Handling discovery correspondence in federal litigation comes down to four habits: know what each written request is for, meet the 30-day response clock, say something specific instead of boilerplate, and keep a clean record of everything you send and receive. The Federal Rules of Civil Procedure set the deadlines, caps, and consequences, and the consequences run all the way to dismissal. What follows is how the exchange actually works, in the order you’ll encounter it.
What Has to Happen Before You Send Anything
Formal discovery correspondence cannot start until the parties hold their Rule 26(f) planning conference. That meeting must take place as soon as practicable and no later than 21 days before the court’s scheduling conference or scheduling order deadline.1Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery At the conference the parties build a joint discovery plan covering subjects for discovery, timelines, the format for electronic information, how privilege claims will be handled, and whether to ask the court for a clawback order under Federal Rule of Evidence 502. The plan goes to the court and governs the correspondence that follows.
Rule 26(a)(1) also requires each side to hand over basic information without being asked: names and contact details for people likely to have relevant knowledge, copies or descriptions of supporting documents and electronic files, a damages computation with underlying materials, and any applicable insurance agreements.1Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery These initial disclosures are due within 14 days after the planning conference unless the court sets another schedule. Narrow exceptions aside — deposing a witness about to leave the country, for instance — nothing else goes out until the conference happens.
Preservation obligations run on a different clock. Once litigation is reasonably anticipated, each party must take steps to keep relevant documents and electronic data from being deleted or overwritten. That usually means a written litigation hold that suspends automatic deletion for the relevant custodians and systems. A demand letter, a regulatory inquiry, or an internal decision to sue can all trigger the duty.
The Three Forms of Written Discovery
Formal discovery correspondence takes three main shapes. Each has its own rule, its own purpose, and its own trap.
Requests for Production
A Rule 34 request asks the other side to hand over documents, electronically stored information, or tangible items — writings, photographs, data compilations, sound recordings, and physical objects all qualify, so long as they are within the scope of discovery.2Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things, or Entering onto Land, for Inspection and Other Purposes You can also seek entry onto property to inspect, measure, or photograph it. The responding side has 30 days to answer in writing, either agreeing to produce or stating specific grounds for objection to each item or category.
Specificity is what makes a request work. “All documents related to the project” invites objections. A request that names a category, a time period, and a connection to a claim tends to produce actual documents with less friction. For electronic data, state the format you want. If you don’t, the responding party must state what format it intends to use, and the default is the format in which the data is ordinarily kept or another reasonably usable form. A party never has to produce the same electronic information in more than one format.2Legal Information Institute.

Interrogatories
Interrogatories are written questions answered under oath. Rule 33 caps each side at 25 interrogatories, counting subparts, unless the parties agree otherwise or the court permits more.3Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties Answers are due within 30 days of service. Because of the cap, every question has to earn its spot — identities of witnesses, the factual basis for a specific claim, whether certain documents exist.
Contention interrogatories, which ask the other side to state its legal positions or the facts supporting a particular claim, are expressly allowed: Rule 33 permits questions about opinions or contentions relating to facts or the application of law to facts.4United States Court of International Trade. Rule 33 – Interrogatories to Parties Courts sometimes defer the deadline for answering them until other discovery is further along.
Requests for Admission
A Rule 36 request asks the other party to confirm or deny specific facts or the genuineness of documents. The response is due in 30 days: admit, deny, or explain in detail why the matter cannot be truthfully admitted or denied.5Legal Information Institute. Federal Rules of Civil Procedure Rule 36 Miss the deadline and the matter is deemed admitted automatically. Undoing a deemed admission requires a court order. Cases quietly end this way.
Denying carelessly carries its own cost. If you deny a fact and the requesting party later proves it true, the court must order you to pay the reasonable expenses of making that proof, including attorney’s fees, unless the request was objectionable, the matter was of no substantial importance, you had reasonable ground to believe you might prevail, or there was other good reason for the denial.6Legal Information Institute.

Scope: Relevance and Proportionality
Every request has to fit inside two guardrails. Under Rule 26(b)(1), parties can seek any nonprivileged information relevant to a claim or defense, but only if the discovery is proportional to the needs of the case. Courts weigh the importance of the issues, the amount in controversy, each side’s relative access to the information, their resources, the importance of the discovery to resolving the case, and whether the burden outweighs the likely benefit.1Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Five years of email might be fair game in a major antitrust case and wildly disproportionate in a small contract fight. Draft to the case you have.
