I am 85 years of age; my wife (84) is in hospice care in our home and unresponsive (Alz). We both have DNR's. Do I need a POA for her final affairs? We have a daughter. Should I obtain a POA for her in the event that I become afflicted and unresponsive? If so, can you give me an idea as to the expense involved? I don't have an attorney.
