Wisconsin Seller Guide: How to Sell Your Used Car Privately Without the Guesswork Wisconsin Seller Guide: How to Sell Your Used Car Privately Without the Guesswork

Selling a vehicle privately in Wisconsin allows you to maximize your return on investment and connect directly with local buyers. To successfully navigate the private auto market, you need to fully understand the particular laws regarding your state; prepare accordingly; and follow a strategic plan for identifying the best buyer for your car.

This extensive guide will detail every aspect of your private sale from start to finish in order to help you sell your car as smoothly as possible. You will learn what documents you need to sell your car legally; how to interact with potential buyers safely; and how modern services like the KarKiosk platform will help simplify the entire transaction, beginning with the listing and ending with handing over the keys.

Required Documents and Paperwork for Sellers to Complete in Wisconsin

The most important component of completing the sale of your car privately is the proper completion of all the necessary paperwork. There are specific documents that you will need to gather prior to listing your car, which will help demonstrate your professionalism and provide potential buyers with assurance that their purchase is legitimate.


Title Certificate

The Certificate of Title serves as the main legal document that identifies you as the legal owner of your car. To complete the sale of your car, you must transfer to the buyer possession (or ownership) of your car's title by completing the Assignment of Title section located on page 2 of the Certificate of Title.

To complete this document, it is important that you write the buyer's full name and address, the odometer reading, and the date the sale occurred. In addition, you must also include the sale price of the car, as well as your signature and printed name in the same way it appears on the front of the Certificate of Title. You cannot use corrective fluid or cross out errors on this document.Modifying the Title Can Void the Title.

Any alteration will result in the title being considered void and you will be required to get a new title before you may continue to sell the vehicle. If you have misplaced your title or have had it stolen or damaged, you cannot legally sell your vehicle within Wisconsin until you apply for a replacement title using Form MV2119 with the Wisconsin Department of Transportation (WisDOT). If there is a lien on the vehicle due to an outstanding auto loan, you must pay the loan in full so that the lienholder releases the lien to allow you to sell and transfer a clear title.

Get a Bill of Sale

Although there is no requirement for creation of a bill of sale for auto sales, it is highly recommended for private auto sales to create one. A bill of sale is essentially a legal receipt of your auto sale that lays out the specific terms of the agreement. You should use the official state form MV2928 in drafting your bill of sale, as it contains the formal legal descriptions of the vehicle including year, make, model, and vehicle identification number (VIN).

The bill of sale should also specify the agreed upon sale price, the date of sale, and the signature of both you and your buyer. A signed and dated copy of the bill of sale should be retained by you in the event that there are any disputes after your buyer has taken the vehicle.

Complete Release of Liability Form

After the keys have been turned over, you want to ensure that you are no longer legally liable for the vehicle. To eliminate your liability for the vehicle, you must submit a Seller's Notice of Sale (which is also referred to as a Release of Liability) to the Wisconsin Department of Transportation reporting that you have sold and no longer own the vehicle. 

This essential step protects you from having to pay for parking tickets, towing fees, or any liability from the new owner until they have registered the vehicle in their name.

Removing Your License Plate

In Wisconsin, the license plate belongs to the seller and not the vehicle itself. The license plate must be removed before giving possession of the vehicle to the buyer. If a buyer/borrower drives your vehicle with your license plate attached, you will be liable for any violation they incur. If you remove your license plate, you can transfer it to another vehicle you own, or you can properly dispose of it according to state law.

Steps to Follow When Selling a Vehicle Privately

To sell your vehicle, you need to take it through a specific series of steps. Using a logical sequence of actions will help make your car more attractive to potential buyers and help you close the deal in a timely manner.

Step 1: Prepare and Price Your Vehicle

First impressions are important and your vehicle should be thoroughly cleaned — inside and out. Personal items should be removed and it may be wise to consider having your vehicle detailed by a professional. Next, you will need to conduct research on the current market value of your vehicle.

Use KarKiosk to estimate what your vehicle's Make, Model, Year, etc. is worth. By pricing your vehicle competitively, you are less likely to have it sitting on the market for an extended period of time, and you will be more likely to receive a fair amount of money for it.

