To do this, you will need to contact the lienholder and request a payoff statement. This statement will show you the amount of money you need to pay in order to release the lien. Once you have paid off the lien, you can then get the title transferred to the new owner.
It's important to note that if you sell a car with a lien on it without paying it off, the new owner will not be able to get a title for the car. This can make it difficult for them to sell the car in the future.
