Promissory Estoppel
Definition
A legal doctrine that makes a promise enforceable even without a formal contract, when one party reasonably relied on the promise to their detriment. If someone made you a clear promise, you acted on it in a way that was reasonable, and you suffered a loss because of that reliance — you may have a claim even though no contract was signed.
In Practice
A company verbally promises a contractor that they'll be awarded a $500,000 renovation project, asking the contractor to 'start preparing.' The contractor turns down other jobs, hires additional crew, and purchases materials — investing $80,000 in reliance on the promise. The company then gives the project to someone else. Even without a signed contract, the contractor may recover their $80,000 in reliance damages through promissory estoppel because the company's promise was clear, the contractor's reliance was reasonable, and the loss was foreseeable.

Frequently asked questions about promissory estoppel
Four elements: (1) A clear and definite promise, (2) the promisor should have reasonably expected the promisee to rely on it, (3) the promisee actually relied on the promise to their detriment (took action or refrained from action), and (4) injustice can only be avoided by enforcing the promise. All four must be present. Vague promises ('we'll probably work together someday') and unreasonable reliance ('I quit my job because you said you liked my resume') won't meet the standard.
