"Fiduciary" is the term applied to anyone acting on behalf of another to manage assets that have been entrusted to the Fiduciary. The term includes an executor (who has been entrusted by the decedent to manage the assets of the decedent's estate for the estate's beneficiaries) and a trustee (who has been entrusted with the assets of the trust to manage them for the trust's beneficiaries). The same person can be both a "Fiduciary" and a beneficiary.
