Bank trust fees include charges for trust administration, asset management, and sometimes legal services and record keeping, according to Barron's. Trust department fees at private banks are higher than those at asset management companies. Banks levy trust fees as a percentage of trust assets instead of a fixed dollar amount.
Trust fees are negotiable, explains Barron's. The amount of the administration fee depends on the size of the trust and the complexity of the assets in the trust. The larger the trust, the lower the percentage charged to administer the trust. On the other hand, banks charge higher percentage fees if the trust holds difficult assets to manage such as private equity investments or if it covers several generations of beneficiaries.
