A trailer bill of sale records who sold the trailer, who bought it, how to identify it and what was agreed. It matters because trailers often change hands with little paperwork, and the details are easy to dispute later.
What it is
A trailer bill of sale is a short document that both people sign. It names the seller and the buyer, describes the trailer with its VIN or serial number, size and weight rating, states the price and how it was paid, and says whether it was sold as is. Like any bill of sale, it supports the title or registration paperwork instead of replacing it. Whether a trailer is titled or only registered depends on your state, and often on the trailer's weight.
What to include
- The full names and addresses of the seller and buyer.
- The type, year, make, model and color of the trailer.
- The VIN or serial number, or the state-issued number for a homemade trailer.
- The length, number of axles and weight rating (GVWR).
- The hitch type and the brake type.
- The price, the date and how it was paid.
- Whether it is sold as is or with a warranty, and a statement about liens.
- Any extras included, such as a spare tire or ramps.
- Signatures from both people, with the date.
How to fill it in
- Find the VIN or serial number on the title, the registration and the trailer's frame tag. They should all match.
- Pick the trailer type and enter its length, axles and weight rating. The weight rating is usually on a sticker or plate near the front.
- Choose the hitch and brake type.
- Enter the price, the date and how the buyer is paying.
- Tick the items the buyer checked, and list anything that comes with the trailer.
- Use the tow match box to compare the weight rating with the tow vehicle.
- Check the preview, download the file, print two copies and sign both.
Common mistakes
- Copying a VIN from an old registration instead of from the trailer itself.
- Leaving out the weight rating, which the buyer needs to match to a tow vehicle.
- Not saying what brake and hitch type the trailer has.
- Forgetting to list the spare tire, ramps or other extras that were meant to be included.
- Assuming a trailer needs no title. Some states title trailers and others only register them.
- Selling a homemade trailer without checking what number your state wants on it.

Frequently asked questions
Do I need a bill of sale for a trailer?
In many places the buyer needs one to register the trailer, and some motor vehicle offices ask for it. Even where it isn't required, it records the price, the date and what you agreed.
Does a trailer need a title?
It depends on the state and the trailer's weight. Some states title trailers, some only register them, and some treat small trailers differently. Check your state's motor vehicle agency.
Where do I find a trailer's VIN?
Look for a metal tag or stamped number on the front of the frame or the tongue, and compare it with the title or registration. If the numbers don't match, sort that out before any money changes hands.
What is a weight rating (GVWR)?
It is the most the trailer is designed to weigh when loaded. It is usually on a sticker or plate. The tow vehicle must be rated to pull at least that much.
Do I need an odometer statement?
No. Trailers don't have odometers, so there is no mileage to record.
Can I sell a homemade trailer?
Often yes, but your state may want an inspection or an assigned number before the buyer can register it. Ask your motor vehicle agency what the buyer will need.
Should we both keep a copy?
Yes. Each person should keep a signed copy.
