My dad is in a memory care unit, mom is in assisted living. Both have Alzheimer's needing different levels of care. Both are/were happy, comfortable where they are although they would like to be together. Six months ago they were living in their own house with limited home care services because dad would not allow additional help. Mom was placed in Assisted living due to a fall, but no major injury. Dad couldn't care for her. Three months later, Dad was placed in a Memory care unit due to wandering and needing hygiene assistance. I have 5 siblings. All were on board for mom's placement. Unfortunately, when dad needed more care, there were no facilities available that could care for both of them. So we found a complex that has them across a driveway from each other and mom can visit dad daily, if she wants. The problem is one sibling(#3) is going rogue and taking them out of their facilities frequently (3 times a week) for hours on end. They have not asked to be taken out and are tired out from the activity. They were never that active before. #3 has been telling them both that once dad's foot clears up (it is infected, but he refuses medication), they can be moved in together in the assisted living facility. This week #3 took dad to tour another facility. Now she wants me to fill out a financial form for that facility. She thinks that dad is healthier now and will pass an evaluation for an assisted living facility rather than a memory care unit. She doesn't understand that the Alzheimer's diagnosis will not go away. I am Heath care Proxy and POA. My brother (#5) is also POA and second on the Health care Proxy. He is getting sucked into her lies. She asked him to get the tenant agreement from their current location but didn't tell him it was to fill out an application. I have been paying their bills for the last 4 years. He has had nothing to do with it and wants nothing to do with the financial piece. #3 has secretly taken dad to the bank twice to withdraw money. It was a small amount, but I do not trust her. I moved the money. Two other sisters #2 and #6 have been doing an outstanding job caring for our parents for the last two years getting them to dr appts and grocery store, doing their laundry, cleaning. They are the closest in physical proximity to the parents. I live 5 hours away, and visit monthly. #3 has cut off almost all communication with the rest of the family and is doing whatever she wants with our parents. Can I do anything to stop #3 from tearing our family apart and upsetting my parents by giving them false hope and using them as pawns? Can I prevent her from taking them to the doctor for an evaluation?
