When a party is harmed by improper joinder the usual remedies are to move to strike or sever the improperly joined claims, seek dismissal of unrelated counts, ask for separate trials or bifurcation, or move for leave to amend the pleadings (or to file a corrected/narrowed complaint); courts may also enter consent orders to reframe the issues, stay portions of the case, or permit joinder correction with costs awarded to the aggrieved party. To resolve it quickly and with minimal delay, act promptly: (1) audit the pleadings to identify the unrelated claims, (2) research the governing joinder rules and supporting case law, (3) confer with opposing counsel to attempt a consent amendment or stipulation, (4) if negotiations fail, file a targeted motion (strike/sever/dismiss or for separate trial) attaching a proposed amended pleading and a short factual chart showing lack of commonality, (5) request interim relief if prejudice or statute-of-limitations risks exist, and (6) preserve the record for appeal while asking the court for tight scheduling to avoid needless adjournments — this mix of swift procedural steps, negotiation, and clear briefing usually fixes the joinder problem without derailing the main litigation.
