Your complete Missouri estate planning overview: probate costs, will execution requirements, trust rules, and what happens if you die without a plan.
Missouri has statutory probate fees set by law as a percentage of the gross estate value — about $31,315 all-in on a $500,000 estate. Estates with personal property under $40,000 may qualify for Small Estate Affidavit.
Simple estates in Missouri typically take 6-12 months through probate. Complex or contested estates can take 1-3 years. A revocable trust avoids probate entirely.
Missouri has adopted the Uniform Trust Code and does not require witnesses for trust execution. Notarization is not required for validity, though many financial institutions require notarized trust documents. The successor trustee can publish Missouri's optional creditor notice to shorten the claim window to 6 months; without it, the settlor's creditors have up to 12 months to bring a claim.
Missouri offers remote online notarization (RON) for estate planning documents and transfer-on-death deeds to pass real estate without probate. These tools, combined with revocable trusts and beneficiary designations, provide multiple ways to transfer assets without probate.
A healthcare power of attorney in Missouri requires 2 witnesses and notarization to be valid. A financial power of attorney requires notarization. A financial power of attorney is not durable by default — it must include specific durability language to survive incapacity.
In Missouri, the executor must file an inventory of the estate's assets within 30 days of appointment. A revocable trust skips the court-supervised inventory entirely, so a trustee distributes assets without filing one.
In Missouri, divorce automatically revokes a beneficiary designation that names a former spouse on covered accounts, so the asset does not pass to the ex-spouse unless the designation is renewed after the divorce.
