Find the original
The signed original is ordinarily the starting document. Copies are useful evidence but can create additional proof issues when the original cannot be located.

MISSOURI WILLS AND PROBATE
Wills, Presentment, and Will Contests in Missouri Probate
A will can control who receives probate property and who is nominated to serve, but it does not create immediate authority and it does not protect itself from Missouri’s filing deadlines.
Reviewed September 1, 2026
WHAT A WILL ACTUALLY DOES
A will governs probate property. It does not automatically avoid probate.
A Missouri will can identify beneficiaries, nominate a Personal Representative, authorize or prohibit independent administration, create testamentary trusts, allocate taxes or expenses, and provide other instructions for property that passes through the probate estate.
The will does not override a valid beneficiary designation, survivorship deed, beneficiary deed, trust ownership, payable-on-death designation, or other effective nonprobate transfer. Those ownership records are analyzed first. The will controls what remains in the probate estate.
The nominee is not yet the Personal Representative
A person named as executor in a will has priority to seek appointment in many cases, but the will itself does not issue Letters. The Probate Division appoints the Personal Representative. General probate authority begins with the court appointment and the Letters, not merely with possession of the original will.
PRESENTING THE WILL
Keeping the original in a safe does not preserve the probate deadline.
Identify the proper Probate Division
Venue ordinarily begins with the deceased person’s domicile at death. A nursing-home stay or temporary residence does not automatically change domicile.
Present the will in the manner Missouri law recognizes
Delivery must satisfy the probate statute. The attorney preserves the file stamp, case number, petition or affidavit, and other evidence showing when presentment occurred.
Separate presentment from the application for Letters
Presenting a will preserves one issue. Applying for Letters seeks authority to administer the estate. The two acts have related but distinct statutory consequences and should not be treated as interchangeable.
THE DEADLINE MAP
The one-year rule is critical, but it is not the only will deadline.
| Event | What the attorney checks |
|---|---|
| No estate opened and no notice of Letters published | Whether the will was properly presented within one year after death and whether an application for Letters was timely made. |
| Letters already issued and notice published | Whether the shorter statutory period tied to first publication controls the time to present another will. |
| Will timely presented but proof or administration occurs later | Whether the court record establishes timely presentment and what further proceeding remains available. |
| More than one year has passed without timely action | Whether ordinary Letters and admission of the will are barred and whether an heirship, small-estate, nonprobate, or other asset-specific procedure remains. |
| Someone wants to challenge the admitted will | The separate will-contest deadline, who has standing, what judgment admitted or rejected the will, and when the statutory contest period began. |
MISSING ORIGINALS
A copy of a will is not automatically treated the same as the signed original.
When an original will was last in the deceased person’s possession and cannot be found after death, the circumstances can raise questions about revocation. When the original was held by another person, a lawyer, a financial institution, or another custodian, the evidentiary analysis may be different.
The attorney investigates where the original was stored, who had access to it, whether later wills or codicils exist, whether the deceased person discussed destroying or changing the document, and what witnesses or other proof are available. A family should preserve every copy and every estate-planning file rather than assuming the copy either definitely controls or definitely has no value.
Do not create evidence problems
Do not write on the original, remove staples, separate pages, discard envelopes, or circulate the document unnecessarily. Preserve the condition in which it was found and let the probate attorney determine what must be filed.
WHO SERVES
The will can nominate the Personal Representative and shape the administration.
A valid will often names the person the deceased wanted to serve. The court still determines whether that person is qualified and enters the appointment. If the nominee cannot or will not serve, the will may name successors; otherwise Missouri’s statutory priority rules guide the appointment.
The will also can direct independent administration or require supervision. That decision affects how much advance court approval the Personal Representative needs for administration acts, although it does not eliminate fiduciary duties, notices, records, claims work, distribution requirements, or legal advice.
WILL CONTESTS
A disagreement about fairness is not the same as a legal basis to contest a will.
A will contest is a court proceeding challenging whether the document admitted or rejected by the Probate Division should control. Possible legal issues can include testamentary capacity, undue influence, improper execution, revocation, fraud, or the existence of a later valid will. The facts and available evidence determine whether a claim exists.
Missouri imposes a short statutory period for a will contest. A person who receives notice of probate and believes the will is invalid should obtain legal advice promptly rather than waiting for the estate to approach distribution.
Capacity
The issue is not whether the person was old, ill, forgetful, or had a diagnosis. The legal inquiry focuses on testamentary capacity at the time the will was executed.
Undue influence
Influence is not automatically improper. The evidence must support a legal basis for concluding the document resulted from influence that overcame the person’s free agency.
Execution
Missouri formalities matter. The attorney examines signatures, witnesses, attestation language, self-proving affidavits, and the circumstances of execution.
Revocation or later documents
A later will, codicil, physical act, or other legally effective revocation can change which document controls. Every version should be preserved for review.
THE WILL AND THE ASSET LIST
Even a perfectly valid will cannot distribute property the deceased person did not own through probate.
The attorney reads the will together with the deed, account contracts, beneficiary records, trust documents, vehicle titles, business records, and other ownership evidence. This prevents a common mistake: interpreting a gift in the will before confirming whether the described property is actually part of the probate estate.
If the will says “I give my house to my daughter,” but a valid beneficiary deed already transfers that same house to someone else at death, the deed may control the nonprobate transfer. If an account names a living payable-on-death beneficiary, that contract may control instead of the residuary clause. Probate interpretation begins with ownership.
COMMON QUESTIONS
Missouri will and probate questions
Does a will avoid probate?
No. A will directs probate property. Property avoids probate because another valid ownership or beneficiary arrangement transfers it outside the probate estate.
Does the person named executor have authority immediately?
No. The will nominates the person. The Probate Division appoints the Personal Representative and issues Letters that establish probate authority.
What if only a copy of the will can be found?
Preserve the copy and obtain legal review. Whether the will can be established depends on the circumstances surrounding the missing original and the evidence available.
Can all family members agree to use a will that was never timely presented?
Family agreement cannot give the court authority that Missouri’s limitation statutes withhold. The attorney must identify what legal transfer procedure remains for each asset.
How long does someone have to contest a will?
Missouri uses a separate statutory contest period tied to the judgment admitting or rejecting the will and the required notice. Because the period is short and fact-specific, a potential contestant should obtain advice immediately.
