An Indiana general bill of sale is a proof of purchase document held onto by both buyer and seller of a private transaction and should be kept by the seller in their personal records. The completed document will state the purchase price and date of sale of the item being sold, and will include a short description of the property (e.g., the type of item, year it was made, color, manufacturer, etc.). Both parties are required to sign the document, and may notarize the form if they so wish. If the form is notarized, both parties will be required to prove their identity to the notary public. Once the bill of sale has been completed, the item will be considered paid for with ownership transferred to the buyer.
