Estate Planning in Missouri: What Every Adult Needs to Know

Missouri's estate planning laws create both opportunities and traps that don't exist in most other states. The beneficiary deed (RSMo Section 461.025) lets you transfer real estate outside probate for a $24 recording fee. But if you die without a plan, Missouri's rigid intestacy formula can split your home between your spouse and children from a prior relationship — with zero room for adjustment.

Here's what a complete Missouri estate plan actually requires, in the order you should tackle it.

The Four Documents Every Missourian Needs

1. A Valid Will

Missouri requires a written will signed by the testator and two competent witnesses under RSMo Section 474.320. No oral, video, or holographic wills are recognized. Add a self-proving affidavit (RSMo Section 474.337) so the court can admit your will without hunting down witnesses.

Your will names a personal representative (executor), designates guardians for minor children, and distributes any assets that don't pass through non-probate transfers.

2. A Beneficiary Deed for Real Estate

Missouri pioneered the beneficiary deed — a transfer-on-death instrument that lets your home bypass probate entirely. You retain full control during your lifetime: you can sell, refinance, or revoke the deed at any time. The beneficiary has no rights until your death.

The deed must be signed, notarized, and recorded with the county Recorder of Deeds before your death. Recording fees run $24 for the first page plus $3 per additional page.

3. Durable Powers of Attorney

You need two separate documents:

• Financial durable power of attorney (RSMo Section 404.705): Appoints someone to manage your finances if you become incapacitated. Must explicitly state that authority survives incapacity.
• Healthcare power of attorney and directive (RSMo Section 404.800): Appoints a healthcare agent and states your end-of-life treatment preferences. Requires two adult witnesses plus notarization.

Without these, your family must petition for court-supervised conservatorship or guardianship — a process that costs $2,000 to $5,000 and takes months.

4. Non-Probate Designations on Everything Else

The goal is reducing your probate-eligible estate below Missouri's $40,000 small estate threshold:

• Bank accounts: Add payable-on-death (POD) designations
• Investment accounts: Add transfer-on-death (TOD) designations
• Vehicles: File Form 108 with the Missouri DOR to add a TOD beneficiary
• Retirement accounts and life insurance: Update beneficiary designations directly with the plan administrator

If your probate-eligible estate is $40,000 or less, your family can use the small estate affidavit (RSMo Section 473.097) instead of full probate — settling everything in 4 to 8 weeks.

Why Missouri Estate Planning Is Different

Common law property state. Unlike community property states where marital assets split 50/50 automatically, Missouri property belongs to whoever holds title. A house titled in one spouse's name alone goes through that spouse's estate — the surviving spouse doesn't automatically own half.

No state estate or inheritance tax. Missouri eliminated its estate tax for deaths after January 1, 2005. You only face federal estate tax if your estate exceeds the federal exemption ($15 million in 2026). For most families, death taxes are not a concern.

Strong spousal protections. Even if your will leaves your spouse nothing, they can elect against the will under RSMo Section 474.160 and claim one-third to one-half of the estate. Additional statutory allowances (homestead up to $15,000, exempt property, one year of family support) take priority over creditors and other heirs.

MO HealthNet estate recovery. If you received Medicaid long-term care benefits, Missouri will seek reimbursement from your estate under RSMo Section 473.398. A beneficiary deed does not protect against this — the state can pursue non-probate transfers if probate assets are insufficient to cover the claim.

The Cost of Not Planning

Traditional probate on a $300,000 Missouri home can cost $9,000 to $30,000 in attorney fees, court costs, personal representative bonds, and publication fees. The process typically takes 6 to 12 months.

By contrast, a coordinated estate plan using a will, beneficiary deed, and non-probate designations can transfer your entire estate outside probate for under $100 in recording and filing fees.

The Missouri Basic Estate Planning Kit walks you through all four documents with step-by-step instructions, an asset inventory worksheet, and a coordination checklist that ensures nothing falls through the cracks.