Step 2: Create a Good Listing

When listing your vehicle for sale, enter your vehicle's VIN or license plate number on the platform of your choice. This will help you autofill the different vehicle details so you do not make any mistakes when entering data. Write a good, honest description of your vehicle.Describe what makes your vehicle special: Major features, recent maintenance, and any unique selling points should all be highlighted and disclosed when they exist. Minor wear and tear should also be explained frankly; if you do this well enough, then the buyer will be more likely to trust your vehicle.

Step 3: Taking Good Pictures & Videos

Visuals are a big part of selling a vehicle. Go to a well-lit location where you can take good pictures of your vehicle from different angles. Good pictures should include: Exterior views of each side of the car, interior views of the dashboard and the car's front seats, and good pictures of the engine bay and tires. A 30-second video of your vehicle running or showing the interior will increase your chances of a successful sale, particularly with long-distance buyers.


Step 4: Responding to Offers & Setting Up Test Drives

Once your listing has received interest, you can expect to receive offers and other inquiries about it. Keep a record of all inquiries and offers. When you have a serious buyer, set up a time for the buyer to see and drive the vehicle. Make sure to meet in a safe, mutually agreed upon location.

Step 5: Finalizing the Sale

After reaching an agreement on the price, follow through with all of the previous suggestions regarding paperwork. Be sure you have the buyer's form of secure payment. After signing the title over and giving the bill of sale, remove your license plate, and give the buyer the keys. Don't forget to cancel your auto insurance for that car.

Safety Considerations for the Transaction

The most important thing to keep in mind when selling your vehicle privately is that your personal safety and financial security must always be your first consideration.Important Steps To Take When Selling Your Car

Verify Valid Driver's License

During the test drive, request identification (a valid driver's license) from potential buyers. Take a snapshot or write down their ID number. This will show that they have the proper credentials to drive the vehicle during the test drive and have proof/documentation of identity for both of you and the seller.

Meet In Safe Locations

Do not invite strangers to your home. Always meet at a busy public place that is well lit. Some examples include a grocery store or bank parking lot, or designated areas for safe transactions at local police departments. Bring a friend with you for the purpose of test driving and/or examining the vehicle.

Collect Payment Securely

A personal check has the potential of bouncing due to insufficient funds. Instead, request cash, a cashiers check, or direct wire transfer if your vehicle is inexpensive. If you accept a cashier's check, have the buyer meet you at their bank so you can watch the teller issue the check. Otherwise, use a third party payment service that will securely hold funds until all documentation is signed.

KarKiosk Simplifies Your Sale

KarKiosk is a specialized online marketplace that has been developed to help eliminate much of the frustration associated with private sales of cars in Wisconsin. By using KarKiosk's features, you have more buyer exposure and can complete sales quicker.

Free Vehicle History Report

When marketing a car you want to create transparency. Providing a free vehicle history report to potential buyers will help establish credibility and show the buyers you are a trustworthy seller providing a dependable vehicle.

FAQs about Cars for Sale by Owner

Is it necessary for a notary to be involved in transferring a title in WI? toggle

The state of WI does not require notarization when signatures are present on a vehicle title for a regular or typical private parties sale; however, you will want to complete the transfer section correctly and sign that section of the title.

Does a private seller have to collect sales tax when selling an automobile? toggle

No; private sellers do not collect sales tax from buyers. The buyer will be responsible for paying to the Wisconsin Department of Transportation (WisDOT) directly for 5% state sales tax and any applicable sales tax imposed by their local governmental units or counties when they apply for titling and registration of their newly acquired vehicle.

What happens if I lose my title? toggle

If you can't find the vehicle's title, you can not legally sell your car in WI without the title. You must acquire a duplicate title by filling out Form MV2119 and submitting it to WisDOT. Further, you must satisfy any outstanding liens on the title before ownership can be transferred to a new party.

Does my car need an inspection or emissions test before I sell it? toggle

In Wisconsin, you do not have to have either a safety inspection or emissions testing completed in order to sell your vehicle to an unrelated party. Since the seller will usually sell the vehicle "as is," there is no guarantee the vehicle will meet the manufacturer's standards for operation.
