Consideration

Consideration is the concept of legal value in connection with contracts. It is anything of value promised to another when making a contract. It can take the form of money, physical objects, services, promised actions, abstinence from a future action, and much more. Consideration to create a legally enforceable contract entails a detriment to the promisee OR a benefit to the promisor. Under the notion of "pre-existing duties", if either the promisor or the promisee already had a legal obligation to render such payment, it cannot be seen as consideration in the legal sense.
