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.
