A voidable contract arises when one party is subjected to coercion, rendering their consent involuntary. Coercion involves the use of force or threats to compel someone to enter into an agreement against their will. In such cases, the affected party has the option to either affirm the contract or void it. The key element is the presence of undue influence that deprives the coerced party of free and voluntary choice. Voidability provides a legal remedy to the victimized party, allowing them to escape the contract's obligations. Courts may intervene to protect individuals from agreements tainted by coercion, ensuring fairness and upholding the principle of genuine consent.
