Exploring Quasi Contracts and Their Legal Implications

Picture this: a delivery company drops off ten sacks of premium basmati rice at the wrong address. The homeowner, instead of returning them, quietly uses the rice for a family wedding feast. No agreement was signed, no offer was made, no acceptance given. Yet the law says this homeowner still owes the delivery company money. This is the quiet, practical power of a quasi contract, a legal tool that exists precisely for situations where fairness demands payment even when a formal contract never existed.

For commerce students, quasi contracts often get treated as a footnote after the “real” chapters on offer, acceptance, and consideration. That is a mistake. Quasi contracts sit at the heart of how Indian business law handles fairness in messy, real-world transactions, from mistaken bank transfers to government construction disputes. Let us break down what they are, where they come from, and why every business student should understand them.

What exactly is a quasi contract? 🔗

A quasi contract is not actually a contract in the traditional sense. There is no offer, no acceptance, and often no intention by either party to enter into an agreement. Instead, courts treat certain relationships as if a contract existed, purely to prevent one party from being unjustly enriched at another’s expense. This is why quasi contracts are also called contracts implied in law, or constructive contracts, as opposed to contracts implied in fact, which still involve genuine mutual consent, just not expressed in words.

The guiding principle behind quasi contracts is the doctrine of unjust enrichment, rooted in the old legal maxim that no one should grow rich at another person’s cost. If you have benefited from someone else’s money, goods, or labour without a valid legal basis, the law steps in and creates an obligation for you to compensate them, regardless of whether you ever intended to enter into a contractual relationship.

The legal foundation: Sections 68 to 72 🔗

In India, quasi contracts are not defined as a single concept but are instead built out of five distinct situations laid out in Chapter V of the Indian Contract Act, 1872. This chapter is titled “Of certain relations resembling those created by contract,” a fairly accurate description of what it does. Each of the five sections addresses a different scenario where the law imposes liability despite the absence of a formal agreement.

Section 68: Necessaries supplied to someone incapable of contracting 🔗

Minors and persons of unsound mind cannot enter into binding contracts in India. But what happens when someone genuinely needs food, clothing, medical care, or shelter, and a shopkeeper or supplier provides these necessaries in good faith? Section 68 allows that supplier to recover the cost, not from the incapable person personally, but from that person’s property or estate. The idea is simple: essential goods and services should not go unpaid for just because the recipient lacked contractual capacity.

Section 69: Payment made on behalf of another 🔗

Sometimes one party is legally bound to pay a sum, such as a tax or a statutory due, but fails to do so, forcing another party with a genuine interest in the matter to pay it instead to avoid loss. Section 69 lets the person who made the payment recover it from the party who was originally liable. A common example involves paying someone else’s overdue property tax to prevent an auction of jointly used land.

Section 70: Obligation for non-gratuitous acts 🔗

This is arguably the most litigated of the five provisions. It applies when a person lawfully does something for another, or delivers something to them, without intending to do it for free, and the other person voluntarily accepts and enjoys the benefit. In such cases, the person receiving the benefit must compensate the person who provided it. Courts have applied this section widely, including in disputes involving government bodies that benefited from construction work performed without a technically valid contract, as detailed further below.

Section 71: Responsibility of a finder of goods 🔗

If you find someone else’s lost property and take it into your custody, the law treats you much like a bailee, meaning you owe the same duty of reasonable care that a person would owe if they had borrowed the goods under an actual contract. You cannot simply keep the item or use it carelessly; you are obligated to try to locate the true owner and look after the property responsibly in the meantime.

Section 72: Money paid or goods delivered by mistake or coercion 🔗

This section is especially relevant in the age of digital payments. If money is transferred to the wrong account by mistake, or if a payment is extracted through coercion, the recipient is bound to repay or return it. According to iPleaders’ analysis of quasi-contractual obligations, this provision has repeatedly been used by Indian courts to order refunds in cases involving accidental bank transfers and duplicate payments, since retaining money that was never rightfully owed amounts to unjust enrichment.

A landmark case that shaped Section 70 🔗

Legal provisions come alive through case law, and few cases explain Section 70 better than State of West Bengal v. B.K. Mondal & Sons, decided by the Supreme Court of India in 1961. A contractor built temporary storage godowns for the state government’s civil supplies department at the request of a government officer. The problem was that the contract had never been formally executed in the manner required under the Government of India Act, meaning there was no valid, binding agreement on paper.

The government then refused to pay, arguing that no valid contract existed. The Supreme Court disagreed with the government’s defence. As explained in a case summary from Drishti Judiciary, the court held that the absence of a formally valid contract did not prevent the contractor from claiming compensation under Section 70, since the government had knowingly accepted and used the construction, and the work was clearly not intended to be free. The judgment established that a body as large as the state cannot escape a Section 70 claim simply by hiding behind procedural technicalities, especially when it has demonstrably benefited from someone else’s labour.

This case is frequently cited because it shows that quasi contracts are not a minor academic curiosity. They can determine whether a government agency, a private company, or an individual has to pay for work or goods they have already consumed the benefit of, even when the paperwork fails.

How quasi contracts differ from real contracts 🔗

Students often confuse quasi contracts with implied contracts, but the two are conceptually distinct. An implied contract still requires genuine consent between the parties, just expressed through conduct rather than words. A quasi contract requires no consent at all; it is imposed entirely by the court to achieve a fair outcome.

As Legal Service India notes in its analysis of quasi contracts, these obligations rest on principles of equity, justice, and good conscience rather than the will of the parties, which is precisely why courts can enforce them even when no agreement was ever discussed.

Why this matters for commerce and business students 🔗

Understanding quasi contracts is not just an academic exercise for a law paper. Businesses regularly encounter situations that trigger these provisions. A vendor who supplies goods to a company based on a purchase order that later turns out to be technically defective, a logistics firm that delivers to the wrong warehouse, or an accountant who processes a duplicate vendor payment, all of these scenarios can invoke Sections 68 to 72.

For anyone entering finance, accounting, supply chain, or general management roles, recognising when a quasi-contractual obligation applies helps in assessing financial risk, structuring recovery claims, and understanding why certain payments cannot simply be written off as a loss. Businesses that deal with the government or public sector bodies, in particular, should pay close attention to the B.K. Mondal precedent, since it shows courts are willing to hold even state entities accountable for benefits received outside a formally valid contract.

The bigger picture: equity filling the gaps of contract law 🔗

Contract law is built on the idea of consent, two or more parties freely agreeing to specific terms. But real life does not always fit neatly into that framework. People make mistakes, emergencies arise, and benefits get transferred without a formal agreement in place. Quasi contracts exist precisely to handle these gaps, ensuring that the absence of a signed document does not become a shield for one party to profit unfairly at another’s expense.

This is what makes the concept genuinely useful beyond the exam hall. It reflects a broader principle running through Indian commercial law: fairness and restitution matter even when the strict formalities of contract formation are missing.

What do you think? If you accidentally received a large sum of money in your bank account due to a technical glitch, would you consider it “found money,” or do you think Section 72 should apply the moment you notice the mistake? And should government bodies be held to a stricter standard than private individuals when it comes to quasi-contractual liability, given how the B.K. Mondal case played out?
