If you have been summoned, here is how long you serve on a grand jury: federal grand juries sit for a term of up to 18 months, which a judge can extend by another six months for a hard cap of two years. State grand juries run shorter, typically anywhere from a couple of weeks to about six months depending on where you live. The clock sounds heavier than it is, because grand juries don’t meet daily. Most convene one to a few days a week, and some weeks they don’t meet at all.
Federal Grand Jury Term Length
Every federal grand jury sits for a term of up to 18 months. The Federal Rules of Criminal Procedure set that timeline, and it applies the same way in every federal district.1Cornell Law School. Federal Rules of Criminal Procedure Rule 6 – Section: (g) Discharging the Grand Jury The term is long because federal investigations tend to be complex. A single panel may review evidence in dozens of unrelated matters during its service, and some of those investigations take months to develop.
When 18 months run out with an investigation still open, a federal judge can extend the panel for up to six more months, but only after finding that the extension serves the public interest.1Cornell Law School. Federal Rules of Criminal Procedure Rule 6 – Section: (g) Discharging the Grand Jury That brings the ceiling to 24 months for a regular federal grand jury. Extensions tend to happen when a jury is deep into a sprawling case and swapping in a fresh panel would waste months of work.
One outlier is worth flagging. A special grand jury, convened under a separate federal statute to investigate organized crime or public corruption, can serve for up to 36 months.2GovInfo. 18 USC 3331 Special grand juries are uncommon, and you would know before showing up if you had been called for one.
State Grand Jury Term Length
State terms are almost always shorter than federal ones. Duration runs from as little as two weeks in some jurisdictions to around six months in others, with many states landing somewhere in between. Each state’s statutes set the specific length, which often tracks the local prosecutor’s caseload. A densely populated county may empanel a grand jury for several months at a stretch; a rural county may need one for only a few weeks.
Not every state uses grand juries the same way. About half the states require grand jury indictments for serious felonies. The other half let prosecutors bring charges by filing a document called an information, which skips the grand jury entirely. The Fifth Amendment’s grand jury requirement applies only to federal prosecutions.3Congress.gov. Amdt5.2.2 Grand Jury Clause Doctrine and Practice Depending on where you live, a federal summons may be more likely than a state one.
As in the federal system, most states let a judge extend a grand jury’s term when an investigation needs more time. The request usually comes from the prosecutor or the grand jury foreperson, and the judge decides whether the circumstances justify keeping the panel together longer.
How Often You Actually Report During the Term
An 18-month term is not 18 months of daily courthouse visits. Grand juries meet only when the prosecutor has evidence to present, so the actual schedule is intermittent. A typical federal grand jury convenes one to three days a week, and some weeks have no sessions at all when the prosecutor’s cases aren’t ready.4United States Courts. Types of Juries State grand juries follow similar patterns, though frequency varies by jurisdiction and caseload.
On days you do report, sessions generally run during normal business hours. The prosecutor walks the panel through evidence, calls witnesses, and answers legal questions. Jurors then deliberate privately and vote on whether to issue an indictment. So while the term stretches over many months, the total number of days you actually spend at the courthouse is far smaller than the calendar span suggests.
Pay and Job Protection While You Serve
Federal grand jurors earn $50 for each day they actually attend. After 45 days of service, a judge can authorize an additional payment of up to $10 per day, bringing the maximum to $60.5Office of the Law Revision Counsel. 28 USC 1871 – Fees The federal government also reimburses mileage, tolls, and reasonable parking. If overnight travel is necessary, a subsistence allowance covers meals and lodging.
State pay varies widely. Daily stipends range from nothing in a couple of states to around $50 in the most generous ones, with the national average near $22. Some states raise the rate after a set number of days. Your summons or the court clerk’s office will confirm what your jurisdiction pays.
Federal law prohibits your employer from firing, threatening, or retaliating against you for serving on a grand jury in any federal court. If your employer breaks that rule, you can recover lost wages, get reinstated, and the employer faces a civil penalty of up to $5,000 per violation. When you return, you’re treated as if you had been on a leave of absence, with no loss of seniority or benefits.6Office of the Law Revision Counsel. 28 USC 1875 – Protection of Jurors Employment Virtually every state has a comparable law for state jury service. These protections don’t require your employer to pay you while you’re gone, though some do voluntarily.
Getting Excused or Postponing Service
Courts will consider excusing you or deferring your service, but not wanting to serve isn’t enough. Legitimate grounds include a medical condition that prevents participation, responsibility for someone who cannot be left without a caregiver, or financial hardship severe enough that serving would threaten your ability to cover basic living expenses.
The bar for financial hardship is higher than most people expect. Losing income during service doesn’t automatically qualify. Courts look for situations where the lost wages would create a genuine crisis, such as an inability to pay rent or feed dependents. You will typically need documentation, like tax returns, payroll records, or a physician’s statement.
Postponement is easier to get than a full excuse. Most courts let you defer to a later date, often within two to six months of the original summons. You can usually request one by phone, mail, or online using the instructions on your summons. A second deferral, after you have already postponed once, is much harder to obtain.
What Happens If You Ignore the Summons
A grand jury summons is a court order. Ignoring it puts you in contempt. Under federal law, anyone who fails to appear for jury service and cannot show a good reason faces a fine of up to $1,000, up to three days in jail, community service, or any combination of those penalties.7Office of the Law Revision Counsel. 28 USC 1866 – Selection and Summoning of Jury Panels
Enforcement usually starts with a show-cause order. The court directs you to appear before a judge and explain why you missed the summons. A valid reason, like a medical emergency or a summons you never received, will typically lead to rescheduling. Skipping the show-cause hearing, or offering an unconvincing excuse, can lead the court to issue a bench warrant. State penalties vary but follow the same escalating pattern.
In practice, courts try to resolve these situations without jail time. A juror who responds promptly after missing a date and offers a reasonable explanation will usually just be rescheduled. Serious penalties land on people who repeatedly ignore the court.
