Rule 3024. Motion to correct pleadings. (a) Vague or ambiguous pleadings. If a pleading is so vague or ambiguous that a party cannot reasonably be required to frame a response he may move for a more definite statement. (b) Scandalous or prejudicial matter. A party may move to strike any scandalous or prejudicial matter unnecessarily inserted in a pleading. (c) Time limits; pleading after disposition. A notice of motion under this rule shall be served within twenty days after service of the challenged pleading. If the motion is denied, the responsive pleading shall be served within ten days after service of notice of entry of the order and, if it is granted, an amended pleading complying with the order shall be served within that time.
