Mississippi Code
Article 7 - Office of Trustee
§ 91-8-701. Accepting or declining trusteeship

Except as otherwise provided in subsection (c), a person designated as trustee accepts the trusteeship:
A person designated as trustee who has not yet accepted the trusteeship may reject the trusteeship. A designated trustee who does not accept the trusteeship within a reasonable time after knowing of the designation is deemed to have rejected the trusteeship.
A person designated as trustee, without accepting the trusteeship, may:
Act to preserve the trust property if, within a reasonable time after acting, the person sends a rejection of the trusteeship to the settlor or, if the settlor is dead or lacks capacity, to a qualified beneficiary; and
Inspect or investigate trust property to determine potential liability under environmental or other law or for any other purpose.
