Some definitions are as follows:
Pollack: “a contract is an agreement creating and defining obligations between the parties".
Sir William Anson: “an agreement enforceable by law made between two or more persons, by which rights are acquired by one or more to acts or forbearance on the part of other or others."
Sec. 2(h) of contract Act provides "an agreement enforceable by law is a contract." thus a contract consists of two elements:
(a) Agreement (b) enforceability by law
