Fiduciary

Relating to or involving trust (such as the trust between a customer and a professional).

Fiduciary relationships often concern money, but the word fiduciary does not, in and of itself, suggest financial matters. Rather, fiduciary applies to any situation in which one person justifiably places confidence and trust in someone else and seeks that person's help or advice in some matter. The attorney-client relationship is a fiduciary one, for example, because the client trusts the attorney to act in the best interest of the client at all times. Fiduciary can also be used as a noun for the person who acts in a fiduciary capacity, and fiduciarily or fiducially can be called upon if you are in need of an adverb. The words are all faithful to their origin: Latin fidere,which means "to trust."
