Seller guidance

Auction sellers must disclose known material defects and any title issues before bidding opens. If the vehicle has a salvage, rebuilt, or branded title, this must be disclosed prominently in the auction listing. Reserve the right to require a deposit or full payment before releasing the vehicle. Provide the buyer a signed bill of sale and a copy of the title (or title assignment) once payment clears.

Buyer guidance

Auction vehicles are sold as-is — inspect thoroughly before bidding if possible. Verify the title is present and free of liens before the auction closes. If the title will be delivered after the sale, ensure the bill of sale documents the VIN, purchase price, and the seller's agreement to transfer clear title. Do not pay registration or sales tax until you have confirmed title delivery.

Legal considerations

Auction sales are governed by UCC Article 2 (§ 2-328 — sale by auction) and applicable state motor vehicle transfer laws. Under UCC § 2-328(3), each lot is a separate sale. An "as-is" disclaimer under UCC § 2-316 is effective in auction sales. Many states require the auction house to be a licensed dealer (e.g., California Business and Professions Code § 11700). Title branding laws require disclosure of salvage, flood, or lemon law buyback status.
