Wyoming Bill of Sale Requirements & Free Form

This page covers how a bill of sale fits into a private vehicle sale in Wyoming, where titles are processed by county clerks rather than a central motor vehicle office.

Wyoming requirements

  • Wyoming titles and lien filings are processed through the local county clerk office in the county seat of the county of residence, not through a statewide DMV counter.
  • Under W.S. 31-2-104 the seller endorses an assignment and warranty of title on the certificate, with a statement of all liens, and that assignment must be signed and dated by the owner before a notarial officer and acknowledged. The notarization applies to the title assignment itself.
  • The buyer then presents the certificate to a county clerk and applies for a new certificate of title within the time periods in W.S. 31-2-201(a)(ii), which sets 45 days for an ordinary private transfer and 60 days for several dealer related transfers.
  • Wyoming does not require a general bill of sale for every private sale. A statutory vehicle bill of sale form appears in W.S. 31-2-104(h)(ii) for the narrower case where the transferor is a vehicle auctioneer or the title is held by a bank or other financial institution and will be delivered within 30 days. Our general bill of sale is a general purpose alternative for the ordinary private sale and for non vehicle property.
  • Record an accurate odometer reading on the assigned title rather than an estimate, in line with the federal disclosure rule.
  • Confirm the current title fees, sales tax handling and any county specific paperwork with the county clerk and county treasurer where you live before you file.

Frequently asked questions

Does anything have to be notarized in a Wyoming private vehicle sale?

Yes. W.S. 31-2-104 requires the seller's assignment and warranty of title on the certificate to be signed and dated before a notarial officer and acknowledged. The bill of sale itself is a separate record and the statute does not require it to be notarized.

Where do I transfer a vehicle title in Wyoming and how long do I have?

At the county clerk office in the county seat of your county of residence. W.S. 31-2-104 sends the buyer to a county clerk within the periods set by W.S. 31-2-201(a)(ii), which allows 45 days for an ordinary private transfer.
