A Wyoming motor vehicle bill of sale is a document demonstrating that a motor vehicle has been legally sold in the State of Wyoming. The bill of sale will record identifying information about the seller and the buyer, a description of the vehicle, and the terms of the transfer of ownership. This document may be used as part of the process of registering a vehicle or in filing other types of applications. The uses for bills of sale will vary depending on the county where the vehicle buyer resides.
Signing Requirements – Most counties require the seller’s signature (only) and to be in front of a notary public.

Registering a Vehicle
A vehicle purchased by a Wyoming resident must be registered to be used on Wyoming roads. (Temporary workers in the state for fewer than 120 consecutive days must acquire a temporary registration from the state of Wyoming.) For vehicles purchased at a dealership, the dealer will generally handle the filing of titling and registration forms, but for transfers of ownership between private parties, the buyer must act to register. Registration is a matter handled at the county level in Wyoming, so the amount of time a buyer has to register, the duration of registration, and the methods of renewal will vary. Buyers should consult the local county treasurer’s office for more information.
Where to Register
Registration for a recent vehicle buyer is generally handled at the Treasurer’s Office (Directory) in the buyer’s county of residence.
