N.j. Ct. R. 4:30A
As amended through April 29, 2024
Non-joinder of claims required to be joined by the entire controversy doctrine shall result in the preclusion of the omitted claims to the extent required by the entire controversy doctrine, except as otherwise provided by R. 4:64-5 (foreclosure actions) and R. 4:67-4(a) (leave required for counterclaims or cross-claims in summary actions). Claims of bad faith, which are asserted against an insurer after an underlying uninsured motorist/underinsured motorist claim is resolved in a Superior Court action, are not precluded by the entire controversy doctrine.
