undue influence

In contract law , undue influence is a defense used to argue against the formation of a binding contract . It occurs when one party exerts excessive persuasion on another, undermining their free will and leading to a contract that benefits only the influencer. To prove undue influence, it must be shown that the influenced party had vulnerabilities making them susceptible to persuasion, and that the influencer was in a special relationship of trust , dependency, or authority over the victim. If undue influence is established, the contract, will , or legal instrument in question can be rendered unenforceable and voidable by the influenced party.
