Mississippi Code Title 91. Trusts and Estates § 91-7-99

If there be more than one executor, administrator, or temporary administrator, they shall all join in returning the inventories. If one or more refuse to do so, the others may return them, and the power and authority of the person so refusing shall thereafter cease. Those who return the inventory shall proceed in the administration, unless the delinquent, within sixty days, assign a reasonable excuse which the court may deem satisfactory.
