Sell your car in Wyoming — one notarized signature from done
Wyoming keeps car selling old-school: the title does all the work, a notary makes it official, and the county clerk's office is where everything lands. There's no smog test, no safety inspection, and no state paperwork after the handshake — which means once you understand the notary step, selling here is about as clean as it gets.

How to sell a car in Wyoming
- 01Check your title's issue date and the word between the names. Wyoming decides who signs by that word and by the date the title was issued. On a title issued on or after January 1, 2020, names joined by OR, or by no word at all, let one owner sign alone. AND, or joint tenancy with rights of survivorship (JTWROS), means every owner signs. On a title issued before 2020, every owner signs whatever the word. Nobody signs for anybody else.
- 02Sort out a lost or financed title at the county clerk. Title lost? The county clerk that issued it, not the one where you live now, replaces it for $15 on that county's own notarized affidavit, such as Laramie County's duplicate title application (020-021). The old title is void once the new one issues. A Wyoming lien release also happens at the county clerk, the same office that recorded the lien. If your buyer is borrowing and your title is still with your bank, their lender may use a Transitional Ownership Document (MV-141), so get your payoff figure and release date in writing first.
- 03Branded title? Get the buyer's signature on MV-602 before the money. In Wyoming a private owner, not only a dealer, must disclose a salvage, rebuilt or flood brand before the sale on the Branded Title Disclosure Statement (MV-602), and the buyer signs to say they were told. Skip it and the buyer can undo the sale in writing up to 30 days after their new title issues. WYDOT can also brand a car from national title records even when your Wyoming title shows no brand.
- 04Fill in sections 1 and 2 while the buyer is with you. The back of the Wyoming title numbers its own four sections. Write the buyer in section 1 and the odometer reading in section 2 before anyone signs, because a county clerk's office will not notarize an open title. The reading is required, in whole miles with no tenths, for a model year 2011 or newer until it has 20 years of service. A 2010 or older model is exempt: leave the box empty rather than writing "exempt". The buyer signs the line that acknowledges the reading.
- 05Sign section 3 in front of a notary, with your ID. Section 3, the Seller's Transfer, holds the sale price, the date of sale and your promise that the only liens are the ones on the front, and it is marked MUST BE NOTARIZED. Sign it in front of the notary. A title signed at home and carried in is refused, and every owner who has to sign must be in the room. No correction fluid and no writing over: the title is void if altered, and altering it to cheat is a felony. The buyer's section 4 has no notary. A Wyoming bill of sale is a county form, not a state one; Natrona County's has its own notary block, so sign it at the same sitting.
- 06Plates off at the sale, unless the buyer is family. Under W.S. 31-2-214 the registration ends when the title changes hands, and you must remove the plates immediately. Wyoming gives no refund. Instead, within 60 days of getting another vehicle, the county treasurer can move your registration number onto it with credit for the unused months. The buyer drives home on your signed title, which is legal for 45 days. Selling to your spouse, child, parent, brother or sister, or between joint owners? The treasurer re-registers it for $4 and the plates stay on for the rest of the registration year. A plate missing? Replace it on MV-405 before you set a sale date.
- 07Keep your own proof, because there is nothing to file. Wyoming has no notice of sale and no release of liability, and the Wyoming DMV is told nothing. Your notarized signature is the dated record that the car stopped being yours. Photograph the finished back of the title before it leaves your hands, keep the bill of sale, and write down the plate numbers and what you did with them. Keep your insurance running while your registration number is still waiting to move to your next vehicle.
- 08Your buyer has 45 days at the county clerk. The buyer finishes the Wyoming title transfer. They sign section 4, the purchaser's application on the back of the title, and take it to the county clerk of their own county within 45 days with the $15 title fee. Wyoming vehicle sales tax is paid to the county treasurer, 4% state plus their county's share, within 65 days of the sale, and the clerk won't release the new title without that receipt. The separate MV-300A title application is only needed when the back of the title can't carry it, or the car comes from another state.

