Yes. There are a number of deadlines that you must meet. If those deadlines are not met, the court can involuntarily dismiss your case. For example, you must have something occur within 120 days of filing your petition. You must serve the other party within that time frame. Also, if there is no hearing set, you must file a Motion to Set within that time frame. Otherwise, the court may inform you that the case will be dismissed within 60 days. There are some exceptions to this, however. If there is a motion for summary judgment or motion for judgment on the pleadings, or for genetic testing, the court will usually extend the 120-day time frame.
