If a person sues you in California small claims court and you believe they actually owe you money, you fight back by filing California Judicial Council Form SC-120, the Defendant’s Claim and ORDER to Go to Small Claims Court. You file SC-120 in the same case, on the same trial date, so the judge can decide both claims at once and you avoid starting a separate lawsuit.
You must serve SC-120 on the plaintiff at least 5 days before trial if you both live in the same county, or at least 15 days before trial if you live in different counties, under California Code of Civil Procedure § 116.360. Miss that window and the judge can postpone the trial, refuse to hear your claim, or strike it entirely. According to the Judicial Council of California 2024 Court Statistics Report, California courts processed over 175,000 small claims filings last fiscal year, and a meaningful share involved defendant counterclaims under SC-120.

What Form SC-120 Actually Is
Form SC-120 is the official Judicial Council form a defendant uses to file a claim back against the plaintiff in an active California small claims case. The form is sometimes called a “defendant’s claim,” a “cross-claim,” or a “counterclaim,” but the California Courts Self-Help Center uses the phrase Defendant’s Claim and ORDER. You attach SC-120 to the existing case the plaintiff started with Form SC-100, so both claims share one case number and one trial date.
The plain-English idea is simple. The plaintiff says you owe them money. You say, no, you actually owe me money for a related or unrelated reason. Instead of filing a brand-new lawsuit and waiting months, you piggyback your claim onto the case already on the calendar.
The consequence of not filing SC-120 is steep. If your claim arises out of the same transaction or occurrence — what lawyers call a compulsory counterclaim under CCP § 426.30 — and you skip the filing, you may lose the right to sue on it later. That permanent loss is called claim preclusion, and it is harsh.
A real-world mini-scenario shows the stakes. Maria, a freelance graphic designer in Sacramento, gets sued by a former client for $4,000 in alleged refund money. Maria believes the client still owes her $3,200 in unpaid invoices, so she files SC-120 and asks the judge to net the two amounts. If Maria ignores SC-120 and only defends, she wins the defense but walks away with nothing — and may be barred from suing for the $3,200 later.
A common misconception is that SC-120 is only for related disputes. It is not. California allows defendants to bring almost any money claim against the plaintiff in SC-120, related or unrelated, as long as it fits within the small claims dollar limits described in the California Courts small claims overview.
Who Can File SC-120 and the Dollar Limits
Any defendant named in a California small claims case can file SC-120, whether the defendant is an individual, a sole proprietor, a corporation, a limited liability company, or a partnership. The right to file is set by CCP § 116.360, and the small claims jurisdictional limits are set by CCP § 116.220 as amended by SB 71 (2023).
The plain-English breakdown of the limits is short. Individuals can sue for up to $12,500 per claim. Entities such as corporations, LLCs, and partnerships can sue for up to $6,250 per claim. A person can file no more than two claims per calendar year that exceed $2,500, statewide, under CCP § 116.231.
The consequence of overshooting the limit is automatic. If your counterclaim exceeds $12,500, the judge will not let you collect the excess in small claims; you must waive the overage or move the case to civil court using Form SC-120A and a transfer request. Waiving overage is permanent, so think carefully before you do it.
A common misconception is that the plaintiff’s dollar limit caps your counterclaim. It does not. Your SC-120 has its own limit based on your status (individual or entity), and it is separate from the plaintiff’s claim amount.
Individual Defendant Limits
A natural person — a human being — can claim up to $12,500 per SC-120 in California small claims court. This is the highest small claims limit in the United States, raised from $10,000 by SB 71 effective January 1, 2024, and confirmed by the Judicial Council legislative analysis. The reason the legislature raised the limit was to give regular Californians access to fast, lawyer-free dispute resolution at a time when repair, rent, and medical costs have all climbed.
The consequence of being an individual is favorable here: you get the higher cap. The consequence of waiving part of your claim to fit the cap, however, is that the waived portion is gone forever, even if you later discover the loss was bigger than you thought.
Entity Defendant Limits
A corporation, LLC, partnership, or other legal entity is capped at $6,250 per SC-120. The lower limit exists because the legislature views small claims as a people’s court rather than a forum for business-to-business litigation, as discussed in the California Courts small claims FAQ.
