You need to serve him with the papers that are filed and, if you dont know where he is, you will need to obtain a court order to serve by publication. Since this will take some time to achieve anyways, you should amend the Petition and whatever other documents you filed with the court so that when the papers are published, he will be effectively served with the papers containing current information.
