My Mom has always been my best friend. I took care of Mom in her home for 6 1/2 years. Then she was put in a nursing home. She's been there over 4 years and is now in the end stages of vascular dementia. My father died of Alzheimer's Disease 13 years ago, and one of my younger brothers has early-onset Alzheimer's and is in another nursing home. I visit him and my Mom on Sundays. My youngest brother (I'll refer to him as L.S.), an accountant, was named POA by my father, long before any of this happened. Not long ago, my youngest brother's wife, K.S., told me that she believes L.S. is now showing early signs of dementia. Unknown to me, K.S. has been doing the duties of POA for some time now, because L.S. doesn't seem to be able to do the paperwork involved any more. I didn't realize this was going on, but did know that she seemed to be helping him to some degree. Yesterday, while visiting Mom, a nurse on her unit told me that Mom had been attacked by another patient earlier in the week and was badly bruised and shaken up. She said the other patient is a "Psych" patient, on a floor with all these weak, confused dementia patients. I asked what was being done about this. She said that she and the other staff had been instructed "not to talk to the family about this." She said she was concerned, though, that he psych patient was still there and hadn't been moved to another unit. So I called the nursing home this morning to talk to an administrator, and was told that they were "working on this" and that it is a "major investigation." She said they could give me no details because I am not the POA, but that a call had been made to L.S. and K.S. She said it is legally my brother's responsibility to tell me what is going on. Since my brother is apparently somewhat incapacitated, and my sister-in-law has been illegally acting in his place - I want to get guardianship over my mother. I've been looking into this process online today, and it looks like I'd have to go before a judge, along with L.S. and K.S., and somehow prove that L.S. is incapable of continuing to be the POA. I also saw that it might be simpler to be made "secondary POA" for my mother. Since my mother obviously cannot "sign off" on this, how would this be done?
