Answer: You actually have two options to get the lawsuit. If the matter is a small claims lawsuit, California law allows service by certified mail. The court clerk sends a copy of the claim to the defendant. The defendant must sign and return a receipt to the clerk. There is a fee for this type of service.
In cases where service by certified mail is not allowed (which is most cases) or the box holder will not sign for certified mail federal postal allows you to obtain the address information.

I also recommend bringing along a copy of subpoena, lawsuit or other legal process in case the postal clerks question you. Once you have the address information, you should be able to effect service on the defendant.
