Excessive persuasion, pressure, or manipulation that overcomes the free will of a testator or settlor, causing them to execute a will or trust contrary to their true wishes. Undue influence requires showing the influencer had opportunity, motive, and actually exerted pressure that substituted their will for the testator's independent judgment.
Undue influence is when someone pressures or manipulates you into making a will that reflects their wishes, not yours. It's more than just persuasion—it's crossing the line into coercion that overpowers your own free choice.

💡 Did you know?
Courts are particularly suspicious of undue influence when a caregiver, attorney, or person in a position of trust receives large unexpected gifts or inheritance. Many jurisdictions have laws creating a presumption of undue influence in these situations, shifting the burden to the recipient to prove the gift was legitimate.
