Quasi Contracts: When the Law Implies an Obligation

What Is a Quasi Contract?

A quasi contract (also called a contract implied-in-law or "quantum meruit" claim) is not actually a contract at all. It is a legal remedy created by courts to prevent one party from being unjustly enriched at another party's expense when no formal agreement exists between them.

How It Works

When someone receives a benefit from another person under circumstances where it would be unfair to keep it without paying, courts impose an obligation to compensate — as if a contract existed. The key elements are:

  1. One party conferred a benefit on the other
  2. The recipient was aware of the benefit (or should have been)
  3. Retaining the benefit without payment would be unjust

Common Scenarios

  • A contractor performs work based on a verbal understanding, but no written contract was signed
  • Emergency services are provided to someone who cannot consent (unconscious patient)
  • A person mistakenly improves the wrong property (building a fence on a neighbor's land by accident)
  • Work continues after a contract expires while the parties negotiate a renewal

Quasi Contract vs. Implied-in-Fact Contract

  • Implied-in-fact contract — the parties' conduct demonstrates they actually agreed to an arrangement
  • Quasi contract — no agreement existed at all, but the court imposes an obligation to prevent injustice

Limitations

  • The amount recoverable is typically the reasonable value of the benefit conferred, not necessarily what the claimant hoped to earn
  • A quasi contract claim generally cannot succeed if an express contract already covers the same subject matter
  • Volunteers who confer benefits without expectation of payment usually cannot recover
  • The benefit must have been conferred under circumstances that make retention unjust

When to Consult a Lawyer

Consider consulting an attorney if you provided valuable services or goods without a formal contract and the recipient refuses to compensate you.
