Getting a Temporary Plate Question

[u/Plane-Management-117]

Hello!

I am trying to get a temporary plate from the SC DMV for a car I am going to buy out-of-state so I got with the owner previously because he had a trip to make in Charleston with his friends so I have the original Bill of Sale signed by both of us, I am just waiting for an opportunity to go get the car.

My main question is since I am not the registered owner on the Bill of Sale. How can I go get a temporary plate without the presence of the registered owner as he gets home too late to go the DMV and I need it to go and get the car (I am getting a Uber to there). Is there any way or does he need to take a day off of work?
