Missouri Penalty for Not Filing Satisfaction of Judgment (RSMo 511.620)

You collected every dollar owed on your Missouri small claims judgment. Now what? If you think you can pocket the payment and move on, RSMo § 511.620 says otherwise — and the penalty for ignoring it can cost you more than the original judgment was worth.

The 50-Day Period After Written Demand

Under RSMo § 511.570 and Supreme Court Rule 74.11, once a judgment is fully satisfied (principal, court costs, and post-judgment interest), the judgment creditor must promptly file an Acknowledgment of Satisfaction of Judgment with the circuit clerk. If the creditor fails or refuses to do so within 50 days after the debtor's written demand, the debtor may seek an order of satisfaction under Rule 74.11(c).

Here's how the clock works:

1. The debtor pays the full judgment balance.
2. The debtor (or their attorney) sends a written demand to the creditor asking them to file a satisfaction.
3. If the creditor has not filed the satisfaction within 50 days after receiving that demand, the debtor may ask the court for an order declaring the judgment satisfied.

The satisfaction filing tells the court — and the public record on Case.net — that the debt is paid and the judgment is no longer enforceable. Until it's filed, the judgment stays on record as active and unsatisfied.

What Happens If You Don't File

An unreasonable refusal to file after formal demand may expose a creditor to statutory penalties under RSMo § 511.620. Under Rule 74.11(c), after 50 days following written demand the debtor may move for an order of satisfaction. If the court finds the judgment has been satisfied, it may assess court costs and attorney fees against the creditor.

Beyond possible statutory penalties, court costs, and attorney fees, an unsatisfied judgment causes real problems:

• A recorded lien can complicate a sale or refinance. If you filed a judgment lien, the debtor may need the lien addressed or released even though the debt has been paid.
• The court can compel filing. The debtor can petition the court to enter a satisfaction on the docket over your objection. You'll also be paying the debtor's court costs for the motion.
• You lose credibility. If you're a business that regularly uses small claims court to collect invoices, failing to file satisfactions signals bad faith to judges who see your name on future filings.

How to File the Satisfaction

Filing a satisfaction in Missouri is straightforward:

1. Prepare a written Acknowledgment of Satisfaction of Judgment stating the case number, parties, and that the judgment has been paid in full.
2. Sign the acknowledgment (notarization may be required by some circuit clerks — check your county's local rules).
3. File it with the circuit clerk in the court that entered the judgment.
4. The clerk dockets the satisfaction on Case.net, marking the judgment as satisfied.

If you received partial payments over time through wage garnishment or bank garnishment, the satisfaction is filed only after the full balance is collected — including post-judgment interest accrued under RSMo § 408.040.

Partial Satisfaction vs. Full Satisfaction

If the debtor pays part of the judgment and you agree to accept a reduced amount as full settlement, document the agreement and file a full satisfaction once the agreed amount is paid. A partial satisfaction records a payment that does not release the remaining balance.

Any partial satisfaction should state clearly what amount was accepted and whether the creditor releases the remaining balance. Ambiguous filings create problems if the debtor later claims the full debt was settled.

What If You Disagree That the Judgment Is Satisfied?

Sometimes a debtor claims full payment, but the creditor's records show an outstanding balance — often because the debtor forgot about accrued post-judgment interest under RSMo § 408.040 (currently 9% per annum for non-tort judgments) or didn't include recoverable court costs.

If you receive a demand to file satisfaction and believe the judgment isn't fully paid, respond in writing within the 50-day period explaining the remaining balance. Document every payment received, the interest calculation, and any costs still owed. If the debtor disputes your math, the court can hold a hearing to determine the correct payoff amount. The court decides whether the judgment has been satisfied; an unpaid balance is not automatically erased by a demand or by the passage of 50 days.

Protecting Yourself as a Creditor

The simplest way to avoid the penalty: file the satisfaction within a week of receiving full payment. Don't wait for the debtor's demand letter. Keep a running ledger of payments and interest so you always know the exact payoff figure.
