# Promissory Estoppel

Promissory estoppel enforces a promise lacking consideration when the promisor should reasonably expect reliance, the promisee actually relies to their detriment, and injustice can only be avoided by enforcement.

## Definition

Promissory estoppel, codified in Restatement (Second) of Contracts section 90, serves as a substitute for consideration when enforcing a promise that would otherwise be unenforceable. It applies when a promisor makes a promise that they should reasonably expect will induce action or forbearance by the promisee, the promisee actually and justifiably relies on that promise, and injustice can only be avoided by enforcing the promise.

The doctrine originated in equity and gained prominence through cases where strict application of the consideration requirement would produce unjust results. It is most commonly invoked in the context of gratuitous promises, charitable subscriptions, promises made during negotiations, and employment contexts such as at-will offers. Courts have broad discretion in fashioning the remedy, which may be limited to reliance damages rather than full expectation damages.

Promissory estoppel is not a first-line theory of recovery; it is a fallback when consideration is absent. On an exam, you should analyze consideration first and turn to promissory estoppel only if consideration fails. The doctrine reflects the law's recognition that reasonable reliance on a promise can create obligations even outside the formal bargain framework, balancing freedom of contract against fairness to those who change their position in reliance on another's word.

## Elements

- A clear and definite promise by the promisor
- The promisor should reasonably expect the promise to induce action or forbearance
- The promisee actually and justifiably relies on the promise
- The promisee suffers a definite and substantial detriment
- Injustice can be avoided only by enforcement of the promise

## Key Case

Ricketts v. Scothorn, 57 Neb. 51 (1898)

## Landmark Cases

| Name | Citation | Significance |
| --- | --- | --- |
| Ricketts v. Scothorn | 57 Neb. 51 (1898) | Early landmark applying equitable estoppel to enforce a gratuitous promise where the promisee quit her job in reliance. |
| Hoffman v. Red Owl Stores | 26 Wis. 2d 683 (1965) | Extended promissory estoppel to pre-contractual negotiations, allowing recovery for reliance on promises made during franchise negotiations. |
| Feinberg v. Pfeiffer Co. | 322 S.W.2d 163 (Mo. Ct. App. 1959) | Enforced an employer's promise of a pension through promissory estoppel when the employee retired in reliance on the promise. |
| Charitable Subscriptions (Allegheny College v. National Chautauqua County Bank of Jamestown) | 246 N.Y. 369 (1927) | Cardozo found consideration in a charitable pledge but discussed promissory estoppel as an alternative basis, influencing the doctrine's application to charitable promises. |

## Exam Tips

- Always analyze consideration first; promissory estoppel is a fallback, not a primary theory.
- Remember that the remedy may be limited to reliance damages rather than full expectation damages—the court has discretion.
- Look for the reasonable expectation element: would a reasonable person in the promisor's position foresee that the promisee would rely?
- Charitable subscription cases often have relaxed requirements—note this if it appears on an exam.

## Common Mistakes

- Jumping to promissory estoppel without first analyzing whether valid consideration exists.
- Assuming promissory estoppel always yields full contract damages—courts often limit recovery to reliance damages.
- Forgetting that the promise must be clear and definite; vague statements of future intent are insufficient.

## Mnemonic Or Memory Aid

PRIDE: Promise, Reasonable expectation of reliance, Induced action, Detriment suffered, Enforcement needed to prevent injustice.
