Trailer Bill of Sale Form

A Trailer Bill of Sale contains the pertinent information to prove a person or company paid money to acquire a pull-behind vehicle designed to be hauled by a car or truck. Like automobiles, state law often requires trailers to be registered if they will be used on public roads. During registration, the DMV will require proof of ownership, which the bill of sale form provides. The form can be used for trailers of all makes, models, and sizes, including those that carry commercial equipment, boats, cars, atvs, snowmobiles, motorcycles, landscaping tools, cattle, and more.


What is a Trailer Bill of Sale?

A trailer bill of sale is a two (2) page document that serves as the last step in the trailer-selling process. It can be used for transactions involving cash, credit, check, or trade. It contains three (3) major sections; 1) identification of the parties and sale price, 2) information on the trailer, 3) and everyone’s signatures. The standard formality involves the buyer keeping the bill of sale for their records. If desired, a copy can be made and provided to other parties, such as the seller.

Is it Required?

A bill of sale isn’t necessarily required, although completing one is a good decision. If the buyer doesn’t need to register their trailer or they have an alternative means of proving ownership, they can get by without one. However, it is a widely accepted document that provides clear proof that the deal occurred. Additionally, it acts like a receipt, letting the owner (and any future owners) know exactly what was paid for the trailer, its specs, VIN, and when the owner took possession of it.

How to Register a Trailer

The process and requirements for registering a trailer is state-specific. While one state may require boat trailers to be registered, another state (like Alabama), may not. Head to your local DMV office to understand the steps you will need to take. Alternatively, you can go online to your state’s DMV website, where they will list the fees and paperwork required. Once the buyer obtains the bill after paying for the trailer, they will need to do the following:

Step 1 – Gather Paperwork

The individual registering will need 1) proof of ownership, 2) the title (if applicable), an 3) cash to pay for the associated fee.

Step 2 – Go to the Nearest DMV

Go online to locate a DMV near you. There are typically one or more offices in every county.

Step 3 – Pay the Fee

The fee will range anywhere from $5 to $25+ dollars, depending on the type of trailer and whether it is used for personal or commercial hauling. Credit cards are not always accepted – bring cash to play it safe. You will then be given a plate. Attach it to the trailer in a clearly visible manner in a way that doesn’t obstruct brake or back-up lights.

Step 4 – Re-register Yearly

The buyer will need to re-up their trailer registration if they intend to use it. If it sits un-used, it does not require registration. The timeframe for renewals is dependent on the state or county. Some mandate yearly registration, while others have bi-yearly requirements. After the first in-person registration, subsequent registrations can often be completed online.
