Preparing for an arbitration hearing
Make the timeline easy to follow and the requested remedy precise.
What to do, in order
- Read the current rules, manufacturer summary and notice of hearing. Confirm submission deadlines, permissible remedies, evidence sharing and hearing format.
- Create a one-page chronology and numbered evidence index. Tie each concern to repair attempts, persistence and effect on use, safety or value.
- Prepare a concise explanation based on personal observations. Disclose contrary facts and clarify disputed records rather than ignoring them.
- Ask about document corrections, witnesses, vehicle inspection and accommodations in advance. Follow the program instructions rather than this guide’s general suggestions.
- Read the written decision and acceptance terms carefully. Seek advice about its effect before accepting a settlement or award.
