Quasi Contract for CLAT: 5 Situations Explained

📑 On this page

⚡ The short answer

A quasi-contract is an obligation the law imposes where there is no agreement at all, so that nobody is unjustly enriched at another's expense. It covers five situations: necessaries supplied to someone who can't contract, paying dues another is legally bound to pay, benefits not meant as gifts, finding lost goods, and money paid by mistake or under pressure.

🎬 The 30-second story

The tax that wasn't Rohan's

“Auction notice for unpaid tax? On the flat I rent?”

📜

Rohan

Owner Zoya is abroad. An auction would end Rohan's lease.

“Here's ₹60,000. Please cancel the auction.”

🏛️

Rohan

Rohan clears Zoya's arrears himself.

“I never asked you to pay. No deal, no refund.”

✈️

Zoya

Zoya returns and refuses to repay.

“So you keep the house and my money?”

⚖️

Rohan

They never agreed anything about this.

Tara's ruling: Rohan recovers the ₹60,000. Zoya was legally bound to pay the tax, and Rohan paid because his own lease was at stake. No contract is needed: Zoya can't keep a debt cleared with Rohan's money.

What is a quasi-contract?

‘Quasi’ means ‘as if’. There is no offer, no acceptance and no meeting of minds. The law simply treats the parties as if they had a contract, because one of them holds a benefit that, in fairness, belongs to the other.

The engine is unjust enrichment: the defendant got a benefit, at the claimant's expense, and keeping it would be unjust. Hit all three and the law creates a duty to repay. Miss one, say the benefit was a gift, and nothing is owed.

🤝Contract

Born from the parties' choice

•Needs offer, acceptance, consideration
•Parties set the terms
•Breach earns damages

⚖️Quasi-contract

Imposed by law, whatever anyone wanted

•No agreement, often no contact
•The law sets the duty
•Only the benefit goes back

Test	Contract	Quasi-contract

What you claim	Performance or damages	Value of the benefit, or the thing itself

A valid contract? Sue on it. Quasi-contract fills the gap where there isn't one.

📌 What CLAT actually expects

The passage will state one of these rules, often in the statute's words. Check each ingredient against the facts: lawful? a gift? accepted? legally bound? One missing ingredient flips the answer.

What are the five quasi-contract situations?

🧩 At a glance

Five ways to owe without agreeing

🍲Necessaries to the incapable

For a minor or person of unsound mind: paid from their property.

🧾Paying another's legal dues

You pay what another is bound by law to pay, to protect your own interest.

🛠️Benefit not meant as a gift

Lawfully done or delivered, and they chose to enjoy it: pay or return.

👛Finder of goods

Pick up lost property and you carry a bailee's duties.

🔁Mistake or coercion

Money or goods given by mistake or under pressure go back.

Necessaries for someone who can't contract

A minor's agreement is void, so a grocer who feeds a sixteen-year-old on credit has no contract to sue on. The law plugs the hole: whoever supplies necessaries suited to the incapable person's condition in life, to them or their legal dependants, is reimbursed from that person's property.

✓Property, not person: the minor is never personally liable. No property, no recovery.
✓Condition in life: food, clothes, schooling, medical care and legal help usually qualify; luxuries don't.
✓Actual need: a fifth jacket for a minor who owns four isn't a necessary, even if the seller didn't know.
✓Fair value only, not whatever price was agreed.

Paying dues someone else is bound to pay

🔗 Who owes whom

Rohan's rescue, mapped

Zoya → Municipality: owes property tax
Rohan → Municipality: pays to stop auction
Rohan → Zoya: claims reimbursement — Zoya's debt is cleared with Rohan's money.

Three ingredients. The payer must be interested: his own right or property is at risk if the money stays unpaid. The other must be bound by law to pay, not just morally. And the payment must actually be made. A friend who pays out of kindness has nothing at stake, so this rule doesn't help him.

Can you charge for a favour nobody asked for?

Only sometimes. If you lawfully do or deliver something for another, not meaning it as a gift, and they enjoy the benefit, they must pay or return it. The catch is ‘enjoy’: they must have been able to refuse and chosen to keep it.

🧭 Decision flow

Can you claim for a benefit you gave?

