Iowa Code § 633A.4801

Any governing instrument providing for a trust director or trust protector may also provide such trust director or trust protector with some, none, or all of the rights, powers, privileges, benefits, immunities, or authorities available to a trustee under the law of this state or under the governing instrument. Unless the governing instrument provides otherwise, a trust director or trust protector has no greater liability to any person than would a trustee holding or benefiting from the rights, powers, privileges, benefits, immunities, or authority provided or allowed by the governing instrument to such trust director or trust protector.
