The best approach is to promptly schedule a transparent meeting where you clearly explain that the dismissal was based solely on procedural grounds—not the case's merits—using simple analogies (e.g., "filing in the wrong neighborhood") to demystify territorial jurisdiction, while immediately presenting a structured action plan that outlines the transfer or refiling process in the proper court, reaffirms your commitment to their case, and provides a realistic revised timeline and cost estimate to rebuild confidence and maintain trust despite the setback.
