Yes — California Form MC-051 is the official Judicial Council form titled Acknowledgment of Satisfaction of Judgment, and you fill it out by identifying the case, marking whether the satisfaction is full, partial, or matured installment, listing every judgment creditor and debtor, signing it in front of a notary public, and then filing the original with the clerk of the court that entered the judgment. You can download the current version directly from the California Courts MC-051 page, and the rules that govern it appear in Code of Civil Procedure sections 724.010–724.260.
A judgment creditor who refuses or forgets to file this form after being paid can be hit with a $100 statutory penalty plus all actual damages under CCP § 724.050, and the debtor can sue in small claims court to force compliance. According to the Judicial Council 2024 Court Statistics Report, more than 1.1 million civil money judgments were entered in California trial courts in fiscal year 2022–2023, and tens of thousands of those judgments are satisfied every year using MC-051.

What Form MC-051 Is and Why It Exists
Form MC-051 is the Acknowledgment of Satisfaction of Judgment, a one-page Judicial Council form approved for mandatory use under California Rules of Court, rule 1.31. The form tells the court, the county recorder, and the credit bureaus that a money judgment has been paid in full, paid in part, or has matured through completed installments. Without this filing, the judgment continues to appear as an outstanding debt for up to ten years under CCP § 683.020, and it can be renewed for another ten years.
The form exists to protect the judgment debtor. A debtor who has paid every penny still suffers credit damage, wage garnishment risk, and abstract-of-judgment liens on real estate until MC-051 is filed. The Legislature created the penalty structure in CCP § 724.050 precisely because creditors used to drag their feet and ruin debtors’ credit even after collecting.
Federal law plays only a background role here. The Fair Credit Reporting Act, 15 U.S.C. § 1681 requires consumer reporting agencies to update tradelines once a satisfaction is recorded, and the Fair Debt Collection Practices Act bars collectors from continuing to demand a paid judgment. California layers MC-051 on top of those federal rules to give the debtor a clean, recordable document.
Plain-English Purpose
In plain English, MC-051 is a receipt the winner of a lawsuit signs to say, “I got my money, the case is over.” The clerk stamps it, files it, and the case file shows the judgment as satisfied. Anyone who later pulls the case — a landlord, a lender, an employer — sees the satisfaction stamp and treats the debt as resolved.
The consequence of skipping the receipt is severe. The debtor’s credit report keeps showing an unpaid judgment, and any title company running a lien search on real property will refuse to close escrow.
A real-world example: Carmen Reyes paid off a $7,400 small claims judgment in March 2025, but the creditor never filed MC-051. When Carmen tried to refinance her Fresno home in July, the title company found the abstract of judgment and held up the loan for six weeks. Carmen sued the creditor in small claims court and recovered the $100 penalty plus $1,800 in lost-rate-lock damages.
A common misconception is that paying the creditor automatically clears the court record. It does not. The court file stays open until the clerk receives a signed, notarized MC-051 or a court-issued Acknowledgment under CCP § 724.050(d).
Statutory Framework
The full statutory framework lives in Article 1 of Chapter 7 of Title 9 of Part 2 of the CCP. Section 724.010 defines what counts as satisfaction. Section 724.030 requires the creditor to file the acknowledgment immediately after full satisfaction. Section 724.050 lets the debtor send a written demand and triggers the $100 penalty plus actual damages if the creditor ignores the demand for fifteen days.
The consequence of ignoring a 724.050 demand is that the debtor can sue and add attorney’s fees if the creditor’s failure was willful. The California Court of Appeal confirmed this in Lucky United Properties Investment, Inc. v. Lee (2010) 185 Cal.App.4th 125, where the court awarded both the statutory penalty and additional damages for a delayed acknowledgment.
A common misconception is that the $100 penalty is the cap on liability. It is only the floor. Actual damages, including lost loan opportunities, higher interest rates, and emotional distress in some cases, stack on top of the statutory penalty.
When You Must File MC-051
You must file MC-051 in three situations: a fully paid money judgment, a partially paid money judgment when the debtor demands acknowledgment of the partial payment, and a judgment payable in installments where every installment has matured. The triggering event in each case is different, and the consequence of missing the trigger is the same — exposure to the CCP § 724.050 penalty.
