Once you’ve signed the back of the title over to the new owner, you should be set! They are now the legal owner of the car, and you shouldn’t face any issues of ownership.
It is important to treat any title transfer like a sale, where you are the seller and the new owner is the buyer. The title of a vehicle is proof of ownership and contains other information about the vehicle, so it is important that your title transfer is done correctly and smoothly.
Hope the title transfer goes smoothly!
