This is something I've been thinking about for a while. If my dad goes before my Mom, I want to set something up to protect my Mother. She's an extremely trusting person, and generally not good at understanding the things she signs. I don't want to take autonomy from her, but I'd like to set something up so any purchase over some set threshold would need to be verified by either my brother or myself. My Dad is probably going to leave her with a pretty decent nest egg... and I really worry about her, especially since both my brother and I live in another State.