The creditor has an affirmative duty to file immediately after full satisfaction under CCP § 724.030. “Immediately” is not defined by a specific number of days, but California courts read it together with the fifteen-day demand window in section 724.050. As a practical matter, file within fifteen days of receiving the final payment to avoid liability.
A real-world example involves David Nguyen, a contractor who collected a $32,000 unlimited civil judgment in Santa Clara County. David received the wire transfer on April 2, 2026, but did not file MC-051 until June 12, 2026. The debtor sent a written demand on April 25, and David’s seventy-day delay cost him $100 in statutory penalty plus $4,200 in proven actual damages from a delayed business loan.
Full Satisfaction Trigger
Full satisfaction occurs when the debtor pays the entire principal, all accrued interest at the 10% post-judgment rate under CCP § 685.010, all awarded costs, and any attorney’s fees added under CCP § 685.040. The moment the last dollar lands, the creditor’s clock starts.
The consequence of misjudging the trigger is that the creditor either files too early — leaving accrued interest unpaid — or files too late and incurs penalties. Use a written payoff statement and a dated receipt to lock in the trigger date.
A common misconception is that a wire transfer “in transit” counts as paid. It does not. Payment is complete only when the funds clear and are available to the creditor.
Partial Satisfaction Trigger
Partial satisfaction is filed when the debtor makes a substantial payment but the judgment is not fully paid. Under CCP § 724.110, the debtor can demand a partial acknowledgment, and the creditor must file within fifteen days of the demand. The form has a specific checkbox for partial satisfaction and a line for the dollar amount received.
The consequence of refusing to file partial satisfaction is the same $100 penalty plus damages. Partial satisfaction also matters when the debtor sells real estate and needs the abstract of judgment partially released.
A real-world example: Priya Shah owed $50,000 on a Los Angeles County limited civil judgment. She paid $30,000 in February 2026 and demanded a partial acknowledgment. The creditor filed MC-051 with the partial box checked and “$30,000.00” written on the partial-amount line, allowing Priya to refinance her duplex while still owing the $20,000 balance.
Matured Installment Trigger
Matured installment judgments are common in family support cases and structured settlements. Once every scheduled installment has come due — whether or not actually paid — the creditor must file MC-051 with the matured-installment box checked under CCP § 724.250.
The consequence of skipping this filing is that the judgment appears unenforceable on its face but remains on the docket, confusing future creditors and title examiners. The matured-installment acknowledgment cleans up the record without waiving the right to collect arrears.
A common misconception is that “matured” means “paid.” It does not. Matured simply means the time for each installment has passed. The creditor can still pursue arrears with a writ of execution after filing the matured-installment MC-051.
Line-by-Line Walkthrough of Form MC-051
The current MC-051 has eight numbered sections plus a notary acknowledgment block. Each section has consequences if filled in incorrectly, and the clerk will reject the form for any of the seven defects listed in Government Code § 27201 when the document is also recorded.
You can fill the form on a typewriter, in legible black ink, or — most commonly today — using the fillable PDF on the California Courts website. The fillable PDF auto-formats dollar amounts and prevents most clerk-rejection errors.
A real-world example: Marcus O’Brien, a self-represented small claims winner in San Diego, downloaded the fillable PDF, completed it in fifteen minutes, signed before a UPS Store notary for $15, and mailed the original to the clerk with a self-addressed stamped envelope. He had a file-stamped copy back in eight days.
Caption and Attorney/Party Information
The caption box at the top requires the name, State Bar number (if any), address, telephone, fax, and email of the attorney or party without attorney. The judgment creditor — not the debtor — fills this in, even if the debtor drafted the form. The court name and branch must match the court that entered the judgment exactly.
The consequence of a mismatched court name is rejection by the clerk. If the judgment came from the Stanley Mosk Courthouse, Central District, do not write “Los Angeles Superior Court” alone — list the branch.
A common misconception is that the debtor’s lawyer can sign in this box. The lawyer cannot. Only the creditor or the creditor’s attorney of record may execute the acknowledgment under CCP § 724.060.
