CA - My father had a simple AB Trust prepared before he passed away leaving me as the executor of the estate. My mother who is alive refuses to give me a copy of the trust as she does not trust anyone. This is complicated by the fact that she is now in the early stages of dementia. I know which law firm has a copy of the trust. Should I simply call the law firm and request a copy of the trust document or does she have to be declared incompetent before this can be released from the law firm? Also do I have any liability for her actions? Any suggestions for the best course of action or various options would be greatly appreciated.
