Unjust Enrichment Information

**Unjust Enrichment** is not based on a written or oral contract but on the idea that one should not profit unfairly from another’s efforts or resources. It typically arises when one party provides goods, services, or payments under circumstances where compensation was reasonably expected but not received. For example, if a contractor improves a property under a mistaken belief of payment, the property owner may be required to reimburse the value of the benefit received. Unjust enrichment serves as a remedy when no valid contract exists but fairness dictates repayment. Courts evaluate factors such as benefit received, expectation of payment, and lack of lawful basis for the enrichment.

Florida Legal Definition

Under **Florida law**, **Unjust Enrichment** is a recognized equitable cause of action used to prevent one party from unfairly retaining benefits conferred by another. To establish a claim for unjust enrichment in Florida, the plaintiff must prove:
1. The plaintiff conferred a benefit upon the defendant.
2. The defendant knew of the benefit.
3. The defendant accepted or retained the benefit.
4. It would be inequitable for the defendant to retain the benefit without paying fair value.
These principles are outlined in Florida case law, including *Hillman Construction Corp. v. Wainer*, 636 So. 2d 576 (Fla. 4th DCA 1994). The remedy is restitution—requiring the defendant to return or pay for the value of the benefit unjustly retained.

How It’s Used in Practice

In practice, **Unjust Enrichment** claims are common in Florida civil and contract disputes where no enforceable agreement exists. For example, if a party mistakenly pays another’s debt or provides services without a written contract, they may seek restitution under this doctrine. Florida courts apply unjust enrichment principles in construction, business, and property disputes to ensure fairness. Attorneys often plead unjust enrichment as an alternative claim when contract validity is uncertain. This allows the wronged party to recover the value of benefits provided even without a formal agreement.
