Contract Law
Quasi-Contracts
Learn quasi-contractual obligations under Sections 68 to 72, including necessaries, interested payments, non-gratuitous benefits, finders and mistaken payments.
The short answer
Quasi-contract is a study label for statutory obligations imposed without agreement to reverse or compensate specified unjustified benefits under Sections 68 to 72.
What is a quasi-contract?
Chapter V calls these relations resembling those created by contract. The obligation comes from law, not from offer, acceptance or mutual consent.
The expression quasi-contract is convenient but can mislead. Sections 68 to 72 do not pretend that the parties agreed. They impose carefully defined duties where one person has received necessaries, money, goods, services or another benefit in circumstances that require reimbursement, compensation or return.
Unjust enrichment explains the common purpose, but the statutory text controls the result. A claimant should identify the exact section, prove each condition and consider any special statutory refund or remedial scheme before invoking broad fairness.
Section 68: necessaries supplied to an incapable person
A supplier of necessaries suited to the incapable person's condition in life may be reimbursed from that person's property.
The provision covers a person incapable of contracting and anyone whom that person is legally bound to support. Necessaries are not limited to bare survival. Their character depends on actual need, social condition and whether an adequate supply already existed.
The remedy is against the incapable person's property, not a personal contractual judgment based on a promise that the person lacked capacity to make. The supplier must prove both necessity and suitability, not merely that the goods were useful or expensive.
Section 69: payment by an interested person
Reimbursement may arise when a person interested in paying money pays an amount which another person was legally bound to pay.
Another person was legally bound
The primary obligation must belong to the defendant. A moral expectation or voluntary contribution is insufficient.
The claimant had a real interest
The payment must protect a legal or proprietary interest, such as preventing sale or forfeiture of the claimant's affected property interest.
The claimant was not primarily liable
A person merely paying that person's own debt cannot shift it to someone else through Section 69.
Payment, not officious interference
The claimant must actually discharge the obligation in circumstances connecting the payment with protection of the recognised interest.
Section 70: lawful non-gratuitous acts
Section 70 requires a lawful act or delivery, no intention to act gratuitously, and enjoyment of the benefit by the other person.
All three elements are cumulative. The provision does not compel payment for an unsolicited benefit that the recipient rejects or has no realistic opportunity to avoid. Enjoyment is a factual inquiry into acceptance, use or retention of the benefit.
The remedy is compensation for the thing done or restoration of the thing delivered. It does not enforce a defective bargain or automatically award the price or profit stated in that bargain.
Section 71: responsibility of a finder of goods
A person who finds goods belonging to another and takes them into custody is subject to the same responsibility as a bailee.
The finder must take reasonable care, avoid unauthorised use, make reasonable efforts to identify the owner and return the goods when the owner is found. The finder does not become owner merely by taking possession.
Related provisions give limited rights, including retention against the owner for lawful charges in specified circumstances and sale in the situations described by Section 169. A complete answer should connect the finder's Section 71 duties with those rights rather than treating custody as ownership.
Section 72: money paid by mistake or under coercion
A person receiving money or a thing delivered by mistake or under coercion must repay or return it, subject to the wider legal context.
The Supreme Court in Kanhaiya Lal treated mistake in Section 72 as extending to mistake of law as well as fact. Later restitution and tax decisions require attention to limitation, statutory refund mechanisms, passing on and unjust enrichment before ordering repayment.
The claimant must prove the payment or delivery, the operative mistake or coercion and the defendant's receipt. The defendant may raise change of position, statutory finality or another legally recognised answer where available under the governing law.
How to choose the correct section
Classify the benefit before discussing unjust enrichment in general terms.
Necessaries for an incapable person
Use Section 68 and seek reimbursement from property, not personal contractual liability.
Discharge of another's legal payment
Use Section 69 where the claimant paid to protect a recognised interest and was not primarily liable.
Accepted work, service or delivery
Use Section 70 where the act was lawful, non-gratuitous and the recipient enjoyed its benefit.
Found goods taken into custody
Use Section 71 with the bailee duties and the finder's related statutory rights.
Mistaken or coerced transfer
Use Section 72 and then check limitation, special statutory remedies and defences.
Remedy, proof and limits
The remedy reverses or values the relevant benefit. It does not punish the recipient or create the bargain the parties never made.
Depending on the section, relief may consist of reimbursement from property, repayment, return of a thing or reasonable compensation. The claimant should prove the transfer, the defendant's benefit, the absence of a valid legal basis for retention and the amount recoverable.
Claims may be affected by limitation, illegality, special statutory procedures, change of position, absence of free acceptance or the claimant's own primary liability. Quasi-contract should therefore be pleaded with the same precision as a consensual contract claim.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
State of West Bengal v. B.K. Mondal & Sons
AIR 1962 SC 779
Held: A Section 70 claim requires lawful conduct, non-gratuitous intention and enjoyment of the benefit. It is independent of enforcement of a formally defective government contract.
Why it matters: Use it as the leading framework for Section 70 and government receipt of non-gratuitous benefits.
Read the judgmentSales Tax Officer v. Kanhaiya Lal Mukundlal Saraf
AIR 1959 SC 135
Held: The word mistake in Section 72 includes mistake of law as well as mistake of fact, though later claims must also satisfy the governing statutory and restitutionary limits.
Why it matters: Use it for mistaken payment, then check limitation, special refund rules and unjust-enrichment concerns.

Questions students ask
Is a quasi-contract a real contract?
No. It lacks consensual formation. The law imposes a duty because the facts satisfy one of the statutory relations in Sections 68 to 72.
Is a minor personally liable for necessaries?
Section 68 permits reimbursement from the property of the incapable person. It does not turn the minor's promise into a personal contractual debt.
Can a volunteer recover under Section 69?
Not merely as a volunteer. The claimant must have a real interest in making the payment, while another person was legally bound to pay it.
Can Section 70 apply without a valid contract?
Yes. It creates an independent obligation when lawful non-gratuitous performance is voluntarily enjoyed. It compensates the benefit rather than enforcing the invalid agreement.
Does Section 72 cover mistake of law?
Kanhaiya Lal interpreted mistake to include law and fact. A present claim must still satisfy limitation, any special refund process and applicable restitutionary limits.
Does a finder of goods become the owner?
No. Taking custody creates bailee-like responsibilities and limited statutory rights, but the finder must care for the goods and return them to the true owner when identified.
