Receiving a federal grand jury subpoena can be unsettling, especially when the document requests records, testimony, or information about another person or organization. A subpoena is a legal demand that deserves careful attention, but receiving one does not by itself mean that you have been charged with a crime or that you are the subject of the investigation.
The safest first step is to preserve the subpoena and obtain advice about the specific request before producing documents or answering questions. Federal investigations can involve overlapping issues such as privilege, confidentiality, self-incrimination, electronic records, and the scope of the demand. The right response depends on the language of the subpoena and the facts surrounding it.
What a Federal Grand Jury Subpoena Does
A federal grand jury helps determine whether criminal charges should be brought. It may hear testimony and review documents gathered by federal prosecutors and investigators. The Department of Justice explains how federal grand juries investigate possible federal offenses and may return an indictment when the legal requirements are met. A subpoena can be directed to a witness, a business, a records custodian, or someone who may have information relevant to the investigation.
The subpoena may require attendance at a specified time, testimony before the grand jury, production of identified records, or a combination of these obligations. It may also include instructions about formatting, delivery, confidentiality, and the date by which a response is required. Do not assume that a request is optional simply because you have not been accused of wrongdoing.

Read the Request Before Responding
Keep the original subpoena, every attachment, the envelope or delivery information, and any cover letter together. Read the definitions, date ranges, categories of documents, production instructions, and contact information. A request for “all communications,” for example, may raise different questions from a request limited to a particular transaction, account, employee, or time period.
Do not delete, alter, backdate, or rewrite records after receiving the subpoena. Preserve relevant email, text messages, cloud files, accounting records, access logs, and device data in their original form. If the records are held by a company, the organization should use a controlled preservation process that identifies custodians and prevents routine deletion from removing potentially relevant information.
Understand Whether You Are a Witness, Subject, or Target
A person may receive a subpoena because they witnessed events, possess records, work for an organization, or have information about another person. Those circumstances do not answer the separate question of how prosecutors view that person’s potential involvement. Counsel can help evaluate whether the subpoena suggests a witness role, a subject role, or a target role, although the government may not provide a formal label in every situation.
This distinction matters because a response that seems helpful in the moment can create problems if the requested information also concerns your own conduct. Before an interview or grand jury appearance, review the facts, documents, possible privileges, and any risk that an answer could be inaccurate, incomplete, or self-incriminating.
Consider Privilege and Confidential Information
Some requested materials may involve attorney-client communications, work product, medical information, trade secrets, personal data, or other protected interests. Privilege is fact-specific and can be affected by who received a communication, why it was created, and whether it was shared with others. Do not decide that a document is privileged—or waive a privilege—without examining the circumstances carefully.
Businesses should also consider whether a response contains confidential customer information, protected health information, financial records, or information belonging to employees or third parties. A lawyer can help identify an appropriate production method, negotiate reasonable limits where appropriate, and document any objections or privilege decisions.
Do Not Alter the Records or Contact Other Witnesses About Their Answers
Preservation is different from reconstruction. Keep records as they existed, maintain a clear copy of the subpoena, and document the steps taken to collect responsive material. Avoid coaching another person’s testimony, coordinating accounts, or asking someone to change a record. Communications about the investigation may themselves become relevant, so limit discussion to people who need the information for a legitimate reason.

Review the Deadline and Scope
A subpoena should be reviewed for the required date, location, custodian, categories of information, and method of production. If the deadline is unrealistic, the request is unclear, or compliance would impose an unreasonable burden, counsel may communicate with the issuing attorney or consider whether a formal objection or court request is appropriate. Ignoring the subpoena is not a reliable strategy; a court may have authority to address noncompliance.
Federal Rule of Criminal Procedure 17 governs subpoenas in federal criminal proceedings. The United States Courts maintain the current rules, and the Department of Justice’s Justice Manual provides additional information about grand jury practice. These sources are useful starting points, but they do not replace advice about a particular subpoena or investigation.
Prepare for Testimony Carefully
If testimony is required, review the subject matter and relevant records with counsel beforehand. Answer the question asked, do not guess, and ask for clarification when a question is unclear. A witness should not speculate or fill silence with information that was not requested. If a question raises a privilege or self-incrimination concern, pause and obtain legal guidance before answering.
When to Contact Federal Criminal Defense Counsel
Consider obtaining counsel before responding to a federal grand jury subpoena, particularly when the request concerns your own conduct, a business you manage, financial transactions, electronic communications, healthcare records, or another person who is already under investigation. Early review can help identify preservation obligations, clarify the scope of the demand, and reduce the risk of an incomplete or inconsistent response.
