A Colorado bill of sale is a form used to record the official sale of items sold in Colorado. The buyer and seller should keep a copy of any bill of sale for their records.
Bill of Sale – By Type (5)
Use a boat bill of sale to transfer ownership of recreational water vehicles (such as motorboats, sailboats, yachts, and jet skis).
Use a trailer bill of sale to buy or sell a trailer (or any non-motorized vehicle pulled by another vehicle).
In Colorado, a bill of sale is only required in certain circumstances. A title transfer should generally suffice when a seller reassigns ownership of a vehicle or vessel to a buyer. A bill of sale becomes necessary when a vehicle is purchased after hours and must be driven prior to registration. It is also necessary when there is no space on the current title for the odometer reading.
The state provides an official bill of sale but is usually only available for purchase through a state-approved vendor. The exceptions are the few counties that provide their bills of sale. You will have to call your county’s local Division of Motor Vehicles (DMV) to find out if your county is one of them  . For example, Broomfield County provides a form on its website.
Bill of sale in Colorado and other DMV documents is not translated into Spanish or any other language. Also, the state does not provide interpreters; however, you may bring your own. All translated documents must state the following, typed or printed on the same page:
“I, (insert translator name), affirm that the foregoing is a complete and accurate translation from (insert name foreign language) to the English language to the best of my ability. I further affirm that I am fully competent to translate from (insert name of foreign language) into the English language and that I am proficient in both languages.”
The bill of sale must be signed by both the buyer(s) and the seller(s).
Number of Copies
If a bill of sale is needed to complete a vehicle or vessel sales transaction, then you will need one copy to submit to the state, along with a copy for the buyer and a copy for the seller. If a bill of sale is not legally needed, you should only have to make copies for each party to the sale.
