My MIL's husband has decided to drop her off at our house, permanately. She has progressive supranuclear palsy. They have split their time between traveling around the country and staying at our home for long stretches for around 3 years now. Usually they have only one hospital stay per trip. Either he has a heart attack or she goes unconcious from lack of food or water because they forget to eat. She has become more verbally abusive to him. Also, this last trip she had to be in the hospital every three days. When she came out she was verbally abusive to everyone she saw. He found it inconvenient since he is almost 80 years old and is trying to reconnect with family before they die. we understand that it is usually a UTI which is why He takes her to the doctor when she comes back and the doctor diagnoses it and treats it. They are destitute so we are trying to get them on medicaid. They have only a couple of cars and the RV that they live in. We have put down that she lives with us so she can get the state medicaid. However i am wondering, will that cause them to look at OUR family as members of their household. Also he is leaving in a few days and probably won't be back. We are trying to get him to sign a medical power of attorney so we can at least take her to the hospital and ask questions. Something we haven't been able to do up to this point. Will that be enough? Is there something else we should do? Or have we just stepped into a hornets nest?
