Remedies for improper joinder include severing misjoined claims or parties so each matter proceeds separately, moving to dismiss particular causes of action or defendants for misjoinder or failure to state a claim, seeking remand or opposing removal where joinder was used to defeat jurisdiction (or moving to retain/remove when appropriate), asking the court to strike irrelevant allegations or order amendment of the pleadings, requesting bifurcation or protective orders to limit prejudice and discovery, seeking transfer to the proper venue, and—when warranted—asking for sanctions or interlocutory review; the best lawyers pursue these remedies step-by-step by (1) promptly identifying the defect, (2) attempting a meet-and-confer to narrow or amend pleadings, (3) filing a focused motion (sever/dismiss/remand/strike) supported by statutes and precedent, (4) proposing practical case-management orders (timelines, limited discovery, bifurcation), (5) preserving the record for appeal, and (6) tailoring strategy to local rules and the client’s objectives to minimize delay and prejudice.
