Promissory Estoppel
Promissory estoppel is the second way a promise can become binding without consideration.
6. Promissory Estoppel
“A promise which the promisor should reasonably expect to induce action or forbearance on the part of the promisee or a third person and which does induce such action or forbearance is binding if injustice can be avoided only by enforcement of the promise. The remedy for breach may be limited as justice requires.” Restatement (Second) of Contracts § 90.
- This method of enforcing a promise is called “promissory estoppel.”
- Test-takers need not recall the precise words of the Restatement provision, but they should know the four elements a party must establish to recover under this theory:
- That a promise existed;
- That the promisor should have reasonably expected the promise to induce action or forbearance by the promisee;
- That the promise did induce action or forbearance; and
- That injustice would result from failure to enforce the promise.
- Factors that courts consider in determining whether injustice would result include:
- The reasonableness of the recipient’s reliance,
- The extent of the reliance, and
- The clarity and certainty of the promise made.
Promissory estoppel makes a promise binding without consideration by substituting the promisee's reasonable reliance for the bargained-for exchange. A plaintiff must establish a closed list of four elements, and even then the remedy may be limited as justice requires.
Promissory estoppel is the second way a promise can become binding without consideration. Where the bargained-for exchange supplies the binding force in an ordinary contract, promissory estoppel substitutes the promisee's reasonable reliance for that exchange. There is no bargain here. The promisor gets nothing in return and asks for nothing in return; the promise becomes enforceable because the promisee reasonably relied on it and would suffer an injustice if the promise were now ignored.
- 1A promise actually existed.
- 2The promisor should have reasonably expected that promise to induce action or forbearance by the promisee. That expectation is judged objectively from the promisor's vantage point, not from whether the promisor secretly intended to be bound.
- 3The promise did in fact induce that action or forbearance. The reliance has to be real and traceable to the promise, not something the promisee would have done anyway.
- 4Injustice would result if the promise were not enforced.
In weighing that last element, courts consider several factors, and this list is illustrative rather than exhaustive: how reasonable the recipient's reliance was, how extensive that reliance was, and how clear and certain the promise was. These are factors a court weighs on the injustice question, not extra elements a plaintiff must independently prove.
One more point on the back end: even when all four elements are satisfied, the remedy may be limited as justice requires. Reliance damages, not full expectation, may be the appropriate measure. So promissory estoppel can make a promise binding, but it does not automatically hand the promisee everything the promise would have been worth had it been a bargained-for contract.

Miss any one and the theory fails.
No bargain needed.
Promissory estoppel is a consideration substitute.
If a question turns on what the promisor got in return, it is testing ordinary consideration, not this theory.
The injustice factors are an 'include' list, not a closed one: reasonableness of the reliance, extent of the reliance, clarity and certainty of the promise.
They guide the injustice inquiry; they are not separate elements.
Remedy is capped by justice.
Even a winning plaintiff may get only reliance, not full expectation, because the remedy may be limited as justice requires.
Expectation is judged from the promisor's side and objectively: should the promisor reasonably have foreseen reliance?
The promisor's private intent to be bound is beside the point.
A charity announces a building campaign, and a donor signs a written pledge promising fifty thousand dollars toward construction. The donor knows, and says, that the charity plans to use pledges like this one to line up a contractor and break ground. In reliance on the pledge and others like it, the charity signs a construction contract and begins work. The donor then refuses to pay, arguing the charity gave nothing in return for the pledge. The charity sues to enforce the promise.
All four elements are met, so the pledge is binding under promissory estoppel even though the charity gave no bargained-for consideration. Note the donor's 'I got nothing in return' argument is exactly the point of the theory, not a defense to it. The remedy, however, may be limited as justice requires, so the charity's recovery could be measured by what it committed in reliance rather than by the full face amount of the pledge.
A 'No' answer resting on a true but irrelevant fact, most often 'the promisor received nothing in return' or 'there was no bargained-for exchange,' or pointing to reliance the promisee would have undertaken anyway.
Reliance substitutes for consideration, so the lack of a bargain is not a defense; and the inducement element requires reliance actually caused by the promise, not coincidental conduct.An answer that adds or misstates an element: that the promisor must have expressly intended to be bound, that actual reliance alone suffices, or that an injustice factor (reasonableness, extent, clarity) is itself a separate required element.
