Meaning
A legal doctrine prevents one party from retaining a benefit or profit at the expense of another in circumstances where it is unfair to do so. Under corporate and restitution law, unjust enrichment governs cases where funds or assets are transferred by mistake, fraud or an invalid contract. It establishes the obligation of the receiving party to restore the value of the benefit to the claimant.
The doctrine stops applying if the recipient can show they changed their position in good faith before being notified of the claim.
Restitution Rule
The judicial remedy focuses on the restoration of the benefit rather than the compensation of a loss. In disputes involving unjust enrichment, the court orders the defendant to return the specific property or pay a sum of money equivalent to the gain. This mechanism is frequently used in equity transactions when shares are mistakenly transferred to the wrong account.
It ensures that the balance of assets is corrected to reflect the true intentions of the parties.
Procedural Proof
A claimant must establish that the defendant received a benefit at the claimant’s expense and that the retention is unjust. This test does not require proof of wrongdoing or bad faith on the part of the recipient. The receipt of the value itself is sufficient to trigger the restitutionary obligation.
Limitation Margin
A defense against the claim arises if the recipient is a bona fide purchaser for value without notice.
