Step-by-Step: Filling Out Your Naperville Car Bill of Sale
- 1
Enter seller and buyer information
Write full legal names and current addresses exactly as they appear on government-issued IDs. Both buyer and seller must use their full legal names — no nicknames or abbreviations. Errors here cause delays at the IL Secretary of State – Naperville Facility.
- 2
Record Car details and VIN
Enter the year, make, model, body style, color, and the 17-character VIN exactly as printed on the dashboard (visible through the windshield) or door jamb sticker. The VIN must match the vehicle title exactly. Also enter the current odometer reading — federal law mandates accurate odometer disclosure for vehicles under 10 model years old.
- 3
Record sale price, date, and payment method
Write the agreed sale price in both numeral form ($12,500.00) and written form (twelve thousand five hundred dollars). Enter the exact date of the sale — this date triggers the Illinois title transfer requirement. Note payment method: cash, check, or other.
- 4
Both parties sign and date
Both buyer and seller sign and date the completed form. Sign with blue or black ballpoint ink. Illinois does not require notarization for private vehicle sales. Print at least two originals — one for each party.
