Undue influence is not mere persuasion or advice. It requires coercive elements that override the testator’s free will and judgment.
Courts look for a combination of susceptibility, opportunity, and improper pressure that causes the vulnerable person to act contrary to their true wishes.
Undue Influence:
- is a legal concept used to challenge the validity of a document or agreement when a dominant party manipulates a vulnerable individual
- occurs when one party exerts excessive pressure, manipulation, or control over another, compromising free will in a legal action such as a will, contract, or settlement
- behavior typically involves coercive tactics, fiduciary abuse, or exploitation of trust
This article explains how to (prove or) disprove undue influence in court, outlining the legal standards, types of evidence that matter, and practical strategies for presenting a persuasive case in the American legal system. It covers how judges evaluate influence, what distinguishes undue influence from legitimate persuasion, and how to structure a compelling evidentiary record for trial or settlement disputes.