The element is that the promisor should reasonably have expected reliance, judged objectively; all four elements must be met, and the injustice factors only inform the injustice inquiry.An answer that imports a different doctrine: bargained-for consideration, a benefit-to-the-promisor requirement, contract modification, or a statute-of-frauds analysis.
Promissory estoppel is its own four-element theory; it needs no exchange and no benefit, and whether it can defeat a statute-of-frauds defense is outside the tested scope.An absolute: 'any promise relied upon is enforceable,' 'the court must award full expectation,' or 'a promise of this kind can never be enforced.'
Enforcement requires all four elements including injustice, and the remedy may be limited as justice requires, so neither automatic enforcement nor automatic full recovery follows.A 'Yes' that reaches the right outcome on the wrong ground, such as the existence of a signed writing or the promisee's good faith, rather than on reasonably expected and actual reliance plus injustice.
Name the operative ground, the four elements, not an incidental fact like a writing that the theory does not require.the stem hands you a promise made without any bargained-for exchange, then shows the promisee doing something, or giving something up, because of that promise, often with a pointed note that the promisor 'got nothing in return.' The moment you see a gratuitous promise plus reliance, stop reaching for ordinary consideration and run the four-element promissory-estoppel check: (1) a promise, (2) the promisor should reasonably have expected it to induce action or forbearance, (3) it did induce action or forbearance, and (4) injustice without enforcement.
If all four are present, the promise is binding even with no bargain, and any answer that says it fails for lack of consideration is a distractor.
If reliance was not reasonably foreseeable, or the promisee would have acted anyway, or there is no injustice, the theory fails.
And remember the remedy may be limited as justice requires, so a winning plaintiff is not automatically entitled to the full value of the promise.
An uncle promised his niece, in a signed note, that he would pay her tuition for an additional year of graduate study so that she could finish her degree. The uncle knew the niece was deciding whether to enroll and that the cost was beyond her means without his help. Relying on the promise, the niece enrolled, signed a lease near the school, and turned down a paying job that conflicted with her class schedule. The uncle then refused to pay, pointing out that the niece had given him nothing in return for his promise. The niece sued to enforce the promise.
Is the niece likely to succeed in enforcing the uncle's promise?
A company recruited an accountant who held a secure job in another city. The company's hiring manager promised the accountant a position starting the following month and told her to give notice and relocate so she could begin on time. The hiring manager knew the accountant would have to quit her current job and move to take the offer. The accountant resigned her position, sold her home, and moved across the state. Before her start date, the company withdrew the offer. The accountant had received no signed employment agreement and no pay, and she sued the company on a promissory-estoppel theory.
Which of the following best explains why the company's promise may be enforceable even without consideration?
At a casual dinner, a wealthy guest remarked to a friend who ran a small bakery that he might someday help her expand if business stayed strong, though he named no amount, no time, and no terms. The guest had no idea the friend was contemplating a major purchase. Without telling the guest, the friend took the comment as a commitment, signed a costly lease for a second location, and bought new equipment. The guest later declined to contribute anything, and the friend sued him under a promissory-estoppel theory to recover what she had spent.
Is the friend likely to succeed against the guest?
A supplier promised a craftsman that it would deliver a specialized machine to him at no charge so that he could take on a large order, and the supplier knew the craftsman would gear up his shop in reliance. The craftsman, relying on the promise, hired an assistant and turned away other work, spending a modest sum to prepare. The supplier never delivered the machine. Had the machine arrived, the craftsman would have earned a large profit on the order, but his actual out-of-pocket preparation costs were small. A court finds all four elements of promissory estoppel satisfied.
Which of the following best describes the remedy the court may award?
A landlord told a longtime tenant, who ran a shop in the building, that the landlord would soon repave the shared parking lot at the landlord's own expense to help the shop's customers. The landlord reasonably expected the tenant to keep operating in reliance, and the promise was clear. As it happened, the tenant had already decided months earlier, for unrelated reasons, to renew the lease and stay regardless of any repaving, and the tenant did exactly what it had always planned, changing nothing because of the landlord's statement. The landlord never repaved, and the tenant sued under a promissory-estoppel theory.
Is the tenant likely to recover against the landlord?
