Gratuitous and Non-Gratuitous Acts — Compensation Under Section 70

A tradesman leaves goods at your house by mistake. You start using them anyway. Have you agreed to pay? Never — but Section 70 says you must anyway, and this post is about exactly when that duty kicks in, and when it doesn't.

1. Lawful Act

The person did something for, or delivered something to, another person — lawfully.

2. Not Gratuitous

The act was not intended as a gift — the person expected to be paid.

3. Benefit Enjoyed

The other person actually accepted or enjoyed the benefit of it.

All three must be present — miss even one, and Section 70 gives no remedy.

The Problem This Topic Solves

Section 68 and 69, covered in the previous post, deal with narrow situations — necessaries for an incapable person, and reimbursing an interested payer. Section 70 is the broader, general-purpose rule: whenever someone does something for you or delivers you something, not meaning it as a gift, and you knowingly accept the benefit, the law will not let you keep that benefit for free — even without any contract between you.

What Does Section 70 Say?

Section 70 provides: "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 make compensation to the former in respect of, or to restore, the thing so done or delivered."

Illustration (a): A, a tradesman, leaves goods at B's house by mistake. B treats the goods as his own. He is bound to pay A for them.

Gratuitous Acts Get Nothing — Illustration (b)

The second condition — that the act must not be intended gratuitously — is what separates a genuine Section 70 claim from a good deed the law simply will not reward. If you helped someone expecting nothing in return, Section 70 gives you nothing in return either.

Illustration (b): A saves B's property from fire. A is not entitled to compensation from B, if the circumstances show that he intended to act gratuitously.

Gratuitous vs. Non-Gratuitous Acts

Basis	Gratuitous Act	Non-Gratuitous Act
Intention	Done voluntarily, as a favour or gift, with no expectation of payment	Done expecting to be paid or compensated, even without a formal contract
Section 70 remedy	None — the person cannot later claim compensation	Available, once the other conditions are also met
Example	Rescuing a neighbour's goods from a fire out of goodwill	A contractor who completes government work believing a formal contract would follow

The Three-Part Test in Action — State of West Bengal v. B.K. Mondal & Sons

State of West Bengal v. B.K. Mondal & Sons, AIR 1962 SC 779 — the contractor constructed certain works for the government at the government's request, in the expectation that a formal contract would follow, but no valid contract was ever actually executed. The government, however, took over and used the completed structures. The Supreme Court held the government liable to pay compensation under Section 70, laying down the three conditions this post opens with: a lawful act done for another, not intended gratuitously, and the benefit knowingly accepted by that other person. The Court was clear that Section 70 does not require any contract at all — it is precisely for situations where no valid contract exists but one party has still benefited at another's expense.

Must Know

Section 70 has three conditions: a lawful act or delivery, not intended gratuitously, and the benefit knowingly enjoyed by the other person
If the act was intended as a gift, Section 70 gives no remedy at all — this is the gratuitous/non-gratuitous line
State of West Bengal v. B.K. Mondal & Sons (AIR 1962 SC 779) is the leading case establishing the three-part test, in a case with no valid contract at all

Should Know

Section 70 is often the fallback remedy when a contract turns out to be void or was never validly formed, but one side has already benefited
"Enjoys the benefit" requires the other person to have some choice in the matter — a benefit forced on someone who could not refuse it does not automatically attract Section 70

A Practical Example

A private firm repairs a stretch of a municipal road under an informal understanding with a local officer, expecting the municipality to pay the standard contractor rate once the work is verified. No formal contract is ever signed, but the municipality opens the road to traffic and relies on the repair for months. Since the firm's act was lawful, was never intended as a gift, and the municipality knowingly accepted and used the benefit, the firm is entitled to compensation under Section 70 — the same reasoning the Supreme Court applied in B.K. Mondal.

Quick Revision Points

Section 70 = compensation for a lawful, non-gratuitous act whose benefit the other person knowingly enjoyed
Three conditions: lawful act, not gratuitous, benefit enjoyed — all three required
Gratuitous acts (illustration b) get no compensation, however valuable the benefit
State of West Bengal v. B.K. Mondal & Sons — Section 70 applies even where no valid contract ever existed
This is the general-purpose quasi-contract rule; Sections 68 and 69 are narrower, specific situations already covered
