am calling about my first husband, JA. He told me in December he was divorcing A and changing his will. He will soon be going in palliative care. His wife is telling the hospital in N.F that she is the POA and has said no one is allowed to visit. He told the nurse she was not his POA on Monday when I was visiting him. Do not call his phone because she is pretending to be him with text messages. Is this true about divorcing and changing the will?
