Payment documentation requirements

How installment sale affects title transfer
In an installment sale, the seller should record a security interest (lien) against the vehicle title at the DMV before the buyer takes possession. This protects the seller if the buyer defaults. The lien is released when the final payment is received. Some states require the security interest to be recorded within a specific number of days of the sale.
Notarization: NOT REQUIRED
Illinois does not require notarization for private vehicle bills of sale. Buyer and seller signatures on the completed title assignment are sufficient.
Important notice
If the buyer defaults and the seller needs to repossess the vehicle, state law governs the repossession process. Self-help repossession may be permitted only if it can be done without breaching the peace. Improper repossession exposes the seller to significant liability.
