Colorado Bill of Sale Forms (5)


A Colorado bill of sale form grants a taxpayer permission to claim an item as their own after purchasing it from another person. Once the trade occurs, the seller cannot claim possession or request the item back. Similarly, the buyer cannot demand a refund or use the seller’s name unlawfully. The form binds each person to the promises within, meaning the buyer must pay the seller the total amount, and the seller must give the property to the buyer without question.


  • Vessel and vehicle owners must use the state form but do not need to notarize it.
  • Private gun sales require a background and mental health history check.
  • Residents must register boats, cars, and trailers to use them in the state.

What is a Colorado Bill of Sale?

A Colorado bill of sale enforces ownership upon a willing party following their payment to the original owner and signature in the form. The seller is also responsible for signing, which shows that they agreed to the deal and received funds or another item in return.

After buying the personal property, the individual can do whatever they want with it, as long as state law allows it. For example, they can take the possession out of state, store it in a garage, replace parts, or perform actions that an owner would typically carry out.

If the sale involves animals, such as cats, dogs, or horses, the owner must ensure they properly care for them to give them a good quality of life. In some cases, the seller might check up on the new owner (with permission) to ensure they treat the pet(s) well.

Registration Forms: Boats

The registrar must bring the applicable forms to a Colorado Parks & Wildlife (CPW) office.

  • Bill of Sale – Used when a new owner acquires a boat by paying or trading with a seller. If not available, the individual can submit another verifying document.

  • Registration & Title – Must include the previous or current owner’s name.

Colorado residents (or non-residents) do not need to register their guns or have a permit to buy.
