Contract vs. Quasi Contract: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on March 2, 2024
A contract is a legally binding agreement between parties with mutual consent, whereas a quasi contract is a legal obligation imposed by law in the absence of an agreement to prevent unjust enrichment.

Key Differences

A contract is a formal agreement between two or more parties, typically involving a mutual exchange of promises that is legally enforceable. In contrast, a quasi contract is not a real contract but a legal construct that courts impose to produce equitable results in certain situations where no actual contract exists.
Contracts require elements like offer, acceptance, intention to create legal relations, and consideration to be valid. Quasi contracts, however, are formed not through the consent of parties but by law to avoid unjust enrichment of one party at the expense of another.
In a contract, parties have the freedom to determine the terms and conditions mutually agreed upon. In the case of a quasi contract, the terms are imposed by law and are based on the principle of equity and fairness, not on the parties’ agreement.
Contracts are based on the parties' intentions and can be oral or written, whereas quasi contracts are strictly judicial constructs, never agreed upon but imposed to prevent injustice.
Breach of a contract results in remedies such as damages, specific performance, or rescission based on the terms of the contract. However, under a quasi contract, the remedy typically involves restitution or compensation for the value of benefits unjustly received.
