18 Del. Admin. Code § 602-3.0
The appraiser shall exchange a legible copy of his appraisal with that of the repair shop selected to make the repairs and also furnish a copy to the owner of the vehicle. This appraisal shall contain the name of the insurance company ordering it, if any, the insurance file number, the number of the appraiser's license and the proper identification number of the vehicle being inspected. All unrelated or old damage should be clearly indicated on the appraisal which shall include an itemized listing of all damages, specifying those parts to be replaced or repaired. Because an appraiser is charged with a high degree of regard for the public safety, the operational safety of the vehicle shall be paramount in considering the specification of new parts. This consideration is vitally important where the parts involved pertain to the drive train, steering gear, suspension units, brake system or tires.
