The law covers most classes of motor vehicles including "demonstrators" which have an original retail purchase or lease in Washington and are originally registered in the state (Note: a military exception may apply to the registration requirement). An owner can request an arbitration under Lemon Law at any time within 30 months of the vehicle’s original retail delivery date. You do not have to be the original owner to request arbitration. Later owners of a vehicle may request an arbitration if: the vehicle was purchased within two years of delivery to the original retail consumer and within the first 24,000 miles of operation; the vehicle meets the other eligibility requirements; and the Request For Arbitration is received by the Lemon Law Administration within 30 months of the original retail delivery date.
