Miss. Code § 91-7-309
Any person interested may, at any time within two years after final settlement, by bill or petition, open the account of any executor, administrator, or guardian and surcharge and falsify the same, and not after, saving to minors and persons of unsound mind the same time after the removal of their disabilities. Such bills or petitions may be filed without leave of the court or chancellor, and evidence shall be admissible in such cases to show the falsity of the account. Such bills and petitions shall not be governed by the rules applicable to bills of review in chancery, but in such cases it will be the duty of the court to correct any errors of law or fact occurring in the final settlement of the executor, administrator, or guardian.
