Fiduciary

Fiduciary, in law, a person who occupies a position of such power and confidence with regard to the property of another that the law requires him to act solely in the interest of the person whom he represents. Examples of fiduciaries are agents, executors and administrators, trustees, guardians, and officers of corporations. They may be contrasted with persons in an ordinary business relationship, in which each party is free to seek purely personal benefits from his transactions with the other.