Item 1 — Type of Satisfaction
Item 1 has three checkboxes: Full, Partial, and Matured Installment. Check exactly one. Checking two boxes guarantees rejection or, worse, ambiguity that the debtor’s title company will treat as no satisfaction at all.
The consequence of checking “Full” when only partial payment was received is potential fraud exposure. The creditor has signed under penalty of perjury that the entire judgment is paid, which gives the debtor leverage to wipe out any remaining balance.
A real-world example: Tanya Goldberg, a creditor in Alameda County, mistakenly checked “Full” on a $15,000 judgment after receiving only $9,000. The debtor recorded the form, sold the house, and the court refused to let Tanya un-ring the bell. She lost the remaining $6,000.
Item 2 — Full Name and Address of Judgment Creditor
Item 2 requires the full legal name and current mailing address of every judgment creditor. If the judgment lists “Acme Plumbing, Inc.,” do not write “Acme Plumbing.” A name mismatch will block the county recorder from indexing the satisfaction against the original abstract.
The consequence of a name mismatch is a clouded title that may take a quiet-title action to clear. Use the exact name from the original judgment, and if the creditor has changed names since (marriage, merger, DBA), add an “also known as” line.
A common misconception is that the creditor’s current address is enough. It is not — the form needs the address where the creditor wants future court notices sent.
Item 3 — Full Name and Address of Assignee of Record
Item 3 applies only when the judgment has been assigned under CCP § 673. If the original creditor sold the judgment to a debt buyer, the assignee of record signs MC-051, not the original creditor. Leave the box blank if there has been no assignment.
The consequence of having the wrong party sign is total invalidity. A satisfaction signed by a non-assignee is void, and the debtor must redo the entire process.
A real-world example: Ben Carter paid $4,000 to settle a judgment that had been assigned three times. He needed signatures only from the third assignee — Midland Funding LLC — and the clerk rejected an earlier draft signed by the original creditor’s attorney.
Item 4 — Full Name and Address of Judgment Debtor
Item 4 lists every judgment debtor by full legal name and last known address. If there are multiple debtors and only some have paid, see item 5 for the carve-out box.
The consequence of leaving a debtor off the form is that that debtor’s credit and title remain encumbered. Each debtor needs to appear by name even when joint and several liability applies.
A common misconception is that paying off one of two co-debtors satisfies the entire judgment. It does not unless the creditor expressly checks “Full” satisfaction for both.
Item 5 — Judgment Information
Item 5 captures four data points: the date the judgment was entered, the book and page or document number where any abstract or notice of judgment lien was recorded, the county of recording, and — if a federal tax-lien-style notice was recorded with the Secretary of State — the file number and date.
The consequence of an incorrect recording reference is that the county recorder cannot index the satisfaction against the abstract, leaving the lien on title. Always pull the original recorded abstract before filling in this section.
A real-world example: Hannah Lopez found her recorded abstract in the Los Angeles County Registrar-Recorder online index, copied document number 20230123456 into Item 5b, and her satisfaction recorded cleanly the next business day.
Item 6 — Renewed Judgments
Item 6 asks whether the judgment has been renewed under CCP § 683.110 and, if so, the date of each renewal. Renewals extend the enforceability for another ten years and have their own recording footprint.
The consequence of forgetting a renewal is a half-cleared record. The original abstract gets satisfied, but the renewal abstract still sits on title.
A common misconception is that renewals are rare. They are not — in long-running judgments, especially those secured by real property, creditors routinely renew at year nine.
Item 7 — Partial Satisfaction Amount
Item 7 is mandatory only when Item 1’s “Partial” box is checked. Write the exact dollar amount received, in figures, and spell out the source of the payment if it came from a third-party guarantor.
The consequence of leaving Item 7 blank on a partial filing is rejection or, worse, a recorded document that does not specify how much credit the debtor receives.
A real-world example: Kenji Watanabe paid $12,500 toward a $40,000 judgment, and the creditor wrote “$12,500.00” in Item 7. The county recorder indexed a partial release, and Kenji’s title insurer accepted the partial as a $12,500 reduction in the lien.
