A presumption of undue influence is a legal concept, often in will or trust disputes, where a court assumes improper pressure occurred if a fiduciary/confidential relationship existed, the influencer had the opportunity to influence, and the influencer benefited from the transaction. This shifts the burden of proof, requiring the influencer to show they didn't exert undue influence, rather than the challenger proving they did. It's a way to "level the playing field" in cases where proving direct coercion (threats, fraud) is difficult, as undue influence often happens privately.
