Is a bill of sale required in Wyoming?

Not for an ordinary sale where the seller signs the title over; the assigned title is what lets the buyer drive for 45 days and then title the vehicle at the county clerk. A bill of sale becomes essential when the title is held by a lender or an auto auction: then a bill of sale in the statutory format lets the buyer drive for 60 days.

Wyoming Bill of Sale — Free Template & Generator

Wyoming is unusual in writing a bill of sale’s wording into statute. When the seller’s title is held by a lender or an auction, a buyer may drive for 60 days on a bill of sale — but only one that follows the format in W.S. 31-2-104(h)(ii), which WYDOT reprinted for county clerks in September 2023. On an assigned title, the grace period is 45 days.

WYDOT — Titles, Plates and Registration

How this document fits Wyoming’s paperwork

Official form: WYDOT does not require a particular bill-of-sale form for an ordinary sale with the title in hand; titles and liens are processed by the county clerk in the county seat of the buyer’s county of residence. For the case where the title is held by an auction or lender, the statute prescribes the bill of sale’s wording, quoted below.

With the title in hand, the assigned title is the transfer. The generated bill of sale is the record of price, date, odometer and terms, and the buyer has 45 days of driving on the assigned title before registering at the county clerk. If a lender or auction holds the title, the buyer’s 60 days of driving depend on a bill of sale in the statutory format. Put the W.S. 31-2-104(h)(ii) paragraph quoted above in the “Additional terms” field, naming who holds the title and promising a lien-free title within thirty days.