Item 8 — Signature and Notary
Item 8 requires the signature of the judgment creditor, assignee of record, or the attorney of record. The signature must be acknowledged before a California notary public under Civil Code § 1185 if the document will be recorded with the county recorder.
The consequence of skipping notarization on a recordable filing is rejection by the recorder under Government Code § 27287. The court clerk will accept an unnotarized form, but the recorder will not, so always notarize when an abstract was recorded.
A common misconception is that any out-of-state notary works. A notary from another state works only if the notarization complies with California’s acknowledgment certificate format under Civil Code § 1189.
Three Real-World Scenarios
These three scenarios show the most common ways MC-051 plays out in California courts. Each scenario highlights the step taken and the result that follows so you can see the cause-and-effect chain.
Scenario 1: Full Satisfaction in Small Claims
| Step Taken | Result That Follows |
|---|---|
| Debtor pays $5,000 in full to creditor on April 1, 2026 | Creditor’s 15-day clock under CCP § 724.030 begins |
| Creditor signs MC-051 before notary on April 3, 2026 | Form is ready for filing and recording |
| Creditor files original with small claims clerk on April 5 | Court docket shows judgment as fully satisfied |
| Creditor records certified copy with county recorder on April 8 | Abstract of judgment lien is released |
| Debtor’s credit report updates within 30–60 days | FICO score recovers up to 40 points |
Scenario 2: Partial Satisfaction with Real Property Sale
| Step Taken | Result That Follows |
|---|---|
| Debtor pays $30,000 of $50,000 judgment to facilitate home sale | Partial satisfaction trigger under CCP § 724.110 |
| Debtor sends written demand for partial acknowledgment | 15-day creditor response window opens |
| Creditor files MC-051 with “Partial” box and “$30,000” in Item 7 | Title company accepts $30,000 lien reduction |
| Escrow closes, remaining $20,000 lien follows debtor | Creditor retains right to enforce balance |
| Creditor records writ of execution on bank account later | Remaining $20,000 collected without re-litigation |
Scenario 3: Matured Installment Judgment
| Step Taken | Result That Follows |
|---|---|
| Five-year installment judgment finishes scheduled payments | Maturity trigger under CCP § 724.250 |
| Creditor files MC-051 with “Matured Installment” box checked | Court docket reflects matured status |
| Creditor preserves arrears claim by separate writ | Right to collect unpaid installments survives |
| Debtor’s credit tradeline updates to “satisfied” | New financing becomes available |
| County recorder indexes satisfaction against abstract | Real property title clears |
Filing, Service, and Recording Steps
After signing and notarizing MC-051, three filings may be needed: the original with the clerk of the issuing court, a certified copy with the county recorder in every county where an abstract was recorded, and a copy mailed to the judgment debtor under CCP § 724.060. Skipping any of the three leaves part of the record uncleared.
Court filing fees for MC-051 itself are zero in most counties, but a recording fee of roughly $25 for the first page applies at the county recorder. Check your county’s current fee schedule because the SB 2 Building Homes and Jobs Act surcharge adds $75 per recording in many cases unless the document qualifies for an exemption.
A real-world example: Sofia Martinez won a Sacramento County judgment, recorded the abstract in three counties (Sacramento, Placer, and El Dorado), and had to record certified copies of MC-051 in all three to fully clear title. She used the CIV-100 (Request for Dismissal) only for the underlying complaint, not for satisfaction.
Where to File the Original
The original signed and notarized MC-051 goes to the clerk of the court that entered the judgment. Use the courthouse and department listed on the original judgment, not the county’s central filing window. Many counties now accept e-filing through File & ServeXpress or One Legal.
The consequence of filing in the wrong courthouse is delay. The clerk will return the form for re-filing, and the 15-day window in CCP § 724.050 keeps running.
A common misconception is that the small claims and civil divisions share filing windows. They often do not — small claims matters file in a separate division with its own clerk.
How to Record with the County
Recording requires a certified copy of MC-051 obtained from the court clerk for a per-page fee. Take the certified copy to the county recorder’s office in every county where an abstract of judgment was recorded under CCP § 697.310.
