My father-in-law had a POA in place naming all three of his children. The son, who has the caregiver and provided a home, had primary responsibility for the father. This included daily care, handling finances, doctors appt, etc. Father was still able to make his own decisions and those wishes were followed by the son. The father became ill and incapicitated and passed away within a few months. The other siblings, then began questioning finances and decisions made prior to his illness (while the father was still of sound mind). With all siblings listed as POA, how does this effect the assistance provided in financial matters by the primary caregiver.
