If he will accept service by mail, you can mail the documents to him with a Notice and Acknowledgment of Receipt (form FL-117) which he would sign and return. If he agrees to do so, then you don't need to have him professionally served. Another option is to have someone you know in the UK serve him with the documents. They don't have to be served by a professional. Once you get him served, you can seek orders for support and attorney's fees to assist with the rest of your case.
