A cross-claim is a claim filed by one party against a co-party arising out of the transaction or occurrence that is the subject matter of the original action. It may include a claim that the co-party is liable to the cross-claimant for all or part of the claim asserted against the cross-claimant. What is a key requirement for a cross-claim?

• A. It must arise out of the same transaction or occurrence
• B. It must be independent of the original action
• C. It must involve a different subject matter entirely
• D. It must be based on a contract with a third party

Answer: (A)

A cross-claim is allowed because it must be tied to the same event that gave rise to the original lawsuit. The key idea is that the dispute between co-parties arises from the same transaction or occurrence, so one court can resolve all related issues in one proceeding. This connection promotes efficiency, avoids duplicative suits, and helps ensure consistent judgments about the involved facts. If the claim weren’t linked to the same transaction, you’d be inviting unrelated issues into the case, which would fragment litigation rather than streamline it. So, the essential requirement is that the cross-claim arise out of the same transaction or occurrence as the original action.
