If my car had been purchased new from a New Jersey dealership what would I need as proof of ownership?
You would need the Manufacturer’s Certificate of Origin, and the dealer's bill of sale
ok, and what will I need to have with me to register the car?
Before you visit a DMV office to register your vehicle, you should complete the Document Guide to make sure you bring the correct documents with you. The requirements to register an out-of-state vehicle are generally the same as to register and title vehicle in New York.
