Black's Law Dictionary
(Also called "instrumental trusts.") Those which demand no further exercise of reason or understanding than every intelligent agent must necessarily employ; as to convey an estate. They are a species of special trusts, distinguished from discretionary trusts, which necessarily require much exercise of the understanding.
