Private vehicle sales in Colorado are completed through the Colorado Division of Motor Vehicles and your county motor vehicle office. The seller assigns the title to the buyer, the buyer applies for a new title and registration, and a bill of sale documents the sale. Notarization is commonly required in Colorado, and some counties require it outright, so it is safest to plan on having the bill of sale notarized and to confirm the rule with your county before the sale.
Colorado publishes a standard Bill of Sale, Form DR 2173, that records the buyer and seller, the vehicle's year, make, model, and VIN, the purchase price, and the odometer reading, which is required for the sale. Because notarization is often expected, both parties may need to sign in front of a notary, so coordinate the signing accordingly.
To complete the transfer, the buyer brings the assigned title, the bill of sale, a Secure and Verifiable Identification, and proof of Colorado insurance to the county motor vehicle office, generally within 60 days of the purchase to avoid late fees. The buyer pays ownership tax, sales or use tax, and title and registration fees at that office.
Confirming the local rule matters in Colorado because requirements can differ between counties. Keep a signed (and where required, notarized) copy of the bill of sale for your records, and verify the current titling and notarization steps with your county motor vehicle office before relying on this document.
