Legal Question in Administrative Law in California

In order to be subject to jury duty, you must be a resident of the area served by the court. See Code of Civil Procedure section 197. The jury commissioner for each court selects names of prospective jurors from lists which include, but are not limited to, DMV licensed driver lists, telephone directories, customer mailing lists, and utility company lists. Some people erroneously believe that prospective juror names are gleaned from voter registrations. This is possible, but not a predominant source.

As long as your name appears on such lists, you are more or less likely to be summoned for jury duty.

The summons is issued by mail, and if you have moved but have arranged for mail forwarding, there's no reason you shouldn't be made aware of a jury summons. If and when you receive one, simply notify the jury commissioner or deputy who sent the notice that you are now a resident of another jurisdiction, and therefore not qualified to serve.
