"Quantum meruit" literally means "as much as he has earned." It's the law's answer to a very practical problem: someone has genuinely worked, or supplied something of value, but there's no contract price to fall back on — because the contract was void, was broken, or never fixed a price at all.
Ordinary contract remedies assume there is a working contract with a fixed price to enforce. Quantum meruit exists for the gap cases — where genuine work or value has changed hands, but the usual contractual price mechanism has broken down or never existed. Rather than let one party keep the benefit for nothing, the law orders payment of a reasonable sum for what was actually given.
Quantum meruit is a claim for reasonable remuneration for work done or goods supplied, calculated on the value of what was actually provided rather than any originally agreed contract price. It is restitutionary in character — closely related to the quasi-contractual principle of unjust enrichment already seen in Sections 68–72 — rather than a claim for lost profits or expectation damages.
Section 65 provides that when an agreement is discovered to be void, or when a contract becomes void, any person who has received any advantage under it is bound to restore it, or to make compensation for it, to the person from whom he received it. Where the "advantage" is work already performed rather than money or goods, courts award its reasonable value — a quantum meruit sum — under this same restitutionary logic.
If a party has begun performing a contract in good faith, and the other party's own breach (wrongful termination, refusal to cooperate, preventing access to complete the work) stops the contract being completed, the innocent party is not limited to only claiming damages. They may instead choose to claim quantum meruit for the reasonable value of the work already done up to the point performance was prevented.
Where a contract is divisible into separate parts, and one party has completed some of those parts while the other side has knowingly accepted and enjoyed the benefit of that partial performance, a quantum meruit claim is available for the parts actually completed — even though the whole contract was never finished.
Sometimes parties never fix a price at all — a professional is asked to "just help out," or begins work on the understanding that payment will be sorted out later. Where services of this kind are rendered and knowingly accepted, the law implies an obligation to pay a reasonable sum for them.
Craven-Ellis v. Canons Ltd. (1936) 2 KB 403 — the claimant was appointed managing director of a company under an agreement fixing his remuneration, but his own appointment turned out to be invalid from the start because neither he nor the other directors held the share qualification required by the company's articles — meaning no valid contract of employment ever existed. He nonetheless sued for the reasonable value of the services he had genuinely rendered to the company. The court awarded him quantum meruit, holding that the claim did not depend on there being any valid contract at all — it rested on an obligation implied by law to pay for services knowingly accepted, entirely independent of contract.
Quantum meruit is not a way to escape a bad bargain. If a valid, subsisting contract still governs the relationship, a party cannot simply abandon its agreed price because performance turned out to be more expensive or less profitable than expected, and then demand a "fairer" quantum meruit sum instead.
Alopi Parshad & Sons Ltd. v. Union of India, AIR 1960 SC 588 — the appellants were procuring agents supplying goods to the government under a wartime agency contract at agreed rates. When prices rose sharply, they claimed enhanced remuneration on a quantum meruit basis for the remaining period of the contract, arguing the original rates no longer reflected fair value. The Supreme Court rejected the claim, holding that so long as a contract validly subsists between the parties, they must abide by its terms — quantum meruit has no role to play while an enforceable contract still governs the same work.
| Basis | Quantum Meruit Available | Quantum Meruit Not Available |
|---|---|---|
| Contract status | Void, discharged by the other side's breach, or never fixed a price | Valid and still subsisting between the parties |
| What is claimed | Reasonable value of work/goods actually given | A "fairer" price to replace the agreed one |

An interior designer, Kavya, is engaged to redesign a five-room office under an oral understanding that she will be "paid fairly" once the work is done — no fixed fee was ever agreed. She completes three rooms to a high standard, and the client, satisfied, uses those rooms immediately, before terminating the engagement without cause before the remaining two rooms are touched. Kavya can claim quantum meruit for the reasonable value of the three completed rooms — the divisible-contract and no-fixed-price grounds both apply here — even though no contract price was ever fixed and the engagement ended before full completion.
