Small Estate Affidavit vs. Full Probate in Missouri: Which Applies?
The small estate affidavit is a short court filing — a sworn affidavit, a bond or waiver, and a clerk's certificate, with no hearing — available when the whole estate, real and personal property together, is $40,000 or less after liens, debts and encumbrances (RSMo § 473.097). Over that line, or when letters have been applied for, full administration under Chapter 473 applies. A different filing, the determination of heirship (§ 473.663), covers the situation where nobody opened an estate within a year of death and the issue is proving who the heirs are rather than collecting property under a dollar cap. This is informational only and is not legal advice.

What makes Small Estate Affidavit different from full probate
The small estate affidavit is a short court filing — a sworn affidavit, a bond or waiver, and a clerk's certificate, with no hearing — available when the whole estate, real and personal property together, is $40,000 or less after liens, debts and encumbrances (RSMo § 473.097). Over that line, or when letters have been applied for, full administration under Chapter 473 applies. A different filing, the determination of heirship (§ 473.663), covers the situation where nobody opened an estate within a year of death and the issue is proving who the heirs are rather than collecting property under a dollar cap.
When an estate is pushed into full probate instead
- The estate exceeds the $40,000 (net value of the entire estate, real and personal property together, after liens, debts, and encumbrances) cap. Even one dollar over the statutory line under RSMo § 473.097 disqualifies small estate affidavit entirely — there's no partial or reduced-scope version of this mechanism for an estate just over the ceiling.
- The estate is over $40,000 net. The affidavit is limited to an estate of $40,000 or less after liens, debts and encumbrances, with real property counted.
- Letters or a refusal of letters has been applied for or granted. A pending or granted application for letters, for administration, or for refusal of letters blocks the affidavit unless the refusal was later revoked.
Why it's worth checking first: full probate is slower and typically far more expensive than small estate affidavit — a probate attorney typically charges $1,500–$4,200+ for the more limited process this guide covers, and full probate usually costs more and takes longer on top of that.
