Divorce papers must be served to the other party through a legally recognized process. If your ex-spouse actively avoids the service of these papers by refusing to sign them, not answering the door to receive the papers, or moving to an unknown location, it can make the process difficult. If you are not able to find a person over 18 who can access your ex to serve them the papers, you can also serve them through publication or posting. This means you could publish the divorce summons in a newspaper or at a courthouse. If the other spouse does not respond after a sufficient amount of time, you are free to continue with the divorce process on your own.
