so Colorado law says to replace a lot title I have to have:
If your title has been lost, stolen or damaged, you can get a duplicate title by going to your nearest county office. Make sure to bring the following materials:
If your vehicle was purchased on or after July 1, 2006 you must provide appropriate identification.
VIN number and title number.
Payment of $8.20 for the duplicate title.
I found an old registration under the original owner's name that has the VIN and the Title No. Is that enough?
