Free consent requires that a party's willingness to enter a contract is not caused by coercion, undue influence, fraud, misrepresentation, or mistake. Coercion involves threats to compel someone to act. Undue influence occurs when one party has power over the other due to status or relationships. Fraud involves intentional misstatements of fact to induce someone to act. Misrepresentation is a false statement of material fact that affects a party's decision. Mistakes involve erroneous beliefs about facts when contracting. Free consent ensures parties enter contracts voluntarily without improper external pressures affecting their decisions.