A common misconception is that a sole proprietorship counts as an entity. It does not. The California Courts guide for businesses explains that a sole proprietor sues and is sued as a person, so a sole proprietor uses the $12,500 individual cap.
Step-by-Step Walkthrough of Every Box on SC-120
Below is a line-by-line walkthrough of every numbered section on the current SC-120, using the official form layout from the Judicial Council fillable PDF. Fill out the form in black ink or type it; courts reject pencil and faint ink.
Caption and Case Number
The top-left caption asks for the Superior Court of California, County of ____. Enter the same county and branch listed on the plaintiff’s SC-100 — never a different county. The top-right box asks for the Case Number and Case Name, which you copy verbatim from the plaintiff’s papers.
The consequence of using the wrong county is fatal: the clerk will reject the filing, and you may miss your service deadline while you scramble to refile. A real example: David, a Long Beach mechanic, copied the Los Angeles Stanley Mosk civil courthouse on his SC-120 instead of the Long Beach small claims branch where the SC-100 was filed; the clerk bounced the form, and David lost two precious days.
Section 1 – The Defendant (You) Claims That
Section 1 lists you, the person filing SC-120. Write your full legal name, your street address, your city, your ZIP code, and a daytime phone number. If you operate as a doing-business-as, list the DBA on the second line and attach SC-120A to add additional plaintiffs in the counterclaim.
The consequence of mismatched names is a void judgment. If the SC-100 names you as Robert Smith but you sign SC-120 as Bob Smith, the court may treat them as different people, and you cannot collect on the judgment under CCP § 116.820.
A common misconception is that you can list a P.O. Box. You cannot — California requires a physical street address for service of court papers, per California Rules of Court, Rule 2.111.
Section 2 – The Plaintiff (You Are Suing) Is
Section 2 lists the plaintiff of the original case, who is now also the defendant in your counterclaim. Copy the plaintiff’s name and address exactly as written on SC-100, including business suffixes such as Inc., LLC, or L.P.
The consequence of dropping the suffix is that you may sue the wrong legal entity. Suing Acme Plumbing instead of Acme Plumbing, Inc. can result in a judgment against a non-existent entity, which you cannot collect on. The California Secretary of State Business Search is the right place to confirm an entity’s exact legal name.
Section 3 – Amount and Reason
Section 3 has two parts: the amount you are claiming (in dollars) and the reason for the claim (a short narrative). Write the amount in numerals (for example, $3,750). The narrative must say why the plaintiff owes you money and when the dispute happened.
The plain-English rule is to use one or two sentences, no legalese. The consequence of vague language — for example, “plaintiff was unfair” — is dismissal under CCP § 116.310, which requires a specific factual basis.
A real example helps. Priya, a tenant in Oakland, wrote: “On March 14, 2026, plaintiff-landlord wrongfully kept my $2,800 security deposit and refused to return it within 21 days as required by Civil Code § 1950.5.” That language is specific, dated, and tied to a statute.
Section 4 – Why Are You Filing in This Courthouse
Section 4 asks you to check the box explaining venue. The five options track CCP § 116.370: defendant lives or does business in this county; the contract was signed or performed here; the injury or damage happened here; the buyer signed a retail-installment account here; or a real-estate transaction occurred here. Pick one and only one.
The consequence of picking the wrong venue is transfer or dismissal. A common misconception is that you can use the same venue the plaintiff used — sometimes you can, but you must independently match one of the five statutory grounds.
Section 5 – Have You Asked the Plaintiff for Payment
Section 5 asks whether you demanded payment from the plaintiff before filing. Check yes or no. If no, you must briefly explain why not (for example, “the plaintiff’s attorney refused to communicate with me”).
The plain-English consequence of skipping the demand is judicial frustration. Judges in California small claims expect parties to attempt resolution first under the philosophy of CCP § 116.120, and an unexplained no can hurt your credibility at trial.
Section 6 – Understanding About Small Claims Court
Section 6 contains a list of acknowledgments — that you understand you cannot bring a lawyer to trial under CCP § 116.530, that you waive a jury, that the plaintiff can appeal but you generally cannot if you are the original defendant who filed a counterclaim, and that you must appear at trial.
The consequence of not reading these acknowledgments is real. Defendants sometimes show up with a lawyer and are turned away at the courtroom door, losing both their original defense and their SC-120.
