I was invited to speak at a Law Society of Ontario CLE seminar that took place on October 30, 2012. It featured many people who I consider some of the best practioners in this area. My paper analyzed whether Justice Cullity, in Banton v. Banton, expanded the test on insane delusions. At the actual presentation, Jordan Atin, the Chair of the program, asked Ian Hull and me to address a potpourri of issues. My topics included capacity, undue influence, managing client expectations, and evidence in the context of estate disputes. Ian Hull spoke on strategy in estate litigation among other topics. At the conclusion of the seminar I received a number of requests to provide my notes or something more formal to those who enjoyed the presentation. They felt the time was short and wanted specifics of some of the source material I referred to for use in their practice. This blog is, in part, a response to those requests and provides a review and sources for my comments on capacity and undue influence.
