Name(s) on Tesla Reservation for Co-Ownership?

[RidgeRacerJM]

When reserving the Tesla Model 3, will both parties need to sign the reservation agreement? Or can the 2nd party be added as a co-owner during the configuration process months later? Or if there are Model S and X owners who read this, how did you go about this?

Thanks!

I think when you fill out the "title" information you can add anybody as co-owner. The same is true of any loan you may take. But if I recall my Model S configuration process , there is nothing about a second owner.
