California Form DISC-020 is the Judicial Council’s official “Requests for Admission” form used in civil cases to ask the other party to admit or deny specific facts, the genuineness of documents, or the application of law to facts. You fill it out by entering the case caption, identifying the propounding and responding parties, numbering each request consecutively, and serving it under the rules in California Code of Civil Procedure section 2033.010.
The form looks simple, but small mistakes cause big problems. According to the Judicial Council of California 2023 Court Statistics Report, roughly 1.1 million civil cases are filed each year in California superior courts, and discovery disputes drive a large share of motion practice in those cases.

What Form DISC-020 Is and Why It Matters
Form DISC-020 is the Judicial Council’s optional but widely used template for Requests for Admission in California civil litigation. The form gives parties a structured way to ask the other side to admit the truth of facts, the genuineness of documents, or the application of law to facts under CCP section 2033.010. When a party admits a request, that fact is conclusively established for the case under CCP section 2033.410.
The purpose of the form is to narrow the issues for trial. If a fact is admitted, no one needs to prove it with witnesses or exhibits. This saves court time and lowers legal costs for everyone. Judges favor parties who use admissions to focus the case.
The plain-English idea is simple. You ask the other side, “Admit that you ran the red light at 5th and Main on June 1, 2025.” If they admit it, that issue is closed. If they deny it without good cause and you later prove it at trial, the court can order them to pay your attorney’s fees under CCP section 2033.420.
The consequence of ignoring the form is harsh. If you fail to respond on time, the propounding party can move to have the matters deemed admitted under CCP section 2033.280. A deemed-admitted order can end your case before trial.
A real example helps. Maria, a small business owner sued for breach of contract, ignored a packet of admissions for 45 days. Her opponent moved under section 2033.280, and the court deemed every request admitted, including liability and damages. Maria lost the case on a motion for summary judgment two weeks later.
A common misconception is that DISC-020 is “just paperwork” you can answer casually. It is not. Each response is a sworn statement, and the Wimberly v. Derby Cycle Corp. (1997) 56 Cal.App.4th 618 decision confirms that admissions bind the responding party at trial unless the court allows withdrawal under CCP section 2033.300.
Who Can Use DISC-020 and When
Any party in a California civil case can use Form DISC-020, including plaintiffs, defendants, cross-complainants, and cross-defendants. The form is part of the Judicial Council’s discovery package, alongside DISC-001 (Form Interrogatories—General) and DISC-002 (Special Interrogatories). Federal court litigants do not use this form; they use Federal Rule of Civil Procedure 36 instead.
The timing rules come from CCP section 2033.020. A plaintiff may serve admissions 10 days after the defendant is served with the summons, or after the defendant appears, whichever comes first. A defendant may serve admissions at any time. The last day to serve is generally 30 days before trial under CCP section 2024.020.
The consequence of serving too early is that your requests are void, and the responding party can ignore them. The consequence of serving too late is that the court will not enforce them. Both outcomes waste filing fees and lawyer time.
A real example shows the timing trap. David, a tenant suing his landlord, served DISC-020 only 25 days before trial. The landlord refused to respond, and the court denied David’s motion to compel because the cutoff under section 2024.020 had passed.
A common misconception is that you can extend the cutoff by stipulation alone. You cannot extend it past the statutory limit unless the court signs an order under CCP section 2024.060.
Limited vs. Unlimited Civil Cases
In unlimited civil cases (over $35,000 in controversy), each party may serve up to 35 requests for admission of fact or law per opposing party under CCP section 2033.030. Requests to admit the genuineness of documents are unlimited in number. Going past 35 requires a DISC-005 Declaration for Additional Discovery.
In limited civil cases (under $35,000), the cap is even tighter. Under CCP section 94, each side gets only 35 combined discovery requests across interrogatories, document demands, and admissions, except admissions about document genuineness.
The consequence of ignoring these caps is that the responding party can object and refuse to answer the excess requests. Anita, a plaintiff in a limited civil case, served 50 admissions and got objections to 15 of them, losing key evidence at trial.
