Ark. Code § 28-69-207
Any state bank, national bank, or trust company qualified to act as a fiduciary in this state, is hereby specifically authorized to utilize its respective affiliates to provide services for any trust or estate for which the financial institution or trust company acts as a trustee or other fiduciary, provided the financial institution believes, in the exercise of the standard of care described in § 28-71-105, that the services are reasonably necessary and that its affiliate can render such services, including, but not limited to, securities brokerage services, computer services, and banking services, to the trust or estate as competently as similar services rendered by nonaffiliates and for compensation equal to or less than that charged by nonaffiliates. Provided the foregoing requirements are met, an affiliate may be utilized by the financial institution or trust company without the approval or consent of any person or specific authorization in the trust instrument, unless such a power is expressly withheld in the trust instrument.
