledgement. In Venkatlal G. Pittie v. Bright Bros. (P) Ltd. (AIR 1987 SC 1939), the Supreme Court held that where the writing refers only generally to accounts between parties without specifically acknowledging the debt sued on, it does not constitute an acknowledgement within Section 18.
The Explanation: Qualified and Conditional Acknowledgements
The Explanation draws out a principle of liberality in construing acknowledgements. An acknowledgement is sufficient even where it is:
Accompanied by a refusal to pay — "I owe you the money but I will not pay" is still a valid acknowledgement.
Qualified — subject to reservations or conditions.
Made subject to a condition — such as "subject to final audit" or "subject to settlement of disputes."
The courts have however maintained that where the qualification amounts to a complete denial of the existence of any liability — rather than merely a dispute about quantum or a refusal to pay — the document is not an acknowledgement at all. The qualification must be one that leaves the existence of the liability open — it must not negate it.
Joint Debtors and Co-Trustees
The Explanation contains two rules of binding effect that deserve particular attention in practice.
Joint Debtors: An acknowledgement by one of several joint debtors binds all the joint debtors. A fresh period of limitation computed from the acknowledgement of one runs against all. The rationale is the principle of joint and several liability: each joint debtor has authority, implied from the nature of the relationship, to bind the others in acknowledging the common debt. This is particularly significant in partnerships — where the acknowledgement of one partner during the subsistence of the firm binds the firm and all its partners.
Co-Trustees: Similarly, the acknowledgement of one co-trustee binds all co-trustees. Where property is held by multiple trustees and one trustee acknowledges the trust's liability to a beneficiary within the running period, the fresh period of limitation runs against all the trustees from the date of that acknowledgement.
Illustrations
Illustration I — Simple Written Acknowledgement
A lends Rs. 10,00,000 to B on 1 January 2020. The prescribed period for a money suit is three years — expiring 1 January 2023. On 1 November 2022 — within the running period — B writes a signed letter to A: "I acknowledge that I owe you Rs. 10,00,000 on account of the loan of January 2020 and request you to give me three more months to arrange payment."
This is a valid acknowledgement under Section 18. The fresh period of three years is computed from 1 November 2022 — the date the acknowledgement was signed. A must now file his suit by 1 November 2025.
Illustration II — Acknowledgement with Refusal to Pay
On the same facts, suppose B's letter states: "I acknowledge that I owe you Rs. 10,00,000 but I decline to pay, as I believe you have wronged me in another matter and I intend to set off those claims."
Under clause (a) of the Explanation, an acknowledgement is sufficient even though accompanied by a refusal to pay. The acknowledgement is valid. A fresh period of three years runs from the date of B's letter. The set-off claim does not negate the acknowledgement — it merely raises a defence on the merits.
Illustration III — Acknowledgement After Expiry: No Effect
A lends money to C on 1 January 2018. The three-year period expires on 1 January 2021. On 15 March 2021 — after the period has expired — C writes to A acknowledging the debt and promising to pay. This acknowledgement is wholly ineffective. The period had already expired before the acknowledgement was made. Clause (d) of the Explanation is decisive: an acknowledgement of a time-barred debt shall not constitute a valid acknowledgement. A's suit is barred.
Illustration IV — Successive Acknowledgements: Computation
A lends money to D on 1 January 2018. The three-year period would expire 1 January 2021.
First Acknowledgement: D signs a written acknowledgement on 1 December 2020 — within the period. A fresh three-year period runs from 1 December 2020, expiring 1 December 2023.
Second Acknowledgement: D makes a second written acknowledgement on 1 November 2023 — within the fresh period. A further three-year period runs from 1 November 2023, expiring 1 November 2026.
A files suit in June 2026 — within the second fresh period. The suit is within time.
Illustration V — Acknowledgement by One of Several Joint Debtors
E, F, and G are jointly and severally liable to H for a loan taken on 1 January 2020. The three-year period expires on 1 January 2023. On 1 June 2022, E alone signs a written letter to H acknowledging the joint debt. Under the Explanation, this acknowledgement by E binds all three — E, F, and G. A fresh period of three years runs against all three from 1 June 2022. H must file suit by 1 June 2025.
Illustration VI — Qualified Acknowledgement
A commercial firm receives a balance confirmation letter from its debtor stating: "We confirm that the balance in your favour as on 31 March 2023 stands at Rs. 8,00,000 subject to audit."
The words "subject to audit" are a qualification — not a denial. The acknowledgement is valid under clause (a) of the Explanation, and a fresh period of limitation runs from the date of that letter.
Section 18 Distinguished from Section 19
Section 18 — which deals with acknowledgement — operates on the same foundational principle as Section 19, which deals with part payment. Both create a fresh period of limitation, and both require that the act be done before the expiry of the prescribed period. The distinction lies in the nature of the act:
Feature | Section 18 — Acknowledgement | Section 19 — Part Payment |
|---|---|---|
Nature of act | Written admission of liability | Actual payment on account of the debt |
Form required | In writing, signed | Payment itself is sufficient; no writing required |
By whom | Party or authorised agent | Party liable or authorised agent |
Effect | Fresh period from date of acknowledgement | Fresh period from date of payment |
Time-barred debt | Acknowledgement of time-barred debt invalid | Payment of time-barred debt also cannot revive it |
Both sections are tools of refreshment — they restore the creditor's remedy within the running period, not after it.
The Underlying Principle
Section 18 stands as a legislative recognition of the principle of honest dealing in legal relationships. The law of limitation is designed to compel diligence and protect defendants from stale claims. But where the defendant has, by his own voluntary written conduct, removed the very basis for the staleness plea — where he has reassured the creditor within the running period that the liability is alive and recognised — the law refuses to permit him to then invoke limitation as a shield. The acknowledgement carries its own legal consequence: a fresh start, a renewed period, and a restored right to seek justice. This is not indulgence — it is the law giving effect to the legitimate expectations that a written acknowledgement, honestly made, reasonably creates.
