A crossclaim is a claim by one party against a coparty arising out of the transaction or occurrence that is the subject matter.

• A. Against a coparty arising out of the same transaction
• B. Against the plaintiff only
• C. Against a nonparty
• D. Against the court

Answer: (A)

A crossclaim is a claim by one party against a coparty in the same lawsuit, and it must arise out of the transaction or occurrence that is the subject matter of the action. The option that describes this situation—against a coparty arising out of the same transaction—fits exactly this concept. It captures the idea that the dispute is between parties on the same side of the case, within the same core transaction, rather than targeting someone outside the case or the court itself.

Why the other ideas don’t fit: a claim against the plaintiff would be a different type of assertion (often a counterclaim in many contexts) and not a crossclaim against a coparty; a claim against a nonparty is outside the scope of a crossclaim, which must be directed at someone already a party; and a claim against the court isn’t a claim against a party at all.
