Illinois Bill of Sale
Whether you are buying or selling a car, truck, motorcycle, boat, or piece of equipment in Illinois, a properly completed bill of sale protects both parties and satisfies IL record-keeping requirements. Illinois does not require notarization for a standard bill of sale, which simplifies the process for both buyers and sellers. Use the information below to understand exactly what Illinois expects before you complete your transfer.
Illinois Bill of Sale Requirements
To create a legally valid bill of sale in Illinois, you must include the following information. Missing any of these details could delay your title transfer or leave you unprotected in a dispute.
- Full legal names and addresses of buyer and seller
- Vehicle description including year, make, model, VIN, and color

- Odometer disclosure for applicable vehicles
How to Transfer a Vehicle Title in Illinois
The buyer must submit the assigned title, bill of sale, completed RUT-50 tax form, proof of insurance, and applicable fees at a Secretary of State facility within 20 days of purchase.
Pro Tip
Complete the bill of sale at the same time the title is signed over. Having both documents ready together prevents trips back and forth to the IL Secretary of State's office.
Notarization Requirements
Illinois does not require notarization for a standard bill of sale. The document is considered valid once both the buyer and seller have signed it. This means you can complete the transaction without scheduling a separate notary appointment, saving both time and money.
That said, you may still choose to have the bill of sale notarized voluntarily. A notarized document carries additional weight in the event of a legal dispute, and some buyers or sellers prefer the added assurance for high-value transactions.

Always keep a copy of the signed bill of sale for your personal records. Both the buyer and the seller should retain their own copy. In the event of a future dispute about the sale, your bill of sale serves as primary evidence of the transaction terms.
