For the purposes of this website, we’re interested in bill of sale documents for the private sale of used vehicles.
What is a Bill of Sale Used For?
A bill of sale is used to document the transaction and act as proof of transfer and purchase when selling a used vehicle.
In a used car sale between private parties, a bill of sale is a key document to protect both the buyer and the seller.
A bill of sale should be used any time you sell or buy any item of significant value.
How Does a Bill of Sale Work?
A bill of sale is a document that benefits both the buyer and the seller of a used vehicle.
For one, it serves as a receipt of the transaction.
As the seller, a bill of sale protects you from liability. If the buyer claims something other than what was agreed upon in the transaction, you have the signed bill of sale to protect yourself.
As the buyer, the signed bill of sale helps protect you from a seller who tries to back out of a transaction or alter the deal after the fact.
Do I need a Bill of Sale when Buying a Used Car?
While a bill of sale is not always required by every state Department of Motor Vehicle when buying or selling a used car, it is always a good idea.
As the buyer, you should definitely retain a signed copy of a bill of sale for the vehicle you are buying.
The seller should keep a copy for their records too.
Even when it is not a requirement to transfer the vehicle, it can help:
- Eliminate any potential disputes that arise.
- Provide proof of the sale and the agreed upon sale price.
- Provide a paper trail of the chain of ownership.
Additionally, a bill of sale is extremely valuable in cases of purchasing an old vehicle where the title may be lost and the previous title holder may be deceased.
