Discovery Letter: Deadlines, Objections, and Responses

To respond to a discovery letter, you generally have 30 days under the Federal Rules of Civil Procedure to serve written, sworn answers to any interrogatories, produce the requested documents and electronic files, and admit or deny each request for admission, raising specific objections where a request is improper. Miss that deadline on requests for admission and the statements are deemed admitted against you automatically.¹ State courts follow similar timelines, with exact deadlines that vary by jurisdiction.

Know What the Letter Is Actually Asking

A discovery letter usually bundles three different kinds of demands, and each one has its own response rules.

Interrogatories are written questions you answer in writing and under oath. In federal cases, the other side is capped at 25 interrogatories including subparts, unless the court or the parties agree otherwise.² Each one gets a separate, full answer. The person answering signs the responses; the attorney signs only the objections. If a business is responding, any officer or agent with access to the information can sign.

Requests for production ask for documents, physical items, and electronically stored information like emails, text messages, spreadsheets, and database records. You either produce the materials as they are kept in the ordinary course of business or you organize and label them to match the categories in the request.³ For electronic files, specify the production format, such as native files or searchable image copies.

Requests for admission are statements you must admit, deny, or explain in detail why you can do neither. You can say you lack enough information to answer, but only after a reasonable effort to find out. The point is to narrow what’s genuinely in dispute. The danger is silence: no response in 30 days and every statement is admitted.¹

The 30-Day Clock

The default deadline for all three request types is 30 days from the date you were served.²¹ The parties can agree in writing to extend or shorten that window, and the court can adjust it by order.⁴ An agreed extension still can’t push past the court’s deadlines for completing discovery, hearing motions, or going to trial. Responses are served on the requesting party, typically through the court’s electronic filing system or by mail.

Preserve Evidence Right Now

Your duty to preserve relevant evidence starts before the letter arrives. Once litigation is reasonably foreseeable, you have to stop routine destruction of documents and electronic data and put a litigation hold in place. That means telling everyone in your organization who might have relevant materials to stop deleting, overwriting, or discarding anything connected to the dispute.

If relevant electronic information is lost because you didn’t take reasonable steps to preserve it, and it can’t be restored, the court can order measures to cure the prejudice to the other side. If the court finds you acted with intent to deprive the other party of the evidence, the sanctions escalate: the jury can be instructed to presume the lost information was unfavorable to you, your case can be dismissed, or default judgment can be entered against you.⁵ Cases get lost here, before anyone sets foot in a courtroom.

Build Your Response

Gather Everything Responsive

Collect every document, file, and piece of information that falls within the scope of the requests. Search email accounts, shared drives, cloud storage, messaging apps, and physical files. If you’re responding for a company, coordinate with every department that might hold relevant records. This takes longer than people expect. Start the day the letter arrives.

Object With Specificity

You can object to individual requests, but boilerplate objections almost always backfire. The rules require you to state the specific grounds for each objection with enough detail that the other side and the court can evaluate it. If you’re objecting to only part of a request, identify the part you’re objecting to and respond to the rest. You also have to say whether you’re withholding any responsive materials based on the objection.³ Legitimate objections include that a request is overly broad, unduly burdensome, or seeks privileged information.

Log Privileged Materials

Attorney-client communications made for the purpose of getting legal advice don’t have to be produced, and materials your lawyer prepared in anticipation of the lawsuit are protected by the work-product doctrine. Both protections apply regardless of how relevant the material is.

When you withhold a document on those grounds, you can’t simply go quiet. You have to describe the withheld item in enough detail that the other side can evaluate the privilege claim, without revealing the protected content itself.⁶ In practice, that means a privilege log listing each withheld document, who created it, who received it, the date, the general subject, and the specific privilege claimed. A sloppy privilege log is one of the fastest ways to lose the protection entirely.

Verify Your Answers

Interrogatory answers are signed under oath by the person who provided them, not by the attorney, with any objections signed separately by counsel.² That verification puts you personally on the hook. Inaccurate or incomplete answers can lead to sanctions or perjury exposure later.

Protecting Sensitive Information

Discovery doesn’t make everything public. If your documents contain trade secrets, confidential business information, or sensitive personal data, you can ask the court for a protective order restricting how the other side uses and shares the material. You can also designate documents as confidential under the terms of a protective order, which limits access to attorneys and designated individuals involved in the case. Medical records carry additional HIPAA protections through a qualified protective order that restricts use of health information to the specific lawsuit and requires copies to be returned or destroyed when the case ends.

Large document productions sometimes leak a privileged document by accident. A clawback agreement, negotiated at the start of the case, is your safety net. Under federal law, an inadvertent disclosure of privileged material does not waive the privilege if the holder took reasonable steps to prevent the disclosure and acted promptly to fix it once discovered.⁷ For stronger protection, the parties can ask the court to enter an order under the same rule, which binds third parties who might later obtain the material.

Keep Your Responses Current

Responding to discovery isn’t a one-time event. If you later learn that any of your answers or disclosures were incomplete or incorrect in a meaningful way, you have to supplement or correct them in a timely fashion.⁶ The duty applies to interrogatory answers, document productions, and requests for admission. The exception is information already provided to the other side through other discovery channels or in writing. Expert disclosures carry the same duty, with updates due before pretrial disclosures.

Ignoring this is a common and costly mistake. If new documents surface or you realize an earlier answer was wrong, disclose the correction promptly. Sitting on it until trial can get the evidence excluded.

What Happens If You Don’t Respond

Meet and Confer First

Before anyone runs to the judge, the requesting party has to try to resolve the dispute directly with you. Federal rules require any motion to compel to include a written certification that the moving party made a good-faith effort to get the discovery without court involvement.⁵ A court won’t award expenses to a party that skipped straight to filing. Many disputes get resolved here.

Motion to Compel

If meet and confer fails, the other side can file a motion to compel. The court treats evasive or incomplete responses the same as no response at all. If the motion is granted, the court must generally require the losing side to pay the winner’s reasonable expenses, including attorney’s fees, unless the noncompliance was substantially justified.⁵ Those fees add up quickly.

Sanctions for Continued Noncompliance

If the court orders you to respond and you still don’t, the consequences escalate. Available sanctions include:

Treating the other side’s version of disputed facts as established for the rest of the case.
Barring you from introducing specific evidence or supporting certain claims or defenses.
Striking all or part of your pleadings.
Dismissing the case or entering default judgment against you.
Treating the failure as contempt of court.
Ordering the noncompliant party or their attorney to pay the other side’s reasonable expenses caused by the failure, on top of any other sanction.

These penalties can stack.⁵ Dismissal and default judgment are reserved for the worst behavior, but judges routinely impose fee-shifting and evidentiary penalties for ordinary stonewalling. Ignoring a discovery letter doesn’t make the case go away. It makes the case go worse.
