A fiduciary is a person or organization that acts on behalf of another person or persons, putting their clients’ interests ahead of their own, with a duty to preserve good faith and trust. Being a fiduciary thus requires being bound both legally and ethically to act in the other’s best interests.
A fiduciary may be responsible for the general well-being of another (e.g. a child’s legal guardian), but often the task involves finances; managing the assets of another person, or a group of people, for example. Money managers, financial advisors, bankers, insurance agents, accountants, executors, board members, and corporate officers all have fiduciary responsibility.
