How Often Can You Be Called for Jury Duty in California?

In California, once you report for jury service or serve on a trial, you cannot be summoned again for at least 12 months. That single rule is the answer to how often you can be called for jury duty in California, and it applies whether you spent a full day in the assembly room without being seated or sat through a weeks-long trial.¹

When the 12-Month Clock Starts

California uses a “one day or one trial” system. You report to the courthouse on the date printed on your summons, wait in the jury assembly room, and one of two things happens. If no trial needs you that day, you go home and your obligation is done. If you are placed on a jury, your service lasts through the end of that trial, and completing it satisfies your duty.¹

Either way, the 12-month protection kicks in from that service date. Many courts let you call in or check online the night before your reporting date, and if no trials need jurors, you may never have to appear at all. That call-in or online check-in still counts as fulfilling your summons for the year.¹

Most trials wrap up within a week, but complex civil or criminal cases can run longer. However long yours runs, finishing it locks in your 12 months.

If You Get Summoned Too Soon

Courts pull juror names from voter registration and DMV lists, and those lists don’t always reflect who served recently. If a summons arrives and you believe you served within the past year, contact the jury commissioner’s office listed on the summons. You may need to provide the prior service date or a certificate of completion. The summons itself usually explains how to claim recent service as a basis for excusal.

Keep whatever documentation the court gives you when you finish service. A completion certificate, a discharge slip, or a stamped juror badge is the simplest way to show you’re inside the 12-month window.

Federal Jury Duty Runs on a Separate Clock

Serving on a California state jury does not protect you from a federal jury summons, and vice versa. The two court systems maintain separate juror pools and separate frequency rules.

The federal rule is longer than the state’s. Under 28 U.S.C. § 1866, no person can be required to serve or attend for prospective federal petit jury service for more than 30 days in any two-year period, unless a particular trial they’re on runs longer.²

If you receive a state and a federal summons close together, contact the jury commissioner for whichever one arrived second and explain the overlap. Courts routinely accommodate this.

What Happens If You Skip a Summons

Ignoring a summons doesn’t reduce how often you get called; it increases the trouble. Under Code of Civil Procedure Section 209, the process escalates in steps.

If you fail to appear for your first summons, the court can issue a second summons no sooner than 90 days later, and it will note that you already missed one. Ignore that, and the court sends a failure-to-appear notice warning that fines may follow. If you still don’t respond, the court issues an order to show cause, requiring you to appear and explain.³

Monetary sanctions cap at $250 for a first violation, $750 for a second, and $1,500 for a third or subsequent violation. The court can also hold you in contempt, which carries the possibility of additional fines and jail time. Paying a fine doesn’t discharge the underlying duty; you still owe the service.³

Who Can Be Called in the First Place

The 12-month cap only matters if you’re eligible to be summoned at all. Under Code of Civil Procedure Section 203, you qualify as a California juror if you are a U.S. citizen, at least 18, a resident of the county that issued the summons, and able to understand English well enough to follow testimony and deliberate. A physical disability such as hearing loss does not automatically disqualify you.⁴

Section 203 also lists who cannot serve: people currently incarcerated in any jail or prison, people on parole, post-release community supervision, felony probation, or mandated supervision for a felony conviction, anyone already serving as a grand or trial juror in a California court, and people subject to a conservatorship.⁴

No occupation exempts you. California has eliminated all occupation-based exemptions, so doctors, lawyers, teachers, and elected officials all remain in the pool.⁵

Postponing Instead of Fighting the Summons

If the timing is bad but you’re not inside the 12-month window, a postponement is usually easier than an excusal. Most California courts let you defer online or by phone using the information printed on your summons. You can typically choose a new date within a set future window. The number of postponements allowed varies by county; some courts grant one deferral for any reason, others allow up to two before you have to appear. Check your summons or the court’s website for local rules.

A postponement doesn’t extend the 12-month protection. That clock only starts once you actually complete service.

Permanent Medical Excusal

If a chronic or permanent condition makes jury service impossible for you, you can request a permanent medical excusal with a written statement from a treating healthcare provider explaining the condition and why it prevents you from serving. Courts handle these requests under California Rules of Court, Rule 2.1009. Once granted, you will not receive future summonses.⁶
