A Defendant may bring a cross-claim against a Plaintiff or third parties in an action before the court. A cross-claim should be pleaded in the existing action if it arises out of the same facts or transactions as the Plaintiff's claims. A Defendant's cross-claim against a third party need not be related to the subject matter of the Plaintiff's claim. A third party to the proceedings can also bring a further cross-claim against the original Defendant and/or the original Plaintiff. (See also Counter-claim)
