My father was recently told that his cancer is terminal. We are going through legalzoom.com to prepare a Living Trust, but we weren't sure if a Will can accomplish the same goals we have in mind for the Trust. Mainly we have a sibling who will not be receiving as much, but he will be receiving something. In the Trust we have a 40-40-20 split of estate assets with no specific gifts given to him; if we do a Will, he will be left $500 to cover the law. This is necessary in order to protect my parents' hard-earned money.
Which is the better route to go in this case? How aggressively is he able to contest the terms of either, even if there is a clause that states whoever contests will have their gifts revoked and those gifts will be reverted to equal shares? Thank you in advance.