What Wyoming requires when you sell
| Notary | Wyoming is one of the few notary states, and the notary is for the seller: your signature on section 3 of the back of the title must be made in front of one. The buyer's application in section 4 has no notary block. How many owners sign depends on the title: on one issued since January 1, 2020, names joined by OR (or no word) let one owner sign alone, while AND or JTWROS needs everyone; on an older title every owner signs. A county clerk's office won't notarize an open title, so the buyer's name and the mileage go in first. source |
|---|---|
| The title form | There is no separate assignment form — ownership transfers on the back of the Wyoming title itself, in four numbered sections. The odometer reading goes in section 2 for model year 2011 or newer until the vehicle has 20 years of service; model year 2010 and older is exempt. The buyer's application is section 4, so most private sales never need the separate MV-300A. The buyer then applies at their county clerk's office; a new Wyoming title costs $15. source |
| Bill of sale | No state form. Wyoming publishes no statewide bill of sale. County clerks publish their own, and Natrona County's is notarized. Several clerks ask for one, and the sales tax counter reads it for the price, but it is a receipt, not the transfer: the car only changes hands on the title. The one wording in state law is for a sale where a bank or auto auction holds the title. See our Wyoming vehicle bill of sale page for Natrona County's form. source |
| Lost your title? | A duplicate costs $15 from the county clerk that issued the original, by mail or in person, on that county's own affidavit, such as Laramie County's 020-021. All owners must sign the duplicate application before a notary. A lender still on the record signs the same form to have its lien carried onto the duplicate, and the old title is void once the new one issues. source |
| Protect yourself after the sale | Wyoming has no release-of-liability filing for private sellers. Your protection is the notarized transfer, pulling your plates, and keeping a dated bill of sale — Natrona County's clerk publishes a free bill of sale form for exactly this. source |
| License plates | Plates belong to you, not the vehicle. Take them off before the buyer drives away — you can move the plates and any remaining registration credit to your next ride through the county treasurer. source |
| Sales tax | The buyer's problem, not yours. Wyoming car sales tax on a private sale is collected by the buyer's county treasurer before first registration: 4% state plus the buyer's county share, due within 65 days of the sale. After that, interest runs at 1% a month and the treasurer adds a $25 civil fee, rising after day 75 to the greater of $25 or 10% of the tax. The clerk won't release the new title without the tax receipt. source |
| Inspections | None. There is no Wyoming emissions test and no safety inspection when you sell. The only check in the titling law is a $10 VIN inspection by a Wyoming law enforcement officer, and only for a vehicle with an out-of-state title, a homemade, rebuilt or kit vehicle, or a Wyoming bonded title. A Wyoming-titled car sold in Wyoming needs none of it. source |

Asked by Wyoming sellers
Does Wyoming really require a notary to sell a car?
Yes, for the seller. Your signature on section 3 of the back of the title, the Seller's Transfer, must be made in front of a notary. The buyer's application in section 4 is not notarized; they sign it under penalty of perjury. Who has to sign depends on your title: on one issued on or after January 1, 2020, owners joined by OR (or no word) can sign alone, while AND or JTWROS means everyone signs; on an older title every owner signs. A county clerk's office won't notarize an open title, so write in the buyer's name and the mileage first. The classic mistake is signing at the kitchen table: a notary can only acknowledge a signature made in front of them, and the fix may be a $15 duplicate.
Do I have to notify the state after I sell my car in Wyoming?
No. Wyoming has no notice-of-sale or release-of-liability filing for private sellers. Your protection is the notarized title transfer, taking your plates with you, and keeping a dated bill of sale — several county clerks, including Natrona County's, publish a free bill of sale form for the purpose.
What happens to my license plates when I sell?
They come off and go home with you. Wyoming law ends the registration at the sale and says you must remove the plates immediately. There's no refund, but within 60 days of getting another vehicle you can move the registration number onto it at your county treasurer, with credit for the unused months. The one exception is a sale between joint owners or to your spouse, child, parent, brother or sister: the treasurer re-registers it for $4 and the plates stay on for the rest of the registration year.
I lost my Wyoming title — can I still sell?
Yes, after a $15 duplicate from the county clerk that issued the original, not the county you live in now. Every owner signs the duplicate application before a notary, and the process works by mail or in person. If a lender is still on record, it signs the same form to have its lien carried onto the duplicate. Once the duplicate issues the old title is void, so if it turns up later, don't sign it. Build in a little lead time and it's painless.
