Miss. Code § 91-7-53
Whenever it shall be necessary for the care and preservation of the estate of a decedent before the grant of letters testamentary, or of administration, to the person entitled thereto, the chancery court or chancellor in vacation, or the clerk of such court, on the petition of any creditor or other interested person, shall appoint a suitable person to be known as "temporary administrator." The person named as executor or the person apparently entitled to letters of administration may be appointed temporary administrator, unless the court shall find that the circumstances require the appointment of a different person.
Whenever an appeal shall be taken from the grant of letters testamentary, or of administration, or whenever a last will and testament shall be contested, the chancery court or chancellor in vacation, on petition of any interested person, may appoint a temporary administrator if it shall appear necessary for the protection of the rights of the parties, and may make such appointment on such terms and impose such conditions as may seem proper.
The powers of such temporary administrator may be special or general, as the court may find proper, and he may be authorized to take charge of, preserve, and administer the estate until the appeal or contest shall be determined. Letters may be issued to him in ordinary form, except that he shall be therein designated as temporary administrator, and any terms or conditions imposed shall be stated therein; and the letters shall state that he is to act only until another appointment shall be made, either temporary or permanent.
