If someone in your family died in Missouri and left assets behind, you have two main paths for settling what they owned. A small estate affidavit is the fast, low-cost path, and it works when the whole estate is worth $40,000 or less after debts. Full probate is the court-supervised path, and it is what you use for everything larger or more complicated. This guide explains the difference in plain terms, what Missouri law requires for each, and how to figure out which one fits your situation.
The short answer
Use the small estate affidavit when the estate is small and clean. Missouri lets the people who inherit collect the property with a signed, notarized affidavit filed with the probate court, and no personal representative has to be appointed. That saves months and a lot of money.
Use full probate when the estate is bigger, when there are disputes, when creditors need to be handled formally, or when the affidavit process simply will not reach the assets. Full probate is slower and costs more, but sometimes it is the only tool that does the job.
What the small estate affidavit is
Missouri’s small estate process lives in Section 473.097 RSMo. The statute lets the people entitled to inherit collect the property without waiting for the court to grant letters testamentary or letters of administration. In plain English, no one has to be formally appointed to run the estate. You file paperwork, and the assets can be released.
Two hard limits control whether you qualify:
- The value cap. The value of the entire estate, minus liens, debts, and encumbrances, cannot exceed $40,000. That is the net figure, not the gross. If the person owned a house with a small mortgage and little else, the equity is what counts against the cap.
- The waiting period. At least thirty days must have passed since the death, and no application for letters or for refusal of letters can be pending or already granted.
The statute also requires a bond in an amount not less than the value of the personal property, approved by the judge or clerk. For larger small estates, the court can require that notice be published so creditors get a chance to come forward. The exact steps vary a little by county, so call the probate division where the person lived before you file.
A will still matters here. Under Section 473.050 RSMo, a will is not effective until it is presented to and admitted by the probate court. The good news is that the small estate affidavit itself can request that the will be admitted, so you do not always need a separate full probate case just to honor the will.
What full probate is
Full probate is the court-supervised process of settling an estate. Someone gets appointed to act as the personal representative, and that person gathers the assets, pays the valid debts, and distributes what is left to the heirs or the people named in the will. We walk through the whole sequence in How to Probate a Will in Missouri.
It usually starts with an application for letters. Section 473.017 RSMo spells out what that application has to include, from the decedent’s information to the names of the heirs and the probable value of the property. If no one who is entitled to serve steps up, Section 473.020 RSMo lets any interested person petition the court, and it sets an outside deadline of one year after the date of death to open the estate.
Missouri offers two flavors of full probate. Independent administration runs with lighter court oversight and is common when the will allows it or the heirs agree. Supervised administration keeps the judge involved at more steps and is used when there is conflict or a reason to keep a close eye on the personal representative. Either way, it is more paperwork and more time than a small estate affidavit.
How to decide which one applies
Start with the math. Add up everything the person owned in their own name alone, subtract the debts and liens, and see where you land against the $40,000 net cap. Only assets that pass through the estate count. A bank account with a payable-on-death beneficiary, a vehicle titled to pass to a survivor, or land transferred by a beneficiary deed does not go through probate at all, so it does not eat into the cap.
That last point is where a lot of families win. If most of the property was set up to pass outside of court, the leftover estate may be small enough for the affidavit even when the person was not poor. We cover two common tools in How to Keep a Missouri Car Out of Probate and Lady Bird Deed or Beneficiary Deed in Adair County.
Then look at the complications. Fighting among heirs, unclear title, a business to wind down, or creditors who need to be forced to prove their claims can all push you toward full probate even when the dollar figure is modest.
Deadlines and creditor claims
Full probate has a built-in system for handling debts, and that is one reason to use it when creditors are a concern. Once letters are granted and notice is published, creditors have a limited window to file. Under Section 473.360 RSMo, most claims that are not filed within six months after the first published notice of letters are barred. Section 473.444 RSMo sets an outer limit, so claims that are never filed become unenforceable and forever barred.
That structure protects the heirs. When probate runs its course, the people who inherit take the property without worrying that an old creditor shows up years later. The small estate affidavit is faster, but it does not give you the same clean cutoff on debts, which is one more reason to think it through before you pick a path.
What it costs
The small estate affidavit is cheap. You are usually looking at a filing fee, the cost of a notary, and maybe a published notice. Full probate costs more because it runs longer and involves more work. Section 473.153 RSMo governs how the personal representative and the estate’s attorney are compensated, and those fees come out of the estate. For a large or contested estate that cost is worth it. For a small, simple one, it can eat up money that should go to the family, which is exactly why the affidavit exists.
Can you avoid probate altogether
Often, yes, and that is the smartest move if you are planning ahead rather than cleaning up after a death. A funded revocable living trust, beneficiary deeds on real estate, and payable-on-death or transfer-on-death designations on accounts and vehicles can move most property to your family without any court case at all. We explain how a trust holds up here in What It Takes to Make a Living Trust Stand in Adair County, and there is a broader walkthrough in our Missouri estate planning checklist.
Frequently asked questions
What is the dollar limit for a small estate in Missouri?
The net value of the entire estate, after subtracting liens, debts, and encumbrances, cannot be more than $40,000. If you clear that cap, you generally have to use full probate instead.
How long do I have to wait to file a small estate affidavit?
At least thirty days must pass after the death, and no one can have an application for letters or refusal of letters pending or already granted. Section 473.097 sets that waiting period.
Does a small estate affidavit work if there is a will?
Yes. A will is not effective until the probate court admits it, but the small estate affidavit can ask the court to admit the will at the same time, so you may not need a separate full probate case.
How long does full probate take in Missouri?
It varies, but it commonly runs several months to more than a year. The creditor claim window alone runs six months from the first published notice of letters, so even a smooth estate takes time to close properly.
What if more than a year has passed since the death?
Timing matters. Section 473.020 sets a one-year outside deadline to open an estate through the petition process, so waiting can cut off options. If you are past a year, talk to a probate lawyer quickly about what still works.
Do I need a lawyer for a small estate affidavit?
Not always, but it helps. The form looks simple, and the value cap and bond rules trip people up. A short review before you file can keep you from filing the wrong path and starting over.
