I have a sister who is challenging my POA that I have for my elder parents. She has tried twice to get into my parents bank account without even discussing it with me first. My parents are both approaching dementia and hardly remember what people say or have said from day to day. My concern is what she will try to do next.
Can she go to the court to seek guardianship over my parents if she gets a doctor's note stating they are incompetent, despite me being the one with the POA? Could she challenge my POA? What is the process and what can I do to stop this from potentially happening?
