Legal Question in Family Law in California

If you know for sure the person's home or business address, and the process server makes at least three attempts at that address and can't find the defendant there, the process server may then leave the papers with someone else at that address who is at least 18 years old and "apparently in charge" of receiving deliveries at the place of business or "apparently a resident" at the home address. The process server must then also mail copies of all the papers to the same address. Then instead of immediately starting the time for the defendant to respond, it is delayed ten days from the date of mailing. Service is considered completed at that time. Note there are also special requirements for the proof of service if it is done that way.
