What must take place in the event that a pleading asserting a new claim becomes necessary against a defaulted party?

When a pleading asserting a new claim against a defaulted party becomes necessary, the correct action is to serve the new claim on that party. This procedure is essential because it ensures that the defaulted party is formally notified of the new allegations being made against them. Even if a party has defaulted and is not actively participating in the case, they still have the right to be informed of any additional claims or changes to the existing claims.

Serving the new claim allows the defaulted party the opportunity to respond to the new allegations if they choose to do so. This is important for maintaining fair legal processes and ensuring that all parties are given notice of legal actions that may affect their rights.