The consequence of recording in the wrong county is that the lien on real property in the correct county survives the satisfaction. Search every county where the debtor owns or has owned real estate.
A real-world example: William Park satisfied a $200,000 judgment but only recorded MC-051 in Orange County. The original abstract had also been recorded in Riverside County, where the debtor owned a vacation home, and that lien stayed on title until William paid the recorder a second time.
Service on the Judgment Debtor
CCP § 724.060 implicitly contemplates that the debtor receives a copy of the satisfaction. Best practice is to mail a conformed copy to the debtor’s last known address with a Proof of Service by Mail (form POS-030) attached.
The consequence of skipping service is that the debtor may dispute receipt and add to a damages claim under section 724.050. Service is cheap insurance.
A common misconception is that filing with the clerk constitutes service on the debtor. It does not — California requires separate notice in most post-judgment contexts.
Mistakes to Avoid
Avoiding these common mistakes prevents rejection, penalties, and re-filing costs. Each mistake comes with a specific negative outcome that has bitten real California litigants.
- Checking two satisfaction boxes — The clerk rejects the form, and you lose days off the 15-day clock.
- Misspelling the creditor’s legal name — The county recorder cannot index the satisfaction, and the lien survives.
- Forgetting to notarize before recording — The recorder bounces the document under Government Code § 27287.
- Skipping the renewal date in Item 6 — The renewal abstract stays on title even after the original is satisfied.
- Letting the assignor sign instead of the assignee — The satisfaction is void, and the debtor must start over.
- Filing only with the court and not the recorder — Real property liens persist for the full ten-year life of the abstract.
- Filing only with the recorder and not the court — The court docket still shows the judgment as unpaid.
- Writing “$0.00” or leaving Item 7 blank on a partial filing — The recorder treats it as no credit at all.
- Using an out-of-state notary with the wrong certificate — California rejects the acknowledgment under Civil Code § 1189.
- Waiting more than 15 days after a written demand — The $100 penalty plus actual damages attach automatically.
Do’s and Don’ts
These guidelines come straight from the California Courts self-help center on satisfying a judgment and the DCBA Small Claims Guide.
Do’s:
- Do download the current version of MC-051 from the Judicial Council site, because outdated forms get rejected.
- Do notarize before signing the filing copy, because the recorder will not accept a missing acknowledgment.
- Do record in every county where an abstract exists, because real property liens are county-specific.
- Do keep a file-stamped copy for at least four years, because credit-bureau disputes can arise long after filing.
- Do use a fillable PDF instead of a handwritten form, because typos cause indexing failures.
Don’ts:
- Don’t sign before receiving cleared funds, because a bounced check leaves you with a satisfied judgment and no money.
- Don’t rely on the debtor’s lawyer to draft the form, because errors are your problem if you sign.
- Don’t forget post-judgment interest at 10%, because partial payments can leave a hidden balance.
- Don’t ignore a written demand letter, because the 15-day clock under CCP § 724.050 is unforgiving.
- Don’t record the original — record a certified copy, because the recorder keeps what you file.
Pros and Cons of Filing MC-051 vs. Court-Ordered Satisfaction
When a creditor refuses to file, the debtor can move the court for an order under CCP § 724.050(d). That route has its own trade-offs.
Pros of voluntary MC-051 filing:
- Faster — typically 1–3 weeks versus 60–90 days for a motion.
- Cheaper — no motion fee, no hearing, no attorney time.
- Less adversarial — preserves any business relationship between the parties.
- Cleaner record — a single document rather than a court order plus minute entry.
- Avoids penalties — the creditor sidesteps the $100 plus damages exposure.
Cons of voluntary filing:
- Requires creditor cooperation, which sometimes never comes.
- Leaves enforcement gaps if Items 5 or 6 are wrong.
- No judicial oversight, so errors are not caught until recording fails.
- Notary fees and recording fees fall on the creditor or are negotiated.
- Cannot waive the creditor’s right to pursue separately recorded abstracts unless every county is addressed.
