Question

Write short notes on:
(a) Quasi-Contract.
(b) Contingent Contract.

Answer 1

Quasi Contract
Obligation created by law for reasons of justice and fairness. The doctrine of quasi contract is based upon the principle that a party must pay for a benefit he desired and received under circumstances that render it inequitable for him to retain it without making compensation. For example, a car owner brings his car in for brake repairs. The mechanic fixes the brakes and in doing so he also fixes a separate part of the axle that has a direct relationship to the car's ability to brake correctly. Although the axle repair was not specifically contracted for, a quasi contract is implied for which the owner must pay the mechanic.

Contingent Contract
“A contingent contract is a contract to do or not to do something, if some event, collateral to such contract does or does not happen.” Thus it is a contract, the performance of which is dependent upon, the happening or non-happening of an uncertain event, collateral to such contract.
Illustration A contract to indemnify B upto Rs20,000, in consideration of B paying Rs1,000 annual premium, if B’s factory is burnt. This is a contingent contract.
