Buying A Used Car In Colorado From Private Party Apr 2026

Buying a used vehicle from a private party in Colorado involves several legal steps to ensure the transfer of ownership is valid and that you can drive the car legally before registration.

: You must have a VIN-specific insurance policy for the new vehicle immediately.

: You must carry a signed Bill of Sale that includes the year, make, VIN, and the exact time and date of the sale.

When you purchase the car, you must receive and carry specific documents to operate it before you visit the DMV:

: Ensure the seller signs the title exactly as their name appears on the front. If multiple owners are joined by "and," both must sign.

: If you buy the car after-hours (weekends, holidays, or between 5:00 PM and 8:00 AM), you can legally drive it without plates for up to 36 hours —but only directly to your home or a registration office.
