Mississippi Code
Article 4 - Creation, validity, modification, and termination of trust
§ 91-8-410. Modification or termination of trust; proceedings for approval or disapproval

In addition to the methods of termination prescribed by Sections 91-8-411 through 91-8-414, a trust terminates to the extent the trust is revoked or expires pursuant to its terms, no purpose of the trust remains to be achieved, or the purposes of the trust have become unlawful or impossible to achieve.
A proceeding to approve or disapprove a proposed modification or termination under Sections 91-8-411 through 91-8-416, or trust combination or division under Section 91-8-417, may be commenced by a trustee or beneficiary. The settlor of a charitable trust may maintain a proceeding to modify the trust under Section 91-8-413.
Nothing in this section or this chapter is intended to create or imply a duty for a trustee to make or seek approval of a modification, termination, combination or division, and a trustee is not liable for not making or seeking approval of a modification, termination, combination or division.
