Contingent Contracts: Meaning and Enforcement under Section 32

Updated 11 October 2026 · Fact-checked

A contingent contract is a contract to do or not to do something if a collateral event does or does not happen (Section 31). Under Section 32, if it depends on an uncertain future event happening, it cannot be enforced until that event has happened. If the event becomes impossible, the contract becomes void.

Understand Contingent Contracts: Meaning and Enforcement (Section 32)

Some contracts do not start working at once. They depend on something else. You promise to pay if a thing happens, or if it does not happen. That is a contingent contract.

Section 31 defines it: a contract to do or not to do something, if some event, collateral to the contract, does or does not happen. Collateral means the event is not part of the promise itself. It is a side event. Example: A contracts to pay B ₹10,000 if B's house is burnt. The burning is the collateral event. It is not the act promised.

Section 32 deals with contracts that depend on an event happening. Such a contract cannot be enforced by law unless and until that event has happened. If the event becomes impossible, the contract becomes void. Example: A agrees to buy B's horse if A survives C. Nobody can enforce this until C dies in A's lifetime. Another example: A promises to pay B a sum when B marries C. If C dies without being married to B, the contract becomes void.

The event must be uncertain and in the future. It must also be collateral. A contingent contract is not void merely because it is contingent. Only its enforcement waits for the event. But it can become void in two different ways. Under Section 32, the contract was valid when made, and it becomes void if the event later becomes impossible. Under Section 36, the event is already impossible when the agreement is made. A contingent agreement to do or not to do something if such an impossible event happens is void, whether or not the parties knew of the impossibility when they made it. Example: A agrees to pay B ₹1,000 if B marries A's daughter C, but C was already dead at the time of the agreement. The agreement is void.

For MCQs, remember this contrast. Section 30 says agreements by way of wager are void, and no suit lies to recover anything won on a wager. A contingent contract is not void just because it depends on an uncertain event. Textbooks add a general idea to tell the two apart: in a wager, the parties are really betting on the outcome of an uncertain event. In a contingent contract, the event is a collateral condition to a promise, as in the Section 31 illustration of paying ₹10,000 if B's house is burnt. This test is a general principle. It is not the wording of Section 30.

Key formulas to remember

Definition (Section 31): Contingent contract = contract to do or not to do something, if some collateral event does or does not happen; The event must be collateral, meaning it is not part of the promised act itself.
Enforcement when event must happen (Section 32): Enforceable only after the event has happened; Until then, no one can sue to enforce it.
Event becomes impossible (Section 32): Event impossible → contract void; Example: A promises to pay B when B marries C. C dies unmarried to B. The contract is void.
Event must not happen (Section 33): Enforceable when the event's happening becomes impossible, and not before; Example: pay if a ship does not return. The ship sinks. Enforce when it sinks.
Future conduct of a person (Section 34): Event is impossible when the person does something that rules out acting that way within any definite time; Example: A pays B if B marries C. C marries D. B's marriage to C is now treated as impossible.
Impossible event (Section 36): Contingent agreement on an impossible event → void; Void whether or not the parties knew it was impossible when they made it.
Wager (Section 30): Wagering agreement → void; no suit to recover winnings; A contingent contract is not void for being contingent.

How to solve Contingent Contracts: Meaning and Enforcement (Section 32) questions

Use this method for any question on contingent contracts, whether MCQ or written.

1Read the promise. Ask: does performance depend on some other event? If yes, it may be contingent.
2Check the event is collateral, uncertain and in the future. If it is the promised act itself, it is not contingent.
3Decide whether the contract depends on the event happening (Section 32) or not happening (Section 33).
4Find the current status of the event: has it happened, is it still pending, or has it become impossible?
5Apply the rule. Happened: enforceable. Pending: not yet enforceable. Impossible (for a happening-type contract): void. If a fixed time was set (Section 35), a happening-type contract also becomes void if the event has not happened when that time expires.
6If the question mentions a fixed time, a person's conduct, or an event that was already impossible when the agreement was made, check the matching section (35, 34 or 36).
7If the question describes a bet on the outcome of an uncertain event, think of a wager. Section 30 makes wagers void and bars suits to recover winnings. The idea of what makes an agreement a wager is a general principle, not Section 30's wording.
8State the conclusion in one line and name the section.

Quickest way: Three-question check for MCQs

When to use it: Use it when you have under a minute for a one-mark MCQ on contingent contracts.

