Contingent Contract for CLAT: Rules, Flowchart, PYQs

📑 On this page

⚡ The short answer

A contingent contract is a valid contract to do or not do something if an uncertain future event, outside the deal itself, does or does not happen. Nobody can enforce it until the event is settled. If the event becomes impossible, the contract becomes void; if it was impossible from the start, the agreement was void all along.

🎬 The 30-second story

The Metro clause

“If the new Metro station opens by 31 March, I'll rent your shop at ₹60,000 a month.”

🚇

Kabir

Zoya signs.

“It's January. Pay the first month now!”

📅

Zoya

The station is still a building site.

“Read the clause. No station, no rent. Yet.”

🚧

Kabir

Zoya sues anyway.

“Station opened on 20 March. Pay up.”

🎉

Zoya

Eleven days inside the deadline.

Tara's ruling: In January Zoya's suit fails: the contract is real, but its trigger hasn't happened. Once the station opens in time, Kabir must pay. Had 31 March passed with no station, the contract would have become void.

What is a contingent contract?

Most contracts are absolute: the duty is fixed from the start, even if the date is later. A contingent contract puts a gate in front of the duty. It only bites if a named, uncertain event happens (or doesn't). Insurance is the classic example: the insurer's promise sleeps until your shop actually burns. The contract exists from day one; only enforcement waits.

A contingent contract is a contract to do or not to do something if some event, collateral to it, does or does not happen. It cannot be enforced until that event happens.

Contingent contract

When is an event 'uncertain' and 'collateral'?

Two words carry the definition. Uncertain: the event may never happen. Collateral: it sits beside the bargain, so neither party has promised to bring it about. If the 'event' is really one side's performance, it's an ordinary contract.

The clause	Contingent?	Why
Kabir will buy Zoya's flat if the bank sanctions his loan	Yes	The bank's decision is uncertain and outside the deal
Kabir will pay ₹5,000 if Zoya paints his café	No	Painting is Zoya's side of the bargain: consideration, not a collateral event
Kabir will pay on 1 June	No	A date is certain to come. Futurity isn't contingency
Kabir will pay when he is in a position to	Usually no	Courts read it as an absolute debt, payable within a reasonable time
Kabir will pay if he feels like it	No contract	A promise resting on the promisor's whim binds nobody

⚠️ ‘If’ is not ‘when’

'Pay when the goods arrive' usually fixes the time of an absolute duty; 'pay if they arrive' makes the duty itself depend on arrival. Test: if the event never happens, is the promisor off the hook? Only a yes makes it contingent.

When can a contingent contract be enforced?

Every clause is either if X happens or if X does not happen, with or without a deadline. Run any fact pattern through this tree.

🧭 Decision flow

Can the promisee sue yet?

❓ Was the event impossible when the agreement was made?

Yes →

Void from the start

No ↓

❓ Is the promise tied to the event happening or not happening?

Happening →

❓ Has the event happened (within any fixed time)?

Yes →

Enforceable now

No ↓

❓ Has it become impossible, or has the fixed time run out?

Yes →

The contract becomes void

Benefits already received go back.

No →

Not yet: the promisee must wait

Not happening →

❓ Has the event become impossible, or has the fixed time expired without it?

⚔️ Side by side

‘If it happens’ vs ‘if it doesn't happen’

✅If X happens

Wait for the event

•Enforceable once X actually happens
•Dies if X becomes impossible
•With a deadline, dies when it passes without X

🚫If X doesn't happen

Wait until X can no longer happen

•Enforceable once X becomes impossible
•Not enforceable just because X hasn't happened yet
•With a deadline, enforceable when it passes, or earlier once it's certain X won't happen

Test	If X happens	If X doesn't happen
Example	Pay if the ship arrives by 30 June	Pay if the ship does not arrive by 30 June
Ship sinks on 10 April	Void at once	Enforceable at once

The same sinking ship kills one contract and triggers the other.

🕒 Timeline

Kabir's spice shipment: a ‘within a fixed time’ clause

1
1 Jan

Contract signed

Rohan will buy Kabir's saffron if the shipment lands by 30 June.
2
March

Ship still at sea

Nothing is enforceable yet.
3
Path A

Docks on 18 May

Event happened in time: Rohan must buy.
4
Path B

Sinks on 10 April

Now impossible: void at once, no waiting for June.
5
Path C

1 July, still delayed

Deadline passed: void, even if it docks on 3 July.

