An Illinois motor vehicle bill of sale documents the purchase and sale of a motor vehicle between a private seller and buyer in the State of Illinois. It serves as proof of a legal change of ownership and reflects details of the sale like the vehicle's age and condition at the time of purchase.

Required Forms

Odometer Disclosure Statement for Title Transfers (Form VSD 333.4) – Required upon transferring the title of a motor vehicle to verify the odometer mileage has not been altered.

Seller’s Report of Sale (Form VSD-703) – The seller must submit this form to the Secretary of State’s Vehicle Services Divison immediately after selling the vehicle.

Registering a Vehicle

Whether acquiring a vehicle through purchase, gift, or inheritance, it must be registered with the state within twenty (20) days of the transaction. All individuals purchasing a vehicle privately– that is, not through a dealership– are responsible for completing all paperwork toward registering the vehicle under the new owner. Once registered, plates must be renewed annually; renewing a registration can be done online via the Vehicle Services page.

Where to Register

Vehicles can be registered in-person at the nearest Secretary of State (SOS) office, or all documentation can be sent by mail.
