My parents have both been diagnosed with Dementia. My mom is so bad that she was not allowed to sign legal documents a month ago. I don't see how she can be a POA agent for my Dad at this point, but I don't know how to get that changed. My Dad is not far behind her in his mental decline. He holds POA for her. My brother lives in the same city and has tried to do whatever they will allow to help them. He is feeling overwhelmed and worried. He does not have the resources to hire an attorney and force them to assign POA or guardianship to him or someone other than eachother.
