With two exceptions, service of process must be made within the boundaries of the State of California. The following kinds of defendants need not be served within the state:
A non-resident defendant who owns real property in California — if the defendant has no agent for service of process and the claim relates to that property. (The non-resident defendant may send a representative or submit an affidavit to defend against the claim.)
A non-resident defendant who owned or operated a motor vehicle involved in an accident on a California highway — if service of process is made on both the defendant and the Department of Motor Vehicles. Some courts allow the non-resident driver to send a representative (but not an attorney), or submit an affidavit or declaration explaining that person's side of the case, or appear at the hearing by telephone. To determine the court's policy and practice, contact a small claims adviser in the county where the suit has been filed.
