My sister claims she is "executor" of mother's estate, who recently passed . She is now claiming there is no will. I asked for a fewitems of mother's & she went on a "power trip", telling me to leave and saying she never wanted to see me again. There are 5 of us & my mother recently sold her house. She had a stroke and as P.O.A. my sister let her get ripped off. I said the sale contract should have been voided because of my mother's medical condition. I also found out that my mother also owned a "cottage by the ocean", which I knew nothing of. I know nothing of her assets Worst of all mother SHOULD have been autopsied due to circumstances of her dearh, but I can't even find out. My sister said she was going to cremate. I am extremely angry over this, plus her attitude. What do I do?
