Evertime my older sister comes to visit from out of state, she tries to get my mother to change the decisions my mother has made regarding her future. It includes the will and how my mother should be taken care of when she cannot live independently without help. I am the executor of her will, have durable power of attorney, healthcare proxy and joint ownership on her checking account mostly because I live the closest. My mother is 82 and competent, but somewhat vulnerable to dealing with my controlling sister. With the will, my sister wants to exclude our step sister as an heir. My sister is also trying to take control of how my mother will be taken care of when she will not be able to live indepenently without help. All this has been discussed and decided between my mother and I. Yet, my mother calls to discuss with me my sister's suggestions. My sister is the type that will help, bu only if it also benefits her. I am ready to just turn it all over to my sister if my mother doesn't stop allowing my sister to interfer. Has anyone else had similiar problems and how they handled it?