Section 7 – Signature and Declaration
Section 7 is the signature block. You sign under penalty of perjury per CCP § 2015.5, date the form, and print your name. An unsigned SC-120 is not valid and the clerk will reject it.
A common misconception is that an electronic signature is never valid. It can be valid if the county participates in California’s e-filing program, but rules vary by county, so check your local court website first.
Order to Go to Court (Bottom of Form)
The bottom of SC-120 is the Order portion that the clerk completes. The clerk inserts the trial date, time, courtroom, and address. You do not fill this in. Do not write in this section, or the clerk may reject the form.
Three Real-World Scenarios
The three scenarios below show how SC-120 plays out for the most common California disputes, drawn from the California Courts self-help library.
Scenario 1 – Security Deposit Dispute
| What the Defendant Does | What Happens Next |
|---|---|
| Tenant Priya is sued by her ex-landlord for $1,500 in alleged carpet damage | Priya files SC-120 demanding $2,800 deposit plus statutory damages under Civil Code § 1950.5 |
| Priya serves SC-120 by certified mail 16 days before trial | Service is timely under CCP § 116.340, and the court mails proof of receipt |
| Priya brings move-in photos, the lease, and bank records to trial | Judge nets the claims, awards Priya $3,400 net, and enters judgment that day |
Scenario 2 – Auto Repair Gone Wrong
| Step the Defendant Takes | Resulting Consequence |
|---|---|
| Mechanic David is sued by customer for $5,200 in engine damage | David files SC-120 for $1,800 in unpaid labor on the same vehicle |
| David serves the SC-120 only 3 days before trial | Court continues the trial 30 days under CCP § 116.330 because of late service |
| David brings the work order, photos, and a Bureau of Automotive Repair printout | Judge awards customer $5,200, awards David $1,800, customer collects net $3,400 |
Scenario 3 – Unpaid Contractor Invoice
| Action by Contractor-Defendant | Outcome in Court |
|---|---|
| Homeowner sues contractor Lila for $9,000 in alleged defective work | Lila files SC-120 for $7,500 in unpaid final-draw invoices |
| Lila confirms her contractor’s license is active on the CSLB website | Court finds Lila is licensed under Business & Professions Code § 7031, claim allowed |
| Both parties testify and submit photos and the signed contract | Judge awards homeowner $4,000, Lila $7,500, Lila wins $3,500 net |
Filing, Fees, and Service of Process
Filing SC-120 has three steps: file, pay, and serve. Each step has a distinct deadline and a distinct consequence for missing it, and the rules are spread across CCP § 116.230, CCP § 116.340, and the California Rules of Court Title 3, Division 8.
Filing Fees
Filing fees for SC-120 mirror the plaintiff’s fees and are set by CCP § 116.230. Claims of $1,500 or less cost $30. Claims between $1,501 and $5,000 cost $50. Claims between $5,001 and $12,500 cost $75. Frequent filers — those who filed more than 12 small claims in California in the prior 12 months — pay $100 regardless of amount.
The consequence of nonpayment is no filing. The clerk will not accept SC-120 without the fee or a granted fee waiver. You can request a waiver using Form FW-001 if your income is below 125% of the federal poverty line or you receive public benefits.
Service Deadlines
You must personally serve, or mail by certified mail with return receipt, a copy of the filed SC-120 on the plaintiff. If you both reside in the same county, service must be complete at least 5 days before trial. If you reside in different counties, service must be complete at least 15 days before trial, per CCP § 116.340(b).
The consequence of late service is severe. The judge will continue the trial under CCP § 116.330(b) and may shift continuance costs to you. A real example: Marcus, a Riverside contractor, served his SC-120 four days before trial; the judge continued the case six weeks and ordered Marcus to pay the plaintiff’s $250 lost-wage costs.
Proof of Service
You file Form SC-104, the Proof of Service, after your server delivers SC-120. The server must be 18 or older and not a party to the case. You cannot serve SC-120 yourself.
A common misconception is that text or email service is allowed. It is not, unless the plaintiff has agreed to electronic service in writing under CCP § 1010.6.
