A party asserting a claim, counterclaim, crossclaim, or third-party claim may join, as independent or alternative claims, as many claims as it has against an opposing party.
Del. R. Ch. Ct. 18
Comment
In 2023, Rule 18 was revised to align its language to the extent possible with Federal Rule of Civil Procedure 18(a) so that authorities interpreting the federal rule could be cited more easily as persuasive authority for the interpretation of Rule 18.
No substantive change in the interpretation of the rule was intended, and prior Delaware authorities interpreting the rule remain applicable.
