The success of a Lemon Law claim rarely hinges on the severity of the defect alone; rather, it relies heavily on the quality of the documentary evidence. When a claim enters litigation or arbitration, the burden of proof rests on the consumer to demonstrate the vehicle’s repair history and ownership status.

Maintaining a comprehensive file of the following documents is critical for a favorable resolution.

1. The Repair Orders (Service Invoices) The cumulative repair history is the cornerstone of any Lemon Law case. Consumers should retain the final invoice for every dealership visit, including those for routine maintenance or inspections where no repairs were performed. These documents establish the timeline of the defect and the number of repair attempts afforded to the manufacturer.
2. The Purchase or Lease Agreement This contract establishes the financial baseline for any potential damages. It details the vehicle identification number (VIN), the date of purchase, the purchase price, and the breakdown of collateral charges such as sales tax, registration fees, and dealer preparation fees. This data is essential for calculating the statutory repurchase amount.

3. A Contemporaneous Timeline A personal log of vehicle issues can provide context to the official repair records. This should include dates of service, the specific nature of the defects, the duration the vehicle was out of service, and the names of service personnel involved. This timeline assists counsel in reconstructing the history of the vehicle’s nonconformities with precision.
