Which of the following is not considered proof of ownership for a motor vehicle in Colorado?

Proof of ownership for a motor vehicle demonstrates that an individual or entity has legal rights to the vehicle. In Colorado, certain documents can effectively serve as proof of ownership, while others do not.

A vehicle subject to a lien typically has a title that explicitly states the lienholder's interest in the vehicle. Although the vehicle owner retains some ownership rights, the presence of the lien means that the lienholder has a legal claim against the vehicle, which complicates clear ownership transfer.

In contrast, a Colorado title assigned to a dealer is a valid proof of ownership as it indicates ownership transfer from the previous owner to the dealer. Similarly, the Colorado Dealer's Out-of-State Vehicle Information Disclosure is relevant for vehicles registered in other states and helps establish ownership when importing such vehicles into Colorado. The Manufacturer's Certificate of Origin (MCO) assigned to a franchised dealer also serves as proof of ownership because it is the original document provided by the manufacturer confirming the establishment of ownership before the vehicle is sold to a consumer.

Thus, due to the existence of the lien that restricts clear ownership, a vehicle subject to a lien on the title does not serve as proof of ownership in the same way that the other documents do.
