Wyoming Bill of Sale for a Car
A bill of sale may be required for a private car sale in Wyoming, depending on the situation. County clerks require a bill of sale documenting the purchase price when a vehicle is bought from a private individual (for titling and sales tax under W.S. 31-2-103(a)(ix)), and a bill of sale in the exact statutory format of W.S. 31-2-104(h)(ii) is required to legally operate the vehicle for up to 60 days when the prior title is held by an auto auction or lending institution.

What a Wyoming car bill of sale must include
- Printed name of transferor/seller (and current owner if different)
- Date of sale
- Vehicle color, year, make, model, and vehicle identification number
- Printed name of transferee/buyer
- Sales price
- Statement of who holds the certificate of title and that a properly executed lien-free title will be provided within 30 days (statutory format for operating on a bill of sale)

- Transferor's signature, address, phone number, and driver's license/ID/dealer number
Wyoming follows the federal odometer disclosure rule on the title assignment (a separate odometer disclosure statement is required if the title lacks a conforming '(no tenths)' mileage statement), and the state title application MV-300A also captures the odometer reading; note the notarization Wyoming does require is of the seller's signature on the certificate of title itself, not of a bill of sale.

FAQ
Do you need a bill of sale to sell a car privately in Wyoming?
Sometimes. County clerks require a bill of sale documenting the purchase price when a vehicle is bought from a private individual (for titling and sales tax under W.S. 31-2-103(a)(ix)), and a bill of sale in the exact statutory format of W.S. 31-2-104(h)(ii) is required to legally operate the vehicle for up to 60 days when the prior title is held by an auto auction or lending institution.
Does a Wyoming car bill of sale have to be notarized?
No. Wyoming does not require a car bill of sale to be notarized for a standard private sale.
Is there an official Wyoming bill of sale form?
Wyoming does not publish a single official statewide car bill of sale form. Any document containing the required details — VIN, price, date, and both parties' names and signatures — is acceptable. Avoid third-party "form fee" services; the details, not the template, are what the state needs.
What should a Wyoming car bill of sale include?
At minimum: printed name of transferor/seller (and current owner if different); date of sale; vehicle color, year, make, model, and vehicle identification number; printed name of transferee/buyer; sales price; statement of who holds the certificate of title and that a properly executed lien-free title will be provided within 30 days (statutory format for operating on a bill of sale). Wyoming follows the federal odometer disclosure rule on the title assignment (a separate odometer disclosure statement is required if the title lacks a conforming '(no tenths)' mileage statement), and the state title application MV-300A also captures the odometer reading; note the notarization Wyoming does require is of the seller's signature on the certificate of title itself, not of a bill of sale.
What should I check before signing the Wyoming bill of sale?
Confirm the VIN on the document matches the dashboard and door-jamb VIN character-for-character, and check the vehicle's history first: the $9.99 CarWhere Full VIN Report shows open recalls for that VIN, plus complaints and service bulletins for the model and the original window sticker where available. Once you sign, the car — and its problems — are yours, so they're cheaper to find before you sign.
