Missouri Last Will and Testament Laws and Requirements

A last will and testament in Missouri must meet specific statutory requirements to be valid and enforceable in probate court. The testator must properly execute the document with the correct number of witnesses to ensure it directs the distribution of estate assets to named beneficiaries and appoints an executor to administer the estate. Missouri imposes specific execution requirements for a valid last will and testament, including witness requirements, rules on holographic wills, and provisions for self-proving affidavits that streamline the probate process.

Without a valid will, Missouri intestate succession laws determine who inherits — often in ways that contradict the decedent's wishes. A surviving spouse may receive only a portion of the estate, unmarried partners receive nothing, and a court appoints an administrator instead of the testator's chosen executor. Proper execution under Missouri law prevents these outcomes and reduces the risk of a will contest. A complete estate plan typically pairs a will with a power of attorney for lifetime incapacity protection.

Missouri Last Will and Testament Requirements

Witnesses: Missouri typically requires two disinterested witnesses to attest the testator's signature.

Holographic wills: Check whether Missouri recognizes handwritten (holographic) wills — approximately half of U.S. states do.

Self-proving affidavit: Most states allow a self-proving affidavit signed before a notary to streamline probate.

Notarization: Generally not required for the will itself in Missouri, but may be required for the self-proving affidavit.

Capacity: The testator must have testamentary capacity at the time of signing under Missouri law.

Revocation: A will can be revoked in Missouri by a subsequent will, physical destruction, or operation of law.

Missouri Last Will and Testament FAQ

How many witnesses do I need for a will in Missouri?
Missouri typically requires two witnesses to attest the testator's signature. Witnesses should be "disinterested" — meaning they are not beneficiaries under the will, as a beneficiary-witness may forfeit their inheritance under Missouri law.
Does Missouri recognize holographic (handwritten) wills?
Whether Missouri recognizes holographic wills depends on state statute. Approximately 26 states recognize them. Even where permitted, a formally witnessed will is always more reliable because it is harder to contest. Use our will generator to create a properly formatted, witnessed document.
Does a will need to be notarized in Missouri?
Most states do not require notarization of the will itself, but a notarized self-proving affidavit is strongly recommended. A self-proving affidavit eliminates the need for witnesses to testify in probate court, which significantly speeds up the process.
What happens if you die without a will in Missouri?
If you die without a will (intestate) in Missouri, state intestacy laws determine who inherits. Typically, your spouse and children inherit in proportions set by Missouri statute. Unmarried partners, close friends, and charities receive nothing. A Missouri court will appoint an administrator and, if you have minor children, a judge decides guardianship. This process is public, slow, and costly. Download our last will template to prevent this.
Can I write my own will without a lawyer in Missouri?
Yes, you can legally create your own will in Missouri as long as it meets the state's execution requirements (proper witnesses, signatures, and capacity). Legal Tank's AI will generator asks the right questions and ensures Missouri-specific compliance. For complex estates with business interests, significant tax considerations, or blended families, consulting a Missouri attorney is advisable.
