How do I make a valid will in Missouri?

Federal & State Law Editorial TeamLast reviewed: 2026-04-30

Missouri wills are governed by RSMo Chapter 474.

1. Testator Requirements

  • Age: 18 or older, or an emancipated minor (RSMo § 474.310).
  • Capacity: Sound mind.
  • 2. Witness Requirements (RSMo § 474.320)

  • In writing.
  • Signed by the testator (or by another in the testator's presence and by the testator's direction).
  • Attested by 2 or more competent witnesses subscribing their names to the will in the presence of the testator.
  • 3. Notarization

    Not required for validity. A self-proving affidavit (RSMo § 474.337) executed before a notary by the testator and witnesses allows the will to be probated without live witness testimony.

    4. Holographic Wills NOT Recognized in Missouri

    Missouri does not recognize holographic wills executed in Missouri. However, RSMo § 474.360 honors a will valid under the law of the place where executed or where the testator was domiciled.

    5. Nuncupative (Oral) Wills (RSMo § 474.340)

    Limited to soldiers in actual service or sailors at sea, for personal property only.

    6. Interested Witnesses

    A beneficiary-witness does not invalidate the will, but the gift is void unless 2 other disinterested witnesses signed (RSMo § 474.330).

    7. Intestacy (No Will)

    RSMo § 474.010: Spouse + descendants all of marriage — spouse takes first $20,000 + 1/2 of balance. Spouse + descendants from outside the marriage — spouse takes 1/2, descendants take 1/2.

    8. Small Estate Threshold

    Missouri's small estate procedure (RSMo § 473.097) is available for estates with assets not exceeding $40,000, after a 30-day waiting period.

    9. Nonprobate Transfers

    Missouri has a robust Nonprobate Transfers Law (RSMo §§ 461.003-461.081), allowing transfer-on-death deeds and beneficiary designations for many asset types.
