I'm trying to find out if it is possible for people not yet existent to be appointed as beneficiaries of a Discretionary Trust.... ie: Grandchildren that are yet to be born. Can this be done? ie: Jack and Jill writing their wills. One child, Melissa. Melissa has 0 children. Jack and Jill want to leave Shares to Melissa's children, when/if she has them. Thanks for your help guys!
