One of the most important reasons to make a will is to name your executor—sometimes called a "personal representative" in Missouri. After your death, your executor's primary job is to protect your property until any debts and taxes have been paid, and then transfer what's left to those who are entitled to it.

Every state has some rules about who may serve as the executor of an estate that goes through probate. Here are the requirements in Missouri.

Basic Requirements for Serving as a Missouri Executor

Your executor must be:

  • at least 18 years old, and
  • of sound mind—that is, not judged incapacitated by a court.

(Mo. Rev. Stat. § 473.117 (2024).)

Unlike states that prohibit people who have felony convictions from serving as executor, a person convicted of a felony in Missouri is eligible to serve after completing any prison sentence and all terms of parole. (Mo. Rev. Stat. §§ 1.020; 473.117 (2024).)

Special Rules for Executors in Missouri

In addition to the restrictions above, a Missouri probate court will reject a potential executor who is a full-time judge of any Missouri court or a clerk, deputy clerk, or division clerk of any court, unless this person is your surviving spouse or a relative within the third degree of kinship. For example, a judge of the Circuit Court of St. Louis County who is also your grandson could serve as your executor. (Mo. Rev. Stat. § 473.117 (2024).)

Furthermore, an executor of the person you name as your executor cannot become your executor. That's not as complicated as it sounds: Let's say you appoint your sister as your executor, but she dies while your estate is going through probate. Missouri law prevents the person your sister named as her executor from representing your estate. The job will go to your alternate executor or, if there's no alternate, to another person appointed by the probate court. (Mo. Rev. Stat. § 473.117 (2024).)

Finally, the court will not appoint someone to serve as your executor if he or she is found to be a "habitual drunkard." (Mo. Rev. Stat. § 473.117 (2024).)

Rules for Corporate Executors

Think carefully before appointing a bank or trust company to represent your estate. It's almost always best to name an individual; consider an institution only if you don't know anyone you trust enough to serve or your estate is very large and complex.

In Missouri, corporate executors must be authorized to act as a fiduciary. The company must be located in Missouri unless it files a written Application of Foreign Corporation for Certificate of Reciprocity with the Missouri Commissioner of Finance. (Mo. Rev. Stat. §§ 362.600, 473.117 (2024).)

Missouri Restrictions on Out-of-State Executors

For practical reasons, it's smart to name an executor who lives near you. Your executor may have to handle day-to-day matters for weeks, months, or sometimes longer. If you must appoint an executor who lives far away, you should know the requirements Missouri imposes on out-of-state executors.

In Missouri, a nonresident executor must appoint someone who lives in the state to act as a resident agent. Your executor's in-state agent will accept legal papers on behalf of your estate. (Mo. Rev. Stat. § 473.117 (2024).)

Conditions for an Executor's Removal

The probate court has the power to remove an executor if it receives a complaint or determines on its own that this person has become "incapable or unsuitable." Your executor could be removed if he or she:

  • is convicted of a felony
  • becomes mentally incapacitated
  • fails to perform any necessary duties
  • mismanages your estate
  • endangers any coexecutor
  • neglects to respond to any citation from the court, or
  • becomes a "habitual drunkard."

If this happens, the judge will terminate your executor's appointment and designate either your alternate executor or another suitable person as a replacement. (Mo. Rev. Stat. § 473.140 (2024).)
