Sister positioned herself in such a way as to have all access to mother's estate.Mother(was dying from cancer), sister made sure everything went to herself - Help! Sister is an alcoholic and a VERY manipulative person. Greedy, always. Dad passed away, sister immediately got her name on all Mom's accounts. Lived off of parents one way or another all her life, never having to pay a mortgage-lived in Mom & Dads houses mortgage free. Need advice on how to contest will or her being an Executor!