❓ Does a valid contract already cover this work or delivery?

Yes →

Sue on the contract, not in quasi-contract

No ↓

❓ Was the act or delivery lawful, with no fraud or dishonesty?

No →

No claim: the act wasn't lawful

Yes ↓

❓ Did you mean it as a gift or free favour?

Yes →

No claim: a gift stays a gift

No ↓

❓ Could they refuse it, and did they accept and enjoy it anyway?

Yes →

Pay reasonable value or return the thing

No →

No claim: you forced a benefit on them

The law ignores officious interference.

Kabir's delivery boy drops forty lunch boxes at Zoya's office by mistake, and her team eats them. Lawful, not a gift, enjoyed when they could have sent it back: Zoya's office pays a fair price. But if Aarav repaints Zoya's gate while she's away, unasked, she never had a chance to say no. His bill fails.

⚠️ The heroic-rescue trap

Rohan saves Kabir's stock from a fire, then sends an invoice. If he acted as a good neighbour, he acted gratuitously and gets nothing. Read the facts for intention, not the size of the benefit.

What must a finder of lost goods do?

Walking past a lost wallet costs you nothing. Picking it up changes your position: once found goods are in your custody, the law treats you like a bailee, someone holding another's property, though the owner never handed it over.

🕒 Timeline

Zoya finds a phone on the metro

1
Step 1

Takes it into custody

The bailee's duties start now.
2
Step 2

Takes reasonable care

Looks after it as she would her own, and doesn't use it.
3
Step 3

Tries to trace the owner

A notice, a call to a saved contact, the lost-and-found desk.
4
Step 4

Owner turns up

She returns it. She can't sue for her costs but can hold the phone until paid, and can sue for any reward offered.
5
Step 5

Last resort: sale

If the owner can't be found or won't pay, she may sell if it's perishing or her charges reach two-thirds of its value.

Must you return money paid by mistake or under pressure?

Yes. Whoever receives money or goods by mistake or under coercion must return them. Coercion here means any unlawful pressure, like a transporter refusing to release your goods until you pay a charge he isn't owed.

Situation	Must it go back?	Why
Bank credits ₹50,000 to the wrong account	Yes	Mistake of fact; spending it is no defence
Tax paid under a law later struck down	Yes	Mistake of law counts too
Illegal fee paid to get your goods released	Yes, the illegal part	Paid under pressure
Taxpayer already recovered the tax from customers	No	He has suffered no loss to restore

💡 ‘Ignorance of law is no excuse’ doesn't apply here

That maxim stops you escaping liability. It doesn't let someone keep money paid because both sides misread the law. Money paid under a mistake of law is recoverable.

Where does a quasi-contract claim stop?

✓No damages or specific performance: no contract was broken; you get the benefit's value or the thing.
✓Contract first: if a valid contract covers it, its terms decide.
✓Account for what you got: show your own gains before claiming a refund.
✓No busybodies: forced services earn nothing.
✓The State isn't exempt: it pays for work it accepts under a defective contract.

Which cases shaped quasi-contracts?

🏗️

Landmark case · 1961 · Supreme Court

State of West Bengal v B.K. Mondal & Sons

📋

What happened

Civil Supplies officers asked a building firm to put up a kutcha road, guard room, kitchen and other structures. The firm built them and the department used them. No contract was signed in the form the law required for government contracts, so the State refused to pay.

❓

The question

With no valid contract, could the firm recover anything?

🔨

What the court held

The firm acted lawfully and didn't intend a gift. The State could have refused the work or had it removed; having accepted and used it, it had to compensate. The claim rested on accepting the benefit, not on a contract.

What CLAT takes from it: Lawful act + not a gift + voluntary enjoyment = pay, even for the government.

🧾

Landmark case · 1958 · Supreme Court

Sales Tax Officer, Banaras v Kanhaiya Lal Mukundlal Saraf

📋

What happened

A firm paid sales tax on forward transactions. The High Court later held that tax invalid. Refusing a refund, the authorities said the firm paid voluntarily, under a mistake of law, and the money was spent.

❓

The question

Is money paid under a mistake of law recoverable?

🔨

What the court held

‘Mistake’ covers mistakes of law as well as fact, so the tax had to be refunded. That the State had spent it made no difference.

