Section 12 in The Indian Contract Act, 1872

Title: What is a sound mind for the purposes of contracting.

Description: A person is said to be of sound mind for the purpose of making a contract, if, at the time when he makes it, he is capable of understanding it and of forming a rational judgment as to its effect upon his interests. A person who is usually of unsound mind, but occasionally of sound mind, may make a contract when he is of sound mind. A person who is usually of sound mind, but occasionally of unsound mind, may not make a contract when he is of unsound mind. Illustrations (a) A patient in a lunatic asylum, who is at intervals of sound mind, may contract during those intervals. (b) A sane man, who is delirious from fever or who is so drunk that he cannot understand the terms of a contract, or form a rational judgment as to its effect on his interests, cannot contract whilst such delirium or drunkenness lasts.

Title: "Consent" defined.

Description: Two or more persons are said to consent when they agree upon the same thing in the same sense.

Title: "Free consent" defined

Description: Consent is said to be free when it is not caused by— (1) coercion, as defined in section 15, or (2) undue influence, as defined in section 16, or (3) fraud, as defined in section 17, or (4) misrepresentation, as defined in section 18, or (5) mistake, subject to the provisions of sections 20, 21 and 22. Consent is said to be so caused when it would not have been given but for the existence of such coercion, undue influence, fraud, misrepresentation or mistake.

Title: "Coercion" defined.

Description: "Coercion" is the committing, or threatening to commit, any act forbidden by the Indian Penal Code (45 of 1860) or the unlawful detaining, or threatening to detain, any property, to the prejudice of any person whatever, with the intention of causing any person to enter into an agreement. Explanation.—It is immaterial whether the Indian Penal Code (45 of 1860) is or is not in force in the place where the coercion is employed. Illustration A, on board an English ship on the high seas, causes B to enter into an agreement by an act amounting to criminal intimidation under the Indian Penal Code. (45 of 1860). A afterwards sues B for breach of contract at Calcutta. A has employed coercion, although his act is not an offence by the law of England, and although section 506 of the Indian Penal Code (45 of 1860) was not in force at the time when or place where the act was done.

Title: "Undue influence" defined.

Description: 1[16. Undue influence defined.-- (1) A contract is said to be induced by "undue influence" where the relations subsisting between the parties are such that one of the parties is in a position to dominate the will of the other and uses that position to obtain an unfair advantage over the other. (2) In particular and without prejudice to the generality of the foregoing principle, a person is deemed to be in a position to dominate the will of another— (a) where he holds a real or apparent authority over the other, or where he stands in a fiduciary relation to the other; or (b) where he makes a contract with a person whose mental capacity is temporarily or permanently affected by reason of age, illness, or mental or bodily distress. (3) Where a person who is in a position to dominate the will of another, enters into a contract with him, and the transaction appears, on the face of it or on the evidence adduced, to be unconscionable, the burden of proving that such contract was not induced by undue influence shall lie upon the person in a position to dominate the will of the other. Nothing in this sub-section shall affect the provisions of section 111 of the Indian Evidence Act, 1872 (1 of 1872). Illustrations (a) A having advanced money to his son, B, during his minority, upon Bs coming of age obtains, by misuse of parental influence, a bond from B for a greater amount than the sum due in respect of the advance. A employs undue influence. (b) A, a man enfeebled by disease or age, is induced, by Bs influence over him as his medical attendant, to agree to pay B an unreasonable sum for his professional services, B employs undue influence. (c) A, being in debt to B, the money-lender of his village, contracts a fresh loan on terms which appear to be unconscionable. It lies on B to prove that the contract was not induced by undue influence. (d) A applies to a banker for a loan at a time when there is stringency in the money market. The banker declines to make the loan except at an unusually high rate of interest. A accepts the loan on these terms. This is a transaction in the ordinary course of business, and the contract is not induced by undue influence.] 1. Subs. by Act 6 of 1899, s. 2, for the original s. 16.
