Quasi Contracts under Indian Contract Act

Quasi-Contract: An Obligation Created by Law, Not by Agreement

It is one of the most illuminating paradoxes in jurisprudence that the Indian Contract Act, 1872 — a statute built upon the architecture of offer, acceptance, and consent — devotes an entire chapter to obligations that arise without any of these foundational elements. Chapter V, significantly titled "Of Certain Relations Resembling Those Created by Contract," steers clear of the phrase "quasi-contract" altogether, yet its five sections — 68 to 72 — embody the very essence of what the common law world has long called quasi-contractual liability. The Act's deliberate avoidance of the term is itself instructive: the drafters understood that what these provisions created was not a contract in any true sense, but a law-imposed duty to prevent unjust enrichment.

The Nature of a Quasi-Contract

A contract, in its classical conception, is a creature of consent — it springs from the meeting of two minds, from offer and acceptance freely given. A quasi-contract is the polar opposite. As has been well stated in the commentaries on the Act, a quasi-contract is not a real contract at all; it is a "constructive contract" in which the law, without regard to the intention of the parties — and sometimes in the teeth of their clear dissent — imposes an obligation upon one person to pay money or restore property to another. The essential element of consent, which breathes life into every genuine contract, is simply absent here.

The Roman lawyers, who first grappled with this category, found quasi-contracts to be misfits — obligations that did not arise from contract (ex contractu) yet were not founded on a wrong (ex delicto) either. Justinian described them as obligations which "do not originate, properly speaking, in contract, but, as they do not arise from delict, seem to be quasi-contractual." In modern terms, they form a third category of law — distinct from both contract and tort — resting on the equitable doctrine of unjust enrichment. The maxim that captures it perfectly is nemo debet locupletari ex aliena jactura: no person should grow rich out of another's loss.

Lord Mansfield, the true architect of quasi-contractual thinking in the common law, articulated the principle with memorable clarity in the celebrated case of Moses v. Macferlan. He observed that if the defendant is under an obligation from the ties of natural justice to refund, the law implies a debt — a quasi-contractual obligation — as efficacious as if it arose upon a contract. Crucially, Lord Mansfield denied that this was a contract at all: the law implies a debt or obligation, not a promise. The Supreme Court of India, in Mulamchand v. State of Madhya Pradesh (AIR 1968 SC 1218), formally recognised quasi-contract or restitution as this "third category of law" distinct from contract and tort.

The unifying thread across all quasi-contractual situations is the obligation to make restitution — to restore what one has unjustly received at the expense of another. Sections 68 to 72 of the Act embody this principle.

Section 68: Supply of Necessaries to Persons Incapable of Contracting

The first quasi-contractual obligation the Act recognises concerns the supply of necessaries to a person who is legally incompetent to enter into a contract — a minor or a person of unsound mind — or to someone whom such a person is legally bound to support. Where such necessaries, suited to the condition of life of the incapable person, are supplied by another, the supplier is entitled to be reimbursed from the property of the incompetent person.

Two things are immediately striking about this provision. First, the liability is not personal — the minor or lunatic incurs no personal obligation. The claim lies only against their estate. Second, the liability does not arise ex contractu, but out of quasi-contract or restitutionary principles, as Mulla's commentary expressly states. The section follows the Privy Council's ruling in Mohori Bibee v. Dharmodas Ghose (1903 30 IA 114), which settled that a minor's agreement is absolutely void; the legislature then had to provide a separate statutory route for suppliers of genuine necessaries to seek reimbursement.

The word "necessaries" is deliberately broad. It is not confined to bare necessities of life such as food and clothing. It includes everything necessary to maintain the incompetent person in the state, station, and degree of life in which they move. In Nash v. Inman (1908 2 KB 1), the English court refused to hold a tailor entitled to recover for eleven fancy waistcoats supplied to a Cambridge undergraduate who was already amply clothed — because necessaries must be things actually required by the minor, and where they are already sufficiently supplied, further items lose their character as necessaries. Indian courts have followed this principle faithfully.

Necessaries have been held to include costs of litigation to protect the minor's property, money urgently needed to prevent a revenue sale of the minor's land, expenses for the marriage of a female minor (where Hindu law enjoins such marriage), and even medical and legal services. Money borrowed for Diwali celebrations, expenses on a pilgrimage of a purely spiritual nature, or moneys spent on the obsequies of a father have been held not to qualify.

Section 69: Reimbursement of a Person Who Pays Money Due by Another

Section 69 covers a situation of elegant simplicity. Where a person is legally bound to pay money, and another person — who has an interest in that payment being made — actually makes the payment, the latter is entitled to be reimbursed by the former.

The section's illustration is instructive: B holds land in Bengal under a lease from A, the zamindar. The revenue payable by A to the Government falls into arrears, and the Government advertises the land for sale — a sale that would annul B's lease. B, to protect his own interest, pays the government the sum due from A. A is bound to make good to B the amount so paid. The law creates an obligation of reimbursement not because A and B agreed to it, but because justice demands it.

Three conditions must be met. First, the plaintiff must be genuinely interested in making the payment — not merely as a volunteer or out of sentiment, but because he has a lawful, existing interest which the payment serves to protect. In Govindram Gordhandas Seksaria v. State of Gondal (AIR 1950 PC 99), the Privy Council clarified that it is sufficient if the person who makes the payment honestly believes that his own interest requires it. Second, the plaintiff must not himself be legally bound to make the payment — otherwise it would be mere discharge of his own obligation. Third, the defendant must have been legally bound — not merely morally — to make the payment.

The courts have recognised co-mortgagors, co-owners, co-sharers, lessees, sub-lessees, sureties, and reversioners as persons who may have sufficient legal interest to attract this section. A mere stranger with no identifiable interest in the property cannot invoke Section 69.

