Alzheimer's and divorce in your 80’s.

if a person has altzhimers and there wife that has it is trying to divorce and money was needed to pay for their health care and basic needs and he has orders from his doctors to not participate in any court can they hold him in contempt of court if he financially had to spend his money and now has no money left. and his daughter is named on his will as POA she hasn’t envoke it yet cause he still wants to manage his accounts not fully incompasitated yet can they hold her in contempt or give the POA to someone else to manage his funds. i don’t understand how a court can hold someone in contempt of court who has zero dollars? can he go to Jail for simply paying his medical bills.
