There was a case of a woman with dementia, an only child, living all by herself, her neighbors do what they can to support her and be there for her. Even though there was a Homecare agency involved in her care, their part was minimal. Her neighbors went as far as taking her lawyer and a social worker to court, for mismanagement and were fighting to bar her only relative, (a cousin who they claimed cashed her checks and used the money to buy himself a house) out of her life. I have also heard cases of caregivers stealing from their vulnerable clients, but fiduciary stealing from a client, came as a surprise. According to Wikipedia, a fiduciary is a person who holds a legal or ethical relationship of trust with one or more parties, fiduciary duties in a financial sense exist to ensure those who manage other People’s money act in their beneficiaries’ interest, rather than serving their own.
