How Do You Register For Sale By Owner Cars in Wisconsin?
In Wisconsin, you have to register your car with the DMV within 30 days of purchasing it. You can do this online or in person at any DMV office. If you buy from a private owner and don't have proof of ownership (such as a title), then you will need to get an affidavit from the seller stating that they no longer own the vehicle and that they are selling it without any liens on it.