Comparing SC-120 to Related Small Claims Forms
| Form | Who Uses It | Purpose |
|---|---|---|
| SC-100 | Plaintiff | Starts a small claims case |
| SC-120 | Defendant | Files a counterclaim against plaintiff |
| SC-120A | Defendant | Adds extra parties to the counterclaim |
| SC-104 | Either party | Proof of service of court papers |
| SC-150 | Either party | Request to postpone the trial |
Knowing which form does what avoids costly mix-ups. A defendant who files SC-100 instead of SC-120 has technically opened a new lawsuit and paid an unnecessary fee, and the clerk may not catch the error before trial.
Mistakes to Avoid
Below are the most common SC-120 errors and the negative outcomes they produce. The list draws on data from the Judicial Council 2024 Court Statistics Report and the California Courts self-help knowledge base.
- Filing in the wrong county. The clerk will reject SC-120 if the county does not match the SC-100, costing days you cannot afford.
- Missing the 5-day or 15-day service deadline. The judge will continue the trial and may order you to pay the plaintiff’s costs.
- Serving the plaintiff yourself. Self-service voids the service, and your counterclaim will not be heard.
- Listing a P.O. Box instead of a street address. The clerk will reject the form because court papers cannot be served on a P.O. Box.
- Exceeding the $12,500 or $6,250 cap without waiving overage. The judge will refuse to award anything over the cap unless you formally waive.
- Suing the wrong legal entity. A judgment against a non-existent corporation is uncollectible.
- Vague claim language. A narrative like “plaintiff cheated me” fails the specificity requirement of CCP § 116.310 and may be stricken.
- Bringing a lawyer to trial. CCP § 116.530 bars represented appearance, and the judge will not let your attorney speak.
- Skipping pre-suit demand without explanation. Judges expect a demand and may rule against you for failing to attempt resolution.
- Forgetting to sign Section 7. An unsigned SC-120 is invalid, and the clerk will return it.
Do’s and Don’ts
These quick-reference rules are drawn from the California Courts SC-120 instructions.
Do’s
- Do file SC-120 as soon as you receive the SC-100, because the earlier you file, the easier service becomes.
- Do keep three copies — one for the court, one for the plaintiff, one for yourself — to avoid last-minute copying.
- Do request a fee waiver on FW-001 if you qualify, because waivers are routinely granted to low-income filers.
- Do organize evidence chronologically, since judges hear cases quickly and clarity wins.
- Do visit the small claims advisor in your county for free, neutral help under CCP § 116.940.
Don’ts
- Don’t file SC-120 in a different county than the plaintiff’s case, because the clerk will reject it.
- Don’t serve the form by text, email, or social media unless the plaintiff agrees in writing.
- Don’t exaggerate damages, since perjury under CCP § 2015.5 is a crime.
- Don’t miss trial; failure to appear results in dismissal of your counterclaim with prejudice.
- Don’t bring a lawyer to argue the case, because California law forbids it in small claims.
Pros and Cons of Filing SC-120
| Pros | Cons |
|---|---|
| Resolves both claims in one trial, saving time and filing fees | Limits you to $12,500 (individual) or $6,250 (entity) |
| No attorneys allowed, so legal costs stay near zero | You give up jury trial and most appeal rights |
| Fast resolution, often within 30–70 days of filing | Tight 5-day or 15-day service deadline |
| Same judge hears both sides, leading to fair netting | You must appear in person, which can mean lost wages |
| Filing fee is low, $30–$100 | Counterclaim must be against the plaintiff, not a third party |
Each of these tradeoffs has a why behind it. The no-lawyer rule reflects the legislature’s goal of keeping small claims accessible to ordinary people, as the California Courts overview explains, while the dollar cap reflects the court’s limited equitable powers.
Recap of Key Court Rulings
California appellate courts have shaped how SC-120 is read in practice. In Pitzen v. Superior Court, 120 Cal.App.4th 1374 (2004), the Court of Appeal held that a small claims judgment is binding on the parties and bars later relitigation of the same claim, reinforcing the use it or lose it nature of SC-120. In ERA-Engle-Lawhon Realty, Inc. v. Brown, 199 Cal.App.3d 1080 (1988), the court held that a defendant who fails to assert a related counterclaim in small claims may be barred from raising it later in superior court.
The plain-English consequence is that filing SC-120 is sometimes not optional. If your claim arises from the same facts as the plaintiff’s claim, file it now or lose it forever, the same warning you find in California Civil Jury Instructions (CACI) 5003.
