Running an online business means handling customer and user data, and most days, this is part of daily operations. However, when you receive a subpoena demanding access to that data, it can feel unsettling at first. You may have many questions running through your head: Do you have to comply? What data can you safely share? What happens if you get it wrong? Understanding how subpoenas work and what to do when you receive one can protect your business while staying on the right side of the law.

What is a Subpoena?

A subpoena is a legal document, issued by a court, attorney, or government agency, requiring the production of evidence or testimony. In the context of user data, subpoenas are usually sent because information a business holds may be relevant to an investigation or lawsuit. Some of the most common reasons for receiving a subpoena include:

Disputes between users

Fraud investigations

Intellectual property claims

Employment disputes

A criminal investigation where user activity is being examined.

Subpoenas generally fall under two categories. One type asks someone from your business to show up and testify under oath, while the other requires you to turn over records, such as account details, IP logs, communications, or transaction history. Regardless of the type of subpoena you receive, it should clearly state what is being requested and provide a deadline. While a deadline is essential, it does not mean you should rush to comply without proper review.

Steps to Take When You Receive a Subpoena

The first thing you should do is read the document carefully. Look at who issued the subpoena and what jurisdiction it applies to. Some subpoenas are valid and enforceable, while others may be overly broad or even improperly served.

Next, identify what data is being requested. Subpoenas for user data may range from basic account information to messages, IP logs, or payment records.

Then, check your privacy policy and terms of service. These documents often outline how and when user data may be disclosed. If your policies promise notice to users before disclosure, or limit disclosures to legally valid requests, such commitments have to be considered. Unless the subpoena specifically prohibits notice to users, you may have to notify them before releasing their data.

You should also consider whether the subpoena can be challenged. If the request is too broad, seeks irrelevant information, conflicts with privacy laws, seeks documents that contain sensitive business information or trade secrets, or imposes undue burden or expense, you may be able to object, file a motion to quash, or reduce its scope. This is especially vital when a subpoena requests a large volume of data or sensitive user information.

Another critical step is preserving the data in question. Once you receive a subpoena, you should maintain the requested data and suspend any routine deletion practices for anything relevant. Failing to preserve data after receiving a subpoena can create legal problems, even if the deletion was unintentional.

Finally, when you do respond, provide only what is requested. Don’t alter records, omit information, or try to “clean up” data before producing it. Getting legal guidance here is essential to ensure you comply with the subpoena and protect any privileged documents.

Types of Legal Process: Grand Jury Subpoenas, Administrative Subpoenas, and Civil Subpoenas

Not all subpoenas carry the same weight or procedural posture. A grand jury subpoena is issued in the context of a federal criminal investigation and demands production to a grand jury. These are among the most serious demands your business can receive, carry the highest risk of contempt sanctions for non-compliance, and often trigger strict obligations under federal secrecy rules—you may not be permitted to disclose to affected users that a grand jury subpoena has been served. An administrative subpoena is issued by a federal agency pursuant to statutory authority without prior court approval; the FTC, SEC, CFTC, and other agencies use these regularly. A civil subpoena is issued in connection with ongoing civil litigation and must comply with the Federal Rules of Civil Procedure or the applicable state rules. The legal analysis for challenging scope, seeking protective orders, and deciding when to notify affected users differs substantially across these categories.

The Stored Communications Act and What You Are Required to Disclose

The Stored Communications Act (SCA), 18 U.S.C. §§ 2701–2713, governs the disclosure of electronic communications and customer records held by electronic communication service (ECS) and remote computing service (RCS) providers. The SCA prohibits disclosure of the contents of stored communications in response to a civil subpoena—only a warrant obtained under the Electronic Communications Privacy Act, or in certain cases a court order or user consent, authorizes disclosure of content. Basic subscriber information (name, address, billing records, IP logs, session data) may be disclosed in response to a civil or administrative subpoena. Understanding the SCA categories is essential: disclosing content in response to a civil subpoena that does not authorize such disclosure exposes the business to SCA civil liability under § 2707, including statutory damages of $1,000 per violation.

User Notification: When Is It Required, and When Is It Prohibited?

Your privacy policy likely represents to users the circumstances under which their data may be disclosed to third parties. If your policy promises advance notification before disclosures, you have a contractual obligation to honor that commitment. However, many subpoenas—particularly those in criminal investigations—include a non-disclosure order (NDO) under 18 U.S.C. § 2705(b), prohibiting you from informing the user that their data is being sought. Violating an NDO is a federal crime. Conversely, notifying a user when no NDO is present gives them the opportunity to seek their own legal counsel and contest the subpoena, which can protect your relationship with your users and may result in the scope being narrowed. The decision requires legal judgment on a case-by-case basis.

Motions to Quash, Modify, or Obtain a Protective Order

A subpoena that is overly broad, imposes undue burden, seeks irrelevant information, or conflicts with applicable privilege can be challenged. For a civil subpoena, you may move to quash or modify it in the court where the subpoena was issued, under Fed. R. Civ. P. 45(d)(3) or the equivalent state rule. Grounds for quashing include: the subpoena fails to allow reasonable time for compliance; the commanded disclosure conflicts with a privilege or legal protection; the subpoena subjects the recipient to undue burden; or the subpoena seeks electronic communications that the SCA prohibits disclosing in response to a civil subpoena. A protective order may also be sought to restrict how produced information can be used—particularly important when the data involves the personal information of individuals not parties to the litigation.

Building a Legal Hold and Data Preservation Process

Once your business becomes aware of anticipated or actual litigation, an obligation to preserve potentially relevant data arises. Failure to preserve data after the duty to preserve has been triggered—known as spoliation—can result in severe sanctions under Fed. R. Civ. P. 37(e), including adverse inference instructions at trial, dismissal of claims or defenses, or fee awards. A legal hold is the formal process by which your business suspends routine document destruction and ensures that relevant data is preserved. It should cover all potentially relevant custodians, data types (including emails, messaging apps, server logs, and user records), and time periods identified by the subpoena or litigation hold notice.

International Subpoenas and Cross-Border Data Transfer Obligations

Online businesses with users in the European Union face additional complexity when a U.S. subpoena demands production of data belonging to EU residents. The GDPR, Regulation (EU) 2016/679, generally prohibits the transfer of personal data outside the EU except under specific authorized mechanisms (Standard Contractual Clauses, adequacy decisions, etc.), and Article 48 specifically addresses the circumstances under which a transfer may be required by a foreign court or tribunal. In the absence of an international data sharing agreement, producing EU user data in response to a U.S. subpoena without satisfying GDPR requirements can expose your business to regulatory action by EU data protection authorities.
