"In order that there must be a contract concluded, undoubtedly, there must be a proposal made, which must be accepted. There must be consideration for the promise. The proposal must be accepted, which must be communicated, as already explained. The acceptance must be unqualified. This is an oversimplification of a complex process. We say this, as the parties can be said to have entered into a contract or a contract would be said to be concluded only when they are ad idem on all the essential terms of the contract. In other words, if the proposals containing the essential terms have been accepted, and the acceptance is communicated and, if the other conditions in Section 2 of the Indian Contract Act are complied with, viz. , that is there is consideration and the contract is enforceable in law, within the meaning of Section 2 of the Contract Act, it would lead to the creation of a concluded contract."
