Are Holographic and Oral Wills Legal in Missouri? Requirements & Exceptions

Current as of: October 4, 2026 Wills & Last Testaments Missouri
In Missouri, a handwritten will is not legally valid unless it is signed by two competent witnesses. Strict execution rules apply, and oral wills are severely limited.

Creating a Last Will and Testament is the cornerstone of protecting your family's future. Many people in cities like St. Louis, Kansas City, and Springfield believe they can simply write their wishes on a piece of paper or tell a loved one what to do. However, Missouri probate courts are incredibly strict. A minor mistake can completely invalidate your wishes, leaving your estate to be distributed according to default state laws. If you need help ensuring your estate plan is ironclad, you can find an experienced local probate lawyer in our US Lawyers Directory.

Strict Execution Requirements Under Missouri Law

In Missouri, the creation and validity of a will are governed by Mo. Rev. Stat. § 474.320. This statute mandates that every traditional paper will must be in writing, signed by the testator (the person making the will), and attested by two or more competent witnesses who sign in the physical presence of the testator. While the Missouri Electronic Wills and Electronic Estate Planning Documents Act (Mo. Rev. Stat. § 474.540 through Mo. Rev. Stat. § 474.564) authorizes electronic wills and remote witnessing via real-time audio-visual communication, conventional paper wills demand strict physical compliance. The precedent-setting case Hodges v. Hodges, 692 S.W.2d 361 (MO Court of Appeals 1985) reinforced that courts cannot simply overlook statutory execution requirements, no matter how clear the deceased person's intentions might seem.

The Risks of Handwritten Wills Drafted Without a Lawyer

A handwritten will is often called a 'holographic' will. In several US states, a will written entirely in the testator's own handwriting is valid even without witnesses. This is not the case in Missouri. Missouri does not recognize unwitnessed holographic wills. If you write out your final wishes on a legal pad in your kitchen, you must still gather two competent witnesses to watch you sign it, and they must sign it as well. If you fail to do this, a judge at the Jackson County Circuit Court, Probate Division, Kansas City or the St. Louis County Circuit Court, Probate Division, Clayton will reject the document when your family submits an Application for Probate of Will accompanied by Form FI-50, Missouri, Circuit Court, Confidential Case Filing Information Sheet - Probate and Non-Domestic Relations.

Nuncupative (Oral) Wills for Active Military Members

An oral will, legally known as a nuncupative will, is when a person speaks their final wishes aloud rather than writing them down. Under Mo. Rev. Stat. § 474.340, oral wills are strictly restricted in Missouri, with no special exceptions or expanded property thresholds for active-duty military members or mariners at sea. A nuncupative will is valid only if the person is in imminent peril of death and actually dies as a result of that impending peril. Furthermore, it must be declared before two disinterested witnesses, reduced to writing within 30 days, and submitted for probate within six months. Even then, an oral will can only transfer personal property up to an aggregate value of $500 and cannot revoke or modify a prior written will. The only military-specific exception under Missouri probate law is found in Mo. Rev. Stat. § 474.310, which grants minors emancipated by entry into active military duty the legal capacity to execute a standard written will.

Why DIY Will Kits Fail Statutory Compliance

Many people attempt to save money by purchasing generic DIY will kits online or at a local office supply store. While these templates seem convenient, they often fail to comply with Missouri-specific statutes. A common mistake is failing to include a proper 'self-proving affidavit.' Without a notarized self-proving affidavit attached to the will, your witnesses will be required to physically appear in probate court or submit sworn testimony after you die. If years have passed and your witnesses cannot be located, your DIY will might be thrown out entirely.

Frequently Asked Questions (FAQ)

Does a will in Missouri have to be notarized to be valid?

No, a will does not strictly require a notary to be valid. However, having a notary sign a 'self-proving affidavit' at the end of the will is highly recommended because it prevents the witnesses from having to testify in court later.

Who can serve as a witness to a will in Missouri?

A witness must be at least 18 years old and competent. While it is best practice for witnesses to be 'disinterested,' having a beneficiary witness a will does not automatically void the entire bequest. Under Missouri's purging statute, Mo. Rev. Stat. § 474.330, an interested witness only forfeits the portion of their inheritance that exceeds the intestate share they would have received under default state law, unless two additional disinterested witnesses also attest to the will.

What happens if I die without any valid will?

If you die without a valid will, you die 'intestate.' Missouri intestacy laws will automatically dictate who inherits your property, which generally prioritizes your surviving spouse and children, regardless of what your actual wishes were.

Can a video recording count as a will?

No. Missouri law requires a will to be in writing. A video recording expressing your wishes has no legal binding effect in probate court, though it could potentially be used as secondary evidence to prove you were of sound mind.
