Wyoming Bill of Sale

Wyoming does vehicle paperwork the county way: clerk for the title, treasurer for the tax, notary for the signatures — and a notarized bill of sale that legally keeps the buyer driving for 60 days while the title catches up.

The Wyoming answer

Two county offices, one notary, sixty days of grace.

A Wyoming transfer walks through the county clerk (title, with the seller’s notarized signature) and the county treasurer(sales tax and plates) — there is no statewide DMV counter and no statewide bill of sale form. What Wyoming does standardize is the bill of sale’s job: notarized, it becomes a legal 60-day operating document when the title is still with a lienholder bank. That bridge is unique enough that buyers here should insist on the notary even though a plain bill of sale would otherwise do.

Out-of-state titles meet Wyoming law enforcement.

Bringing a vehicle in on another state’s title? Wyoming requires a VIN inspection certified by a Wyoming law-enforcement officer before the county clerk will issue a title — schedule it before your county trip, not after. And don’t sit on the tax: the treasurer expects payment before first registration and within about 65 days of purchase, with the penalty jumping to the greater of $25 or 10% of the tax owed after that, plus interest that accrues monthly.

Not legal advice. County practices vary — your clerk and treasurer are the authority. Facts verified against WYDOT and county sources in July 2026; official links in our 50-state requirements table.
Cowboy State questions

Wyoming specifics, answered.

Why does every Wyoming county seem to have its own bill of sale?

Because titling is county-run. Wyoming has no single statewide bill of sale form — county clerks issue titles, county treasurers collect the tax, and many counties publish their own bill of sale PDFs. Any bill of sale works if it carries the VIN, price, date, and signatures — notarized if you want it to double as your temporary operating document.

Can I really drive on just a bill of sale in Wyoming?

Yes — for up to 60 days, if it's notarized. When the title isn't available at sale time (commonly because a lender still holds it), Wyoming law lets the buyer operate the vehicle on a notarized bill of sale while the paperwork catches up. It's the state's built-in bridge, and the reason a Wyoming bill of sale is worth notarizing even when nothing else requires it.

What gets notarized in a normal Wyoming transfer?

More than most states: the seller's signature on the title must be notarized, and the buyer's application for title is signed before a notary too (titles issued since 2020 relaxed the multi-owner signature rules somewhat). Between the clerk's office and the treasurer's office, plan for two county counters and a notary.

What about out-of-state vehicles and deadlines?

Every vehicle arriving on an out-of-state title needs a VIN inspection certified by a Wyoming law-enforcement officer before titling. Sales tax (4% state plus the county's 1–2%) is due to the county treasurer before first registration and within about 65 days of purchase — after that the penalty is the greater of $25 or 10% of the tax, plus monthly interest.
