Basically, you cannot locate your spouse. You want a divorce. You can file a request for the court to allow you to do a "publication" divorce. It slows down the divorce process. You must do it exactly correctly or it won't work.
Now with the internet, most courts require that you make a detailed search. Many courts will appoint an attorney to find the spouse. YOU get to pay for their time and costs -- start at $500 to $2,000.
It saves you much and time to locate your spouse!
