Object Third Party Subpoena Guide – If you’ve received a subpoena from a party in a lawsuit you’re not involved in, you’re dealing with a third-party subpoena. This comprehensive guide explains how to object to a third-party subpoena under current US federal law, with practical steps, timelines, and protections tailored for individuals and businesses in the United States. Whether you’re in federal or state court, understanding your rights can prevent unnecessary burden, expense, or disclosure of confidential information.
Important disclaimer: This article provides general information based on the Federal Rules of Civil Procedure (FRCP) and trusted legal resources as of 2026. It is not legal advice. Laws vary by jurisdiction, and you should consult a qualified attorney immediately upon receiving a subpoena.
What Is a Third-Party Subpoena?
A third-party subpoena is a legal command issued by a party in ongoing litigation (the “issuing party”) to a non-party (you or your business) requiring the production of documents, electronically stored information (ESI), tangible things, or testimony. Unlike subpoenas directed at parties to the case, third-party subpoenas fall under FRCP Rule 45 in federal court.
Common examples include requests for business records, emails, financial documents, or witness testimony from vendors, employers, banks, or former employees who are not directly involved in the lawsuit.
Why Might You Receive a Third-Party Subpoena?
You may receive one if the issuing party believes you possess relevant information or documents that could help prove their case. Common scenarios include:
- Employment or HR records in divorce, discrimination, or wage disputes
- Financial or banking records in fraud or contract cases
- Medical or customer data in personal injury or product liability matters
- Vendor or supplier records in commercial litigation
The subpoena is designed to aid discovery but must comply with strict protections for non-parties to avoid undue burden.
Federal vs. State Court Third-Party Subpoenas: Key Differences
Most guidance in this article focuses on federal court subpoenas under FRCP Rule 45, which applies uniformly across the US in federal cases. State courts have their own rules (often modeled after the federal rules), but timelines, procedures, and enforcement can differ significantly.
- Federal: Strict 14-day objection deadline; motions heard in the district where compliance is required.
- State: Varies (e.g., California allows objections up to the production date in some cases). Always check your state’s rules of civil procedure.
If your subpoena is from a state court, immediately review the issuing state’s equivalent to FRCP 45 or consult local counsel.
Timeline for Objecting to a Third-Party Subpoena
Timing is critical. Under FRCP 45(d)(2)(B), you must serve written objections before the earlier of:
- The date and time specified for compliance in the subpoena, or
- 14 days after the subpoena was served on you.
Missing this deadline typically waives your objections. If the subpoena demands testimony (deposition, hearing, or trial), written objections alone may not suffice—you often need to file a motion to quash.
Pro tip: Calendar the deadline immediately and request a reasonable extension in writing from the issuing party while you review the subpoena.
Valid Grounds for Objecting to a Third-Party Subpoena
Courts protect non-parties from overreaching. Strong grounds for objection include:
- Undue burden or expense (most common)
- Lack of relevance to the claims or defenses in the case
- Overly broad, vague, or ambiguous requests
- Privilege (attorney-client, work-product, trade secrets, or other protected matter)
- Insufficient time to comply
- Geographic limits exceeded (generally must be within 100 miles of your residence, employment, or regular business location for production)
- Failure to tender witness fees (for testimony subpoenas)
FRCP 45(d)(1) requires the issuing party to take reasonable steps to avoid imposing undue burden or expense, and courts must enforce this with sanctions if violated.
How to File Written Objections to a Third-Party Subpoena (Step-by-Step)?
- Review the subpoena thoroughly — Identify every request and assess potential objections.
- Consult an attorney — Do not attempt this alone if the request involves sensitive data.
- Draft written objections — Clearly state the basis for each objection (e.g., “Request No. 3 is overly broad and seeks irrelevant information not proportional to the needs of the case”).
- Serve the objections — Send them to the attorney or party designated in the subpoena (via email, mail, or hand delivery as allowed by FRCP 5(b)). You do not need to file them with the court unless responding to a motion.
- Retain proof of service — Keep a dated copy and proof that it was timely served.
Once you serve timely written objections, you are generally excused from complying until the court orders otherwise. The burden then shifts to the issuing party to file a motion to compel in the proper district court.
When to File a Motion to Quash or Modify Instead?
Written objections work for document/inspection subpoenas. For subpoenas commanding testimony, or when you want to completely block production, file a motion to quash or modify under FRCP 45(d)(3) in the district where compliance is required.
Mandatory quash/modify grounds:
- No reasonable time to comply
- Exceeds geographic limits
- Requires privileged material
- Subjects you to undue burden
Courts may also quash for trade-secret protection or unretained expert opinions.
Sample Structure for a Third-Party Subpoena Objection
A professional objection typically includes:
- Case caption and subpoena details
- General objections (e.g., undue burden, relevance)
- Specific objections to each request
- Statement reserving all rights
- Signature by you or your attorney
Numerous templates exist online, but tailor them to your facts and have counsel review them.
Protecting Privileged or Confidential Information
If responsive materials contain privileged information, you must:
- Explicitly claim the privilege
- Provide a privilege log describing the withheld items without revealing protected details (FRCP 45(e)(2))
For trade secrets or proprietary data, request a protective order or ask the court to quash/modify under FRCP 45(d)(3)(B).
Cost-Shifting and Expense Protection for Third Parties
FRCP 45(d)(2)(B)(ii) requires any court order compelling production to protect a non-party from significant expense resulting from compliance. Courts frequently shift reasonable costs (including attorney fees and e-discovery expenses) to the issuing party when the burden on the third party is substantial.
Document all time and costs incurred in responding or objecting.
What Happens After You Object?
- The issuing party may negotiate a narrowed scope
- They may file a motion to compel (you then respond)
- The court decides whether to enforce, modify, or quash the subpoena
- If you lose and still refuse to comply, you risk contempt sanctions
Common Mistakes to Avoid When Objecting to a Third-Party Subpoena
- Waiting past the 14-day (or compliance) deadline
- Producing documents before objecting
- Ignoring geographic or service defects
- Failing to preserve ESI (issue a litigation hold immediately)
- Assuming state rules match federal rules exactly
Frequently Asked Questions About Objecting to Third-Party Subpoenas
Can I ignore a third-party subpoena?
No—timely objection or compliance is required to avoid contempt.
Does the subpoena have to come from the court where I live?
No, but compliance location is limited by FRCP 45(c).
What if the subpoena asks for ESI?
You may object to the form of production and are protected from producing inaccessible data without good cause shown by the requesting party.
How much does it cost to object?
Attorney fees vary widely; early intervention is usually far cheaper than full compliance or motion practice.
Final Tips and Next Steps
Receiving a third-party subpoena can feel overwhelming, but FRCP Rule 45 gives non-parties strong protections. Act quickly, document everything, and prioritize protecting privileged or confidential information.
Recommended immediate action:
- Contact an experienced litigation attorney in your jurisdiction today.
- Preserve all potentially responsive documents and ESI.
- Serve written objections within the deadline if grounds exist.
By following this guide and working with counsel, you can effectively object to a third-party subpoena while minimizing disruption to your business or personal life. For jurisdiction-specific advice, search your state’s rules of civil procedure or consult a local attorney promptly.
