You aren't required to file jointly ever, but for tax year 2012, filing jointly may be preferrable to filing married filing separately. It is your joint choice on what to do. As for service, if he signs and returns a Notice and Acknowledgment of Receipt (FL-117) and you file that attached to a proof of service, then he will be properly served. He doesn't have to be formally "served" if he accepts service by mail. Just have someone other than you sign the bottom of the Notice and Acknowledgment of Receipt and the Proof of Service forms.
