If there is back registration and a ticket on a repo car does the finance company pay for both or just the back registraion in California?

NO.

no to what? no to the registration or no to the registration and ticket? they can't register the car if there is a ticket on it. so who would oay for it? the people who buy it at an auction or the finance company or the person who owned the car. someone has to pay for it. in California when a car is repoed or sold the title is transfered to the person who bought it (i.e. the finance company, cause they repoed it) and in turn, they are responsible for all fees associated with the car, so who pays for it? don't fell like the question was answered properly or accurately enought with just a no.