Section 70: Obligation to Pay for Benefits of Non-Gratuitous Acts

Section 70 is the broadest and most important of the five provisions, and it reaches far beyond the analogous English common law rule. It provides that where a person lawfully does anything for another, or delivers anything to him, without intending to do so gratuitously, and that other person enjoys the benefit of it, the latter is bound to make compensation or restore the thing.

The Supreme Court, in State of West Bengal v. B.K. Mondal & Sons (AIR 1962 SC 779), laid down the three essential conditions with precision: (i) the act or delivery must be done lawfully; (ii) it must not be done with the intention of acting gratuitously; and (iii) the other person must enjoy the benefit thereof. All three must be established before Section 70 can be invoked. The claim under this section is not based on any subsisting contract — it is grounded, as the Supreme Court reiterated in Mulamchand v. State of Madhya Pradesh (AIR 1968 SC 1218), on that third category of law: quasi-contract and restitution.

The section's width is illustrated by its application to contracts that are void for non-compliance with constitutional requirements. Under Article 299 of the Constitution, contracts with the Government must be expressed to be made by the President or Governor and executed in the specified manner. Failure to comply renders the contract void. Yet, if the Government accepts the benefit of such work, Section 70 steps in to ensure the contractor is not left without remedy. This was affirmed in Piloo Dhunji Shaw Sidhwa v. Municipal Corporation of the City of Poona (AIR 1970 SC 1201), where spare motor parts were supplied to a Corporation whose contract did not comply with the Bombay Municipal Corporation Act. The Corporation was held liable to pay reasonable compensation under Section 70.

It is important to appreciate what Section 70 does not cover. It does not apply to services rendered purely gratuitously — as illustration (b) makes plain, where A saves B's property from fire intending to act without reward, no claim arises. Nor does it apply where services are rendered at the express request of another person, because that gives rise to an implied contract and falls under different principles entirely. A minor cannot be sued under Section 70 — this would be an indirect way of enforcing a void agreement, rendering Section 68 redundant.

Section 71: Responsibility of the Finder of Goods

Section 71 provides that a person who finds goods belonging to another and takes them into his custody is subject to the same responsibilities as a gratuitous bailee. There is no contract between the finder and the true owner — the owner has not asked the finder to take custody, and the finder may be a complete stranger. Yet the law imposes the obligations of a bailee upon the finder the moment he takes the goods into his possession.

As a quasi-bailee, the finder must take as much care of the goods as a person of ordinary prudence would take of his own property of the same bulk, quality, and value. He must take reasonable steps to locate and return them to the true owner, and he is entitled to retain the goods against all persons except the true owner. He may also claim a lien for the expenses of preservation and any reward that may have been offered. The liability arises only upon taking the goods into custody — Section 71 cannot be invoked against a person who merely knew of the goods but did not assume custody of them. In Union of India v. Mahammad Khan (AIR 1959 Ori 103), a defendant who had issued a public notice asking people to remove their goods from land he had leased was held not liable, since he had not taken the goods into his custody.

Section 72: Money Paid or Thing Delivered by Mistake or Under Coercion

Section 72 is grounded in the most ancient principle of equity: that what is received without right must be restored. It provides that a person to whom money has been paid, or anything delivered, by mistake or under coercion, must repay or return it.

The word "mistake" in this section received its definitive interpretation from the Privy Council in Shiba Prasad Singh v. Maharaja Srish Chandra Nandi (AIR 1949 PC 297): the mistake must refer to a payment which was not legally due and which could not have been enforced — the payer mistakenly believed the money was owing when in fact it was not. Crucially, this section extends to mistake of law as well as mistake of fact. The controversy over whether money paid under a mistake of law could be recovered was put to rest by the Privy Council in that very case, and the Supreme Court affirmed this interpretation in Sales Tax Officer v. Kanhaiya Lal Makund Lal Saraf (AIR 1959 SC 135), where a firm was allowed to recover sales tax paid on forward transactions after the levy was declared ultra vires by the Allahabad High Court.

"Coercion" in Section 72 is not confined to the technical definition in Section 15 — it covers any compulsion, any payment made under duress. The illustration in the section is itself telling: a railway company refuses to deliver goods to the consignee except upon payment of an illegal charge; the consignee pays to obtain his goods. He is entitled to recover the illegally excessive charge. The payment was not voluntary — it was extracted under the coercive pressure of withholding what was rightfully his. Indian courts have extended this logic to payments made under threat of execution sale, payments to secure the release of a wrongfully detained person, amounts paid to avoid an illegal attachment, and electricity charges paid to avert disconnection.

However, a payment made with full knowledge of the facts and voluntarily cannot be recovered under this section. The mistake must be genuine — a lack of knowledge that, had it been present, would have prevented the payment entirely.

The Unifying Principle

What binds these five diverse situations together is the principle articulated by Lord Wright in the House of Lords in Fibrosa Spolka Akcyjna v. Fairbairn Lawson Combe Barbour Ltd (1943 AC 32), which the Mulla commentary adopts as the foundation of this entire chapter: "Any civilised system of law is bound to provide remedies for cases of what has been called unjust enrichment or unjust benefit, i.e., to prevent a man from retaining the money of, or some benefit derived from, another which it is against conscience that he should keep."

The Indian Contract Act, through Sections 68 to 72, achieves precisely this — not through the fiction of an implied promise, not through any meeting of minds, but through a direct, statutory imposition of an obligation by law. It is in this sense that a quasi-contract is, as the proposition demands, not a contract at all. It is an obligation which the law creates — in the language of the Act, a certain relation resembling one created by contract, but deriving its force not from consent, but from the imperatives of justice itself.