What happens if the event becomes impossible?

Timing decides the label. If the event was already impossible when they agreed, the agreement is void from the start, even if nobody knew. Kabir promising Rohan ₹1 lakh if Rohan marries Kabir's daughter, who unknown to both had died the week before, is void.

If the event was possible then but later becomes impossible, the contract becomes void. Kabir promises Rohan a gift if Rohan marries Ishita; Ishita dies unmarried. Anything already handed over must be restored.

When does a person's future conduct become ‘impossible’?

If the event is how a living person will act at some unspecified time, it counts as impossible once that person makes it impossible within any definite time, or except through further contingencies. Aarav promises Zoya a flat if she marries Rohan; Rohan marries someone else. A divorce could reopen the chance, but the law won't wait. The contract is void.

📌 What CLAT actually expects

The passage will state the rule. Find the event, check whether it's 'happens' or 'doesn't happen', check any deadline, then ask: is the event done, still open, or dead?

How is a contingent contract different from a wager?

A bet on the IPL final also hangs on an uncertain event. But a contingent contract is enforceable once its event happens; a wager is void however it turns out.

⚔️ Side by side

Contingent contract vs wager

⏳Contingent contract

A real deal with a trigger

•Genuine interest beyond the event
•Often one-way: one side pays if X happens
•Enforceable once the event happens

🎲Wager

Pure win-or-lose on chance

•Only interest is the stake
•Each side may win or lose on the result
•Void, whoever wins

Test	Contingent contract	Wager
Example	Fire insurance on your own shop	₹2,000 on who wins the final
Link	Every wager rests on an uncertain event	Most contingent contracts aren't wagers

Uncertainty is common to both; interest and enforceability separate them.

🧩 At a glance

Contingent contracts you meet every day

🔥Insurance

Pays only if the insured risk happens.

🛡️Indemnity

Makes good a loss, if a loss occurs.

🏦Guarantee

The surety pays only if the borrower defaults.

📝Subject to approval

A land sale waits on government permission.

💳Subject to finance

The purchase proceeds only if the loan is sanctioned.

💡 Contingency vs frustration in one line

A contingent contract ends by its own terms: the parties foresaw the event. Frustration ends a contract through an event nobody provided for.

Which cases show contingency at work?

🔥

Landmark case · 1957 · Supreme Court

Commissioner of Excess Profits Tax v Ruby General Insurance Co

📋

What happened

An insurer argued, in a tax dispute, that reserves kept for unexpired policies weren't real debts, since nothing was payable until a loss occurred.

❓

The question

What kind of contract is insurance?

🔨

What the court held

That insurance is a contingent contract 'does not admit of argument'. Until the risk happens, nothing is enforceable.

What CLAT takes from it: Insurance is the textbook contingent contract.

🏠

Landmark case · 1989 · Supreme Court

Ramzan v Hussaini

📋

What happened

A brother agreed to sell his mortgaged house to his sister once she paid off the mortgage. She did so in 1970 but sued only in 1984.

❓

The question

When did her right to enforce begin?

🔨

What the court held

A typical contingent contract, enforceable the moment the mortgage was redeemed. The three-year limit ran from then, so her suit was late.

What CLAT takes from it: When the event happens, the contract wakes up, and so does the clock.

🏭

Landmark case · 2015 · Supreme Court

Nandkishore Lalbhai Mehta v New Era Fabrics

📋

What happened

A mill owner agreed to sell land subject to permissions and its workers' union agreeing. The buyer paid ₹11.5 lakh; the union refused.

❓

The question

Could the buyer force the sale by waiving the union's consent?

🔨

What the court held

No. The sale was a contingent agreement; once the union refused, it had ceased. The buyer got his money back with the agreed 18% interest.

What CLAT takes from it: When the condition fails, the deal goes with it.

How has CLAT asked it?

CLAT 2019 ran three back-to-back questions on conditions. The examples come from property law, but the logic is the same: find the event, check whether it's possible, and check whether it happened as required.

