I am the executor of both of my parents' estate, which involves a couple of properties. My father recently died and I have been working tirelessly with the estate attorney to settle the estate. My sister and I have been doing everything to support my elderly mother, while 3 of my other siblings have broken off into a faction and have made totally unfounded accusations, such as "hidden codicils". They refuse to communicate directly, other than by poison emails, and continue to fight me every step of the way.
I have kept my attorney in the loop, and he has assured me that I'm doing everything by the book and not to worry. I have reason to believe, however, that the sibling faction will try to coerce my mother to draw up a new will. While she has assured me that she won't sign anything, she is 92 years old and is quite impressionable.
My question is this: Is there anything I can do legally to preempt this situation? I do have power of attorney.
