How do I change registration for a car that is out of state?

My uncle he lives in Utah and he give me a car but he still making payment so the car will be under his name. I want to know how to change a car registration in ca. Do my uncle have to be in ca to register the car for me or I could register it by myself?|||If he%26#039;s still making payments on the vehicle, it isn%26#039;t his to give away. If your name isn%26#039;t on the title, you aren%26#039;t going to be able to register the vehicle.