📝 Asked in CLAT 2019 · Q86 Impossible condition

Principle: An interest created, dependent upon a condition fails, if the fulfillment of the condition is impossible. Facts: A promises to pay Rs. Ten Lakh to B on condition that he shall marry A's daughter C. At the date on which A gave Rs. Ten Lac to B, C was dead.

Choose the correct answer.

AB's interest fails

BB's interest fails because of immorality

CB's interest fails because of prohibition by law

DB's interest does not fail

Reveal answer + reasoning

Answer: A

Our solution, as no official key exists for this 2019 set. A dead person can't be married, so the condition is impossible and B's interest fails, whether C died before or after the promise.

Why the others fail

B — nothing here is immoral.
C — no law forbids the marriage; it just can't happen.
D — contradicts the principle.

📝 Asked in CLAT 2019 · Q87 Condition met too late

Principle: A condition must be complied with after the happening of the event to which such a condition is attached. Facts: A promises to pay Rs. 5,000 to B on the condition that he shall marry with the consent of C, D and E. B marries without the consent of C, D and E, but obtains their consent after the marriage.

Choose the correct answer.

AB has fulfilled the condition

BB has not fulfilled the condition

CThe condition is illegal

DB must divorce his wife

Reveal answer + reasoning

Answer: B

Our solution. The wording is clumsy, but the condition attaches to the marriage: B must marry with their consent. Consent obtained afterwards can't change how the marriage happened.

Why the others fail

A — treats late consent as prior consent.
C — nothing makes the condition illegal.
D — the principle says nothing of the sort.

📝 Asked in CLAT 2019 · Q88 Event not happening in fixed time

Principle: A condition must be complied in order to claim the benefit of an agreement. Facts: A agrees to transfer a farm to B, if B shall not go to England within three years after the date of the agreement, his interest in the farm shall cease. B does not go to England within the term prescribed.

Choose the correct answer.

AB's interest in the farm continues

BB's interest in the farm does not continue

CB has a fundamental right to go to England or not to go to England and hence the condition is illegal

DThe agreement between A and B is void

Reveal answer + reasoning

Answer: B

Our solution. Read slowly: if B does not go to England within three years, his interest ends. Rewrite it as 'B keeps the farm only if he goes'. He didn't, so the interest does not continue.

Why the others fail

A — misreads 'shall not go' as a ban B obeyed; it's the trigger.
C — fundamental rights bind the State, not private deals.
D — the agreement was valid; only B's interest ends.

🎯 In a nutshell

A contingent contract is valid now, enforceable only when an uncertain, collateral event is settled.
If X happens: enforce once it does; void if it becomes impossible or the deadline passes.
If X doesn't happen: enforce once X is impossible, the deadline passes, or it's certain X won't happen.
An event impossible from the start makes the agreement void, known or not.
A certain date isn't a contingency, and a wager is void.

Frequently asked questions

What is a contingent contract in simple words?

A contract that says 'I'll do this if that happens', where 'that' is an uncertain future event outside the deal, like a loan being sanctioned or a fire. It exists from the moment it's made, but can be enforced only once the event happens or, for a 'does not happen' clause, once it can no longer happen.

Is a contingent contract valid or void?

Valid. Uncertainty only postpones enforcement. It becomes void later if the event becomes impossible or a fixed deadline passes without it. It is void from the start only if the event was already impossible when the parties agreed, whether or not they knew.

Is insurance a contingent contract?

Yes, it's the standard example. The insurer pays only if an uncertain event, such as fire, theft or an accident, happens during the policy. Indemnity and guarantee work the same way: the promise to pay wakes up only if a loss or a default occurs.

How is a contingent contract different from a wagering agreement?

Both depend on an uncertain event. But in a wager each side's only interest is the stake and each may win or lose, so the law makes it void. A contingent contract involves a genuine interest, often runs one way, and is enforceable once the event happens.

Is a promise to pay 'when I get my salary' contingent?

Usually not. 'When' or 'as soon as I am able' generally fixes the time of an absolute duty. Courts have read 'when in a position to pay' as a debt payable within a reasonable time. Ask whether the promisor walks free if the event never happens; if not, it isn't contingent.
