Counterclaim - sustany/dvg GitHub Wiki

A counterclaim is defined as a claim for relief filed against an opposing party after the original claim is filed. Most commonly, a claim by the�defendant�against the�plaintiff.

Overview:

When composing an�answer,�defendants�may assert their own claims against the�plaintiff. For all purposes within the trial, the�plaintiff�acts in a defensive posture regarding these counterclaims, and the�defendant�acts in an offensive posture. Thus, for example, the�defendant�bears the burden of proof on counterclaims.

There are permissive and compulsory counterclaims. "Common law compulsory counterclaims" are counterclaims that, if successful, would nullify the�plaintiff�s�claim. If defendants do not raise these counterclaims, they cannot sue on them later in a different lawsuit. For example, if Company A sues Company B for breach of contract, and Company B did not make any counterclaims, Company B could not later sue Company A for fraudulently inducing it to sign the contract in the first place.�See�Res Judicata.�See, e.g.,�Cardinal Chemical v. Morton International.

Many jurisdictions have also created additional classes of compulsory counterclaims. For example,�Rule 13�of the�Federal Rules of Civil Procedure�requires defendants to raise as a counterclaim any claim they have against parties already in the lawsuit if the claim "arises out of the same transaction or occurrence" as one of the plaintiff's claims.

Permissive counterclaims are counterclaims addressing matters unrelated to the�plaintiff�s�claims. This allows parties to settle all their otherwise unrelated disputes in one single lawsuit.

If the�defendants��counterclaims address the same basic issues as the�plaintiff�s�claims, courts usually address the claims and counterclaims at the same time. If the counterclaims involve distinctly different issues or facts, the court may choose to address them separately.
