Did you know?

Fiduciary relationships are often of the financial variety, but the word fiduciary does not, in and of itself, suggest pecuniary ("money-related") 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 referring to 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 fīdere, which means "to trust."
