What is a Change of Judge?

In the State of Missouri, under Supreme Court Rule 51.05, a party is allowed one automatic change of the judge that has been assigned to their case.  The party must file a motion requesting the change of judge within 60 days of service of process or 30 days of the assignment of a new judge, whichever is longer.  In divorce cases, this would mean filing the motion within 60 days after your spouse has been served with dissolution papers.
