I think the best course of action is to discuss this with the State of South Carolina Department of Motor Vehicles. They should be able to tell you exactly what you would need to present to get the proper title.
Folks on here will respond with what their state might require but that is their state not South Carolina.
Go to the source and get the correct information you need
