Temporary or Special Probate Administrator Requirements in Missouri

At a glance

Requirements one by one

Missouri has two limited administration bridges

Under Mo. Rev. Stat. § 473.133, if the executor named in the will is a minor or absent from Missouri, letters may go to another person during that minority or absence. The appointee takes charge of the property and administers it under law and the court's direction. The section states no applicant, petition, notice, hearing, or emergency-showing formula.

The contested-will route is more specific. Under § 473.137, a person contesting the will must be found interested in its probate after a probate- division hearing. The court then grants administration letters to the named executor if that person has no beneficial estate interest beyond executor compensation. If the executor has an interest adverse to the contestant, the court may instead appoint a disinterested person or corporation.

The hearing statute gives no fixed appointment-notice period or recipient list and states no without-notice route. A separate no-notice possibility for a later business order does not eliminate the hearing required for the contest appointment itself.

Bond and neutrality depend on the route

The contest administrator must give bond. For the qualifying named executor, the court sets the amount; a disinterested alternate must give proper bond. The minority/absence statute does not contain its own bond sentence, so the general pre-duty rule in § 473.157 applies, subject to the exceptions cross- referenced in § 473.160. The bond secures faithful administration, accounting, payment, delivery, and compliance with law and court orders.

Ordinary personal-representative disqualifications in § 473.117 also remain relevant. They include minority, unsound mind, legal disability from a criminal conviction, habitual drunkenness, and specified out-of-state entities. The contest statute adds its own beneficial-interest and adverse-interest tests.

Ordinary administration law supplies most powers and limits

Section 473.133 directs the minority/absence appointee to take charge and administer according to law. Section 473.137 similarly directs the contest administrator to proceed with administration. If the decedent owned Missouri real estate, the contest court must direct that administrator to take charge of and manage it through the contest.

Under general § 473.263, an executor or administrator takes possession of personal property, while real-property possession requires a court order based on claim payment or preservation. Once ordered, the fiduciary collects rents, pays property taxes, keeps buildings in repair, and may insure them. Mo. Rev. Stat. § 473.270 requires collection of debts due the decedent and prosecution and defense of necessary actions.

Business continuation requires a separate court order under § 473.300 and a showing of advantage to the estate. That order may issue without advance notice, but the court must then require prompt notice and an opportunity to seek modification or reversal for previously unnotified interested persons.

Sections 473.133 and 473.137 create no separate remains, sale, mortgage, creditor-claim, debt-payment, expense-payment, or distribution rule. Those subjects remain governed by ordinary administration law, the will where applicable, and court orders; the limited appointment sections do not themselves expand or bar them.

Each appointment has an event-defined term

The minority/absence appointment lasts during the named executor's minority or absence. Section 473.137 instead directs the contest administrator to serve until the will contest terminates. At that point, the administrator must account to the executor or legal administrator when that successor qualifies.

Neither limited-appointment section supplies a separate removal or replacement process. The letters and court record must therefore be checked for any earlier court-ordered endpoint.

Inventory and settlements begin while the bridge is open

Under § 473.233, the personal representative must return an inventory and appraisement within 30 days after letters, unless the court grants more time. Under § 473.540, voucher-supported account statements are due annually on the letters anniversary and whenever the court directs, unless the court orders otherwise. The contest-end account to the qualified successor is an additional express handoff duty under § 473.137; § 473.133 states no separate turnover deadline.

Compensation follows § 473.153. It applies the will's compensation provision unless timely renounced, otherwise uses the statutory personal-representative schedule, and permits additional compensation needed to make the total reasonable and adequate. The limited-appointment sections state no separate fee, surcharge, bond-release, or liability formula.

What trips people up

• Missouri does not label these appointments “special administrator.” The current provisions use administrator during minority or absence and administrator pending contest; the function, not a generic label, places them in this survey.
• The named executor's position is conditional during a contest. Mandatory appointment under § 473.137 applies only when the executor has no beneficial interest beyond statutory compensation; an adverse interest opens the route to a disinterested appointee.
• The no-notice business order is not a no-notice appointment. The contest appointment itself follows the probate-division hearing required by § 473.137.

Common questions

Does a will contest always displace the named executor?

No. If the executor has no beneficial interest in the estate beyond executor compensation, § 473.137 says the court shall grant that person letters upon the required bond. An adverse interest permits a disinterested substitute.

May the contest administrator manage real estate?

Yes when the court finds the decedent owned Missouri real estate: the statute says the court shall direct the administrator to take charge of and manage it until the contest ends.

When is the first inventory due?

Within 30 days after letters are granted, unless the court allows longer.
