Legal Question in Family Law in California

Yes, you must file the proof of service with the court. You should pick up a copy of How to Do Your Own Divorce In California, by Nolo Press. Before I started doing Family Law, I did my own divorce, and even as a "hot shot" litigator at the time, I found the process confusing and the books in the law library even more confusing. Then I found that book. I still keep a copy around for a quick easy reference.
