A bill of sale is defined as a legal document made by the seller to a purchaser. It reports that on a specific date at a specific location and for a particular sum of money or other value received, the seller sold to the purchaser a specific item. When it comes to motor vehicles, the item is usually a car, truck, motorcycle, trailer, etc.
It is important to have a proper bill of sale in order to have proof of ownership and to protect yourself from potential legal action. As a purchaser you need to be able to prove that you have ownership of the new vehicle in order to register it and transfer the title. As a seller you must have proof of sale in case the vehicle is in any future accidents or involved in any legal activity.
Finally, it is important to get a professional bill of sale in order to ensure that you are covered. It is possible that a homemade or unprofessional bill of sale can be thrown out by a court or not accepted by the DMV so make sure you to get proper documentation and save yourself a world of hassle.
