Legal Question in Family Law in California

Can you explain what you men by hand written note? To be considered proper service the serving party must serve court documents, not had written notes. Court documents will be signed by the Judge or the Clerk and will include the type of matter and the date, time and department where the served party is to appear.

Many Courts have online programs where you can look up and see if there is a proceeding that is scheduled.

If the party has been served official documents he must appear. In this case your step-son would have to appear at both courts and let the Courts decide where venue would be proper.

I disagree that it really matters what she served. I just handled a case of dueling service for a client and the absolute rule is that when there are competing family law cases filed in different counties, the one served first is the one that goes forward and the other must be dismissed. Your step son will, however, probably have to hire an attorney to get whatever she filed in San Bernardino County dismissed.
