Consideration Requirements for Enforceable Contracts

Consideration is the exchange element that distinguishes enforceable contracts from mere promises. Tested heavily on the bar exam and in 1L contracts courses, it requires a bargained-for exchange of legal value. Understanding what counts—and what doesn't—as valid consideration is essential for contract analysis.

Frequently Asked Questions

What is the difference between consideration and a gift?

Consideration requires a bargained-for exchange—each party gets something of value. A gift is a one-sided promise with no return exchange, making it unenforceable without a deed.

  • Gifts: no legal obligation
  • Consideration: creates binding obligation

Can nominal consideration (e.g., $1) support a contract?

Generally yes under traditional doctrine—courts don't evaluate adequacy of consideration. However, token consideration for a grossly unequal exchange may signal a disguised gift and be unenforceable in some jurisdictions.

What happens if consideration fails?

If consideration is absent or fails, the contract is generally unenforceable as a simple promise. Courts may still enforce it under promissory estoppel if the promisee reasonably relied on the promise to their detriment.
