Appearance

If an appearance has been entered through FRAUD or mistake or after the plaintiff's complaint has been materially amended, the discretion of the court may permit the appearance to be withdrawn. A proper withdrawal is treated as if no appearance at all had been entered in the case. A defendant who has withdrawn a general appearance may ask the court for leave to file a special appearance to challenge the court's jurisdiction.

If someone makes an unauthorized appearance on behalf of the defendant, it may be stricken or set aside by a motion of any party with an interest in the proceeding.