Step-by-Step: How to Fill Out DISC-020
The form is two short pages, but every box matters. The current version is dated January 1, 2024, and is available on the California Courts forms website. Use the most recent version, because clerks reject outdated forms.
Caption Block (Top of Page 1)
The top of the form mirrors the caption from your complaint. Enter the attorney or self-represented party’s name, State Bar number (if any), address, phone, fax, email, and the party they represent. Then list the superior court name, branch, street address, mailing address, city and ZIP code, and branch name as shown on your filed complaint.
The plain-English rule is to match the complaint exactly. The consequence of a mismatched caption is rejection at filing or, worse, confusion that delays your case. Carlos, a self-represented plaintiff, used a different court branch name on his form and the clerk rejected the proof of service.
A common misconception is that you must file DISC-020 with the court. You do not. Discovery requests are served on the parties only and are not filed under California Rules of Court, Rule 3.250.
Short Title and Case Number
Below the caption, enter the short title of the case (for example, Smith v. Jones) and the case number assigned by the court. These help the clerk and opposing counsel match the document to the right file.
The consequence of a wrong case number is that opposing counsel may treat the requests as not properly served. Always copy the case number directly from the complaint or a filed document.
Set Number
DISC-020 has a blank for “SET NO.” You enter “ONE” for your first set of admissions to that party, “TWO” for the second, and so on. Each opposing party gets its own numbering sequence.
The consequence of skipping or repeating set numbers is that the responding party can object for ambiguity. Janet, a defense attorney, served “Set Two” without ever serving “Set One,” and the plaintiff successfully moved for a protective order under CCP section 2033.080.
Identifying Propounding and Responding Parties
The form asks you to fill in three lines: the propounding party (the one sending the requests), the responding party (the one who must answer), and the set number. Use the parties’ full legal names as they appear in the caption, not nicknames or abbreviations.
The plain-English rule is to be precise. The consequence of vague party names is an objection on the ground that the request is unclear. If there are multiple defendants, you must serve a separate DISC-020 on each one and identify them by name.
Drafting the Requests Themselves
DISC-020 provides numbered blanks for each request. Each request must be a single, clear statement that asks the other side to admit something specific. Under CCP section 2033.060, each request must be “full and complete in and of itself” and cannot incorporate other documents by reference, except to attach a document for admission of genuineness.
The plain-English rule is one fact per request. The consequence of compound requests is that the responding party can object and refuse to answer. Brian, a plaintiff, wrote, “Admit that you were speeding and ran a red light,” and the defendant objected as compound, killing the request.
A real example of a clean request is: “Admit that on June 1, 2025, you owned the 2022 Toyota Camry, license plate 8XYZ123, involved in the collision.” This is one fact, one date, one item.
A common misconception is that you can ask the other side to admit legal conclusions like “Admit you are negligent.” You can ask about the application of law to fact under CCP section 2033.010, but pure legal conclusions draw objections.
Requests for Genuineness of Documents
If you want the other party to admit that a document is genuine, attach a copy of the document as an exhibit and reference it by exhibit number in the request. Under CCP section 2033.030(c), document-genuineness requests do not count against the 35-request limit.
The consequence of failing to attach the document is an objection and refusal to answer. Lila, an attorney, referenced “Exhibit A” but forgot to attach it; the defendant objected and the court sustained the objection.
Signature and Verification
The propounding party’s attorney (or the self-represented party) signs the form at the end. The responding party’s answers, which come on a separate document, must be verified under oath under CCP section 2033.240. The original requests do not need verification, only signature.
Service, Deadlines, and Response Rules
Once DISC-020 is complete, you must serve it on every party who has appeared in the case. Service can be by personal delivery, mail, overnight delivery, fax (if agreed), or electronic service under CCP section 1010.6. You also prepare and keep a Proof of Service (POS-030).
The default response deadline is 30 days from the date of service under CCP section 2033.250. Mail service adds 5 calendar days under CCP section 1013. Electronic service adds 2 court days under CCP section 1010.6(a)(3).
The plain-English rule is count carefully. The consequence of a missed deadline is the loss of all objections, including privilege, under CCP section 2033.280(a). Henry, a defendant, missed the 35-day mailed deadline by two days and lost his attorney-client privilege objection forever.
