To file a motion to quash a subpoena, you ask the issuing court to cancel or narrow it before the compliance date, citing a ground the rules recognize — privilege, undue burden, geographic overreach, or too little time to comply. In federal court, Rule 45 controls the process, and it rewards speed. Miss the compliance date without filing, and you have likely waived your challenge.
File Before the Compliance Date
Federal Rule of Civil Procedure 45 requires a “timely motion” but does not set a day count. Courts read that to mean the motion must be on the judge’s desk before the date the subpoena tells you to appear or produce. If the subpoena orders a deposition on March 20, your motion needs to be filed before March 20. One day late can be treated as acceptance.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45
Work backward from that date. You need time to draft, time for the clerk to accept the filing, and, in many courts, time to obtain a hearing date before you finalize the paperwork. Waiting until the last week is a common mistake.
Consider Written Objections First for Document Subpoenas
If the subpoena demands documents, electronically stored information, or property inspection, you have a lighter option under Rule 45(d)(2)(B): serve written objections directly on the attorney or party who issued it. The deadline is the earlier of 14 days after service or the compliance date on the subpoena’s face.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45
Once objections are served, your duty to produce is suspended unless a court later orders otherwise. The burden shifts: if the requesting party still wants the documents, they have to go to court and file a motion to compel. Written objections are faster and cheaper than a motion, and they require no filing fee. For many people who receive a document subpoena out of the blue, this is the right first move.
Written objections do not cover every subpoena. If you were commanded to appear for a deposition, you need a motion to quash or a motion for a protective order. If the command is for live trial testimony, a motion to quash is the only route.
Grounds a Federal Court Will Accept
Inconvenience is not a ground. Federal law separates situations where a judge must quash from those where a judge may quash.
Grounds That Require the Court to Quash
Under Rule 45(d)(3)(A), the court must quash or modify a subpoena in four situations:
- It fails to allow a reasonable time to comply. A demand for thousands of documents in 48 hours fits here.
- It requires a non-party to travel more than 100 miles from where they live, work, or regularly do business in person for a trial, hearing, or deposition. Parties and their officers can be compelled farther within their home state; everyone else gets the 100-mile cap. The limit also governs where documents must be produced.
- It seeks privileged or otherwise protected material — attorney-client, doctor-patient, spousal, clergy, or a similar recognized protection — with no waiver or exception in play.
- It imposes an undue burden. Courts weigh volume, relevance, how specifically the request is described, and whether the same information is available elsewhere.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45
Grounds Where the Court May Quash
Rule 45(d)(3)(B) gives the court discretion in two more situations: subpoenas that would force disclosure of trade secrets or confidential commercial information, and subpoenas seeking an unretained expert’s opinion. The court can let those subpoenas stand if the requesting party shows a substantial need and agrees to reasonable compensation.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45
Procedural Defects
Service problems are their own ground. A subpoena left with the wrong person, mailed without following the applicable rules, or issued by someone without authority may be invalid regardless of content. A subpoena that fails to describe the requested documents with reasonable specificity — “all files relating to your business,” with no date range or topic — can be challenged as overly broad.
What Goes in the Motion Package
Local rules vary, but the core documents are consistent.
The motion itself opens with the case caption (court, case number, parties). It states the facts: date of service, what the subpoena demands, and why the court should quash or modify it. The legal argument connects those facts to the specific ground you are relying on. Be concrete. “This subpoena is overly broad” is not an argument. “This subpoena demands every email I have sent in the last ten years without limiting by topic or custodian” is.
A supporting declaration or affidavit carries any fact the court cannot see from the subpoena alone: the cost of compliance, the volume of documents, the basis for a privilege claim. On an undue burden argument, the declaration is usually the most important piece.
A proposed order gives the judge something to sign. Draft it as though you have already won: “The subpoena served on [your name] on [date] is hereby quashed.”
A notice of hearing tells all parties the date, time, and location. Call the clerk for an available date before you finalize it. Some courts schedule motions administratively after filing; check local rules.
A certificate of service, signed by you, confirms that copies of the entire package went to the attorney or party who issued the subpoena.
Many courts also require a meet-and-confer certification stating you made a good-faith effort to resolve the dispute before filing. Even where it is not required, calling the other side first can narrow the scope by agreement and save the motion entirely.
Where to File and How to Serve
File in the court where compliance is required. In federal cases, that is the district court for the area where the subpoena directs you to appear or produce — which may not be the court where the underlying lawsuit is pending.1Legal Information Institute. Federal Rules of Civil Procedure Rule 45 Filing options depend on the court: in person, by mail, or through the electronic system.
Motion filing fees are typically modest, and some courts charge nothing for a motion filed in an existing case. If cost is a barrier, federal courts allow an in forma pauperis application on a showing of financial hardship.
After filing, serve the complete filed package on the attorney or party who sent the subpoena. Court rules commonly allow service by mail or electronic means. Skip this step and your motion can be struck.
The Hearing and What the Judge Can Do
The issuing party will file a written response arguing the subpoena should stand. Read it closely before the hearing.
At the hearing, both sides present oral argument. Judges ask pointed questions on undue burden — they want specifics on cost and volume, not generalities. On privilege, be ready to identify each document or communication at issue and the privilege that covers it.
The judge has three options. Grant the motion and quash. Deny it and order compliance. Or, most commonly in practice, modify the subpoena — a narrower date range, fewer categories, cost-shifting to the requesting party. The ruling may come from the bench or in a written order days later.
Recovering Costs When the Subpoena Was Abusive
Rule 45 places a duty on the party and attorney who issue a subpoena to take reasonable steps to avoid imposing undue burden or expense. When they breach that duty, the court can impose sanctions, including lost earnings and reasonable attorney’s fees. If you succeed in quashing a subpoena that was oppressive or issued in bad faith, recovering your costs is a realistic possibility worth pressing.1Legal Information Institute.

Ignoring the Subpoena Is the Worst Option
A subpoena is a court order. Ignoring it, or missing the deadline for a challenge, exposes you to contempt. Penalties are at the court’s discretion and can include monetary sanctions and, in extreme cases, arrest. The more common outcome is an order compelling immediate compliance plus attorney’s fees for the party who had to bring you back to court. That combination almost always costs more than handling the subpoena properly on the first pass.
If your motion is denied, comply by the deadline the court sets. Continued refusal after a denial reopens the contempt exposure. In rare cases where the denial is clearly wrong on a significant legal point, emergency relief from a higher court may be available, but that path requires separate counsel.
