Quantum Meruit - Examples

Examples

I. An example used in United States law schools is usually as follows:

Person A (plaintiff in this hypothetical) tells neighbor B (defendant) that he is going to build a wall on their property that will give a benefit to both A and B; A implies that it would be cheaper for both of them if A performs the labor instead of hiring a professional. B agrees that the wall should be built, but no price is negotiated. A builds the wall, and then asks B to compensate him for the benefit of the wall that he conferred on B (usually half the value of the wall). B refuses. A is entitled to some compensation based on quantum meruit. This is because there was an implied promise between A and B, which is derived from contract law, because A was acting under the assumption that B would pay for part of his services (see Estoppel). The winning of the case will be directed as an assumpsit on a quantum meruit. Day v. Caton, 119 Mass. 513 (1876).

In Canada, 'quantum meruit' is not based on contract law but rather depends on equitable principles of unjust enrichment. Estoppel allows an implied promise to act as a shield against litigation but never a sword. Therefore an implied promise would not create a cause of action. Instead 'quantum meruit' is based on the need to prevent the neighbor from unjustly enriching himself by allowing the fence builder to proceed with the work based on an assumption that he would be compensated.

II. Quantum meruit can also apply where there is a breached contract.

A contractor is contracted to work on a school. The contractor does some work but then quits (breach of contract). The contractor is entitled to be paid for the services he has already provided for the school on the basis of quantum meruit (however the school may be entitled to damages arising out of the need to look for a new contractor).

III. If a plaintiff is prohibited from completing work based on a long term service contract where other contracts have been negotiated, the plaintiff may ask a court to determine a judgment based on the amounts that the defendant benefited. Third parties may also bring actions against the plaintiff.

IV. A Promoter enters into a long term service contract with a Theatre to exclusively present events for a specified period. The promoter books events and contracts with others to perform during the entire period but alleges that the theatre is unsafe. The Promoter withholds payments until the theatre is made safe. The Theatre performs no repairs. Instead the Theatre terminates the entire service contract before the benefit of the events occurs to the plaintiff and refuses to repair the theatre. After the contract is terminated, the theatre operates the events negotiated by the promoter and gains a significant benefit but does not pay the promoter anything. The theatre also cancels some events without cause. A court determines that the promoter is entitled to an assumpsit on a quantum meruit.
