Wow, I had no idea so many of you would leave such (mostly) wonderful and helpful comments! Thank you! I won't be able to reply to each one, but I'll add some clarifying details. My parents have living wills in place, but they only name each other as POA. We're working on getting my brother listed as the new POA for both medical and financial. My mom has been ill for years, and my dad has spent the last 8 years being her full time caregiver, and 4 years ago, my other brother moved in.
