Which is true about a supplemental bill of particulars in a personal injury action?

In the context of a personal injury action, a supplemental bill of particulars is designed to refine or add to the details that have already been provided in the original bill of particulars. This supplementary document typically addresses matters such as continuing special damages, which refer to damages that accrue after the initial filing and require clarification or expansion of the existing details.

Special damages can include specific financial losses like medical expenses or lost wages that have continued to accumulate or have newly arisen since the case was initially filed. Thus, a supplemental bill of particulars serves the purpose of updating the court and the opposing party about these ongoing financial impacts relevant to the case.

The other options do not accurately represent the nature or requirements of supplemental bills of particulars. For instance, new causes of action cannot be alleged in a supplemental bill; it is meant to clarify or expand on existing claims rather than introduce entirely new ones. Additionally, a supplemental bill of particulars is typically filed after the original bill, and while it does not necessitate a formal response—more so serving as a notification to the opposing party regarding updated information—it still operates within the framework of the ongoing litigation.
