A plaintiff seeks to add a party after filing the complaint. The new party was not named in the original complaint but was served within the period for serving the summons and complaint. The claims against the new party arise from the same conduct as the original complaint. Under Rule 15, this amendment is allowed if:

• A. The new party was not served within the time period
• B. The party to be brought in received timely notice and would not be prejudiced
• C. The new party did not know about the action
• D. The addition would destroy diversity jurisdiction

Answer: (B)

Rule 15 allows adding a party after the complaint, and when you want to relate that amendment back to the original filing, the new party must have been served within the time allowed for service and must have received timely notice such that no prejudice results. The claims must arise from the same conduct, transaction, or occurrence as the original pleading. In this scenario, the new party was served within the service window and the claims come from the same conduct as described in the original complaint, so the amendment can relate back under Rule 15. The key is that the party had timely notice and that allowing the amendment would not prejudice its ability to defend on the merits. If either of those conditions weren’t met—if service wasn’t timely or if the party would be prejudiced—the amendment could not be permitted. The issue of diversity jurisdiction is separate and not the controlling factor given these facts.