A real example shows the math. If you serve DISC-020 by mail on June 1, 2026, the response is due by July 6, 2026 (30 + 5 days). If you serve by email on June 1, the response is due by July 3, 2026 (30 + 2 court days).
A common misconception is that the 5-day mail extension applies to electronic service. It does not. The two systems use different add-on days.
Form of Response
The responding party answers in a separate document, not on DISC-020 itself. Each answer must either admit, deny, or state an inability to admit or deny after reasonable inquiry, under CCP section 2033.220. Partial admissions and denials are allowed if the responding party clearly identifies what is admitted and what is denied.
The consequence of an evasive response is a motion to compel further responses under CCP section 2033.290. Sanctions of $250 to $1,000 or more are common when the court grants the motion.
Verification Requirements
The responding party signs a verification under penalty of perjury, confirming the answers are true. A response without a verification is treated as no response at all, as confirmed in Appleton v. Superior Court (1988) 206 Cal.App.3d 632.
The consequence of an unverified response is the same as a missed deadline: motion to deem admitted, plus mandatory sanctions. Priya, a defendant, sent timely answers without a verification, and the court deemed every request admitted.
Three Real-World Scenarios
The three scenarios below show how DISC-020 works in common civil cases. Each scenario uses a 2-column table to show the Step Taken and the Result that follows.
Scenario 1: Personal Injury — Disputed Liability
| Step Taken | Result |
|---|---|
| Plaintiff serves DISC-020 with 10 admissions about the crash | Defendant must respond within 30 days plus 5 for mail |
| Defendant denies the request, “Admit you ran the red light” | Plaintiff must prove that fact at trial |
| At trial, plaintiff proves the red light was run | Court awards cost-of-proof sanctions under CCP section 2033.420 |
Scenario 2: Breach of Contract — Document Genuineness
| Step Taken | Result |
|---|---|
| Plaintiff attaches the signed contract as Exhibit A to DISC-020 | Defendant must admit or deny the signature is genuine |
| Defendant admits the signature | Authenticity is established under Evidence Code section 1414 |
| Plaintiff skips authentication at trial | Trial moves faster and saves witness costs |
Scenario 3: Landlord-Tenant — Missed Deadline
| Step Taken | Result |
|---|---|
| Landlord serves DISC-020 by email on April 1, 2026 | Tenant’s response is due May 5, 2026 (30 + 2 court days) |
| Tenant fails to respond by the deadline | Landlord files a motion to deem requests admitted |
| Court grants the motion under CCP section 2033.280 | Tenant loses key defenses and faces sanctions |
Named Examples in Action
These named examples bring the rules to life. Each example shows a different angle of DISC-020.
Sarah Chen, a plaintiff in a slip-and-fall case in Los Angeles Superior Court, serves 30 admissions on the grocery store defendant. She asks the store to admit it had no inspection log for the day of the fall. The store denies. Sarah proves at trial that the log did not exist, and the court awards $14,200 in cost-of-proof sanctions under CCP section 2033.420.
Marcus Johnson, a small contractor sued for shoddy work, receives DISC-020 with 22 requests. He admits 5, denies 12, and states inability to answer 5 after reasonable inquiry. His verification is signed and timely. The plaintiff cannot move for sanctions, and the case proceeds with focused issues for trial.
Elena Rodriguez, a self-represented tenant in a habitability case, uses DISC-020 to ask her landlord to admit the heater was broken from December 1 to February 15. The landlord admits. Elena uses the admission at trial under CCP section 2033.410 and wins a rent reduction without calling expert witnesses.
Mistakes to Avoid With DISC-020
Most discovery disasters trace back to a handful of avoidable errors. The list below covers the most common ones, each with the negative outcome that follows.
- Writing compound requests, which leads to objections that the request is impermissibly compound under CCP section 2033.060.
- Missing the 35-request limit without filing DISC-005, which lets the responding party ignore the excess requests.
- Forgetting to attach documents for genuineness admissions, which results in sustained objections and lost evidence.
