Hawaii Counterclaim is a legal process used to challenge the claims of a plaintiff. This process is used in civil litigation in the state of Hawaii. The defendant can file a Hawaii Counterclaim to assert their rights and interests in response to the plaintiff's claims. There are two types of Hawaii Counterclaim: Compulsory Counterclaim and Permissive Counterclaim. Compulsory Counterclaims are claims that must be brought in the same legal action as the plaintiff's claims and are based on the same facts. Permissive Counterclaims are claims that the defendant can bring in the same legal action as the plaintiff's claims, but they are based on different facts and are not legally required.
