Letters of Administration Appointment Requirements in Missouri

At a glance

Requirements one by one

One proceeding, probate division, and venue

Mo. Rev. Stat. § 472.020 places letters testamentary and of administration in the probate division of the circuit court. Mo. Rev. Stat. § 473.013 treats the administration from application through final distribution and discharge as one in-rem proceeding. The application states whether supervised or independent administration is requested.

Mo. Rev. Stat. § 473.010 starts venue in the decedent's Missouri domicile county. A nondomiciliary estate generally uses a county containing property, but when most Missouri property is real estate, the realty county controls. If the decedent had neither Missouri domicile nor property, venue may lie where letters are needed to protect or secure a legal right. The first-filed application controls a competing-venue question.

Twenty-day filing route and appointment priority

Mo. Rev. Stat. § 473.110 supplies the priority ladder. A will nominee receives letters unless the nominee fails or cannot serve. For intestacy, the spouse ranks first. Next comes one or more distributees whom the court believes will best manage and preserve the estate. If no preferred person is competent and suitable, or a person directed to apply does not do so, the court may choose another person.

Mo. Rev. Stat. § 473.020 gives that priority system a twenty-day window after death. If no entitled person applies within it, any interested person may file the special petition. Within fifteen days, the court holds a noticed hearing and may direct the entitled person to apply and qualify, appoint another suitable person on default, refuse letters, or dismiss the petition.

Application contents and post-letters notice

Mo. Rev. Stat. § 473.017 requires the ordinary application to give the decedent's identity, age, domicile, residence, and death facts; spouse, heirs, devisees, legatees, minors, disability information, and conservators; property values; additional nondomiciliary property facts; will and executor facts; the proposed intestate representative's relationship and priority facts; the attorney; the fiduciary undertaking; and the supervised-or-independent choice. The post-twenty-day § 473.020 petition instead uses its shorter three-item list.

After letters issue, Mo. Rev. Stat. § 473.033 makes the clerk publish notice once each week for four consecutive weeks and mail each listed heir and devisee. An heir or devisee may waive that mailed notice by a writing filed with the court.

Qualification, nominations, bond, and letters

Section 473.110 lets an adult priority holder with sufficient capacity nominate a qualified person. A priority holder may renounce the right to nominate or be appointed by an appropriate writing filed with the court. When several people share priority, the nonrenouncing people must concur in the nomination or application.

Mo. Rev. Stat. § 473.117 bars the listed court officials except for close-family estates, people under eighteen or of unsound mind, people legally disabled by a crime conviction, habitual drunkards, listed foreign entities, and a personal representative's successor merely by reason of that succession. A qualified nonresident may serve, but before letters must designate a Missouri resident or authorized Missouri trust corporation for service and notice.

Mo. Rev. Stat. § 473.023 allows the probate division or clerk to grant letters, subject to court modification or revocation. Under Mo. Rev. Stat. § 473.157, the representative ordinarily files an approved bond with sufficient security before beginning duties. Mo. Rev. Stat. § 473.160 permits the will's no-bond request, the qualifying-corporation exception, and a court good-cause finding; depositing assets reduces bond only in proportion to deposited value.

What trips people up

• The twenty days are a priority window, not the final deadline. After that period, an interested person can force the noticed hearing route, but the court still starts with the statutory entitlement ladder.
• Distributee priority is not automatically the largest share. The court chooses one or more distributees it believes will best manage and preserve the estate.
• A deposit does not erase bond. Section 473.160(2) reduces the bond in proportion to the deposited assets and restricts later withdrawal.
• The court may refuse full letters. Mo. Rev. Stat. § 473.090 covers estates consumed by exempt property and family allowances and a separate creditor route when personal estate does not exceed $15,000.

Common questions

Can equal-priority family members nominate one person?

Yes, but the nonrenouncing people who share that priority must concur in the nomination. A person who does not want to participate may file an appropriate written renunciation.

Can a nonresident individual serve alone?

Yes, if otherwise qualified. Before letters, the nonresident files the resident service-and-notice agent designation required by § 473.117.

Does Missouri require a separate administrator oath before letters?

The cited ordinary opening provisions require the fiduciary undertaking in the application and an approved bond before duties, but do not add a separate personal-representative oath. Public administrators have a different office- holding oath outside this ordinary route.
