What Qualifies for Missouri's Small Estate Affidavit?
Missouri's Small Estate Affidavit applies when the estate's value falls at or under $40,000 (net value of the entire estate, real and personal property together, after liens, debts, and encumbrances), under RSMo § 473.097. This is a statutory line, not a judgment call — compare your own total against it before assuming either way. This is informational only — we don't determine your eligibility for you.

The statutory line, exactly
Missouri's Small Estate Affidavit applies when the estate, measured the way the statute measures it, is at or under $40,000, under RSMo § 473.097. That figure specifically means: net value of the entire estate, real and personal property together, after liens, debts, and encumbrances. This is a statutory line, not a judgment call — the clerk or asset holder either sees your total under the cap or they don't. There's also a fixed 30-day waiting period after death before you can file at all — separate from the eligibility question, and it doesn't move regardless of how quickly you gather everything else.
The mistakes that actually sink an otherwise-eligible estate
6 reasons account for most of the rejections Missouri families run into — cited to the specific RSMo § 473.097 section behind each one, not general advice:
-
The estate is worth more than $40,000 after liens, debts and encumbrances. The affidavit must state that the value of the entire estate, real and personal property together, less liens, debt and encumbrances, does not exceed $40,000. A tenancy by the entirety or joint tenancy asset is not counted as the decedent's property. Circuit packets require supporting proof for any debt used to reach the figure. — RSMo § 473.097.1(1), .2(3)
-
Fewer than 30 days have passed, or letters or a refusal of letters is pending or was granted. The affidavit may be made only after thirty days from the death, and only if no application for letters, for administration, or for refusal of letters under § 473.090 is pending or has been granted (unless a refusal was later revoked). — RSMo § 473.097.1(2), .2
-
The will was not presented for probate in time, or the signer is not the right person. If there is a will, the affiant is the personal representative it names, and only if the will was presented within the § 473.050 limit — one year from death where no notice of letters was given. Without a will, any distributee entitled to receive property may sign. — RSMo § 473.097.2; § 473.050.3
-
No bond, or no valid waiver. A bond in at least the value of the personal property must be filed unless the court finds it unnecessary. What counts as enough to waive it differs by circuit. — RSMo § 473.097.1(3)
-
The affidavit leaves out a required item. It must say whether there was a will, that debts and estate taxes have been or will be paid (with the affiant's liability limited to what the affiant receives), give an itemized description and valuation of the property, name each person holding it, name and give the address and relationship of everyone who will receive each item, and state the facts establishing their right. The St. Louis County packet requires a complete list of heirs-at-law with their lineage. — RSMo § 473.097.2(1)-(6)
-
Fee paid but notice to creditors not completed. A filing fee under § 483.580 and, when the property listed is worth more than $15,000, the publication cost of the notice to creditors must be paid or proved to the clerk, with proof of publication filed within ten days after the notice runs. — RSMo § 473.097.1(4), .5
