Where to File a Missouri Will and Testament

Filling out a last will and testament is a meaningful step, but the document has no legal effect until it reaches the right place. If you're wondering where to submit Missouri will and testament forms, you're not alone this is one of the most common questions people have after completing their paperwork. Submitting your will to the wrong office, or not submitting it at all, can cause serious delays for your family when the time comes to settle your estate. Knowing the correct filing location saves time, prevents confusion, and protects the wishes you've put in writing.

Where exactly do you file a will in Missouri?

In Missouri, a last will and testament is filed with the probate division of the circuit court in the county where the person who wrote the will (the testator) lived at the time of death. Every Missouri county has a probate division that handles estates, wills, and related matters. This is the only court with authority over the probate process in the state.

For example, if the testator lived in Greene County, the will goes to the Greene County Circuit Court, Probate Division. If they lived in St. Louis County, it goes to the St. Louis County Probate Court. You cannot file in a different county simply because it is more convenient.

Do you file a will before or after someone dies?

You can do both, but the rules are different for each situation.

After death: Missouri law (specifically RSMo § 473.050) requires that any person in possession of a will must file it with the probate court within a reasonable time after learning of the testator's death. This applies whether or not you plan to open a formal probate case. Failing to file a known will is a violation of Missouri law.

Before death: Missouri also allows you to deposit your will with the probate court for safekeeping while you are still living. Under RSMo § 473.150, you can deliver your will to the clerk of the probate court in the county where you reside. The court holds it in a sealed envelope, and it stays there until you retrieve it or it is opened after your death. There is usually a small deposit fee for this service.

If you want to understand the broader process of how to file testament forms in Missouri probate court, knowing the timing rules is an important first step.

Which Missouri probate court handles your will?

The answer depends on the decedent's domicile the county where they officially lived. Missouri has probate divisions in every circuit court across its 45 judicial circuits. Here are a few common scenarios:

Testator lived in Jackson County: File with Jackson County Probate Division in Independence or Kansas City.
Testator lived in Boone County: File with Boone County Probate Division in Columbia.
Testator owned property in multiple counties: The will is still filed in the county of residence. Ancillary proceedings may be opened in other counties if real estate is involved.
Testator moved to Missouri late in life: File in the county where they were living at the time of death, even if they lived elsewhere recently.

What do you need to bring when filing a will?

When you go to the probate court to file, bring these items:

The original signed will. Courts in Missouri generally need the original document, not a photocopy. If only a copy exists, you may need to petition the court to admit it, which adds cost and delay.
A certified copy of the death certificate. Most courts require this at or shortly after filing.
A filing fee. Fees vary by county but typically range from around $50 to $150. Contact the specific court ahead of time to confirm the amount and accepted payment methods.
Identification. You'll likely need a valid photo ID if you are filing in person.

Some counties in Missouri also accept filings by mail. If you cannot visit the courthouse, call the clerk's office to ask whether they accept mailed submissions and what the requirements are.

Can you file a will online in Missouri?

As of now, Missouri courts do not have a statewide system for electronically filing original wills. Most probate courts still require you to deliver the physical original document. Some courts may have limited e-filing for other probate motions and documents, but the will itself typically needs to be a paper original.

Always check with your specific county's probate clerk before assuming you can file online. Court procedures can differ from one county to another.

What happens after the will is filed?

Once the will is filed with the probate court:

The court clerk records the filing and keeps the will in the case file.
If a probate case is opened, the court may admit the will to probate after a hearing or review.
The court may appoint a personal representative (executor) named in the will to manage the estate.
Interested parties, such as beneficiaries and heirs, receive notice of the proceedings.
The personal representative begins collecting assets, paying debts, and distributing property according to the will.

If you are handling this process for a blended family, the probate court requirements for blended family wills may involve additional considerations around stepchildren and inheritance rights.

What are common mistakes people make when submitting a will?

A few errors come up frequently and can cause real problems:

Keeping the will at home instead of filing it. A will that nobody finds is essentially useless. Some families discover a will months or years after a death or never find it at all.
Filing in the wrong county. The court where you file must be in the county of the testator's residence. Filing elsewhere can lead to rejection or delays.
Submitting a copy instead of the original. Missouri courts strongly prefer original wills. Copies are much harder to admit and may require additional court hearings with witness testimony.
Waiting too long to file. Missouri law says a will must be filed within a reasonable time after death. There is no specific deadline in days, but prolonged delays can raise legal questions and increase the risk of disputes.
Assuming the attorney will handle it automatically. Many people believe the lawyer who drafted the will takes care of filing. That is not always the case. Confirm with your attorney who is responsible for delivering the will to the court.

How much does it cost to submit a will to a Missouri court?

The filing fee for depositing a will or opening a probate case varies by county. Typical costs include:

Safekeeping deposit (before death): Usually a nominal fee, often $5 to $25.
Probate filing fee (after death): Generally $50 to $150, depending on the county and estate size.
Additional costs: Certified copies, publication fees for legal notices, and court costs may add to the total.

What if you need help completing your will before filing?

Before you can file a will, it needs to be properly drafted and executed. Missouri has specific requirements for a valid will:

The testator must be at least 18 years old and of sound mind.
The will must be in writing.
It must be signed by the testator (or by someone at the testator's direction).
It must be witnessed by at least two competent individuals who also sign the will.
