Complaint filed by a defendant to initiate their own lawsuit against the a plaintiff, a co-defendant or another party not named in the original lawsuit. The cross-complaint must concern the same events as the original lawsuit.

A cause of action filed by a Defendant against a co-defendant in the same lawsuit. See also Counterclaim.

A document usually submitted by the defendant which lists and describes offenses, ramifications and/or damages alleged against the plaintiff or a third party.

A complaint filed by the defendant (or cross-defendant) against the plaintiff.

An action brought by a party sued--against the party who sued or against a third party.

Sometimes called a cross-claim, legal paperwork that a defendant files to initiate her own lawsuit against the original plaintiff, a co-defendant or someone who is not yet a party to the lawsuit. A cross-complaint must concern the same events that gave rise to the original lawsuit. For example, a defendant accused of causing an injury when she failed to stop at a red light might cross-complain against the mechanic who recently repaired her car, claiming that his negligence resulted in the brakes failing and, hence, that the accident was his fault. In some states where the defendant wishes to make a legal claim against the original plaintiff and no third party is claimed to be involved, a counterclaim, not a cross-complaint, should be used.
