My mother in-law has been diagnosed with Alzheimers in the last 2 years and currently my partner and his sister have joint power of attorney for property and finances, which was gained over a year ago now to support her with bills etc whilst living at home. This last year has seen rapid deterioration to the point where very little is remembered and I would not feel she is mentally 'sound' to go through forms for the health and well being paperwork for power of attorney, but someone needs to be able to make decisions on her behalf now. Wishing both had been done at the same point before things got this bad, but this is where we are at. Does anyone know what the alternative is when this point is reached?
