Misjoinder of parties is not a ground for dismissing an action. On motion or on its own, the Court may at any time, on just terms, add or drop a party. The Court may also sever any claim against a party.
Del. R. Ch. Ct. 21
Comment
In 2023, Rule 21 was revised to align its language with Federal Rule of Civil Procedure 21 so that authorities interpreting the federal rule could be cited more easily as persuasive authority for the interpretation of Rule 21.
No substantive change in the interpretation of the rule was intended, and prior Delaware authorities interpreting the rule remain applicable.
