A federal grand jury can subpoena documents and witnesses, hear evidence in secret, and return an indictment. If you are a target, subject, or witness, your rights and obligations differ—and mistakes in testimony or document production can have serious consequences. In the Southern District of Florida, indictments are filed in federal court in Miami and other divisions.
We advise clients through grand jury investigations, negotiate with prosecutors when appropriate, and defend clients after indictment in federal court.
What Happens in a Federal Grand Jury Investigation?
A grand jury hears evidence presented by prosecutors and may return an indictment if it finds probable cause. Targets may not know the full scope of the investigation. Subpoenas can require documents or testimony, subject to privileges and motions to quash or limit when the law allows.
- Investigation and subpoenas
- Indictment or declination
- Initial appearance and arraignment
- Discovery and pretrial litigation
Grand Jury Subpoenas and Testimony
Responding to subpoenas requires careful review of privilege, relevance, and burden. Testimony is under oath and can be used in later proceedings. We coordinate with clients facing investigation alongside our Miami federal criminal defense team.
What is the difference between a target and a witness?
A target is likely to be charged; a witness may have information without being accused. Status can change as the investigation develops. Your lawyer can help interpret government communications cautiously.
Can grand jury proceedings be challenged?
In some cases, motions may address improper grand jury conduct or overbroad subpoenas. Whether a motion fits depends on the record and the law.
How soon after an indictment do I appear in court?
Federal defendants typically have an initial appearance and arraignment shortly after arrest or summons. Timing depends on how you are brought into the case.
After an Indictment Is Filed
Once indicted, the case moves to pretrial litigation in U.S. District Court. See our overview of the federal indictment process and how it differs from state court.
Defense Strategy
Strategy may include pretrial motions, challenging evidence, and sentencing advocacy. Co-defendants and voluminous discovery are common in federal cases.
