How long does probate take in Missouri?

Published June 3, 2026 4 min read

Quick answer

Roughly 9 to 15 months for a routine estate; the law requires a minimum six-month creditor claim period that cannot be shortened, so a full estate almost never closes faster than about six to nine months.

Why probate takes that long

The single biggest factor that sets the floor on probate timing is the creditor claim period — the window during which people the decedent owed money must come forward.

In Missouri: Six months from the date of first published notice of letters, under Mo. Rev. Stat. Ch. 473. Claims not filed within this period are forever barred. This minimum period cannot be shortened.

Until that window closes (or is otherwise resolved), the personal representative generally can’t safely distribute the estate to heirs. That’s why even the simplest Missouri probate rarely finishes faster than the creditor period itself.

What can make Missouri probate faster

  • Small-estate procedure. Estates valued at $40,000 or less (after liens and encumbrances) qualify for a small estate affidavit under Mo. Rev. Stat. §473.097, available 30 days after death. Above $15,000, the clerk must publish a notice to creditors.
  • Simplified real-estate procedure. Real estate that passes directly to heirs or by beneficiary deed is excluded from the statutory fee base, since fees apply only to personal property administered and real estate actually sold under court order.
  • A funded living trust. Assets held in a properly funded revocable living trust skip probate entirely. The successor trustee can usually distribute the trust assets privately within a month or two.
  • Beneficiary designations and joint ownership. Life insurance, retirement accounts, payable-on-death (POD) accounts, and jointly held property pass directly to the named person and never enter probate.
  • Cooperation among heirs. Uncontested probate moves dramatically faster than estates where heirs disagree.

What can make Missouri probate slower

  • A contested will or family dispute. Will contests can add 6 to 24 months — sometimes years.
  • Real estate that has to be sold. Listing, accepting an offer, and closing on a property routinely adds 3 to 6 months.
  • A federal estate tax return. Estates over the federal exemption ($13.99M per person in 2025) must file IRS Form 706 within 9 months. The IRS review can take a year or more.
  • State estate or inheritance tax. Where applicable (Pennsylvania has an inheritance tax; several other states still have estate taxes), the state’s tax review can extend the timeline.
  • Out-of-state property. Real estate owned in another state typically requires a separate ancillary probate in that state, in parallel.
  • Missing or unreachable heirs. The personal representative must take reasonable steps to locate beneficiaries before closing.
  • Complex assets — business interests, partnership stakes, intellectual property, art collections — which require professional valuation.

When can the executor safely distribute?

In a typical, uncontested Missouri estate with no surprises, the personal representative can usually begin distributing assets after the creditor claim period closes and any required tax returns clear. For most Missouri families, that means plan on roughly the timeline above, and don’t promise heirs specific dates earlier than that.

If the estate qualifies for Missouri’s small-estate procedure or a simplified administration, distribution can happen much faster — sometimes within weeks of death.

The honest takeaway

The shortest path through probate in Missouri is the one you set up before anyone dies — by titling assets correctly, keeping beneficiary designations current, and, where it makes sense, using a living trust. Once probate has started, the timeline is largely set by the creditor period and the speed of the local court.

If you’re an executor staring down a Missouri probate today, the single most useful thing you can do this week is gather the documents (the will, account statements, deeds, beneficiary designations) and talk to a licensed Missouri probate attorney about whether full probate is even required, or whether a small-estate procedure will do the job.
