You Got a Grand Jury Subpoena. What Happens Next Determines Everything.
A grand jury investigation is not a formality — it is a prosecutorial process designed to build a case against someone. If you have received a subpoena or a target letter, you are already inside that process. What you say, what you produce, and whether you testify are decisions that can end in an indictment or walk you out the door. I have spent more than 30 years navigating grand jury proceedings in New York, and I can tell you this: the time to get a lawyer is before you respond to anything.

What a Grand Jury Subpoena Actually Means for You
A subpoena is a legal command. You are required to appear, produce documents, or both — and ignoring it is not an option. But complying without counsel is a serious mistake. Before you hand over a single document or say a single word, you need to understand what prosecutors are looking for and whether you are a witness, a subject, or a target of the investigation.
These distinctions carry very different legal weight:
Witness:
You have information relevant to the investigation. You are not currently under suspicion, but that status can shift based on what you say.
Subject:
Your conduct falls within the scope of the investigation. You are not yet charged, but prosecutors are watching you closely.
Target:
Prosecutors have substantial evidence linking you to a crime. An indictment is the likely next step if you
are not represented aggressively right now.
If you have received a target letter, treat it as the equivalent of an arrest that has not happened yet.
Do You Have to Testify Before a Grand Jury?
The short answer is no — not without understanding your rights first. The Fifth Amendment protects you from being compelled to give testimony that could incriminate you. Whether invoking that right makes sense in your specific situation depends on the nature of the investigation, what prosecutors already have, and what immunity, if any, is on the table.
I evaluate every grand jury situation on its facts before advising a client to say anything. Sometimes the right move is to appear and assert your rights. Sometimes the right move is to negotiate. Sometimes there is a path to immunity that removes your exposure entirely. There is no universal answer — but there is always a wrong move, and that wrong move is walking into a grand jury room without counsel who knows exactly what is happening on the other side of that proceeding.

How I Defend Clients in Grand Jury Proceedings
Grand jury proceedings in New York are one-sided by design. Prosecutors present evidence, witnesses testify, and there is no judge to rule on objections. The target has no right to be present. That asymmetry is exactly why experienced representation outside that room matters so much.
Step 1:
Immediate Case Assessment
The moment you contact me, I review every document you have received — the subpoena, the target letter, any prior communications from law enforcement — and identify where you stand in the investigation. I tell you directly what your exposure looks like and what the realistic outcomes are.
Step 2:
Strategic Response Planning
Before you respond to anything, I map out every option: asserting Fifth Amendment rights, negotiating with prosecutors, pursuing immunity, or challenging the scope of the subpoena itself. The response strategy is built around your specific facts — not a template.
Step 3:
Witness Preparation
If testifying is the right call, I prepare you for exactly what will be asked, how prosecutors are likely to frame their questions, and how to answer accurately without expanding the scope of your exposure. Preparation is not coaching you to lie — it is making sure you do not accidentally say more than you need to.
Step 4:
Active Monitoring and Intervention
I maintain direct working relationships with prosecutors and court personnel across New York. While I cannot enter the grand jury room with you, I am positioned outside it throughout your testimony and available to confer with you between questions. If the investigation escalates toward indictment, I am already in motion.
Why Grand Jury Experience Is Not Interchangeable
Grand jury defense requires a specific kind of institutional knowledge. You need a lawyer who understands how New York prosecutors build their cases before an indictment, not just after. I have spent three decades on the criminal defense side of that process — not in a mixed practice that handles divorces and contracts alongside criminal matters. Criminal defense is the only work I do.
I teach criminal law and procedure as an adjunct professor at New York University and St. John's University. I have published in the New York Law Journal. That depth of knowledge is not incidental — it shapes how I analyze a grand jury investigation and how I communicate your options to you.
Frequently Asked Questions About Grand Jury Investigations in New York
What should I do if I receive a grand jury subpoena in New York?
Call a criminal defense attorney before you respond to anything. A subpoena requires a response, but it does not require you to testify or produce documents without first understanding your legal position. The steps you take in the first 24 to 48 hours can determine whether you are indicted.
What is a target letter and how serious is it?
A target letter is a written notice from a prosecutor or federal agency informing you that you are a target of a grand jury investigation — meaning prosecutors believe they have substantial evidence connecting you to a crime. It is one of the most serious pre-charge communications you can receive. If you have received one, you need a lawyer immediately.
Can I refuse to testify before a grand jury?
You have a Fifth Amendment right against self-incrimination, which means you can decline to answer questions that could be used against you. Whether and how to invoke that right depends on your specific situation. A prosecutor may also offer immunity in exchange for testimony, which changes the calculus significantly. This is not a decision to make without counsel.
What is the difference between a grand jury subpoena and an indictment?
A subpoena is a demand to appear or produce evidence as part of an ongoing investigation. An indictment is the formal charge that results if the grand jury finds probable cause to believe a crime was committed. A subpoena means the investigation is active. An indictment means charges have been filed and prosecution begins.
Does Glenn Hardy handle federal grand jury investigations?
Yes. I represent clients in federal grand jury proceedings in both the Eastern District of New York and the Southern District of New York, as well as in any U.S. federal court. Federal investigations carry distinct procedural rules and often involve agencies like the FBI, DEA, or IRS — experience in that environment is not optional.
A Grand Jury Investigation Has a Clock. So Does Your Window to Respond.
If you have received a subpoena or a target letter, the investigation is already underway. Every day without counsel is a day prosecutors are working without opposition. I answer my phone directly — not a receptionist, not a paralegal. Call me now, tell me what you received, and I will tell you exactly where you stand.