A common misconception is that small claims rulings have no precedential value. They lack precedential value for other cases, but they have full res judicata effect between the parties, as confirmed in Sanderson v. Niemann, 17 Cal.2d 563 (1941).
Key Entities and Their Roles
The SC-120 process pulls in several California institutions. The Judicial Council of California drafts and updates the form. The California Department of Consumer Affairs publishes the Small Claims Handbook. The California Secretary of State confirms the legal names of business plaintiffs. The Bureau of Automotive Repair and the Contractors State License Board supply records used as trial evidence in industry-specific disputes.
Each plays a why role. The Judicial Council ensures statewide uniformity. The DCA provides plain-English education. The Secretary of State prevents misnamed-entity errors. Industry boards supply licensing and complaint records that judges find persuasive.
County-Level Filing Nuances
California’s 58 counties run their own small claims clerks under the umbrella of the California Superior Courts, so local rules vary. Los Angeles County allows e-filing through LACourtConnect, while smaller counties such as Modoc and Alpine still require paper filings. San Francisco runs walk-in small claims advisor clinics under San Francisco Superior Court Local Rule 27.
The consequence of ignoring local rules is rejection. A real example: Tomas, a San Diego software contractor, tried to e-file SC-120 in San Diego County, only to learn that small claims is paper-only there; he had to drive to the Hall of Justice the next day to file in person, nearly missing the 15-day service window.
A common misconception is that the form is the same statewide and the procedure is the same statewide. The form is identical because the Judicial Council mandates it, but local procedure — e-filing, drop-box hours, advisor availability — varies, so always check your county’s website first.
FAQs
Can I file SC-120 after my small claims trial date?
No. SC-120 must be filed and served before trial under CCP § 116.360; filing after trial is barred, and you may forfeit the claim entirely under res judicata principles confirmed in Pitzen v. Superior Court.
Can I bring a lawyer to argue my SC-120 at trial?
No. California Code of Civil Procedure § 116.530 forbids attorney representation at small claims trial, although a lawyer may help you prepare paperwork beforehand and advise you on strategy off the record.
Can I file SC-120 if my counterclaim is more than $12,500?
Yes. You may file, but you must waive any amount above $12,500 for individuals or $6,250 for entities; alternatively, you can ask to transfer the entire case to limited civil court under CCP § 116.390.
Can I serve SC-120 by regular first-class mail?
No. Service must be by personal delivery, certified mail with return receipt, or any other method allowed by CCP § 116.340; regular mail does not satisfy the statute.
Can I appeal if I lose on my SC-120?
No. A defendant who files SC-120 generally cannot appeal a loss on the original plaintiff’s claim, but the plaintiff on the counterclaim — that is, you — may appeal a loss on your own SC-120 claim under CCP § 116.710.
Can I file SC-120 against a non-party who is not the plaintiff?
No. SC-120 is limited to claims against the plaintiff named in the SC-100; to add parties, file a separate small claims action or use Form SC-120A for additional defendants in the counterclaim only.
Can I dismiss my SC-120 before trial?
Yes. You may dismiss the counterclaim voluntarily by filing Form CIV-110 any time before judgment, although filing fees are generally non-refundable under California Government Code § 70617.
Can I count toward the $12,500 cap by combining several invoices?
Yes. You may combine related invoices into one claim, but the total amount remains capped at $12,500 for individuals or $6,250 for entities, and any excess is permanently waived once you file.
Can I file SC-120 if I am a sole proprietor?
Yes. Sole proprietors are individuals under California law, so you use the higher $12,500 cap and follow the same SC-120 process described in the California Courts business guide.
Can I postpone my trial after filing SC-120?
Yes. Either party may file Form SC-150 at least 10 days before trial and pay a $10 fee under CCP § 116.570; the judge may grant or deny the request based on good cause.
Can I recover my filing fees if I win on SC-120?
Yes. Under CCP § 1032, the prevailing party recovers ordinary court costs, including the SC-120 filing fee and service-of-process costs, as part of the judgment.
Can I e-file SC-120 in every California county?
No. Only some counties — including Los Angeles, Orange, San Francisco, and Riverside — accept e-filing for small claims; check your county’s Find My Court page to confirm whether paper filing is required.
