Quasi-contract
From Wikipedia, the free encyclopedia
A quasi-contract, also an implied-in-law contract, is a legal substitute for a contract. A quasi-contract is a contract that should have been formed, even though in actuality it was not. It is used when a court wishes to create an obligation upon a non-contracting party to avoid injustice.
Quasi-contracts are defined to be "the lawful and purely voluntary acts of a man, from which there results any obligation whatever to a third person, and sometime a reciprocal obligation between the parties." [1] In contracts, it is the consent of the contracting parties which produces the obligation; in quasi-contracts no consent is required, and the obligation arises from the law or natural equity, on the facts of the case. These acts are called quasi-contracts, because, without being contracts, they bind the parties as contracts do.
The defendant's liability under quasi-contract is equal to the value of the benefit conferred by the plaintiff. The value is the fair market value of the benefit and not necessarily the subjective value that the defendant enjoys. For example, accountant prepares tax-payer's taxes, finding a way to get him an unusually large refund. Tax-payer doesn't pay accountant. Assuming a court finds no contract, tax-payer is only liable for the fair market value of tax preparation services, which is not inflated up to account for the unusually large refund he enjoyed.
An example of a quasi-contract is the case of a plumber who accidentally installs a sprinkler system in the lawn of the wrong house. The owner of the house had learned the previous day that his neighbor was getting new sprinklers. That morning, he sees the plumber installing them in his own lawn. Pleased at the mistake, he says nothing, and then refuses to pay when the plumber hands him the bill. Will the man be held liable for payment? Yes, if it could be proven that the man knew that the sprinklers were being installed mistakenly, the court would make him pay because of a quasi-contract. If that knowledge could not be proven, he would not be liable.
