Common questions
Frequently Asked
4
How does detriment to the promisee differ from benefit to the promisor?+
Detriment to the promisee focuses on the legal right the promisee gives up or the duty assumed. Benefit to the promisor focuses on the advantage received by the promisor. Either can satisfy the consideration requirement under traditional doctrine.
Does forbearance from a legal right always qualify as detriment?+
Yes when the forbearance is bargained for and induced by the promise. Refraining from drinking, smoking, or pursuing litigation at the promisor's request has been held sufficient even without economic loss to the promisee.
Why does the Restatement Second of Contracts largely abandon the detriment test?+
The drafters found that the bargained-for exchange requirement alone adequately identifies enforceable promises. Adding a separate detriment or benefit inquiry tended to introduce unnecessary confusion without changing outcomes.
Can detriment exist when the promisee suffers no financial loss?+
Yes. The legal test looks to the surrender of a right the promisee was free to exercise, not to measurable economic harm. Forbearance from lawful conduct requested by the promisor supplies the required detriment.