- Failing to verify responses, which is treated as no response and triggers a deemed-admitted motion under CCP section 2033.280.
- Miscounting deadlines by mixing up the 5-day mail rule and the 2-court-day electronic rule, which causes blown deadlines and lost objections.
- Asking for pure legal conclusions, which produces objections and wastes one of your 35 requests.
- Serving admissions before the 10-day post-service window for plaintiffs, which makes the requests void under CCP section 2033.020.
- Filing DISC-020 with the court instead of just serving it, which violates Rule 3.250 and may draw clerk rejection.
- Using an outdated form revision, which can lead to clerk or opposing-counsel pushback on validity.
- Failing to meet and confer before a motion to compel further responses, which leads to denial of the motion under CCP section 2033.290(b).
Sanctions and Consequences
The Civil Discovery Act puts real teeth into DISC-020. The two main sanction tools are deemed admitted orders and cost-of-proof sanctions. Both can change the outcome of a case.
A deemed-admitted order is granted under CCP section 2033.280 when the responding party fails to serve a timely response. The court must grant the motion unless the responding party serves a substantially compliant, verified response before the hearing. Monetary sanctions are mandatory under the same section.
Cost-of-proof sanctions are granted under CCP section 2033.420 when a party denies a request and the propounding party later proves the matter at trial. The court awards reasonable attorney’s fees and costs incurred in proving the fact. Recent cases like Grace v. Mansourian (2015) 240 Cal.App.4th 523 confirm that bare denials in the face of strong evidence trigger fee awards.
The plain-English rule is deny only when you have a real basis. The consequence of reckless denials can run into tens of thousands of dollars in fees. Tomás, a defendant who denied liability in a clear rear-end collision, paid $32,500 in cost-of-proof sanctions after a one-day trial.
A common misconception is that you can avoid sanctions by saying, “I deny based on lack of information.” The court rejects this when the party had access to the information through reasonable inquiry, as held in Wimberly v. Derby Cycle Corp..
Withdrawing or Amending an Admission
A party who admits a fact and later regrets it has limited options. Under CCP section 2033.300, the court may permit withdrawal or amendment of an admission if the party shows that the admission was the result of mistake, inadvertence, or excusable neglect, and the propounding party will not be substantially prejudiced.
The plain-English rule is that withdrawal is hard, but possible. The consequence of denied withdrawal is that the admission stands and binds the party at trial. Rachel, a defendant who admitted ownership of a defective product by mistake, moved to withdraw and won, but only because she filed within 60 days and the plaintiff had not yet relied on the admission.
A common misconception is that you can simply send an amended response and erase the prior admission. You cannot. The court must approve withdrawal by formal motion.
Do’s and Don’ts of DISC-020
Use the lists below as a quick reference before serving or responding to admissions. Each item includes the why behind it.
Do’s:
- Do use the most recent DISC-020 form revision, because outdated versions can be rejected.
- Do keep each request to a single fact, because compound requests draw valid objections.
- Do calendar the response deadline the day you serve, because missed deadlines cost you objections.
- Do attach documents for genuineness requests, because the responding party cannot admit a document they have not seen.
- Do verify every response under penalty of perjury, because unverified responses are treated as no response at all.
Don’ts:
- Don’t exceed 35 requests without a DISC-005 declaration, because excess requests are unenforceable.
- Don’t ask for legal conclusions, because they invite objections and waste your request count.
- Don’t file DISC-020 with the court, because Rule 3.250 bars filing of discovery.
- Don’t deny without a factual basis, because cost-of-proof sanctions can follow.
- Don’t ignore meet-and-confer duties, because skipping them sinks motions to compel.
Pros and Cons of Using DISC-020
The form is powerful, but it has trade-offs. The lists below capture the main pros and cons.
Pros:
- Pros: Narrows trial issues, because admitted facts need no proof at trial.
- Pros: Pressures opponents, because reckless denials risk cost-of-proof sanctions.
- Pros: Cuts costs, because admissions reduce the need for witnesses and exhibits.
- Pros: Establishes documents, because genuineness admissions skip authentication steps.
