Wording in a will or trust which allows a named person to decide where your property and money should go after your death (instead of you making that decision ahead of time) is called “precatory” language.  An example is the recent Florida case of Cody v. Cody, where Earler Martin’s will left his home, and the rest of his estate, to one of his three stepsons, “to divide between [himself and his brothers], as he sees fit and proper.”  Earler’s wish was probably that the inheriting stepson, Buford, divide up the home and other property equally between himself and his brothers.  However, the words he chose to express that desire defeated that intent.