Serving the Papers and Watching the Clock
Discovery papers must be served on every other party. If a party has an attorney, service goes to the attorney under Rule 5. Electronic filing through the court’s system counts as service on any registered user the moment the document is filed; email or other electronic means consented to in writing, and physical delivery, also work.7Legal Information Institute. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers
A detail that surprises many litigants: discovery requests and responses generally are not filed with the court. Rule 5(d) prohibits filing interrogatories, document requests, requests for admission, and depositions until they are used in a proceeding or the court orders it.7Legal Information Institute. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers The exchange happens between the parties, off the public docket.
Responses are due 30 days after service across all three major discovery types. The parties can agree in writing under Rule 29 to extend or shorten the period, but an extension that would interfere with court-set deadlines for completing discovery, hearing motions, or going to trial needs court approval.8Legal Information Institute. Federal Rules of Civil Procedure Rule 29 Put every extension in writing. Log the date you served, the date you received, and the response deadline the moment the paper leaves or arrives.
Writing Responses and Objections
Each response has to address each request individually. You can provide the information, object with specific reasons, or do both — produce what isn’t disputed and object to the rest. Blanket objections copied across every request signal to opposing counsel and judges that you aren’t engaging with the obligation. A bare recital that a request is “overly broad and unduly burdensome,” without saying what the burden actually is, will not hold up when challenged. If you object, say why. If the objection applies only to part of a request, say which part and produce the rest.
Privilege Logs and Clawback Correspondence
Discovery often involves sensitive material. Either party can seek a protective order under Rule 26(c), asking the court to limit who sees certain information, require filings under seal, confine inquiry to specific topics, or protect trade secrets.1Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery The moving party must certify a good-faith attempt to resolve the issue before filing.
When you withhold documents on privilege or work-product grounds, Rule 26(b)(5)(A) requires a description detailed enough for the other side to assess the claim without revealing the privileged content. In practice that means a privilege log listing each document’s date, author, recipients, subject matter, and the basis for the claim. “Privileged communication” alone invites a challenge and can lead the court to order production. Keep the log current as you review.
If a privileged document slips out, Federal Rule of Evidence 502(b) provides a safety net: inadvertent disclosure does not waive the privilege if the holder took reasonable steps to prevent it and acted promptly to correct the error.9Legal Information Institute. Federal Rules of Evidence Rule 502 – Attorney-Client Privilege and Work Product; Limitations on Waiver The receiving party must then return, sequester, or destroy the materials promptly. A clawback agreement in the Rule 26(f) plan makes the correction routine instead of a crisis.
Keeping Your Own Record
Because the exchange is not on the docket, you are the custodian of the discovery record. That means tracking every request sent and received, every response and objection, every produced document, every extension, and every deadline. Months later, if a judge asks what happened, you need to reconstruct the full timeline — what was asked, what was produced, and when.
The record is more than requests and responses. Keep cover letters that accompany productions, emails confirming extensions, notes from meet-and-confer calls, and informal agreements about search terms or custodians for electronic discovery. Document management software and Bates numbering help, but the discipline is what matters: if you cannot find it quickly when a judge asks, it might as well not exist.
When Correspondence Breaks Down
Disputes are routine. The rules build in a mandatory negotiation step before anyone can bring one to a judge.
Meet and Confer
Before filing a motion to compel, the moving party must certify that it made a good-faith effort to resolve the dispute without court action.6Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Courts take this seriously. A motion filed without a real attempt can be denied on that ground alone. Put your position in a letter or email, propose a specific resolution, and give the other side a reasonable time to respond before escalating. That correspondence becomes part of the record if the dispute reaches a judge.
Motions to Compel and Fee Shifting
When negotiation fails, Rule 37(a) lets a party move to compel a response or production. A party facing overreach can seek a protective order under Rule 26(c). The fee-shifting rule in Rule 37(a)(5) gives these motions teeth: if a motion to compel is granted, the court generally must order the resisting party to pay the movant’s reasonable expenses, including attorney’s fees. If denied, the movant pays. If granted in part, the court can split the costs.6Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Fees are not awarded when the losing position was substantially justified or when other circumstances make the award unjust.
Sanctions
When a party disobeys a court order compelling discovery, Rule 37(b)(2) allows the court to treat disputed facts as established against the disobedient party, bar it from supporting or opposing certain claims, strike pleadings, stay the case, dismiss the action, enter default judgment, or hold the party in contempt. The court must also order the party or its attorney to pay the reasonable expenses caused by the failure unless the noncompliance was substantially justified. Spoliation of electronic evidence has its own escalation under Rule 37(e), reaching an adverse-inference instruction or case-ending sanctions when the loss was intentional.6Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Courts do not jump to the harshest sanctions without warning, but once a party has been ordered to comply and refuses, the progression is fast. Ignoring discovery correspondence or hoping the other side will not follow up is one of the quickest ways to lose a case on the merits of a timing problem.
