Can you get in trouble for selling a car to private party that still owe money on?

It depends on the state and specific laws. In general, it is not illegal to sell a car that you still owe money on as long as you disclose this fact to the buyer. However, there may be legal consequences if you do not disclose this information or if you transfer ownership of the vehicle without first satisfying the lien. It is important to consult with an attorney or your local motor vehicle department to determine the specific laws and regulations in your state regarding the sale of a car with an outstanding loan.
