Say that you want to set up a trust for a grandchild so that they can pay for their education. It's a wise use of your money, and creating that trust can be part of your estate planning.
Your parent's will arrives, and you just don't like the terms. Maybe you thought that you'd get a specific asset or maybe you thought more money would go your way. You have been looking forward to it, and now you're disappointed. Can you challenge the will?
