About the Jury Process


California law requires a fair cross-section of each county's qualified residents to be available each day for jury duty. The selection of persons for jury service is accomplished by randomly drawing names from the list of registered voters and the Department of Motor Vehicles driver's license and identification card list for the County of San Mateo. Random summoning enhances juror impartiality.


You have been randomly selected by computer to serve as a trial juror. The list of persons provided by the DMV and Voter's Registration shall be considered inclusive of a representative cross section of the population. The jury commissioner shall not disclose the information furnished by the Department of Motor Vehicles or list of registered voters, to any person, organization, or agency.

Because we pull information from two agencies, if you are known by one name with the DMV and a different name with Voter's Registration, the system will count you as two different people. For instance, at the DMV if your license reads "John Andrew Smith" and with Voter's Registration you register as "John A. Smith", the system will think you are two different people.

Additionally, the same will occur if you have two different addresses at DMV and Voters Registration: for instance if you have a PO Box with the DMV and a street address with Voters Registration.

To correct this duplication contact DMV or Registrar of Voters as appropriate:


All persons are eligible and qualified to be prospective trials jurors, except the following:

  • Persons who are not citizens of the United States.
  • Persons less than 18 years of age.
  • Persons not living in the State of California.
  • Persons who are not residents of San Mateo County.
  • Persons convicted of malfeasance in office or a felony, and whose civil rights have not been restored.
  • Persons who do not possess sufficient knowledge of the English language are not automatically exempted from jury duty. The judiciary will make the decision to either grant or deny this exemption. No person shall be deemed incompetent solely because of the loss of sight, hearing or other disability.
  • Persons serving as grand or trial jurors in any court of this state.
  • Persons who are the subject of conservatorship.
  • Persons who are peace officers as defined in Penal Code §830.1 or §830.2(a).

No person shall be excluded from eligibility for jury service in the State of California, for any reason other than those reasons provided by this section. Eligibility Period: If qualified, your period of eligibility will be for the appearance date listed on your summons (possibly including a second day) or the duration of one trial, if selected.


San Mateo Superior Court operates on a One Day/One Trial system.

In order to minimize the number of jurors who must appear in person, the Court uses the standby process. You are required to check the reporting instructions for at least one day or until instructed that your service is completed.

If you are instructed to report to the courthouse, you may or may not be selected to serve as a juror on a trial. The court is required to have a sufficient amount of jurors available for all anticipated trials. The jury staff tries to carefully estimate the number of jurors needed, but there are many variables outside their control.

If you are selected to serve on a trial as a sworn juror, the term of service will be the length of the trial. Trials vary in length. You will be informed by the judge assigned to the trial.

If you are not selected to serve by the end of your first day and the judge has not ordered you to return for another day of selection, your jury service is considered completed.


In accordance with California Civil Procedures, Section 215, jurors appearing for more than one day will receive $15.00 per day and mileage compensation at a rate of 34 cents per mile. Mileage is based on one way only from your city of residence to the specific court location. Payment begins on the second day.


Certification of your appearance for jury duty is required by some employers and will be furnished to you by a jury clerk if requested.


Employers cannot discriminate against employees serving jury duty. Employers must allow employees time to serve as a juror.

The California Labor Code prevents any employer from firing or harassing an employee who is summoned for jury service. However, you must let your employer know well in advance, as soon as you receive your summons. You should contact the court if you have a problem with your employer. Remember that you can postpone jury service to a more convenient time.

TTY devices are available court wide. For TTY service, call 650-261-5002. The staff member will determine which division is best suited to handle the purpose of your call and will transfer you to the appropriate court division.
