contract law · claim
Promissory estoppel is a doctrine in contract law that allows a party to recover on a promise made, even when a legal contract does not exist, if they have relied on that promise to their detriment. This principle aims to prevent injustice resulting from reliance on a non-enforceable promise.
The promise made must be clear, unambiguous, and definite in nature, conveying a commitment.
What to prove: The promise must be shown to be specific enough, detailing the nature of the commitment.
The promisee must have relied on the promise in a way that is reasonable and foreseeable.
What to prove: Evidence must establish that the promisee acted upon the promise, shaping their behavior or decisions based on it.
The reliance on the promise must result in a significant detriment or injury to the promisee.
What to prove: It must be demonstrated that the promisee suffered a loss or a disadvantage due to their reliance on the promise.
Enforcement of the promise is necessary to avoid an unjust result that arise if the promise is not honored.
What to prove: It must be shown that failure to enforce the promise would lead to an unfair or unjust outcome for the promisee.
The burden of proof lies with the promisee (the party claiming promissory estoppel), and the standard is typically 'preponderance of the evidence.'
Students should be prepared to evaluate fact patterns that involve reliance on promises and consider how courts have applied the elements of promissory estoppel to arrive at their decisions.
