Discovery motions are formal requests that ask a judge to intervene in pretrial evidence exchange, either to force a party to produce information, to block or narrow a request, to quash a subpoena, or to sanction misconduct. Most of these motions live under Rule 37 of the Federal Rules of Civil Procedure, and the rule builds in real financial consequences: when a motion to compel is granted, the court must order the losing side to pay the winner’s reasonable expenses, including attorney fees, unless a narrow exception applies.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions That fee-shifting rule shapes almost every strategic choice around these motions.
Motion to Compel
The motion to compel is the most common discovery motion. You file one when the other side has failed to respond to a request, has given evasive or incomplete answers, or has objected to producing something you believe you are entitled to receive. Rule 37(a) covers the standard triggers: a deponent who refuses to answer at a deposition, a party who does not answer interrogatories, and a party who does not produce documents or permit inspection.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
A well-drafted motion identifies the specific request, quotes the inadequate response, and explains why the information is discoverable. Under Rule 26, discovery reaches any non-privileged matter that is relevant to a claim or defense and proportional to the needs of the case.2Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery Your motion needs to hit both marks.
Then comes the money question. If the court grants your motion, or if the opposing party finally produces the information only after you file, the court must order that party or their attorney to pay your reasonable expenses in bringing the motion, including attorney fees.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions The court will skip the fee award only if the losing party’s position was substantially justified, if you did not try to work things out first, or if other circumstances make the award unjust.
The reverse applies too. If your motion is denied, the court must order you to pay the other side’s expenses in opposing it, unless your motion was substantially justified.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions A weak motion to compel is not a free shot.
Motion for a Protective Order
A protective order is the opposite request. Instead of forcing production, it asks the court to limit or block it. Any party or person facing a discovery request can seek protection from demands that are annoying, embarrassing, oppressive, or unduly burdensome.2Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery
Courts have wide discretion to shape the order. Under Rule 26(c), a judge can:
- Forbid the disclosure or discovery altogether
- Specify terms, including time and place, or allocate costs
- Require a different discovery method than the one requested
- Limit the scope of discovery to specific topics
- Designate who may be present during a deposition
- Require that a deposition be sealed and opened only by court order
- Require that trade secrets or confidential commercial information not be disclosed, or be disclosed only in a specified way
The party seeking the order must show good cause. Vague discomfort will not do it. A company invoking trade secret protection has to identify what is confidential and explain the competitive harm from disclosure. Blanket claims that everything is proprietary rarely succeed.
Motion to Quash a Subpoena
Discovery reaches beyond the parties. Third parties can be subpoenaed under Rule 45 to produce documents or give testimony, and when a subpoena is unreasonable, the recipient or a party in the case can move to quash or modify it.
The court must quash or modify a subpoena that:
- Fails to allow a reasonable time to comply
- Requires compliance beyond the geographic limits set by the rule
- Demands privileged or otherwise protected material, with no applicable exception or waiver
- Imposes an undue burden on the recipient
Once one of those four grounds is established in a timely motion, the court has no choice.3Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
The court also has discretion, not an obligation, to quash or modify a subpoena that seeks trade secrets or other confidential commercial information, or that demands an unretained expert’s opinions on matters outside specific events in the case. Rather than quashing outright, the judge can permit production under specified conditions if the requesting party shows a substantial need that cannot be met another way and ensures the subpoenaed person is reasonably compensated.3Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
Sanctions Motion for Lost Electronic Evidence
The duty to preserve relevant evidence begins before any formal discovery request. Once a party reasonably anticipates litigation, it must take reasonable steps to preserve electronically stored information that could be relevant. Failing to do so is spoliation, and the available consequences depend on how bad the conduct was.
Rule 37(e) sets up a two-tier framework. If a party failed to take reasonable steps to preserve ESI, and the information is lost and cannot be restored or replaced through additional discovery, the court can order measures “no greater than necessary” to cure the resulting prejudice.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions That could mean allowing further discovery from other sources or adjusting how a particular issue gets proven.