What CLAT takes from it: Mistake of law is enough, and ‘we've spent it’ is no defence.

🌳

Landmark case · 1968 · Supreme Court

Mulamchand v State of Madhya Pradesh

📋

What happened

Mulamchand deposited ₹10,000 with the State for the right to collect lac from forest land, but the contract wasn't executed in the form the Constitution requires. He collected some lac, then sued for his deposit.

❓

The question

With the contract void, did he automatically get his money back?

🔨

What the court held

The contract was void and restitution was possible in principle. But a claimant must account for what he received. With no reliable evidence of the lac collected or his profit, Mulamchand's claim failed.

What CLAT takes from it: Show what you gained before claiming what you gave.

How could CLAT ask it?

ℹ️ No past CLAT question yet

No CLAT UG paper from 2018 to 2025 asked about quasi-contracts. These two are our own CLAT-style practice.

🧪 CLAT-style practice (not a past question) Non-gratuitous act

Where a person lawfully does anything for another person, or delivers anything to him, not intending to do so gratuitously, and such other person enjoys the benefit thereof, the latter is bound to compensate the former or restore the thing. Liability arises only where the receiver, free to refuse, voluntarily accepts and enjoys it.

Kabir's bakery wrongly delivers a ₹4,000 cake, ordered by her neighbour, to Zoya. Assuming friends sent it, she serves it at her party. Kabir demands payment. Which is correct?

AZoya need not pay, as there is no contract.

BZoya need not pay, as the wrong delivery was Kabir's mistake.

CZoya must pay reasonable compensation, as she accepted and enjoyed a delivery not meant as a gift.

DZoya must pay the price plus damages for breach.

Reveal answer + reasoning

Answer: C

Lawful delivery; a business doesn't deliver cakes as gifts; Zoya could have returned it but served it. Liability arises without any contract.

Why the others fail

A — the rule applies precisely where there's no contract.
B — the sender's mistake doesn't let the receiver keep the benefit free.
D — no contract, so no breach and no damages.

🧪 CLAT-style practice (not a past question) Payment by an interested person

A person who is interested in the payment of money which another is bound by law to pay, and who therefore pays it, is entitled to be reimbursed by the other. A person is ‘interested’ only if non-payment would harm some right or property of his own.

Aarav owes the municipality ₹30,000 in water tax on his house. His friend Rohan, who has no interest in the house, pays it out of sympathy. After a quarrel, Rohan demands repayment. Which is correct?

ARohan can recover, as Aarav was bound by law to pay.

BRohan cannot recover under this principle, as he was not interested in the payment.

CRohan can recover, as Aarav was enriched at his expense.

DRohan cannot recover, as he paid voluntarily.

Reveal answer + reasoning

Answer: B

Both limbs are needed. Aarav was bound by law, but Rohan had nothing of his own at risk, so his payment was a kindness.

Why the others fail

A — meets only one of two conditions.
C — imports a fairness idea the passage doesn't adopt.
D — right result, wrong reason: an interested payer also pays voluntarily.

Frequently asked questions

Is a quasi-contract a real contract?

No. There is no offer, acceptance, consideration or consent. The law imposes an obligation that looks contractual so that nobody keeps a benefit that in fairness belongs to someone else. Hence ‘quasi’, meaning ‘as if’.

What is unjust enrichment in simple words?

Getting richer at someone else's expense in a way the law finds unfair. You received a benefit, it came at another's cost, and keeping it would be unjust. When all three exist, you must repay or return it.

Can a minor be made to pay for necessaries?

Not personally. The supplier of necessaries suited to the minor's condition in life is reimbursed only from the minor's property; no property, no recovery. Luxuries, or things the minor already had enough of, don't count.

Can I keep money credited to my account by mistake?

No. Money or goods received by mistake must be returned, whoever caused the mistake, and having spent the money is no defence. Dishonestly keeping it can also be a crime.

Can a finder of lost goods claim a reward?

Only if the owner offered a specific reward; then the finder can sue for it and hold the goods until paid. Otherwise there's no suit for expenses, but the finder can keep the goods until reasonable costs of care and tracing the owner are paid.
