Title procedures vary by state and local governments, but most of the time if you have financed your new car, the title will be kept by the lender until you have paid the car off.
The lender will also be listed as a lienholder on the title. This ensures that if you were to try to sell the car, the lender would be paid off before the title could be transferred to the new owner.
If the new car is not financed, the seller will provide the title once you’ve paid them. Then you’ll complete your registration and tags with the DMV. You will need to show proof of insurance to get tags and registration for the vehicle.
