* Contact your local DMV: The first step is to contact your local Department of Motor Vehicles (DMV) and request a duplicate title. The DMV may be able to issue you a new title if you provide certain documentation, such as your vehicle registration and proof of ownership.
* Contact the lienholder: If you have a loan or lease on your car, the lender or lessor will hold the title to the car until the loan is paid off. You will need to contact the lienholder and request a release of the title in order to trade in your car.
* Provide a power of attorney: If you cannot physically be present at the dealership to trade in your car, you may be able to give a power of attorney to someone else to act on your behalf. This will allow the other person to sign the necessary paperwork and complete the transaction.
It is important to note that the specific steps involved in trading in a car without a title may vary depending on your state and the dealership. It is a good idea to consult with the DMV and the dealership in advance to find out what documentation and steps are required.