Related Forms You May Also Need
MC-051 rarely operates alone. The following Judicial Council forms commonly accompany or follow it.
| Form | Purpose | Where Found |
|---|---|---|
| EJ-100 | Acknowledgment of Satisfaction (enforcement-only variant) | Judicial Council |
| MC-012 | Memorandum of Costs After Judgment, Acknowledgment of Credit | Judicial Council |
| SC-220 | Request to Pay Judgment in Installments (small claims) | Judicial Council |
| EJ-001 | Abstract of Judgment — Civil and Small Claims | Judicial Council |
| EJ-130 | Writ of Execution | Judicial Council |
EJ-100 and MC-051 overlap heavily. EJ-100 is the older “Acknowledgment of Satisfaction of Judgment” tied to enforcement, while MC-051 is the broader miscellaneous-form variant. Many counties now accept either, but always check the Local Rules of Court for your county.
Court Rulings That Shape MC-051 Practice
Two appellate decisions drive how California courts interpret the satisfaction-of-judgment statutes. Lucky United Properties Investment, Inc. v. Lee (2010) 185 Cal.App.4th 125 confirms that a debtor who proves willful refusal to file MC-051 may recover both the $100 statutory penalty and additional actual damages, including attorney’s fees in a separate action. The court rejected the creditor’s argument that the $100 was an exclusive remedy.
Jhaveri v. Teitelbaum (2009) 176 Cal.App.4th 740, available through Justia, holds that the demand under CCP § 724.050 must substantially comply with the statute’s content requirements but does not need magic words. A debtor’s letter that clearly demands acknowledgment and references the case number is enough.
Lucky United and Jhaveri together mean that creditors cannot stall, and debtors do not need lawyers to send effective demand letters. Both rulings strengthen the practical leverage MC-051 gives ordinary Californians.
Frequently Asked Questions
Is MC-051 mandatory or optional?
Yes. MC-051 is a Judicial Council form approved for mandatory use under California Rules of Court, rule 1.31, whenever a money judgment is fully or partially satisfied or installments mature.
Do I have to notarize MC-051?
Yes. Notarization is required if the form will be recorded with a county recorder under Government Code § 27287, even though the court clerk will accept an unnotarized version for the case file.
Can the judgment debtor file MC-051 instead of the creditor?
No. Only the judgment creditor, the assignee of record, or the creditor’s attorney of record may sign MC-051; the debtor’s remedy when the creditor refuses is a CCP § 724.050(d) motion.
Is there a filing fee for MC-051 at the court?
No. California courts charge no filing fee for MC-051, although the county recorder typically charges around $25 for the first page plus SB 2 surcharges where applicable.
Does filing MC-051 automatically update my credit report?
No. Credit bureaus update only after the satisfaction is recorded with the county recorder and the data flows through the LexisNexis public-records feed, which usually takes 30 to 60 days.
Can I file MC-051 electronically?
Yes. Most California superior courts allow e-filing through approved vendors like One Legal or File & ServeXpress, and many county recorders accept electronic recording under Government Code § 27391.
Does MC-051 cover post-judgment interest and costs?
Yes. A “Full” satisfaction means principal, accrued 10% interest under CCP § 685.010, awarded costs, and any post-judgment fees added under CCP § 685.040 are all paid in full.
Can I record MC-051 in multiple counties?
Yes. You must record a certified copy in every county where an abstract of judgment was recorded; otherwise the lien on real property in the unrecorded county survives.
Is the $100 penalty under CCP § 724.050 the maximum I can recover?
No. The $100 is a statutory floor; debtors may also recover all actual damages caused by the failure to file, plus attorney’s fees in some willful-refusal cases under Lucky United.
Does MC-051 apply to family law support judgments?
Yes. Matured installment satisfactions for spousal and child support arrears can use MC-051 under CCP § 724.250, although many family courts also use specialized FL-series forms.
Can I revoke an MC-051 filed by mistake?
No. Once filed and recorded, MC-051 is binding; the only remedy is a court motion to set aside the satisfaction for fraud or mutual mistake, which is rarely granted.
How long does the creditor have to file after receiving full payment?
Yes, there is a clear deadline. CCP § 724.030 requires “immediate” filing, and the 15-day window after a written demand under CCP § 724.050 sets the practical outer limit before penalties attach.