Q1: Is there an 'if' event outside the promise itself? No means not contingent.
Q2: Must the event happen, or must it not happen? Happen: Section 32. Not happen: Section 33.
Q3: What is the event's status? Happened: enforceable. Pending: not enforceable yet, but if a fixed time was set and it has expired without the event happening, a happening-type contract is void (Section 35). Impossible: void for Section 32.
If the options describe a plain bet on an uncertain event, think wager: void under Section 30, and no suit to recover winnings.

Common mistakes in Contingent Contracts: Meaning and Enforcement (Section 32)

Saying a contingent contract is void just because it depends on an uncertain event.
Students mix it up with a wagering agreement, which is also tied to uncertainty.
Fix: A contingent contract is not void merely because it is contingent. Enforcement waits for the event. It becomes void only in cases such as the event becoming impossible (Section 32) or being impossible when agreed (Section 36). A wager is void under Section 30.
Thinking the contract can be enforced as soon as it is signed.
Students forget the words 'unless and until that event has happened'.
Fix: Under Section 32, enforcement starts only after the event has happened.
Treating an event that is part of the promise as the contingency.
The word 'if' appears and students assume it is contingent.
Fix: The event must be collateral. The promised act itself is not the contingency.
Mixing up Section 32 and Section 33.
Both deal with enforcement, and the wording looks similar.
Fix: Section 32: event happens. Section 33: event does not happen, enforceable when its happening becomes impossible.
Saying the contract stays alive when the event becomes impossible.
Students think waiting longer could still help.
Fix: Under Section 32, if the event becomes impossible, the contract becomes void.
Treating every contract that pays on an uncertain event as a wager.
Both depend on an uncertain event, so they look alike.
Fix: Section 30 voids wagers only. The Section 31 illustration of paying ₹10,000 if B's house is burnt is a contingent contract. Ask whether the event is a collateral condition to a promise or the subject of a bet. That test is a general principle, not Section 30's wording.

Worked examples

Example 1

Ramesh agrees to pay Sunita ₹50,000 if Sunita's shop is destroyed by fire. Is this a contingent contract? When can Sunita enforce it?

Show the solution

The promise is to pay ₹50,000. The promise depends on the shop being destroyed by fire.
The fire is an uncertain future event. It is collateral, since it is not the act of paying.
So this is a contingent contract under Section 31, much like the house-burning illustration.
The contract depends on an event happening, so Section 32 applies.
Sunita cannot enforce it until the fire has happened.

Answer: Yes, it is a contingent contract. Sunita can enforce it only after the shop has been destroyed by fire. If the event became impossible, the contract would be void.

Example 2

Which of the following is correct? Meera agrees to pay Karan ₹20,000 when Karan marries Divya. Divya dies without marrying Karan. (A) The contract is enforceable after a year (B) The contract becomes void (C) The contract is voidable at Karan's option (D) The contract is valid and Meera must pay half

Show the solution

The payment depends on an event happening: Karan's marriage to Divya.
This is a contingent contract under Section 32.
Divya has died unmarried to Karan. The event has become impossible.
Under Section 32, when the event becomes impossible, such contracts become void.
Options A, C and D give results the section does not provide.

Answer: Option (B). The contract becomes void under Section 32.

Exam tips

In Paper 4, the common one-mark questions ask: when is a contingent contract enforceable, and what happens if the event becomes impossible. Learn those two lines word for word.
Always read the 'if' carefully. 'If it happens' points to Section 32. 'If it does not happen' points to Section 33.
Watch for options that call a contingent contract 'void' or 'voidable' by default. Both are wrong.
For a written answer, give the definition, name the section, add one illustration, and state the result. That structure collects the marks.
There is no negative marking in Paper 4, so never leave an MCQ blank.

Contingent Contracts: Meaning and Enforcement (Section 32): frequently asked questions

What is a contingent contract under the Indian Contract Act?

It is a contract to do or not to do something if some collateral event does or does not happen. This is the definition in Section 31. An example is paying ₹10,000 if the other person's house is burnt.

What does Section 32 say?

It says contracts contingent on an uncertain future event happening cannot be enforced by law unless and until that event has happened. If the event becomes impossible, such contracts become void.

What is the difference between a contingent contract and a wagering agreement?

A contingent contract is not void just because it depends on an uncertain event. Under Section 31 the event is collateral, and under Section 32 enforcement waits for it. A wagering agreement is void under Section 30, and no suit can recover anything won on it. Textbooks add the general idea that in a wager the parties are really betting on the outcome, but that is not Section 30's wording.

What are the essentials of a contingent contract?

There must be a contract to do or not to do something. Performance must depend on an event that is collateral to the contract. The event must be uncertain and in the future.
