Missouri Probate Law: Estates, Wills, and the Probate Process

Missouri probate law governs the formal legal process by which a deceased person's estate is administered, debts are settled, and assets are transferred to heirs or beneficiaries. This area of law is primarily codified under the Missouri Revised Statutes, Chapters 472 through 475, which establish the jurisdiction of probate divisions, the validity requirements for wills, and the procedural framework for estate administration. Probate intersects with Missouri property law, Missouri family law, and Missouri contract law, making it a structurally significant sector of the state's civil legal landscape.

Definition and Scope

Probate in Missouri is the court-supervised process of authenticating a decedent's will (if one exists), appointing a personal representative, inventorying estate assets, paying valid creditor claims, and distributing remaining assets to rightful beneficiaries or heirs. The Missouri probate division operates as a specialized division within the circuit court system — the same trial-level courts described in the Missouri Circuit Courts reference — and each of Missouri's 45 circuits maintains a probate division.

The governing statutory framework is Chapter 472 of the Missouri Revised Statutes (RSMo), which defines jurisdiction and general probate powers. Chapter 473 RSMo covers administration of decedents' estates, and Chapter 474 RSMo codifies Missouri's probate code, including intestate succession rules. The Missouri Supreme Court publishes local court rules applicable to probate proceedings statewide.

Scope limitations: This page addresses Missouri state probate law exclusively. Federal estate tax obligations — administered by the Internal Revenue Service under 26 U.S.C. § 2001 et seq. — fall outside Missouri probate court jurisdiction, though they interact with large estate administrations. Tribal estate matters handled under sovereign tribal authority are not covered here. Estates involving real property located in other states require ancillary probate proceedings under those states' laws, which this page does not address.

How It Works

Missouri probate administration follows a defined procedural sequence. The process differs based on whether the decedent left a valid will (testate) or died without one (intestate), and whether the estate qualifies for simplified procedures.

Standard probate administration — key phases:

  1. Filing the petition: An interested party petitions the circuit court's probate division in the county where the decedent was domiciled. The original will (if any) must be filed within 30 days of the decedent's death under RSMo § 473.050.
  2. Appointment of personal representative: The court appoints an executor (named in the will) or an administrator (appointed by the court in intestate cases). The personal representative is required to post a bond unless the will waives it or all heirs consent to waiver.
  3. Inventory and appraisal: The personal representative must file a verified inventory of all probate assets within 30 days of appointment under RSMo § 473.233.
  4. Notice to creditors: Missouri law requires publication of a notice to creditors for 6 consecutive months (RSMo § 473.360), during which creditors may present claims against the estate.
  5. Payment of debts and taxes: Valid creditor claims, funeral expenses, estate administration costs, and applicable taxes are paid before distributions to beneficiaries.
  6. Final settlement and distribution: The personal representative files a final settlement with the court, which, upon approval, authorizes asset distribution to heirs or beneficiaries per the will or Missouri's intestate succession statutes.

Small estate procedures: Missouri provides two abbreviated paths for smaller estates. A refusal of letters (RSMo § 473.097) is available when the gross estate value does not exceed $40,000. A small estate affidavit process allows certain asset transfers without full probate when the estate falls below this threshold. These mechanisms substantially reduce court involvement and administration time compared to standard probate.

Common Scenarios

Testate estates (decedent left a will): Missouri requires wills to be in writing, signed by the testator (or by another person at the testator's direction in the testator's presence), and witnessed by 2 credible witnesses per RSMo § 474.320. Holographic wills — entirely handwritten and signed by the testator — are valid in Missouri under RSMo § 474.320 without witness requirements. Self-proved wills, executed with notarized affidavits, expedite probate by eliminating the need to locate witnesses for court testimony.

Intestate estates (no valid will): When a Missouri decedent dies without a will, RSMo § 474.010 establishes the distribution hierarchy. The surviving spouse receives specific shares depending on whether the decedent had descendants from outside the marriage. Descendants inherit per stirpes if no surviving spouse exists. Absent descendants or a spouse, assets pass to parents, then siblings, under the statutory scheme.

Contested wills and will challenges: Missouri courts recognize challenges based on lack of testamentary capacity, undue influence, fraud, or improper execution. Such contests are filed in the probate division and are governed by RSMo § 473.083, which sets a 6-month window from the date of the first publication of letters testamentary to file a will contest.

Trusts and non-probate transfers: Assets held in a revocable living trust, payable-on-death accounts, joint tenancy property, and beneficiary-designated accounts (such as IRAs and life insurance) pass outside probate entirely. Missouri's non-probate transfers law, RSMo Chapter 461, governs these mechanisms and represents a significant parallel pathway to probate administration.

Decision Boundaries

Probate vs. non-probate estate planning: The core structural distinction in Missouri estate administration is between assets subject to probate court supervision and those that transfer by operation of law. Real property held in joint tenancy with right of survivorship, for instance, passes automatically to the surviving co-owner without probate. Conversely, solely owned real property titled only in the decedent's name will require probate regardless of estate size (unless placed in a trust prior to death).

Supervised vs. unsupervised administration: Missouri probate allows personal representatives to petition for independent (unsupervised) administration under RSMo § 473.780 when the decedent's will authorizes it or all interested parties consent. Supervised administration requires court approval for each significant estate action, while independent administration consolidates court involvement to opening and closing stages.

Estate tax thresholds: Missouri does not impose a state-level estate tax as of the repeal of Missouri's estate tax, which was tied to the federal credit for state death taxes phased out under federal law. Federal estate tax applies to estates exceeding the federal exemption — $13.61 million per individual for 2024 per the IRS Estate Tax Overview — meaning most Missouri estates face no estate tax liability at either level.

Professional representation requirements: While Missouri law does not mandate attorney representation in probate proceedings, the complexity of contested estates, multi-jurisdictional assets, or estates involving minor beneficiaries regularly requires licensed legal counsel. The Missouri Bar maintains a lawyer referral service, and qualification standards for Missouri attorneys are addressed in Missouri Bar Admission.
