Define: Quantum Meruit

The reasonable value of services provided, which a winning party may be able to recover from an opponent who broke a contract.

A payment for work completed under the terms of a breached contract (see: Breach of contract). Such an award may be made by the court if the contract is partially fulfilled (see: Part performance of contract).

Quantum meruit determines the amount to be paid for services when no contract exists or when there is doubt as to the amount due for the work performed but done under circumstances when payment could be expected. This may include a physician’s emergency aid, legal work when there was no contract, or evaluating the amount due when outside forces cause a job to be terminated unexpectedly. If a person sues for payment for services in such circumstances the judge or jury will calculate the amount due based on time and usual rate of pay or the customary charge, based on quantum meruit by implying a contract existed.
