Missouri Revised Statutes Title XXXV. Civil Procedure and Limitations § 508.130. Application for disqualification of judge or change of venue--contents

Any party, his agent or attorney, may present to the court, or judge thereof in vacation, a petition setting forth the cause of his application for disqualification of the judge or for a change of venue, and when he obtained his information and knowledge of the existence thereof; and he shall annex thereto an affidavit, made by himself, his agent or attorney, to the truth of the petition, and that affiant has just cause to believe that he cannot have a fair trial on account of the cause alleged. If the removal is asked because of objections to the inhabitants of the county, the application shall not include therein any other county than the one from which the change of venue is asked.
