Miss. Code § 91-7-45
If the testator, by will, direct that his executor shall not be required to give bond, then none shall be required unless the court or the clerk, at the time of granting the letters or afterwards, shall have reason to require bond, in which event it shall be the duty of the court or clerk to require bond with sufficient sureties. If any creditor of such testator petition the court or the clerk in vacation, under oath, stating his claim and that he believes he is in danger of losing his demand, or some of it, by the bad management of said estate or by the personal insolvency of the executor, such executor, having had five days' notice of the petition, shall be required to give a bond with sureties, to be approved by the court or clerk in vacation, payable to said creditor in a sufficient sum to cover his legal demand, and conditioned to save him from all loss by reason of any act or omission of such executor. Instead of such bond, the executor may give bond as if he had not been relieved from it by the will. If the bond required in either case be not given, it shall be the duty of the court or clerk to remove the executor and grant letters of administration, with the will annexed, to some other person.
