Contingent Contracts: Meaning and Drafting Explained

Updated 11 October 2026 · Fact-checked

A **contingent contract** is a contract to do or not to do something if an event collateral to the contract does or does not happen (Section 31). To solve a question, identify the event, check whether it is uncertain and collateral, then apply Sections 32 to 36. In drafting, state the event as a clear condition.

Understand Contingent Contracts: Meaning and Drafting

A contingent contract is a contract to do or not to do something, if some event, collateral to the contract, does or does not happen. The Act's own illustration: A contracts to pay B ₹10,000 if B's house is burnt. The promise to pay exists now, but the duty to pay depends on the fire.

Three features matter. First, there is a valid contract. Second, the performance depends on a future event. Third, the event is collateral: it is not part of the promise itself and neither party is bound to bring it about. A contract of insurance, indemnity and guarantee are common examples in practice.

The event must be uncertain. If it is bound to happen, the contract is not contingent. This is also why a contingent contract differs from a wager under Section 30. A wager is void, and nothing can be recovered on it. In a wager, each party's gain or loss depends only on the uncertain event, and neither has any other interest in it. In a contingent contract, the event is collateral to a real transaction, such as a house you own or a ship you have cargo on.

In drafting, you turn this into clauses. A condition precedent must happen before an obligation arises or before the contract binds. A condition subsequent is an event that, if it happens or does not happen, ends or changes an obligation that has already arisen. Clear drafting names the event, who bears the risk, the time limit, and what happens if the event fails.

The Act also fixes the consequences. A contract contingent on an event happening cannot be enforced until the event happens, and becomes void if the event becomes impossible (Section 32). A contract contingent on an event not happening is enforceable when the event becomes impossible (Section 33). Fixed-time contracts follow Section 35.

Key rules to remember

Definition (Section 31): Contingent contract = contract to do / not do something + if an event collateral to it does / does not happen; Example in the Act: pay ₹10,000 if B's house is burnt.
Event must happen (Section 32): Enforceable only when the event has happened; void if the event becomes impossible; Example: pay when B marries C; C dies unmarried, contract void.
Event must not happen (Section 33): Enforceable when the event becomes impossible, and not before; Example: pay if the ship does not return; enforceable when the ship sinks.
Future conduct of a person (Section 34): Event is impossible when the person does something that makes it impossible within any definite time, or otherwise than under further contingencies; Example: C marries D, so B's marriage to C is treated as impossible.
Fixed time (Section 35): Event to happen within time: void if not happened by expiry or if it becomes impossible earlier. Event not to happen within time: enforceable when time expires without it, or when it becomes certain it will not happen; Ship returns within a year: void if burnt within the year.
Impossible event (Section 36): Contingent agreement to act if an impossible event happens is void, whether or not the parties knew of the impossibility; Example: pay ₹1,000 if two straight lines enclose a space.
Wager (Section 30): Wagering agreement is void; no suit to recover what is won; Distinguish from contingent contracts by the collateral event and real interest.

How to solve Contingent Contracts: Meaning and Drafting questions

Use this order for any problem or drafting question on contingent contracts. Write each step as provision, analysis, conclusion.

1Identify the promise and the event on which it depends.
2Test whether it is a contingent contract under Section 31: is the event collateral and uncertain? If both parties only stand to win or lose on the event, consider a wager under Section 30.
3Classify the event: must it happen, or must it not happen? Is there a fixed time?
4Apply the matching section: 32 (happening), 33 (not happening), 34 (conduct of a person), 35 (fixed time) or 36 (impossible event).
5Check what has actually occurred: has the event happened, become impossible, or has time expired?
6State the conclusion: enforceable now, not yet enforceable, or void.
7If asked to draft, write the condition precedent or subsequent, the long-stop date and the consequence of failure.

Quickest way: Event-and-Time Grid

When to use it: Use for short case questions where you must decide quickly whether a promise can be enforced.

Write the event in one line and mark it H (must happen) or N (must not happen).
Note any time limit.
H: enforce only after the event; void if it becomes impossible or time runs out.
N: enforce once the event becomes impossible or certain not to occur, or the time expires without it.
Write the section number beside your conclusion.

Common mistakes in Contingent Contracts: Meaning and Drafting

Calling every conditional promise a contingent contract.
Students ignore the word collateral in Section 31.
Fix: Check that the event is outside the promise itself and uncertain.
Treating a contingent contract as a wager.
Both depend on an uncertain event.
Fix: Show the collateral event and real interest in a genuine transaction. A wager is void under Section 30, while a contingent contract is valid.
Enforcing a contract before its event has happened.
Students focus on the contract being formed.
Fix: Under Section 32, enforcement waits until the event happens. Under Section 33, until it becomes impossible.
Mixing up Sections 32 and 33.
The wording is similar.
Fix: Ask first whether the event must happen or must not happen.
Ignoring the fixed time in Section 35.
Students stop at the event.
Fix: Check the deadline. An event not occurring by expiry voids a contract that needed it to occur.
Drafting a condition without a long-stop date or failure consequence.
The clause names the event but not what follows.
Fix: Add a date, who can waive, and what happens if the condition fails.

Worked examples

Example 1

Rohan promises to pay Meera ₹2,00,000 if her warehouse in Pune is destroyed by fire. The warehouse is destroyed. Meera sues. Is Rohan liable? Is this a wager?

Show the solution

Provision: Section 31 defines a contingent contract as one to do something if a collateral event happens. Section 32 says it cannot be enforced until the event happens.
Analysis: The promise to pay depends on the fire, which is uncertain and collateral to the contract. Meera has a real interest in the warehouse, so this is not a bare wager.
The event has happened, so the bar in Section 32 has ended.
Conclusion: The contract is contingent and valid, and Rohan is liable to pay ₹2,00,000, assuming the other elements of a valid contract are present.

Answer: Yes. It is a contingent contract, not a wager, and it is enforceable now because the fire has occurred.

Example 2

Asha promises to pay Vikram ₹50,000 if the cargo ship MV Sagar does not return to Mumbai within one year. Within six months the ship is burnt and lost. Vikram demands payment. Advise.

Show the solution

Provision: Section 35 says that a contract contingent on an event not happening within a fixed time may be enforced when the time has expired without the event, or before expiry if it becomes certain the event will not happen.
Analysis: The event is the ship returning within a year. It is certain that it will not return, because the ship is burnt within the year.
The Act's own illustration (b) to Section 35 says the contract may be enforced if the ship does not return within the year, or is burnt within the year.
Conclusion: Vikram need not wait for the year to end.

Answer: Vikram can enforce the contract now, and Asha must pay ₹50,000.

Exam tips

Quote the section number with the rule, then apply it to the facts. Do not stop at the definition.
Use the Act's illustrations, such as the ship and the house, but adapt the facts to the question.
In drafting questions, include the condition, a long-stop date, waiver and the consequence of failure.
Always address wager versus contingent contract if the facts look like betting.

What is a condition precedent in a contract?

It is an event or act that must happen before an obligation arises or the contract takes effect. A drafter should state the event, the deadline, who can waive it and what happens if it fails.

When does a contingent contract become void?

If it depends on an event happening and the event becomes impossible, it is void under Section 32. Under Section 35, a contract needing an event within a fixed time is void if the time expires without it.
