Private vehicle sales in Colorado are completed through the Colorado Division of Motor Vehicles and a county motor vehicle office. The seller assigns the title, the buyer applies for title and registration, and a bill of sale documents the sale. Colorado DMV's general buying-and-selling guidance calls for buyer and seller signatures and does not state routine notarization.
Record the vehicle year, make, VIN, sale date and time, and both parties' signatures. Use the current state and county instructions to identify any other title or odometer documents required for the transfer.
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.
Keep a signed copy for your records and verify the current title, odometer, registration, and any county-specific document steps before relying on this transaction record.
