Rule 444. If the respondent believes that a complaint is so vague or ambiguous that the respondent cannot reasonably be required to respond to it, the respondent may file and serve, upon the complainant, a motion requesting that the allegations or other matters contained in the complaint be made more definite and certain. The motion shall specify the defect complained of and the details requested. The respondent shall answer those portions of the complaint that are not subject to the motion. If the motion is granted, the complainant shall have an opportunity to file an amended complaint within the time specified in the order granting the motion.
