When multiple causes of action are improperly combined, advocates should act quickly and methodically: first review the pleadings to identify which claims are unrelated by facts, parties, or legal basis; then consider filing a motion to strike, sever, or dismiss the improperly joined claims (or a motion for separate trials) while preserving jurisdictional arguments and any statute-of-limitations concerns. Next, seek leave to amend pleadings if amendment can cure the defect, and support your procedural motions with clear citations to governing rules and case law; if practical, negotiate a consent order with opposing counsel to avoid delay. Throughout, keep the client informed about risks (dismissal, delay, added costs) and document every step so the record is clear on appeal, and afterward adopt best practices—draft narrowly, plead causes tied to common facts when appropriate, run early conflicts/joinder checks, and raise objections promptly—to minimize recurrence.
