You have to file a complaint (lawsuit) asking for a divorce. You cannot file a divorce complaint until after you and you spouse have been separated for one year. You have to serve your spouse with the complaint. Service is usually accomplished by certified mail or Sheriff. Then you will need a hearing in front of a judge. You may or may not have to be present at this hearing depending on what county you file in, and whether you are represented by an attorney. The judge has to enter a Judgment declaring you are divorced. You are not divorced until the judge signs a Judgment and the clerk file stamps it.
