Missouri Probate Explained: Timelines, Costs, and Shortcuts

Missouri probate is the court process, governed by RSMo Chapter 473, that transfers a deceased person's assets when those assets were titled in their name alone with no beneficiary attached. Many estates skip it entirely — anything held jointly, in a trust, or with a named beneficiary passes outside probate, and estates worth $40,000 or less can use a simple affidavit instead of full administration. Here's how to tell which situation you're in, and what to expect if you do need to open an estate.

When is probate required in Missouri?

Probate is required when the person who died owned assets in their sole name with no payable-on-death designation, no joint owner, and no trust — a house titled only to them, a solo bank account, a car, an investment account with no beneficiary. It doesn't matter whether there was a will; a will doesn't avoid probate, it just tells the probate court who gets what. If everything the person owned passes by beneficiary designation or joint title, you may never need to open a probate case at all, no matter how large the estate.

What assets skip Missouri probate?

Missouri's Nonprobate Transfers Law makes it one of the friendlier states for avoiding probate. Assets that pass outside the court process include property held in a living trust, jointly owned accounts and real estate with survivorship rights, life insurance and retirement accounts with living named beneficiaries, payable-on-death bank accounts, transfer-on-death titles on vehicles, and real estate covered by a Missouri beneficiary deed recorded before death. Check every account and deed before assuming probate is needed — a surprising number of estates turn out to be almost entirely nonprobate once you look.

Can you use a small estate affidavit in Missouri?

If the value of the entire estate, less liens, debt, and encumbrances, does not exceed forty thousand dollars, Missouri lets you collect and distribute the assets with a small estate affidavit instead of full administration. You must wait until thirty days have elapsed since the death of the decedent, and no personal representative can have been appointed or applied for. The affidavit is filed with the probate division of the circuit court in the county where the person lived, along with a filing fee set by statute.

A few details matter here. The statute calls for a bond in the amount of the property, except that the court may dispense with the filing of a bond if it finds that the same is not necessary. And when the value of the property listed in the affidavit is more than fifteen thousand dollars you must publish a notice to creditors once a week for two consecutive weeks in a local newspaper. Many probate clerks provide the forms and are used to walking families through this — it's a genuinely manageable process for a modest estate, often done without a lawyer.

What's the difference between independent and supervised administration?

Full Missouri probate comes in two flavors. Independent administration, which most estates use, lets the personal representative act largely without asking the court's permission — selling property, paying debts, and distributing assets — and it's available when the will authorizes it or the heirs and beneficiaries consent. Supervised administration means the court approves major steps and reviews annual settlements, which adds time and expense but provides oversight when family members don't trust each other or the estate is contentious. If you have a choice, independent administration is almost always faster and cheaper.

How long does Missouri probate take?

Plan on six months as a hard floor and nine months to a year as typical. Claims not filed within six months after the date of the first published notice of letters are barred — but read that section carefully, because a creditor who was actually mailed or served notice gets two months after the date such notice was mailed, or served, whichever later occurs, which can run past the six months. Claims are barred entirely one year following the date of the decedent's death. Estates with real estate to sell, tax complications, or family disagreements routinely run longer than a year. The personal representative also has early duties, including filing an inventory within thirty days after letters are granted, unless a longer time is granted by the court.

One deadline matters more than the rest, and it is not a flat year. Where no notice of letters has been published, a will must be presented within one year after the date of death of the testator. But where notice of the granting of letters has already been published, the window shortens to six months after the date of the first publication of the notice. Letters of administration are subject to their own limit: no letters shall be issued unless application is made within one year from the date of death, with exceptions including the wrongful-death route. If more than a year has passed, alternatives still exist — a determination of heirship is available if no administration has been commenced within one year after the date of decedent's death — but you have lost options, so don't let an estate sit untouched. Missouri also offers refusal of letters under RSMo 473.090, a shortcut where the personal estate does not exceed fifteen thousand dollars and there is no surviving spouse or unmarried minor children, or where the estate is no greater than the statutory allowances.

When do you actually need a probate attorney?

You can usually handle a small estate affidavit or a refusal of letters on your own, and probate clerks can tell you which forms apply, though they can't give legal advice. For full administration, hire a lawyer: many Missouri probate divisions effectively require personal representatives to have counsel for a full estate. Be careful with a common misunderstanding about cost. Missouri's statutory percentage schedule is a floor, not a ceiling — attorneys are allowed as the minimum compensation for their services sums equal to the percentages set forth in the schedule, and where reasonable compensation exceeds that minimum the court shall allow such additional compensation as will make the compensation of the attorneys reasonable and adequate. The schedule also runs on the value of the personal property administered and of the proceeds of all real property sold under order of the probate court, so a house that passes to heirs without being sold sits outside the fee base entirely. Ask for a written estimate rather than assuming the percentages are the whole bill.

The honest summary: check the beneficiary designations first, use the $40,000 affidavit if you qualify, choose independent administration if you don't, and expect the better part of a year. Probate in Missouri is slow, but it's a well-worn path, and thousands of families walk it every year without drama.
