My wife has signed up to be attorney for her elderly father, he is currently in hospital and likely to be deemed to be lacking mental capacity any time soon. At that point my wife will be legally obliged to invoke LPA ... however where does that leave her fathers still competent wife (who is his carer) in all of this?? We strongly suspect that he would have wished his wife to be his attorney until such time she became incapacitated,, and then attorney responsibility would fall to my wife. We believe that my wifes father is now too incapacitated to alter his wishes.
