Consideration and Promissory Estoppel: Ask Which Theory Is Doing the Work

# Consideration and Promissory Estoppel: Ask Which Theory Is Doing the Work

Students sometimes treat promissory estoppel as a softer version of consideration. The better approach is to analyze the theories separately. Consideration asks whether the promise was part of a bargained-for exchange. Promissory estoppel addresses certain promises that may be enforceable because of justified reliance even when ordinary consideration is absent.

Consideration requires a bargain

Look for the exchange: what did the promisor seek in return for the promise, and what did the promisee give or promise? A condition on receiving a gift is not automatically consideration merely because the promisee had to do something.

Past action usually creates a problem

Something already done before the promise ordinarily was not bargained for in exchange for that later promise. That is why past consideration is a common exam trap.

Promissory estoppel has its own elements

A typical formulation asks for a promise, reasonably foreseeable and actual reliance, and circumstances in which enforcement is necessary to avoid injustice. Follow the formulation taught in your course or jurisdiction.

Do not use estoppel before checking contract formation

If a valid contract already exists, ordinary contract doctrine may resolve the dispute. Promissory estoppel is often analyzed when consideration or contract formation is missing.

On an exam, label the theory before applying facts. 'Consideration' and 'reliance' are not interchangeable explanations for enforceability.
