A private fiduciary is a non-family member who is certified by the Arizona Supreme Court Fiduciary Certification Program to serve clients professionally, for a fee. A private fiduciary may be appointed by the court to serve as guardian, conservator or personal representative of an estate if the fiduciary is not a beneficiary of that estate. Private fiduciaries may also serve, by agreement, as trustees, representative payees, or as agents under powers of attorney.
