This section defines terms used in the Act. A proposal, once accepted, becomes a promise. Anything done, not done or promised at the promisor's desire is called consideration for the promise. A contract is an agreement enforceable by law, and an unenforceable agreement is void. A voidable contract is enforceable at the choice of some parties but not others.
