Mississippi Code
Article 8 - Duties and Powers of Trustee
§ 91-8-808. Powers to direct

While a trust is revocable, the trustee may follow a direction of the settlor that is contrary to the terms of the trust or contrary to the normal practice of the trustee in regard to the action requested.
If the terms of a trust confer upon a person other than the settlor of a revocable trust power to direct certain actions of the trustee, the trustee shall act in accordance with an exercise of the power.
The terms of a trust may confer upon a trustee or other person a power to direct the modification or termination of the trust.
If a person holds a power to direct pursuant to Article 12 of this chapter, that person is a trust advisor, trust protector, or both. The power holder is subject to all the provisions of Article 12, including any duties prescribed by Article 12 and any provisions that make the power holder a fiduciary. Any trustee or other person that under Article 12 is relieved of any duty or any liability, or is otherwise protected under Article 12, shall be so relieved and otherwise protected.
