In California, you cannot do this task if you are involved in the case.   A process server should be over 18 years old and have no connection to the case requiring service.   The best way to serve a party is through a Private Investigator or a Registered Process Server, like any one of our employees at Kinsey Investigations. We offer Process Service among our services.  We operate within legal limits, and we have creative ways of making sure the parties are served.
