Mississippi Code
Article 10 - Liability of Trustees and Rights of Persons Dealing with Trustee
§ 91-8-1012. Protection of person dealing with trustee

A person other than a beneficiary who in good faith assists a trustee, or who in good faith and for value deals with a trustee, without actual knowledge that the trustee is exceeding or improperly exercising the trustee's powers is protected from liability as if the trustee properly exercised the power.
A person other than a beneficiary who in good faith assists a trustee or deals with a trustee is not required to inquire into the extent of the trustee's powers or the propriety of their exercise.
A person who in good faith delivers assets to a trustee need not ensure their proper application.
A person other than a beneficiary who in good faith assists a former trustee, or who in good faith and for value deals with a former trustee, without actual knowledge that the trusteeship has terminated, is protected from liability as if the former trustee were still a trustee.
Comparable protective provisions of other laws relating to commercial transactions or transfer of securities by fiduciaries prevail over the protection provided by this section.
