Miss. Code Ann. § 81-5-35

No state or national bank domiciled in this state and duly authorized by law to act in a fiduciary capacity shall be required to make or file any bond or other security for the faithful performance of its duty when acting as executor, administrator, guardian, conservator, trustee, or in any other fiduciary capacity, unless the instrument creating any such trust or the court having jurisdiction thereof shall specifically direct that such bond or other security shall be given for the performance of such trust and shall fix the amount thereof. The chancery court or chancellor in vacation, having jurisdiction over any such estate or trust existing at the time of the enactment of this statute may, in its discretion, cancel any such bond or release any such security and discharge the surety or sureties thereon. However, the retroactive effect of this section shall not apply to the release of any such bond or security or surety on any estate, guardianship, or trust on which a bond or security or surety was required as a result of the failure of a probated will to waive bond, security, or surety.
