When you think of "written discovery," what comes to mind? Likely you think first of requests for documents under R. 4:18 and interrogatories under R. 4:17. Many litigators probably even have forms for discovery under those two rules. However, requests to admit under R. 4:22, a third category of written discovery, are much less likely to come to mind and much less likely to exist as a form in a litigator's toolbox. This underutilized and underappreciated type of written discovery can be a powerful tool to narrow issues in litigation in a way other forms of discovery cannot; it should be considered for more frequent use.
