Utah trailer — quick answer
Utah draws its line at 750 pounds unladen. A non-commercial trailer at or under that weight is exempt from titling altogether, which makes the bill of sale the ownership record; anything heavier, travel and tent trailers included, must be titled and registered.
How trailer sales actually work in Utah
- Title threshold
- Every trailer over 750 lbs, travel and tent trailers included, must be titled and registered
- Exemption
- Non-commercial trailers with an unladen weight of 750 lbs or less are exempt from titling
- Application
- Form TC-656, Vehicle Application for Utah Title and Registration
- VIN inspection
- Form TC-661, Certificate of Inspection, when titling in Utah for the first time
- Purchase price
- Listed on the title being transferred, or on a bill of sale
- Registration
- A fee at initial registration and annually thereafter
- Identification
- Every owner listed on the application must provide government-issued ID
Transferring a trailer in Utah, step by step
- Find the unladen weight before anything else. At 750 lbs or less and non-commercial, Utah issues no title and your bill of sale is the ownership record.
- Above 750 lbs, the seller signs the title over and the buyer applies on Form TC-656.
- Put the purchase price somewhere it can be read — on the title being transferred, or on the bill of sale.
- Expect a VIN inspection on Form TC-661 if the trailer is being titled in Utah for the first time, which includes most out-of-state purchases.
What private buyers get wrong here
- A small utility trailer sold with no title is normal in Utah rather than suspicious, but it means losing the bill of sale means losing your proof of ownership.
- The exemption is for non-commercial trailers. Commercial use puts the trailer back into the titling requirement regardless of how light it is.
- Every owner named on the application needs government-issued ID, so a purchase in two names needs both people available.

Does a Utah trailer bill of sale need to be notarized?
Check the instructions for the specific title and bill-of-sale form. A requirement to notarize a title assignment does not automatically mean the separate bill of sale needs notarization. If notarization is required, wait to sign until the notary instructs you.

Utah Trailer Bill of Sale — FAQ
Is a trailer bill of sale required in Utah?
Utah draws its line at 750 pounds unladen. A non-commercial trailer at or under that weight is exempt from titling altogether, which makes the bill of sale the ownership record; anything heavier, travel and tent trailers included, must be titled and registered.
Does a Utah trailer bill of sale need to be notarized?
Check the signing requirements for the specific title and bill-of-sale form. Notarization of a title assignment and notarization of a bill of sale are separate questions; a car rule does not establish the rule for this item.
Do I need to title a trailer?
It depends on the trailer’s weight and your state. Heavier trailers usually require a title and registration; many small utility trailers only need registration. Check your state page.
What if my trailer has no VIN?
Homemade or older trailers may need a state inspection to be assigned a VIN before they can be titled. The bill of sale still documents the sale in the meantime.
Is a bill of sale proof of ownership?
Generally no. For titled property like a car or boat, the title is what proves ownership. A bill of sale proves that a sale happened and records the price, date, and terms — it supports the title transfer but does not replace it. For untitled property (furniture, equipment, electronics), the signed bill of sale is usually the main proof of ownership.
