Do I need to keep a copy of the receipt?
Yes. Place it in your vehicle. The receipt is proof of registration until you receive your Certificate of Vehicle Registration.
What happens if I don't submit the paperwork?
Wisconsin statute s.342.15 (Transfer of interest in a vehicle) for information regarding requirements for transfer of the vehicle and any penalties that may apply for failure to comply with Wisconsin law.
Summary of statute: When an owner sells a vehicle, the owner should sign their title over to the new owner. Upon receipt of title, the new owner should promptly complete and submit an application to transfer the vehicle into their name. An owner who has delivered possession of the vehicle to the new owner and has complied with the provisions of this statute is not liable as owner for any damages thereafter resulting from operation of the vehicle.