- Pros: Free template, because the Judicial Council provides DISC-020 at no charge.
Cons:
- Cons: Strict deadlines, because a 30-day miss can deem matters admitted.
- Cons: 35-request cap, because complex cases may need a DISC-005 declaration.
- Cons: Drafting precision required, because vague or compound requests fail.
- Cons: Verification burden, because every response needs an oath.
- Cons: Limited withdrawal, because CCP section 2033.300 sets a high bar.
Key Entities and How They Relate
Several people, courts, and rules shape DISC-020 practice. Understanding their roles makes the form easier to use.
The Judicial Council of California drafts and updates the form. The California Legislature enacts the Civil Discovery Act. The Superior Courts hear motions to compel and motions to deem admitted. The California Courts of Appeal decide cases like St. Mary v. Superior Court (2014) 223 Cal.App.4th 762 that interpret these rules.
The propounding party drafts and serves the form. The responding party answers under oath. Attorneys, paralegals, and self-represented litigants all interact with these entities. The relationship is hierarchical: the Legislature sets the rules, the Judicial Council provides forms, and the courts enforce both.
Recap of Key Court Rulings
California appellate courts have shaped the rules around DISC-020 over decades. A few rulings stand out and guide today’s practice.
In Wimberly v. Derby Cycle Corp. (1997) 56 Cal.App.4th 618, the court held that a denial without reasonable basis triggers cost-of-proof sanctions, even when the denying party held an honest but unreasonable belief. In St. Mary v. Superior Court (2014) 223 Cal.App.4th 762, the court ruled that substantial compliance with response requirements can defeat a deemed-admitted motion. In Grace v. Mansourian (2015) 240 Cal.App.4th 523, the court affirmed sanctions where a defendant denied liability in a clear rear-end collision.
The plain-English takeaway is that judges expect honest, well-supported responses. The consequence of cutting corners is sanctions, fee awards, and lost cases.
FAQs
Is DISC-020 mandatory in California civil cases?
No. The form is optional, but most attorneys use it because the Judicial Council template satisfies the requirements of CCP section 2033.060 and is widely accepted by courts and opposing counsel.
Can a self-represented party use DISC-020?
Yes. Self-represented litigants use the same DISC-020 form as attorneys, sign in place of counsel, and follow the same service and deadline rules under the Civil Discovery Act.
Do I file DISC-020 with the court?
No. Under California Rules of Court, Rule 3.250, discovery requests are served on parties only and not filed unless the court orders filing for a motion or appeal record.
Is there a limit on how many admissions I can serve?
Yes. In unlimited civil cases, the cap is 35 fact or law admissions per opposing party under CCP section 2033.030, but document-genuineness admissions are unlimited.
Can I get more than 35 admissions if I need them?
Yes. You may serve a DISC-005 Declaration for Additional Discovery under CCP section 2033.040, and the opposing party may move for a protective order if they object.
Does the response deadline change with mail service?
Yes. Mail service adds 5 calendar days under CCP section 1013, making the response due 35 days after service instead of 30.
Can I withdraw an admission after I make it?
Yes. A party may move under CCP section 2033.300 to withdraw or amend, but must show mistake or excusable neglect and no substantial prejudice to the other side.
Will I face sanctions for a late response?
Yes. Under CCP section 2033.280, a court must impose monetary sanctions on the responding party who failed to serve a timely response and grant the motion to deem the requests admitted.
Can I object to a request for admission?
Yes. You may object on grounds such as relevance, privilege, vagueness, or compound form, but objections must be stated in the response and supported under CCP section 2033.230.
Are admissions usable in other lawsuits?
No. Under CCP section 2033.410(b), an admission is binding only in the current action and cannot be used against the party in any other proceeding.
Does electronic service add days to the deadline?
Yes. Under CCP section 1010.6, electronic service adds 2 court days, so a response normally due in 30 days is due in 32 court days from the e-service date.
Can the court award attorney’s fees for false denials?
Yes. Under CCP section 2033.420, a court must award reasonable fees and costs to a party who proves a fact at trial that the opponent denied without reasonable basis.
