Trailer Bill of Sale Basics

Think of a trailer bill of sale as the receipt for a trailer sale. It records who sold the trailer, who bought it, what the vehicle is, how much the buyer paid and when. That gives both sides a written record of the change of ownership. Each person can keep a signed copy.

The bill of sale is a separate paper from the certificate of title, and the title steps come later on this page. You can use the free FormsPal template to create one, or download the PDF and complete it by hand.

Colorado Bill of Sale Requirements for a Trailer

Colorado does not always require a bill of sale for a trailer. The DMV says a bill of sale is not needed for the title transfer if all the information on the title is completed correctly. A bill of sale is best practice, and it is required if the sale price is not listed on the title.[2]

A trailer bill of sale in Colorado should cover these points:

  • Seller: use the seller's full name. First initial and last name is not acceptable for the seller or the seller's agent.[1]
  • Trailer: give the vehicle description, which means the year, make and VIN.[1]
  • Price and date: enter the purchase price and the date.[2]
  • Signature: the bill of sale must be signed. The DMV form deals with the case where the original title was not signed by the owner listed on the title.[1]
  • Lien: if a lienholder has a lien on the trailer, the lien must be released. The DMV form asks for the date the lien was released.[1]

This document is also called a Colorado utility trailer bill of sale. Many sellers keep a signed copy of it, and a photo of the signed title, for their own records.

Title Transfer and the 60-Day Deadline

After the sale, Colorado DMV says buyers have 60 days from the date of purchase to title and register the vehicle. To transfer the title, the seller provides the properly endorsed Colorado certificate of title.[2]

Mark the purchase date on the bill of sale and on your calendar. Our deadline calculator counts the 60 days for you.

The Owner's Declaration Under Colorado Law

When a titled vehicle is sold in Colorado, the person in whose name the title is registered, if not a dealer, must make a formal transfer of the vehicle. That person, or the person's agent or attorney, affirms the sale or transfer with a written declaration made under the penalties of perjury in the second degree.[3]

The statute says:

Upon the sale or transfer of a motor or off-highway vehicle for which a certificate of title has been issued or filed, the person in whose name the certificate of title is registered, if the person is not a dealer, shall execute a formal transfer of the vehicle described in the certificate. The person in whose name the certificate of title is registered or the person's agent or attorney shall affirm the sale or transfer, accompanied by a written declaration that the statement is made under the penalties of perjury in the second degree, as defined in section 18-8-503, c.r.s.

Frequently Asked Questions

Does a trailer bill of sale need to be notarized in Colorado?

Colorado has no statute that requires a bill of sale to be notarized. The state's published requirements for the document do not list notarization either. Instead, the owner of a titled vehicle affirms the transfer with a written declaration made under the penalties of perjury in the second degree.[3]

If you want a notary to acknowledge the signatures anyway, FormsPal also has a Colorado notary acknowledgment form.
