Section 7 in The Indian Contract Act, 1872
Title: Acceptance must be absolute.
In order to convert a proposal into a promise, the acceptance must—
(1) be absolute and unqualified;
(2) be expressed in some usual and reasonable manner, unless the proposal prescribes the manner in which it is to be accepted. If the proposal prescribes a manner in which it is to be accepted, and the acceptance is not made in such manner, the proposer may, within a reasonable time after the acceptance is communicated to him, insist that his proposal shall be accepted in the prescribed manner, and not otherwise; but if he fails to do so, he accepts the acceptance.
Title: Acceptance by performing conditions, or receiving consideration.
Performance of the conditions of a proposal, or the acceptance of any consideration for a reciprocal promise which may be offered with a proposal, is an acceptance of the proposal.
Title: Promises, express and implied.
In so far as the proposal or acceptance of any promise is made in words, the promise is said to be express. In so far as such proposal or acceptance is made otherwise than in words, the promise is said to be implied.
Title: What agreements are contracts.
All agreements are contracts if they are made by the free consent of parties competent to contract, for a lawful consideration and with a lawful object, and are not hereby expressly declared to be void.
Nothing herein contained shall affect any law in force in 1India and not hereby expressly repealed by which any contract is required to be made in writing2 or in the presence of witnesses, or any law relating to the registration of documents.
