Undue influence remains one of the most litigated — and most misunderstood — claims in trust and estate disputes. But what counts as coercion or manipulation can vary widely by jurisdiction. This session brings together two litigators from different legal cultures to compare how undue influence is pleaded, proved, and rebutted. They will facilitate a discussion about evidentiary burdens, the role of capacity assessments, presumptions of dominance, and the credibility challenges common to these emotionally fraught cases. They will bring examples from high-profile Florida appellate reversals and the Royal Court of Jersey court findings, and will be inviting their colleagues to share their own perspectives and experiences.
