To file a motion to quash, you draft a written request asking the court to cancel or narrow a subpoena, identify the specific subpoena and your legal grounds under Federal Rule of Civil Procedure 45, and submit it to the clerk of the court where compliance is required before the compliance date on the subpoena or within 14 days of being served, whichever comes first. You then serve a copy on every other party in the case and file proof of that service. The steps are similar whether you are a party to the lawsuit or a non-party who received a subpoena, but local court rules add procedural details that matter.
File Before the Deadline Passes
Timing is where most motions fail. Under Rule 45(d)(2)(B), a written objection to a subpoena must be served before the earlier of the compliance date stated in the subpoena or 14 days after the subpoena is served on you.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena If the subpoena tells you to produce documents in seven days, you cannot wait until day 14. Miss the window and a court may treat your objection as waived no matter how strong the underlying argument is.
Criminal subpoenas run on a different clock. Under Federal Rule of Criminal Procedure 17, a motion to quash must be filed “promptly,” which judges interpret case by case. In either context, file as soon as you have identified your grounds. Waiting until the last day invites procedural problems that have nothing to do with the merits.
Grounds You Can Argue
Rule 45 divides objections into two groups. Some require the court to quash or modify a subpoena. Others give the court discretion to do so.
Grounds That Require Relief
A court must quash or modify a subpoena that:
- Fails to allow a reasonable time to comply.
- Requires a person to travel more than 100 miles from where they live, work, or regularly transact business in person, under the geographic limits in Rule 45(c).
- Demands disclosure of privileged or otherwise protected material where no exception or waiver applies. Attorney-client privilege, spousal privilege, and trial-preparation protections all fall here.
- Subjects the recipient to an undue burden, where the cost or disruption of compliance outweighs the legitimate value of the information.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
When your motion falls squarely into one of these, the court has no discretion. It must grant relief.
Grounds Where the Court May Act
A court may quash or modify a subpoena, but is not required to, when it demands trade secrets or other confidential research, development, or commercial information, or when it seeks an unretained expert’s opinions or information not describing specific events in dispute.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena Even here, if the requesting party shows a substantial need that cannot be met another way and agrees to reasonably compensate the person subpoenaed, the court can order compliance under protective conditions rather than cancel the subpoena.
Drafting the Motion
Pull the subpoena in front of you before you write. Every pleading filed in a federal case must include a caption with the court’s name, a case title listing the parties, and the file number.2Legal Information Institute. Federal Rules of Civil Procedure Rule 10 – Form of Pleadings Copy these details from the original document rather than paraphrasing. A mismatched case number can stop the clerk from linking your motion to the right file.
Some courts publish a motion-to-quash form or a general motion template through the clerk’s office or website. Many do not. If no form exists for your jurisdiction, you will draft the motion yourself following local rules for margins, font, and line spacing. Check the court’s website or call the clerk before you start typing.
Identify the Subpoena Exactly
State whether you are challenging a subpoena for live testimony or a subpoena for documents and records. If you only object to certain parts, say three out of ten document categories, specify which ones. A motion that vaguely asks the court to “quash the subpoena” gives the judge nothing to rule on.
State Your Grounds With Specifics
Tie each argument to one of the grounds Rule 45 recognizes. Common arguments include:
- Improper service, meaning the subpoena was not delivered to you personally or through an authorized method.
- Overbreadth, meaning the request sweeps in large volumes of material with no connection to the issues in the case.
- Undue burden, meaning compliance would impose extreme cost or disruption disproportionate to the value of the information.
- Geographic overreach beyond the 100-mile limit in Rule 45(c).1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena
- Privilege, meaning the subpoena targets material protected by attorney-client privilege, work-product doctrine, or another recognized privilege.
Be concrete. “This subpoena is burdensome” will not move a judge. “Producing 15 years of financial records for a contract dispute involving a single 2024 transaction would require 200 hours of staff time and cost approximately $30,000” might.
Build a Privilege Log if You Are Withholding Documents
If you are holding back documents on privilege grounds, Rule 45 requires you to expressly state the privilege and describe the withheld materials in enough detail, without revealing the privileged content itself, that the other parties can evaluate your claim.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 – Subpoena In practice that means a privilege log listing each withheld item by date, author, recipient, general subject matter, and the specific privilege asserted. Skip this and you often lose the privilege argument, because the court has nothing to evaluate.
Filing With the Court
Submit the completed motion to the clerk of the court where compliance with the subpoena is required. Many federal and state courts require electronic filing through a judicial e-filing portal where you upload the motion as a PDF. If you file in person, bring at least two extra copies so the clerk can date-stamp one for your records.
Most courts charge a filing fee. The amount varies by jurisdiction, from as little as $25 up to $75 or more. If you cannot afford the fee, you can file a separate application for a fee waiver, sometimes called proceeding in forma pauperis, documenting your income and financial situation. The clerk will not process the motion until the fee is paid or a judge grants the waiver.
Serving the Other Parties
After filing, deliver a copy of the motion to every other party in the case. Under Federal Rule of Civil Procedure 5, a written motion must be served on all parties, and where a party has an attorney, you serve the attorney rather than the party directly. Acceptable methods include hand delivery, mailing to the person’s last known address, or electronic transmission if the recipient has consented in writing or uses the court’s e-filing system.3Legal Information Institute. Federal Rules of Civil Procedure Rule 5 – Serving and Filing Pleadings and Other Papers
Then file a proof of service, sometimes called a certificate of service, with the court. This short document lists the date you served the motion, the method of delivery, and the name and address of each person who received a copy. Without it, a judge can refuse to consider the motion. Courts will not rule on a request the opposing side has not verifiably received.
Check for a Pre-Filing Conference Requirement
Some courts, particularly at the state level, require you to try to resolve the dispute informally before filing. That usually means contacting the attorney who issued the subpoena, explaining your objection, and seeing whether you can negotiate a narrower scope or an extended deadline. Where this step is required, you will typically include a certificate of conference with the motion stating that you made a good-faith effort and the parties could not reach agreement. Check local rules. Filing without this certificate where it is required can get your motion rejected on procedural grounds alone.
What Happens After You File
Once the motion is filed and served, the opposing party typically has a set window, often around 14 days depending on local rules, to file a written opposition arguing that the subpoena is valid. If an opposition is filed, the court will usually set a hearing.
At the hearing, the judge weighs your grounds against the opposing party’s response. The person challenging the subpoena generally carries the burden of showing why it should be quashed, so vague assertions will not do. You need to show with specifics that the subpoena falls within a recognized ground for relief.
The judge has three basic options:
- Grant the motion. The subpoena is canceled and you have no obligation to comply.
- Modify the subpoena. The judge narrows the scope, for example by limiting the date range of requested documents or reducing the topics for testimony, while leaving the rest intact.
- Deny the motion. The subpoena stands as written and you must comply.
If the Motion Is Denied
A denied motion means the subpoena is back in full force. You must produce the documents, appear for testimony, or both. Ignoring a subpoena after losing the motion is one of the most consequential mistakes a person can make in litigation.
A person who disobeys a valid subpoena faces contempt of court, which can carry fines, monetary sanctions payable to the other side, and in extreme cases a warrant for arrest or jail time until compliance occurs. If you believe the judge got the ruling wrong, the path forward is an appeal or a renewed request for a protective order with new arguments, not simply refusing to show up.
