If you have agreed to buy or sell a trailer, you will want to sign a bill of sale as proof that the transaction has been completed. We've put together a guide to what is included in the document and where you can find a free template online to help you write it.

What is a bill of sale (trailer)?

A bill of sale for a trailer acts as a receipt for the sale and purchase of a trailer that can be towed by another vehicle, including a boat trailer or flatbed trailer. A bill of sale can be used to document a variety of purchases, so the bill of sale you need will contain specific details of the trailer.

A bill of sale is subject to state law in Australia. New South Wales replaced bills of sale with security interests under the Security Interests in Goods Act 2005, so a bill of sale must be registered as a security interest.

Bill of sale (trailer) vs sale agreement.

A bill of sale for a trailer includes the key information of the transaction, including the details of the buyer and seller and details of the trailer.

A bill of sale is effective as a receipt that both parties can keep to prove that the transaction was agreed to and completed. It can be used to register the transfer of the trailer's registration to the new owner with the relevant licensing agencies.

A bill of sale can also be used to prevent unwanted liability if something goes wrong with the trailer and guard against fraud. If witnesses sign the document it can be used as evidence if there are legal issues raised concerning the sale in the future.

A bill of sale is more effective than an invoice because it's issued after the buyer has paid and carries legal weight.

How do I write a bill of sale (trailer)?

A bill of sale for a trailer is a simple document that should be written in clear language. It is a proof of purchase rather than a contract so does not need to include all the details of the sale agreement that it accompanies.

It should outline the agreement clearly in terms of the details of the trailer and any warranties or liabilities and express the intentions of each party so that they know where they stand and can refer back to the document as needed.
