Fill Out a South Dakota Bill of Sale Online in 2026

A South Dakota bill of sale is a written document that records the private transfer of ownership of personal property—such as a motor vehicle, boat, or other asset—from a seller to a buyer. It documents the key transaction details: names and addresses of both parties, a description of the item, the sale price, and the date of the sale.

South Dakota does not have a single mandatory state-issued bill of sale form for all transactions. Any clearly written document including the essential details is legally recognized. For motor vehicle title transfers, the South Dakota Division of Motor Vehicles may use the stated purchase price from the bill of sale to calculate motor vehicle excise tax.

A South Dakota bill of sale is used to formally document the transfer of personal property and protect both parties in a private sale. Specifically, it is used to:

• Document the transfer of personal property (vehicle, boat, firearm, equipment, or other items) from seller to buyer
• Establish the agreed purchase price on record — South Dakota DMV uses this to calculate applicable sales tax, use tax, or registration fees when the buyer applies for a new title
• Protect the seller from future liability related to the property after the sale date
• Give the buyer proof of ownership pending receipt of a new title
• Serve as evidence in any dispute about the terms, price, or condition of the item at the time of sale
• Support insurance documentation — the buyer can present the bill of sale to their insurer as proof of acquisition and value

A complete South Dakota bill of sale should include the following information:

• Full legal name and current address of the seller
• Full legal name and current address of the buyer
• Detailed description of the item being sold — for vehicles: year, make, model, color, body type, and VIN; for other property: a clear description with any serial number
• Agreed purchase price
• Date of the transaction
• Current odometer reading at the time of sale (required by federal law for all motor vehicle transfers)
• Signatures of both the buyer and the seller

South Dakota does not legally require a bill of sale for all private property sales. For vehicle title transfers, the South Dakota DMV may require documentation of the purchase price to calculate the 4% motor vehicle excise tax. A bill of sale provides this documentation.

For boat and vessel transfers, the South Dakota Game, Fish and Parks department may also request a bill of sale as supporting documentation.

No. South Dakota does not require a bill of sale to be notarized for it to be valid. A South Dakota bill of sale is enforceable without notarization for personal property transactions, including motor vehicles.

Notarization is optional and not required by the South Dakota DMV for vehicle title transfers. Either party may add it for extra legal assurance.

A South Dakota bill of sale has no expiration date. Once both parties sign it, it becomes a permanent legal record of the transaction. Neither party needs to renew or re-execute the document—it remains valid indefinitely as long as it accurately reflects the completed sale.

Both the buyer and the seller should keep their signed copies for their personal records. For vehicle transactions, retain the bill of sale until the South Dakota DMV has processed the title transfer and issued a new title in the buyer's name. The document may also be needed as proof of purchase for insurance, tax verification, or future ownership disputes.
