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.
Updated September 11, 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
Under RSMo section 473.050, presentment combines delivery to the proper Probate Division with a qualifying request or order. For an unavailable will, the statute allows a verified statement explaining its absence and known provisions. The accompanying document must be a petition for admission, a qualifying small estate affidavit requesting admission, or an authenticated order admitting the will elsewhere. Preserve filed copies and receipts.
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 | The later of six months after first publication or thirty days after commencement of a qualifying will-contest action under section 473.083, as section 473.050 provides. |
| 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 later of six months after probate or rejection of the will or six months after first publication of notice of Letters, together with standing, required notice, and service requirements under section 473.083. |
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.
Under RSMo section 473.083, the ordinary contest deadline is the later of six months after probate or rejection of the will or six months after first publication of notice of Letters. The statute also requires diligent service and addresses dismissal when service on all defendants is not completed within ninety days after filing without good cause. These are distinct requirements. Ask counsel to verify standing, notice, parties, filing, and service promptly.
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.
Build the timeline from filed records
The statutory clock depends on court events, not the day a relative first reads the will. Bring the order admitting or rejecting it, the first published notice of Letters, the original will and codicils, every filed petition, and any papers already served. Ask for the actual deadline calculation in the context of those records.
For example, admission of a will and first publication can happen on different dates. Section 473.083 compares the two six-month periods and uses the later one. That does not mean a family can wait until closing, rely on an informal objection, or omit required service after filing.
A will admitted in the deceased person’s domicile outside Missouri has a separate provision in RSMo section 473.050. Obtain the authenticated admission order and status of that domiciliary administration. If a will was properly presented within the applicable period, subsection 4 permits later proof and administration. These provisions are reasons to examine the file carefully, not to postpone presenting a newly found will.

Common questions
Missouri will and probate questions
Does a will avoid probate?
No. A will directs probate property and can nominate the person to administer it. A valid beneficiary designation, survivorship arrangement, funded trust, or another effective transfer may operate outside probate. Read the will together with the actual ownership records before deciding which procedure a particular asset needs.
Does the person named executor have authority immediately?
No. Nomination identifies whom the deceased person wanted to serve; court appointment and Letters establish the Personal Representative’s authority. Possession of the will does not authorize the nominee to use the deceased person’s funds or sign a sale contract for the estate. Preserve property and records while counsel determines the proper procedure.
What if only a copy of the will can be found?
Preserve the copy, prior versions, storage records, and information about who last held the original. An unavailable will raises proof questions and may require a verified statement satisfying section 473.050. A copy is neither automatically effective nor automatically worthless. Counsel must examine presentment, the reason for the missing original, and the available evidence.
Can all family members agree to use a will that was never timely presented?
Agreement cannot supply statutory authority that is missing. First establish whether a qualifying presentment actually occurred or a separate statutory provision applies. If the will is barred, counsel must identify the lawful succession and transfer procedure for each asset. The relatives should not sign court statements that assume the desired outcome.
How long does someone have to contest a will?
Section 473.083 generally uses the later of six months after probate or rejection of the will or six months after first publication of notice of Letters. Counsel must also examine standing, required notice, the proper parties, and service. The statute’s separate ninety-day service requirement can matter after a timely petition is filed.
Is an objection to an accounting the same as a will contest?
No. A will contest concerns which document constitutes the deceased person’s will. A dispute about an account, a proposed distribution, a transaction, or the Personal Representative’s conduct may require a different proceeding and deadline. Identify the challenged act and obtain the related notice and filed document before assuming one procedure protects every objection.
