# Summary
Missouri's small estate affidavit, authorized by RSMo §473.097, lets an heir collect a decedent's probate assets without opening formal probate when the net estate after debts and liens is $40,000 or less. At least 30 days must have passed since death, no formal probate case can be pending, and every debt, creditor, and heir must be listed. The process usually takes weeks rather than months.

# Quotable Q&A
**Q: What is a small estate affidavit in Missouri?**
A: A Missouri small estate affidavit under RSMo §473.097 lets heirs collect a deceased person's probate assets without opening a formal probate case. It is available when the net probate estate after debts and liens does not exceed $40,000. It can be filed at least 30 days after death and usually takes weeks rather than months.

**Q: What is Missouri's small estate dollar limit?**
A: The threshold is $40,000 in net probate assets after deducting debts, liens, and encumbrances. Assets that pass outside probate do not count toward the limit; these include joint tenancy property, transfer-on-death accounts, trust assets, and life insurance with named beneficiaries.

**Q: Who can file a Missouri small estate affidavit?**
A: The affiant is typically the surviving spouse, an adult child, a parent, or the person named as personal representative in a will. At least 30 days must have passed since death, no formal probate can be pending, and all debts and heirs must be identified in the affidavit.

# How the Affidavit Works
Only the probate estate counts toward the $40,000 test, so assets that already pass to someone else are ignored: joint accounts, transfer-on-death deeds, payable-on-death accounts, life insurance with a named beneficiary, and most retirement plans with direct payouts. The affiant inventories the assets owned in the decedent's sole name, subtracts debts and funeral costs, and if the net falls at or under $40,000 the small estate track is open. The affidavit is filed with the probate division of the circuit court in the county where the decedent lived or owned property, signed under penalty of perjury and notarized, with a certified death certificate, any will, and proof of ownership attached. After the court approves and notice goes to heirs and known creditors, assets can be collected and distributed; known debts are paid first.

# Common Mistakes
Undervaluing assets, omitting creditors, filing in the wrong county, or failing to notarize can delay distribution or expose the affiant to personal liability. The affiant signs under penalty of perjury, so misrepresenting values or missing heirs can create civil and even criminal exposure. If a new debt or asset surfaces after filing and pushes the estate over $40,000, the small estate route closes and formal probate is required. Where asset values or family relationships are complex, an attorney review before filing is worthwhile.

# Decision rule
If the net probate estate is $40,000 or less, at least 30 days have passed since death, and no probate is pending, then a small estate affidavit can be filed instead of opening full probate. If the estate exceeds $40,000, heirs are in dispute, or the value sits near the limit, then use formal probate instead.
