A caption must accompany your move. A motion's caption is similar to that of a complaint, except that with a move, you do not need to mention all of the plaintiffs and defendants. In the case of many plaintiffs and/or defendants, you may specify merely the first plaintiff and first defendant, followed by "et al." (for other plaintiffs and defendants). The purpose of the caption is twofold: first, it provides information about what kind of motion it is; second, it gives notice to other parties involved in the litigation. For example, if you are the plaintiff in a lawsuit and you file a motion for summary judgment without a caption, then everyone should know that you are seeking summary judgment against only yourself. If you include additional parties in the caption, then they will also be given notice that you are filing a motion for summary judgment. Similarly, if you are the defendant in a lawsuit and you file a motion for summary judgment without a caption, then everyone should know that you are seeking summary judgment against only yourself. In general, any word or phrase that identifies the nature of the motion is called a "caption-worthy term". For example, "motion to dismiss" is a caption-worthy term because it tells others what kind of motion it is.
