Discharge of Contract by Lapse of Time and Operation of Law

Updated 10 October 2026 · Fact-checked

Discharge by lapse of time means a contract can no longer be enforced in court because the limitation period has expired. Discharge by operation of law means the law itself ends the contract, through death, insolvency, merger, unauthorised material alteration or similar events. Identify the event, then match it to the correct category.

Understand Discharge by Lapse of Time and Operation of Law

A contract is discharged when the rights and duties under it come to an end. Most contracts end by performance. Some end without either party choosing to end them. These are lapse of time and operation of law.

Lapse of time: The Limitation Act, 1963 fixes the period within which you must sue. If you do not sue within that period, the remedy in court is barred. The debt or promise is not wiped out in every sense, but you cannot enforce it by suit. For an ordinary money claim on a contract, the period is generally three years from when the right to sue arises. Exams use this general three-year period. Treat it as the usual rule, not a rule for every kind of claim.

Operation of law: Here the law ends the contract, whatever the parties want. Common cases are:

Death: In contracts of personal skill or personal service, death of the promisor ends the contract. In other contracts, such as a contract to sell goods, the legal representatives are bound, but only to the extent of the property inherited from the deceased.
Insolvency: When a person is declared insolvent by the proper authority, the person may be released from the debts as the insolvency law provides. The contracts are discharged to that extent.
Merger: When an inferior right and a superior right meet in the same person in the same property, the inferior right merges into the superior one. The lesser contract ends. An example is when a tenant buys the property he rents.
Unauthorised material alteration: If one party materially alters a written contract without the other's consent, the other party can treat the contract as ended.

MCQs usually give a short fact situation and ask which mode of discharge applies. Look for the trigger word: three years passed, died, declared insolvent, tenant buys the property, document altered.

Key formulas to remember

General limitation period for contract claims: Period to sue = 3 years from the date the right to sue arises; This is the usual period for ordinary claims under the Limitation Act, 1963. After it ends, the remedy by suit is barred.
Death of promisor: Personal skill contract: discharged. Other contract: legal representatives bound up to the estate inherited; Always check whether the contract depends on the personal skill of the deceased.
Insolvency: Insolvency order → debtor released from debts as per insolvency law; The contract is discharged to the extent the law releases the insolvent person.
Merger: Inferior right + superior right in the same person, same property → inferior right ends; Typical example: tenant becomes owner of the rented property.
Material alteration: Material alteration without consent → the other party may avoid the contract; Applies to a written contract. A trivial or consented change does not discharge it.

How to solve Discharge by Lapse of Time and Operation of Law questions

Use this method for any MCQ on lapse of time or operation of law.

1Read the facts and underline the trigger: time passed, death, insolvency, rights meeting in one person, or document altered.
2Match the trigger to a category: lapse of time or operation of law.
3For lapse of time, check whether the limitation period has passed. If it has, the right to sue is barred.
4For death, ask if the contract needs personal skill, such as painting, singing or personal service. If yes, it is discharged. If no, legal representatives are bound up to the estate inherited.
5For insolvency, check that the person has been declared insolvent. Mere financial trouble is not enough.
6For alteration, check that it is material, made by one party and made without consent.
7Eliminate options that name a different mode of discharge, such as performance or agreement, then choose the one that fits.

Quickest way: Trigger-word matching

When to use it: Use this when a fact-based MCQ must be solved in under a minute.

Spot the keyword: years, died, insolvent, tenant buys, altered.
Years passed: barred by limitation. Died: ask if personal skill. Insolvent: released by law. Tenant buys: merger. Altered: avoidable.
Choose the option that states the legal effect, then move on.

Common mistakes in Discharge by Lapse of Time and Operation of Law

Thinking death of the promisor always ends a contract.
Students remember the personal skill case and apply it to every contract.
Fix: Split into two: personal skill ends the contract; other contracts bind the legal representatives up to the estate inherited.
Saying the legal representatives pay from their own pocket.
Students ignore the limit on liability.
Fix: Remember that liability is limited to the property received from the deceased.
Believing that a time-barred debt is destroyed completely.
The phrase discharge sounds like total extinction.
Fix: State it as: the remedy by suit is barred after the limitation period, so the claim cannot be enforced in court.
Treating any financial difficulty as insolvency.
Everyday use of the word insolvent is loose.
Fix: Look for a formal declaration by the proper authority before applying discharge by insolvency.
Confusing merger with novation.
Both replace one right with another.
Fix: Novation needs agreement of the parties and a new contract. Merger happens by law when two rights meet in one person.
Treating every change in a document as discharging the contract.
Students overlook the words material and without consent.
Fix: Only a material change made by one party without the other's consent allows the other party to avoid the contract.

Worked examples

Example 1

A famous singer, Meera, agrees to perform at a wedding on 10 March. She dies on 5 March. What is the effect on the contract? (a) Her legal representatives must perform (b) The contract is discharged by operation of law (c) The contract is discharged by lapse of time (d) The contract is discharged by novation

Show the solution

The trigger is the death of the promisor.
Singing is a matter of personal skill, so only Meera could perform.
Death in a personal skill contract discharges the contract by operation of law.
Option (a) is wrong because representatives cannot sing for her. Options (c) and (d) have no matching facts.

Answer: (b) The contract is discharged by operation of law.

Example 2

Ravi lent ₹50,000 to Sunil under a simple contract. The due date passed and Ravi did nothing for four years. Which statement is most correct? (a) Ravi can sue as of right (b) The contract is discharged by merger (c) The remedy by suit is barred by limitation (d) Sunil is declared insolvent

Show the solution

The trigger is time: four years have passed after the due date.
The general limitation period for such a claim is three years.
Four years is more than three, so the period has expired.
The right to sue in court is therefore barred. Nothing in the facts points to merger or insolvency.

Answer: (c) The remedy by suit is barred by limitation.

Exam tips

Expect fact-based MCQs that ask for the mode of discharge. Learn the trigger words.
Know the death rule in both parts: personal skill, and other contracts up to the estate inherited.
Remember the usual three-year period for contract claims, but read the question for any different figure it gives.
Keep merger, novation and alteration apart, since options often place them side by side.
If unsure, pick the option that matches the legal effect, not one that adds an unstated fact.

Practice questions from Discharge of Contracts

Discharge by Lapse of Time and Operation of Law: frequently asked questions

Does death of the promisor discharge a contract?

Only when the contract needs personal skill or personal service. In other contracts, the legal representatives must perform, but only up to the property they inherit from the deceased.

What is discharge of contract by lapse of time?

It means the limitation period for suing has expired. The right to enforce the contract in court is barred. For ordinary contract claims, the usual period is three years.

What is discharge by operation of law?

It is when the law ends the contract, not the parties. Examples are death in personal skill contracts, insolvency, merger and unauthorised material alteration.

How does merger discharge a contract?

When a lesser right and a higher right in the same property come together in one person, the lesser right ends. For example, a tenant who buys the rented property no longer holds a lease.
