My father died 2 months ago and my sister was power of attorney and now executor of his will/estate. I know I am an heir, because she had to confirm my address for her lawyer handling the estate. She refuses to let me have the lawyer's name and phone number. And she won't let me have a copy of his will. Since she also refused to keep me informed of his health and if he needed money for the nursing home, I believe she is hiding something. Do I have the right as an heir to know the lawyer's name and phone number? And if she still refuses, can I sue her? And how?
