Missouri Revised Statutes Title XXXI. Trusts and Estates of Decedents and Persons Under Disability § 473.137. Administrator pending contest, appointed when--duties

1. If the validity of a will is contested by any person who, after a hearing in the probate division, is found to be interested in the probate of the will, the court shall grant letters of administration to the executor named in the will, if he has no beneficial interest in the estate save the compensation allowed by law to executors, upon giving bond in such amount as the court may require.

2. If, after such hearing, it appears that the executor named in the will has an interest adverse to any such contestant of the will, the court may, in its discretion, grant letters of administration to some disinterested person or corporation, who shall give proper bond.

3. An administrator appointed pursuant to this section shall proceed with the administration of the estate until termination of the will contest, at which time he shall account to the executor or legal administrator when qualified, and, if it shall appear to the court that the decedent died possessed of real estate in the state, the court shall direct him to take charge of and manage such real estate until the termination of such will contest.
