Signing over a car title in Illinois involves a specific process to legally transfer ownership. The core steps are: completing the assignment of title on the back of the current title, getting the correct odometer disclosure, and ensuring both parties sign in the presence of a notary. The seller must provide the signed title to the buyer, who then has 20 days to apply for a new one in their name.
The most critical part is correctly filling out the assignment section on the reverse of the Illinois Certificate of Title. This includes the sale price, date of sale, and the exact printed name, address, and signature of the buyer. The seller must also sign this section. Illinois requires this signature to be notarized. You cannot simply sign the title and hand it over without this notarization, or the buyer will be unable to register the vehicle.
An accurate odometer disclosure statement is mandatory for most vehicles under 16,000 lbs. You must record the exact mileage and check the appropriate box indicating whether the reading is accurate, exceeds mechanical limits, or is not actual mileage. Incorrectly completing this section can lead to legal issues.
The seller should also complete a Bill of Sale (Form VSD 703), which serves as a receipt and records the transaction details. While not always strictly required for the state, it is crucial for both parties' records. As the seller, you should remove the license plates and cancel your insurance only after the sale is finalized. The buyer is responsible for taxes and fees when they title and register the vehicle in their name.
