How to Fill Out and Serve a Request for Discovery Form

To fill out and serve a request for discovery form in federal court, draft the request with a proper caption, a definitions section, and clearly numbered questions that match the discovery rule you’re using, then deliver it to the opposing party through the court’s electronic filing system or another method allowed by Rule 5. One thing has to happen first, though: you cannot serve any discovery until the parties have held the Rule 26(f) planning conference.

Hold the Rule 26(f) Conference First

Rule 26(d) bars any party from seeking discovery before the Rule 26(f) conference takes place, unless the case is exempt or the court orders otherwise. The conference itself has to happen at least 21 days before the court’s scheduling conference or the due date for a scheduling order.¹

At the meeting, you and the other side discuss claims and defenses, identify what discovery you’ll need, and build a proposed plan covering topics, formats for electronically stored information, and a timeline. That plan goes to the judge, who uses it to set deadlines. Serve a request before this step and expect it to be challenged as premature.

Within 14 days after the conference, both sides also exchange initial disclosures: witnesses with relevant knowledge, documents and data you may use to support your case, a damages computation with supporting documents, and any insurance policy that could cover a judgment.¹ Those disclosures give you a baseline, so your formal requests can target what’s missing.

Pick the Right Form for What You Need

Three written discovery tools do most of the work, and each one has its own rule and its own limits.

Interrogatories (Rule 33)

Interrogatories are written questions the other party answers under oath. Rule 33 lets you serve up to 25 interrogatories, including all discrete subparts, without court permission.² Subparts count individually, so a question that really asks three things uses three slots. Need more? Get leave of court or a written agreement from the other side.

Use interrogatories for facts: witness names, dates, how damages were calculated, the factual basis for a claim. Don’t use them to request physical documents.

Requests for Production (Rule 34)

Rule 34 lets you ask the other party to produce documents, electronically stored information, and tangible things for inspection, copying, or testing, and to allow entry onto designated property for inspection.³ Contracts, emails, texts, medical records, photographs, and spreadsheets all fit here.

Requests for Admission (Rule 36)

Under Rule 36, you ask the other party to admit or deny specific factual statements or the authenticity of particular documents. Admissions narrow the issues so neither side wastes trial time on facts nobody disputes. The stakes are real: if the other party fails to respond within 30 days, every matter in the request is automatically deemed admitted.⁴

What Goes on the Form

Every discovery request starts with a caption at the top identifying the court, the names of the parties, and the case number assigned by the clerk.⁵ It’s the same header you’d use on any court filing. Below the caption, identify who is sending the requests (the propounding party) and who must answer them (the responding party).

Many courts’ websites and administrative offices publish blank templates with the caption layout and signature blocks already formatted. Using those avoids technical objections about margins, font size, or local-rule layout.

Most well-drafted forms include a definitions section near the top. If you want “communication” to include emails, letters, voicemails, and text messages, say so. Defined terms stop the other side from reading your requests as narrowly as possible. Follow definitions with numbered instructions explaining how you want responses formatted. Should documents arrive in their original order? Labeled by request number? Produced electronically? Spell it out.

Number each request sequentially. If you serve a second set of interrogatories later, pick up where the first set left off (start at 26, not 1). Consistent numbering keeps answers, objections, and any follow-up motions easy to track.

Draft Each Request So It Can’t Be Easily Objected To

Discovery covers any non-privileged matter relevant to a claim or defense and proportional to the needs of the case. Courts weigh the importance of the issues, the amount in controversy, each party’s access to the information, available resources, and whether the burden outweighs the likely benefit.¹ Keep that standard in mind as you write. Requests that clearly exceed it draw objections and sometimes sanctions.

For interrogatories, ask for facts, not legal conclusions. “State the date, time, and location of each meeting between you and the plaintiff” is clean. “Explain why you believe you are not liable” is really asking for legal argument and will be objected to. Each question should target one topic. Compound questions that bundle three or four inquiries get counted as multiple interrogatories against your 25-question limit.

For production requests, describe documents by type, date range, author, or subject matter. “All documents related to the accident” is weak. “All photographs taken at the intersection of Main Street and Elm Avenue between January 1 and March 15, 2025” is specific enough that the responding party can conduct a reasonable search. Requests for “any and all documents” with no further limitation are a red flag for opposing counsel and for the court.

For admission requests, phrase each statement so it can be cleanly admitted or denied. Statements that bundle facts together (“Admit that the defendant was driving 80 miles per hour and failed to signal”) invite partial denials and murky responses. Break compound facts into separate requests.

Serve the Request on the Opposing Party

Once the forms are finished, service is what starts the response clock. Rule 5 allows several methods: hand delivery, leaving the document at the person’s office or home, mailing it to the last known address, or filing it through the court’s electronic filing system.⁵

Electronic service through the court’s e-filing system is the most common approach in federal court. If you serve by e-filing, no certificate of service is required.⁵ For any other method, file a certificate of service showing when and how the document was delivered. The certificate doesn’t include the discovery questions themselves; it only proves you served them and triggers the deadline.

Email or other electronic service outside the court’s filing system is only valid if the other party has consented in writing to that method.⁵ Electronic service is complete when you hit send, but it becomes ineffective if you learn the transmission failed.

The 30-Day Response Clock

After service, the responding party has 30 days to provide written answers or objections. The deadline is the same for interrogatories under Rule 33,² production requests under Rule 34,³ and admissions under Rule 36.⁴

You and the other side can shorten or extend that period through a written stipulation under Rule 29, as long as the new timeline doesn’t interfere with any court-ordered deadlines for completing discovery, hearing motions, or going to trial.⁶ If the extension would conflict with those dates, you need the court’s approval. Note the service date on your calendar immediately; the 30-day clock starts running right away.

Keep Your Own Disclosures and Responses Current

Discovery runs both directions, and your own disclosures and responses are not one-and-done. Under Rule 26(e), a party who has made an initial disclosure or responded to an interrogatory, production request, or admission request must supplement or correct that response in a timely manner if the party later learns the information was incomplete or incorrect.¹ This obligation runs through trial.

The one exception: supplementation isn’t required if the corrective information has already been made known to the other parties during discovery or in writing. Don’t rely on that too heavily. Courts have held that identifying a witness in passing during a deposition doesn’t satisfy the duty to formally supplement a prior disclosure. Failing to supplement can lead to exclusion of the undisclosed evidence at trial, which is the kind of surprise that loses cases.
