Interrogatories are a list of questions submitted by an attorney after a complaint is filed. if someone sues you for assault and battery, your attorney will send a list of questions to the plaintiff for him to answer. The questions are designed to give your attorney knowledge of the specifics of the plaintiff's claim, so he can begin to form a defense.

The questions are geared to the specific circumstances and elements needed to make out a claim for assault and battery (which are actually two separate claims).
