For a contract to be valid, the consent of the parties must be genuine. The principle of consensus-ad-idem is followed. Mere consent is not enough for a contract to be enforceable; the consent given must be free and voluntary. The definition of free consent provided under the Indian Contracts Act is consent that is free from coercion, undue influence, fraud, misrepresentation or mistake. 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. Clearly, free consent means the absence of any kind of coercion, undue influence, fraud, misrepresentation, or mistake. When the consent that is given is affected by these elements, it calls into question whether the consent given was free and voluntary. The objective of this principle is to ensure that the judgment of the parties while entering into the contract wasn’t clouded. Therefore, consent given under coercion, undue influence, fraud, misrepresentation or mistake has the potential to invalidate the contract. Free consent is absolutely essential to make an agreement a valid contract. The importance of free consent cannot be stressed enough. The consent of the parties to the contract must be free and voluntary. Consent to the contract has to be given without any kind of pressure or delusions.
