Receiving a federal grand jury subpoena can be frightening. It often means that the federal government is investigating a serious criminal matter — and you or your business may have information they want. Whether you are a witness, subject, or target, how you respond will have a major impact on your legal future.
Below, we break down the top 7 tips to follow if you receive a federal grand jury subpoena, along with answers to common questions and how a federal criminal defense attorney can guide you through this complex process.
A subpoena doesn’t necessarily mean you are accused of a crime, but it does require your immediate attention. Federal subpoenas are formal orders that must be obeyed.
Failure to comply can lead to contempt of court charges, fines, or even arrest. Never ignore a subpoena — instead, contact a qualified attorney as soon as you receive it.
There are two main types of federal grand jury subpoenas
Your attorney will review the subpoena to determine its scope, validity, and deadlines, and ensure that any required information is produced lawfully and strategically.
The most important step you can take is to hire a federal criminal defense lawyer immediately. Federal cases are handled by agencies like the FBI, DEA, IRS, or DOJ, and the procedures are highly technical.
A skilled defense attorney can:
Having a lawyer handle communications ensures you don’t make statements that could later be used against you.
Once you receive a subpoena, you are legally obligated to preserve all documents, files, and electronic data that may be relevant. Do not delete, alter, or destroy any records — doing so can result in obstruction of justice charges.
Your attorney can help coordinate a lawful evidence preservation plan and oversee compliance to ensure you stay within the law.
Many subpoenas request broad sets of documents that could include:
Your lawyer will conduct a privilege review to ensure protected materials are not disclosed. This process prevents you from accidentally waiving attorney–client privilege or exposing sensitive business information.
Never communicate directly with investigators or prosecutors listed on the subpoena.
Federal agents are trained to ask questions that may elicit incriminating statements, even unintentionally.
All communication should go through your attorney, who will handle inquiries, negotiate deadlines, and ensure your statements are legally safe and accurate.
If you are required to testify before the grand jury, your attorney will prepare you by:
While your attorney cannot enter the grand jury room, they will be your strategic partner outside the door, ensuring you are protected at every stage.
1. What is a federal grand jury subpoena?
It’s a formal legal document requiring you to testify or produce evidence before a federal grand jury investigating potential criminal activity. It’s issued by the Department of Justice under federal court authority.
2. Am I in trouble if I receive one?
Not necessarily. You may be a witness (with relevant information), a subject (someone whose actions are under review), or a target (someone suspected of wrongdoing). Your attorney can clarify your status with prosecutors.
3. What happens if I ignore it?
Ignoring a subpoena can result in contempt of court, fines, or jail time. The safest approach is to immediately consult a federal defense lawyer and follow their guidance.
4. Can my lawyer negotiate with the government?
Yes. Your attorney can negotiate deadlines, narrow the scope, or request that certain documents be excluded due to privilege or irrelevance.
5. Can I refuse to testify?
You can invoke your Fifth Amendment right against self-incrimination under certain circumstances. Your lawyer will advise when this is appropriate and how to assert it correctly.
An experienced federal criminal defense attorney provides more than legal advice — they offer protection, strategy, and peace of mind during an overwhelming process.

Federal grand jury proceedings can be unpredictable, but with an experienced attorney’s guidance, you can navigate them strategically and safely.
