An equitable doctrine that permits enforcement of an oral contract or restitution for benefits conferred when a party has rendered part performance in reliance on the agreement. The doctrine satisfies the evidentiary purpose of the statute of frauds or creates an option contract that renders a unilateral offer irrevocable while performance continues. It applies when the acts are unequivocally referable to the contract and the performing party cannot be restored to the status quo without injustice.

Phuong Pham avoided an oral land contract on grounds of misrepresentation after paying two installments and taking preliminary steps toward development. The court awarded restitution of the payments because the part performance conferred a measurable benefit on the seller that could not be retained without unjust enrichment. Pavel Petrov, the seller, was required to return the funds even though the contract itself remained unenforceable.
Peter Park orally agreed to buy a parcel from Paige Porter for a fixed price. Park took possession, built a fence, and planted crops in reliance on the promise. The court enforced the oral contract under the part performance doctrine because the acts were unequivocally referable to the sale and Porter could not restore the status quo without injustice.
Pierce Patterson offered a bonus to the first subcontractor who completed paving work on a specified site. Drennan began the paving in reliance on the offer. The court held that the part performance created an option contract that prevented Patterson from revoking while Drennan continued toward completion.
Phoebe Park moved into a house and performed minor repairs after an oral promise that the property would pass to her on the owner's death. The court refused specific performance because the acts could be explained without reference to an ownership agreement and therefore did not constitute sufficient part performance.
Progressive Healthcare conveyed one tract to Premier Manufacturing under an oral agreement to exchange parcels. Premier took possession of the second tract and made improvements. The court enforced the exchange because Premier's possession and improvements supplied the part performance needed to remove the oral contract from the statute of frauds.
Precision Tools relied on an oral promise of an easement across neighboring land by installing utilities and grading a road. The court recognized the easement under the part performance doctrine because the improvements were made in direct reliance on the oral grant and could not be undone without substantial loss.
Courts require acts that are unequivocally referable to the contract, such as taking possession and making permanent improvements that cannot be explained without reference to an ownership agreement. Mere payment of money or minor repairs usually falls short because those acts can be consistent with a lease or license.

Yes. When an offer invites acceptance solely by performance, the offeree's beginning the invited performance creates an option that prevents revocation while the offeree continues in accordance with the offer's terms. The offeror's duty remains conditional on completion or tender of the full performance.

A party who avoids a contract on grounds such as misrepresentation or lack of capacity may recover the reasonable value of any benefit conferred by part performance or reliance. The performing party must generally return any benefit received, but is entitled to compensation for improvements made before avoidance.

No. Part performance satisfies the statute only for land-sale contracts. Contracts that cannot be performed within one year remain unenforceable despite partial performance because the statute's purpose of preventing disputes over long-term oral promises is not satisfied by acts that do not uniquely evidence the agreement.
