Do I do. My father died 8 years ago and I just find all this hidden documentation . at moms house? I asked the attorney and my sister. They will not answer. The only answer that was given was that my sister took the trust agrrement. Isn't the attorney and my sister responsible for telling me( beneficiary and co trustee w/ stamped durable POA in Nassau County) about what my Dad let my mother and me. Why did they hide the POA from me I helped my Dad at hospital for 8 months. My mom does not speak English and I am trying to piece together the events. What should I do first with an attorney search the unprobated will or trust documents is it too late ? I just found these hidden docs a few months ago?
