I see by another thread of yours that there were multiple means of service used. Has the dog sled and carrier pigeon shown up yet?
If service was considered valid and you did not dispute jurisdiction, that would mean you acquiesced to California jurisdiction.
If you have not been "legally served", then until you are you don't do anything. Once served, if he has not met the requirements to file in California, you respond with a claim that California does not have jurisdiction due to a lack of residency of either party.
Oh, are you a California resident? If so, then his residency doesn't matter.
