When a plaintiff splits a cause of action across multiple suits, it generally violates the procedural principle that all claims arising from the same transaction or occurrence must be brought together in one action; courts view this as a misuse of judicial process that can lead to dismissal of subsequent suits, application of res judicata, or even cost penalties for abuse of process. Best lawyers handle such procedural missteps by first identifying whether the claims truly stem from the same cause of action, then seeking to consolidate related cases, amend pleadings to join all claims, or withdraw duplicative suits before a court rules on them; they also use precedents and procedural rules to argue that no actual splitting occurred if separate legal rights or distinct transactions are involved, thereby safeguarding their client’s substantive rights while maintaining procedural integrity.
