Bill of Sale Requirements in Colorado

What is a Bill of Sale for a Car in Colorado?

A bill of sale is a record proving a change in vehicle ownership at the time of the sale or gifting. Colorado requires a bill of sale only in specific circumstances, though generally requires only a title transfer to assign ownership from a seller to a buyer. Even if your transaction doesn't require a bill of sale, it's still a good idea to have one as a receipt of your purchase or sale, a helpful record for tax time, or as protection against legal issues in the event the buyer does not register or abandons the vehicle.

When do you need a Bill of Sale in Colorado?

Colorado requires a bill of sale when:

  • The buyer has to drive the vehicle before registration because it was purchased after-hours.
  • There is no space on the title to record an odometer reading.
    • In this event, the seller must purchase a Motor Vehicle Bill of Sale (Form DR 2173) through a state-approved vendor.

  • A vehicle description and vehicle identification number (VIN).
  • The vehicle's final sale price.
  • Names of the buyer and seller.
  • The date and time of the sale.

We also provide a generic bill of sale that's printable and easy-to-use. Mark the date AND time of purchase on whichever bill of sale you use.
