Fill Out a Wyoming Bill of Sale Online in 2026

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

Wyoming does not publish a single mandatory state-issued bill of sale form for all transactions. Any written document that includes the essential transaction details is legally recognized. For vehicle title transfers, Wyoming Department of Transportation (WYDOT) uses the purchase price from the bill of sale to calculate county sales tax.

A Wyoming 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 — Wyoming county treasurer 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 Wyoming 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

Wyoming does not legally require a bill of sale for all private-party sales. For vehicle title transfers, the Wyoming county treasurer uses the purchase price from the bill of sale to calculate county sales tax. Without a documented price, the tax may be assessed on the vehicle's book value.

A bill of sale is also recommended for boat and personal property transfers to establish a clear record of the ownership change.

No. Wyoming does not require a bill of sale to be notarized. A Wyoming bill of sale is legally valid without notarization for most personal property transactions, including motor vehicles.

Notarization is optional and not required by WYDOT or Wyoming state law. Either party may choose to include a notary for added assurance.

A Wyoming 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 Wyoming county treasurer 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.
