If you or your business has received a subpoena connected to a Department of Justice investigation, the government is already gathering evidence in a federal matter that could carry criminal consequences. What you do next, and what you say or produce in response, can shape the trajectory of the entire case.

If federal agents have contacted you or you have received a federal DOJ subpoena, contact Evergreen Attorneys at (303) 948-1489 before responding or producing information.

Why a DOJ Subpoena Demands Immediate Attention

A subpoena from the Department of Justice is not a routine paperwork request. It signals that a federal investigation is active and that the government considers you, your company, or someone connected to you a source of evidence in a criminal investigation. The consequences of a misstep are serious: producing the wrong records can waive privilege, destroying or withholding responsive documents can trigger obstruction charges under statutes such as 18 U.S.C. § 1503, and failing to respond at all can lead to contempt proceedings in federal court.

The timeline for compliance is typically short: 10-21 days is common. Depending on the subpoena type, you may have days or weeks to respond, and every hour that passes without a legal strategy increases the risk of an unforced error that benefits the prosecution.

What Is a Department of Justice Subpoena?

A Department of Justice subpoena is a compulsory legal demand that requires a person or entity to produce documents, provide testimony, or both in connection with a federal investigation. DOJ subpoenas can arise in investigations involving federal fraud crimes, drug trafficking, health care fraud, public corruption, and virtually any other area of federal criminal law.

The term “DOJ subpoena” covers several distinct legal instruments, each governed by different rules. The type of subpoena determines the issuing authority, the scope of what the government can demand, and the available defenses. Understanding which subpoena you received is the first step toward building a lawful and strategic response.

Types of Federal Subpoenas the DOJ Uses

The Department of Justice does not rely on a single subpoena mechanism. Federal investigations use at least three primary categories, and the defense strategy must match the specific instrument.

Grand Jury Subpoenas

A grand jury subpoena is the most common tool in federal criminal investigations. It is issued under the authority of a sitting federal grand jury and can compel the production of documents (subpoena duces tecum) or require a witness to appear and testify (subpoena ad testificandum). Grand jury proceedings are conducted in secret under Justice Manual grand jury guidance, and recipients generally cannot disclose the subpoena’s contents without court permission. The scope of a federal grand jury subpoena defense often involves privilege assertions, motions to quash, and careful negotiation with the assigned Assistant United States Attorney.

Administrative Subpoenas

Certain federal statutes give the Department of Justice or specific agencies the power to issue administrative subpoenas without grand jury involvement. For example, 18 U.S.C. § 3486 authorizes administrative subpoenas in federal health care fraud investigations. These subpoenas can demand records, but they do not carry the same secrecy rules as grand jury process.

The enforcement mechanism for DOJ administrative subpoenas still runs through federal court: if you refuse to comply, the government can petition a judge to compel production.

Court-Issued Subpoenas

Under Federal Rule of Criminal Procedure 17, a federal court can issue subpoenas in pending criminal cases for documents or testimony. These subpoenas operate within the framework of an existing prosecution and are subject to the procedural rules governing federal criminal cases, including discovery obligations and constitutional protections.

Evergreen Attorneys won 9-0 in the U.S. Supreme Court in United States v. Hemani in June 2026, demonstrating the caliber of federal defense work the firm brings to high-stakes matters.

Related Investigative Tools

A DOJ subpoena may arrive alongside other federal investigative demands, including a civil investigative demand defense (CID) or a federal target letter representation. Each tool carries different obligations and risks, and receiving more than one at the same time often indicates the investigation is advanced.

How the Department of Justice Enforces Subpoena Compliance

The enforcement power behind a DOJ subpoena runs through the federal courts. If a recipient refuses to comply, the government can file a motion to compel in the appropriate U.S. District Court. A court that finds the subpoena valid and enforceable can hold the recipient in contempt, which may result in fines, sanctions, or even incarceration until compliance occurs.

Beyond contempt, there is a separate criminal risk. Intentionally destroying, altering, or concealing documents that are responsive to a federal subpoena can result in obstruction of justice charges. Federal document preservation duties attach the moment you know or reasonably should know that the government is seeking evidence. That duty can begin before you formally receive the subpoena if you are otherwise aware of the investigation.

What to Do After Receiving a DOJ Subpoena

The steps you take in the first hours and days after receiving a federal subpoena are critical. Follow this sequence:

1. Preserve everything. Immediately issue a litigation hold across your organization. Suspend any routine document-destruction policies. The federal document preservation duty is absolute once you are on notice of a government investigation, and violations can create independent criminal exposure.
2. Do not contact the government without counsel. Any statement you make to federal agents or prosecutors can be used in the investigation. Even informal conversations carry legal risk.
3. Identify the subpoena type and issuing authority. Determine whether you received a grand jury subpoena, an administrative subpoena, or a court-issued subpoena. The type dictates your legal options and deadlines.
4. Retain experienced federal criminal defense counsel. A lawyer who regularly handles DOJ subpoena defense strategies can evaluate the subpoena’s scope, identify privilege issues, assess constitutional and statutory objections, and negotiate with the government before you produce a single document.
5. Assess privilege and work-product protections. Attorney-client privilege, the work-product doctrine, and in some cases the Fifth Amendment may protect certain materials from production. These protections must be asserted properly and promptly; waiver can be inadvertent and irreversible.
6. Evaluate whether to move to quash or modify. Quashing a federal investigative subpoena is possible when the subpoena is overbroad, unduly burdensome, or seeks privileged material. Your counsel can file a motion to quash or negotiate a narrower scope with the government.

Frequently Asked Questions

Can the Department of Justice subpoena records without filing criminal charges?

Yes. The Department of Justice can use subpoena authority during pre-charge investigations, including grand jury matters and certain administrative investigations authorized by statutes such as 18 U.S.C. § 3486. Receiving a subpoena does not mean charges have been filed, but it does mean the government is actively seeking evidence in a federal matter. The pre-charge stage is often the most consequential phase of a federal case because the decisions made during this period can determine whether charges are ever brought.

How is a grand jury subpoena different from an administrative subpoena?

A grand jury subpoena is issued under the authority of a federal grand jury conducting a criminal investigation, while an administrative subpoena is issued under a specific statute that gives an agency or department the power to demand records in a defined category of investigations. The source of authority, scope, secrecy requirements, and enforcement rules differ between the two. Under Fed. R. Crim. P. 17 and statutes such as 18 U.S.C. § 3486, the governing framework depends entirely on the issuing authority (which rule they choose to use). That distinction controls the available defense strategies.

What happens if I do not respond to a DOJ subpoena?

Ignoring a federal subpoena can expose the recipient to enforcement proceedings and contempt sanctions. The government may petition a federal court to compel compliance, and the court can impose fines or other penalties if the subpoena is enforceable and the recipient still refuses. Separately, destroying or concealing responsive documents can create obstruction of justice exposure under 18 U.S.C. § 1503. A prompt legal review is essential because objections, privilege claims, and motion practice may change the response deadline and scope.

When should a person or business involve federal defense counsel after receiving a DOJ subpoena?

Immediately. The response clock begins running as soon as the subpoena is served, and preservation obligations may attach even earlier. Federal defense counsel can evaluate the subpoena, assert applicable privileges before any inadvertent waiver, negotiate scope and timing with the government, and protect against the risk of self-incrimination or obstruction. Waiting to retain counsel, even by a few days, can eliminate defense options that would otherwise be available.
