How to File a Motion to Compel Answers to Interrogatories

To file a motion to compel answers to interrogatories, you confirm the other side’s response is legally deficient, attempt in good faith to resolve the dispute directly with opposing counsel, and then file a motion package with the court that includes a certification of that effort, a supporting memorandum, the interrogatories and responses at issue, and a proposed order. Federal Rule of Civil Procedure 37 requires the good-faith conferral before a judge will consider the motion, and skipping it is one of the fastest ways to get a well-founded motion denied.1Legal Information Institute.

Confirm You Have Grounds to File

The responding party has 30 days after service of interrogatories to answer or object.2Legal Information Institute. Federal Rule of Civil Procedure 33 – Interrogatories to Parties Three situations give you grounds to compel.

The first is a complete failure to respond. When the deadline passes and nothing has been served, the silence itself is the deficiency.

The second is evasive or incomplete answers. Rule 33 requires each interrogatory to be answered separately and fully in writing under oath.2Legal Information Institute. Federal Rule of Civil Procedure 33 – Interrogatories to Parties A response that points to “documents previously produced” without identifying which ones, or that answers a different question than the one asked, does not meet that standard. For purposes of a motion to compel, Rule 37 treats an evasive or incomplete answer the same as no answer.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery Sanctions

The third is improper objections. Objections must be stated with specificity. Blanket labels like “overly broad” or “unduly burdensome” without explanation, and boilerplate objections pasted before every answer, are vulnerable to a motion to compel.2Legal Information Institute. Federal Rule of Civil Procedure 33 – Interrogatories to Parties The same goes for privilege objections that assert the privilege but don’t describe the withheld materials in enough detail for you to evaluate the claim, as Rule 26 requires.3Legal Information Institute. Federal Rule of Civil Procedure 26 – Duty to Disclose General Provisions Governing Discovery

One boundary to check before you file: federal rules cap each party at 25 written interrogatories, including all discrete subparts, unless the parties stipulate otherwise or the court grants leave to exceed the limit.2Legal Information Institute. Federal Rule of Civil Procedure 33 – Interrogatories to Parties If you served more than that without permission, a judge is unlikely to compel answers to the extras.

Meet and Confer First

Rule 37 requires your motion to include a certification that you conferred, or attempted to confer, in good faith with the other side to obtain the responses without court action.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery Sanctions Judges enforce this. A halfhearted effort, or none at all, can sink an otherwise solid motion.

In practice, that means a letter or email to opposing counsel identifying each interrogatory you consider inadequately answered or improperly objected to, explaining why, and giving a reasonable deadline to supplement. Be specific. Instead of “your responses are deficient,” write something like: “Your answer to Interrogatory No. 7 says ‘see documents produced’ without identifying which of the 3,000 pages contain the answer.” That kind of detail gives the other side a chance to fix the problem and shows the court you tried.

Keep records. Save the emails, log the phone calls, note the dates. This correspondence goes into your motion filing, and a thorough paper trail is your defense if the other side later claims you never tried to work it out.

Assemble the Motion Package

The motion is the document that asks the court for an order compelling responses. It needs the case caption (court name, case number, party names), a clear statement of the relief you want, and a legal argument explaining why the responses fall short. Most courts expect the argument in a supporting memorandum or brief filed with the motion, citing the applicable rules.

Along with the motion and memorandum, include:

  • A declaration or affidavit describing your meet-and-confer efforts, with the correspondence attached as exhibits.
  • Copies of the interrogatories you served.
  • Copies of the responses or objections you received.
  • A proposed order for the judge to sign.

Some courts require a separate statement pairing each disputed interrogatory with the response and your reason for seeking a further answer. Local rules vary on format, and this is where an otherwise strong motion can stall. Check your court’s local rules and the individual judge’s practices before filing.

File and Serve

File the motion package with the court clerk. Most federal courts require electronic filing through CM/ECF. State courts vary: some require e-filing, some still accept paper. Federal courts do not charge a separate fee for discovery motions; state court fees vary by jurisdiction.

Serving a motion is simpler than the formal service of process used for a complaint and summons. Under Rule 5, you can serve by filing through the court’s electronic system (which notifies registered users automatically), by other electronic means the recipient has agreed to in writing, or by mail or hand delivery. If you serve through the court’s e-filing system, no separate certificate of service is required.4Legal Information Institute. Federal Rule of Civil Procedure 5 – Serving and Filing Pleadings and Other Papers For any other method, file a proof of service showing the date and manner of delivery.

What Happens After You File

The opposing party gets a window to file a written opposition. The federal rules don’t set a single default deadline for opposition briefs on non-dispositive motions; local rules control, and the timeframe typically runs around 14 days. Confirm the exact deadline in your court’s local rules or the judge’s individual practices.

In opposition, the other side may argue their answers were adequate, their objections valid, or the interrogatories improper. They may also seek a protective order under Rule 26(c), asking the court to limit discovery based on undue burden, trade secrets, or other confidential information.3Legal Information Institute. Federal Rule of Civil Procedure 26 – Duty to Disclose General Provisions Governing Discovery

The court may hold a hearing or decide on the papers. When privilege is at issue, the judge can review the disputed materials in camera before ruling on disclosure. The ruling takes one of three forms: granted, denied, or granted in part. Partial grants are common. When the motion is granted, the order sets a deadline for the other side to provide complete answers.

The Fee-Shifting Risk Runs Both Ways

If the motion is granted, the court must order the party whose conduct made the motion necessary, their attorney, or both to pay your reasonable expenses, including attorney’s fees. The rule uses “must,” not “may.” A court can decline to award expenses only where you filed without a good-faith effort to resolve the dispute, the opposing position was substantially justified, or other circumstances would make the award unjust.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery Sanctions

The rule works the same way in reverse. If the motion is denied, the court must order you or your attorney to pay the opposing party’s reasonable expenses in fighting it, unless your motion was substantially justified or the award would be unjust.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery Sanctions Filing a weak motion can cost you real money. When the motion is granted in part and denied in part, the court has discretion to apportion expenses as it considers fair.

If They Still Refuse After the Order

Winning the motion doesn’t always end the dispute. When a party disobeys a discovery order, courts have broad authority to sanction the noncompliance, including:

  • Ordering that the disputed facts be treated as established in your favor.
  • Barring the disobedient party from introducing certain evidence or supporting specific claims or defenses.
  • Striking pleadings in whole or in part.
  • Staying proceedings until the party complies.
  • Dismissing the noncomplying party’s claims or entering default judgment against them.
  • Treating the failure as contempt of court, which can carry fines or jail time.

On top of any of those, the court must also order the disobedient party and their attorney to pay reasonable expenses, including attorney’s fees, caused by the failure, unless the failure was substantially justified or the award would be unjust.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery Sanctions

Judges typically impose lesser sanctions first and reserve dismissal or default for repeated or willful defiance. The range of penalties is deliberately severe because the discovery system depends on compliance, and a party who treats a court order as optional is gambling with the whole case.
