A Practice Note discussing initial considerations for counsel to an action where a party notices the physical or mental examination of another party under New Jersey Court Rule 4:19 (commonly called a defense medical examination (DME) or an independent medical examination (IME)). This Note explains when grounds for a DME exist, who may conduct a DME, and the DME's purpose. It also addresses the examination report and navigating the DME's logistics, including the defendant retaining a third-party vendor, the parties selecting an examination date, and the plaintiff's intent to record the DME or have a neutral third party observe it.
