Probating a will in Missouri means asking the probate division of the circuit court to declare the will valid and to appoint someone to settle the estate. You start by filing the original will and an application for letters with the court in the county where the person lived. From there the estate gets administered under court supervision until the debts are paid and what is left goes to the people named in the will.
If you are holding a parent or spouse’s will and wondering what to do next, this walks you through the process in the order you will actually face it, and the Missouri law that governs each step.
What “probate” really means
Probate is the court-supervised process of settling the estate of someone who died owning assets in their own name. A will does not avoid probate. A will tells the court who should be in charge and who inherits, but the will still has to go through the court to have legal effect.
Under Missouri law, a will is not effective until it is presented to and admitted by the probate court. Section 473.050 RSMo says it plainly: a will, to be effective as a will, must be presented for and admitted to probate. A will sitting in a drawer does nothing on its own.
This is the opposite of trust administration. If your loved one set up a funded living trust, most of their assets skip court entirely. We cover that separately in our guide to the Missouri trust administration process. Probate is for assets that were owned outright with no beneficiary designation and no trust holding them.
First deadline: get the will to the court
Missouri puts a hard clock on wills. Under Section 473.050 RSMo, if no letters have been granted and no notice given, the will must be presented within one year after the date of death. Miss that window and the will generally cannot be admitted. The estate then passes as if there were no will at all, under Missouri’s rules of descent in Section 474.010 RSMo.
One year sounds like plenty. It goes fast when a family is grieving and paperwork is scattered. Do not sit on the original will.
How to probate a will in Missouri, step by step
- Find the original will. The court wants the signed original, not a copy. Copies can be admitted, but it is a harder road. Check safe deposit boxes, home safes, and the drawer where important papers lived.
- Figure out which court. You file in the probate division of the circuit court in the county where the person lived. For Kirksville residents, that is the Adair County Circuit Court.
- File the will and an application for letters. The application asks the court to appoint a personal representative, the person who runs the estate. Section 473.017 RSMo lists exactly what the application has to state, including the decedent’s information, the heirs, and the nature and value of the property.
- Get appointed. If the will names an executor and the court approves, that person receives letters testamentary. Those letters are the legal proof of authority that banks and title offices will demand before they talk to you.
- Notify creditors and heirs. The estate publishes notice to creditors and gives notice to the people entitled to inherit.
- Inventory and manage the assets. The personal representative gathers the property, files an inventory, and safeguards everything until the estate closes.
- Pay debts, taxes, and expenses. Valid claims get paid in the order Missouri law sets.
- Distribute what is left and close. After debts and costs, the remaining property goes to the beneficiaries named in the will, and the court closes the estate.
What if nobody named in the will steps up?
Sometimes the person who should file just does not. Missouri accounts for that. Under Section 473.020 RSMo, if no application for letters is filed within twenty days after death by someone entitled to serve, any interested person can petition the court to open the estate and get the will admitted. A creditor with a real claim counts as an interested person. So the process does not stall forever just because the named executor is slow or unwilling.
The creditor clock you cannot ignore
Once the estate publishes its first notice of letters, a six-month window opens for creditors. Section 473.360 RSMo bars most claims that are not filed within six months after the date of that first published notice. This deadline protects the estate. It is one of the main reasons formal probate can be worth the trouble; it cuts off stale claims and gives the family a clean finish line.
Supervised versus independent administration
Missouri has two speeds. Supervised administration means the court signs off on the major moves. Independent administration lets the personal representative handle most of the work without asking the court’s permission at every turn, which is faster and cheaper.
Under Section 473.780 RSMo, independent administration is available when the will authorizes or directs it, or when all the heirs and beneficiaries agree to it. A well-drafted will usually asks for independent administration on purpose. When the estate is ready to close, the independent personal representative can petition for an order of complete settlement under Section 473.837 RSMo.
You might not need full probate at all
Small estates get a shortcut. Under Section 473.097 RSMo, if the total value of the estate is $40,000 or less and thirty days have passed since the death, the people entitled to inherit can collect the property using a small estate affidavit instead of opening a full probate case. No personal representative, no months of court supervision.
The same instinct drives a lot of good planning: keep assets out of probate before death so the family never has to file. We wrote about one common example, how to keep a Missouri car out of probate, and the logic extends to bank accounts and real estate with the right beneficiary tools.
Frequently asked questions
How long does probate take in Missouri?
A straightforward independent administration often runs somewhere in the six month to one year range, driven largely by the six-month creditor claim period in Section 473.360 RSMo. Contested wills, tax issues, or hard-to-value property stretch it out.
Do I need a lawyer to probate a will?
Missouri does not force you to hire one for the smallest matters, but most probate estates involve deadlines, notices, and personal liability for the personal representative. Getting it wrong costs more than getting help. If you are comparing local counsel, our piece on Adair County probate lawyer reviews explains what actually matters.
What happens if there is no will?
The estate still goes through probate, but the property passes under Missouri’s rules of descent in Section 474.010 RSMo rather than by anyone’s wishes. The surviving spouse and children take set shares defined by statute.
Can I be written out of a will?
A spouse cannot be fully cut out in Missouri. State law gives a surviving spouse an elective share regardless of what the will says. We break down the details in disinheriting a spouse in Missouri.
What is the deadline to file a will in Missouri?
Generally one year from the date of death when no letters have been granted, under Section 473.050 RSMo. If letters have already been granted and notice given, the window can be as short as six months. Do not wait to find out which one applies to you.
Does a small estate still need probate?
Not necessarily. An estate of $40,000 or less can be handled with a small estate affidavit under Section 473.097 RSMo once thirty days have passed since the death.
