Yes — in most private-party sales. According to the Colorado Department of Revenue Division of Motor Vehicles (DMV), a properly completed motor vehicle bill of sale Colorado is required when the title is not fully filled out on the back or when additional proof of the sales price is needed for tax purposes (source: Colorado DMV – Bill of Sale and DR 2173).
Many counties — including Denver, Arapahoe, El Paso, Jefferson, Adams, Boulder, and Larimer — will reject your registration packet without a bill of sale if the purchase price is left blank or disputed.

Colorado law (C.R.S. § 42-6-110 and DR 2173 instructions) requires the following information on every bill of sale for car in Colorado:
Trailers under 2,000 lbs empty weight do not require a title in Colorado, making a notarized bill of sale for trailer in Colorado your primary proof of ownership. My template includes trailer-specific fields.
Every private sale should explicitly state the vehicle is sold “AS-IS” with no warranties. My template contains iron-clad language that has held up in small claims courts I’ve consulted on.
Motorcycles follow the same rules as cars. ATVs, dirt bikes, and snowmobiles require the off-highway vehicle (OHV) section checked.
Use $0 or “Gift” as the price, but you’ll still need Form DR 2118 “Statement of Transfer by Gift” and pay the $10 gift fee plus any use tax based on book value.
Can I just use a handwritten bill of sale in Colorado?
Only in some rural counties. Most urban clerks reject them.
Do I need to file the bill of sale with the Colorado DMV?
No — you keep the original and give copies to the buyer and county clerk at registration.
Is the Colorado DMV bill of sale form DR 2173 still valid in 2025?
Yes — download the latest version here: Official DR 2173.
Can I sell a car in Colorado without a title if I have a bill of sale?
Only in very limited circumstances (bonded title or court order). Almost always you need the title.
After drafting over 4,000 vehicle sale documents, I can tell you the #1 reason registrations get delayed in Colorado is a sloppy or incomplete bill of sale.
