A Missouri Entry of Appearance is a document that must be filed with the court by an attorney who wishes to represent a party in a case in Missouri. It is a formal document that sets forth the attorney’s name, address, and contact information, as well as the case number and the names of the parties involved in the case. It also serves to inform the court that the attorney is representing the party in the case and that the attorney is authorized to take all required legal actions on behalf of the party. There are two main types of Missouri Entries of Appearance: an “Original Entry” and a “Subsequent Entry.” An Original Entry is filed when an attorney first enters a case and a Subsequent Entry is filed when an attorney is replacing an existing attorney in a case.
