Me, my brother & mother all agreed to hire a so-called "friend" to help mom recover from the hospital, go to doctor appointments, help physically get around and meals. She has extended her hours, brought in her daughter to help also. Mom is so doped up on pain meds (most of the time), they spend hours shopping and mom pays for whatever they want. They treat her house as if it's their house. We have financial & medical POA but mom is aware enough to pay them and angry if we threaten to handle her business. They are now helping her pay bills and have isolated her from friends and most of the family. It seems we have to make an appointment almost to visit and then she sleeps while we're there. Not sure if we have the power to get rid of these people? Mom will be very angry and will not forgive us because she's sees nothing wrong with the situation. We don't know where to go with this?
Lastly, you could report the so-called caregiver to Adult Protective Services. Isolating a vulnerable elderly person from their friends and family is a red flag, and APS might step in to help you.
Have you and your brother tried speaking directly to the culprit caregiver? What was her response?
Also, crucially, what are the terms of your POA? Is it designed to "spring" in the event of your mother's incapacity?
