My three siblings and I live on the east coast and do not trust the sibling living near our elderly father. Should we insist that a neutral lawyer with no personal ties update my father's living trust? We are concerned that our father is being taken advantage of, since he is 92 years old and will go along with anything to avoid conflict. The lawyer is discussing details of the trust with the close sibling (her friend) but refuses to discuss any details with the rest of the family living back east. Should we be concerned and if so, what recourse do we have?