The severe sanctions are reserved for intentional destruction. Only when the court finds that a party acted with the intent to deprive the other side of the evidence can it presume the lost information was unfavorable, instruct the jury to draw that presumption, or dismiss the case or enter default judgment.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Negligence can still carry consequences, but the case-ending sanctions require proof of calculated conduct.
Meet-and-Confer Before You File
Before filing most discovery motions, the moving party must certify that they tried in good faith to resolve the dispute without court involvement.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions A motion to compel filed without this certification will likely be denied.
The requirement runs both ways. A party seeking a protective order must also certify an attempt to resolve the dispute with the requesting side first.2Legal Information Institute. Federal Rules of Civil Procedure Rule 26 – Duty to Disclose; General Provisions Governing Discovery In practice, that means a substantive letter or email explaining your position and a reasonable window for the other side to respond. Judges recognize the difference between real negotiation and a boilerplate note fired off the morning of filing. Some courts go further and require the parties to request an informal discovery conference with the judge before any motion can be filed. Check the scheduling order before you draft anything.
Deadlines That Trigger Fights
Most discovery disputes start when a response is late. Under the federal rules, the responding party has 30 days after service to answer interrogatories,4Legal Information Institute. Federal Rules of Civil Procedure Rule 33 – Interrogatories to Parties and the same 30-day window applies to document requests under Rule 34.5Legal Information Institute. Federal Rules of Civil Procedure Rule 34 – Producing Documents, Electronically Stored Information, and Tangible Things The parties can agree to extend those deadlines, or the court can adjust them by order, but a party that runs past 30 days with no response or extension is already out of compliance and exposed to a motion to compel.
The outer boundary on all of this is the scheduling order. Every federal case gets one, typically within 90 days after a defendant is served or 60 days after a defendant appears, whichever comes first. That order sets the discovery cutoff, and discovery motions filed after it are almost always denied absent a good-cause showing.6Legal Information Institute. Federal Rules of Civil Procedure Rule 16 – Pretrial Conferences; Scheduling; Management
The rules themselves do not set a specific window between a discovery failure and the deadline to move to compel. The trigger is the inadequate response paired with a failed attempt to resolve it informally.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions Local rules often add their own timing requirements. And even where none apply, waiting months to complain signals to the judge that the information was not important enough to fight for.
Sanctions When a Party Defies a Discovery Order
Once a court has ordered discovery and a party disobeys, the consequences move well past fee-shifting. Rule 37(b)(2) gives the judge a menu:
- Deem specified facts established for purposes of the case
- Prohibit the disobedient party from supporting or opposing designated claims or defenses, or from introducing certain evidence
- Strike pleadings in whole or in part
- Stay further proceedings until the order is obeyed
- Dismiss the action in whole or in part, or enter a default judgment
- Treat the failure as contempt of court
On top of any of these, the court must also order the disobedient party or their attorney to pay the reasonable expenses, including attorney fees, caused by the failure, unless it was substantially justified or other circumstances make the award unjust.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
Sanctions usually escalate. A first failure to comply typically draws fee-shifting and a warning. Repeated or willful conduct opens the door to the harsher options. Dismissal and default are reserved for cases where nothing less will do, but they happen when a party treats a court order as optional.
The Substantial Justification Safety Valve
“Substantially justified” appears throughout Rule 37, and it is what keeps ordinary discovery disagreements from turning every loss into a fee award. The standard is not that you were right. It is that your position had a legitimate basis and the dispute was genuine.1Legal Information Institute. Federal Rules of Civil Procedure Rule 37 – Failure to Make Disclosures or to Cooperate in Discovery; Sanctions
The defense cuts in both directions. If you resisted a request and the court ordered you to produce, you can still avoid paying the other side’s motion expenses by showing your objection was substantially justified. If you filed a motion to compel and lost, the same standard protects you from covering the other side’s opposition costs. The defense also reaches sanctions for failing to obey a court order, though the bar there is harder to clear, because at that point you are no longer arguing about the underlying discovery. You are explaining why you defied a direct instruction from the judge.
