Hey guys, I had a quick question. I am supposed to be mediating a family member who is selling their car to someone. I know both parties personally, so the issue isn't with that. My question is, the vehicle is currently titled in Delaware, but the new owner lives in PA. I know that the new owner can just go to a tag store and do MV-4ST to transfer the ownership to them. My question was, I know PA has a gifting form so that the new owner does not need to pay sales tax on it, but since its a DE title, is there a Delaware form I need to fill out?
I know that if you do the gifting form through PA, you do not need to file the Use tax that is something like $6 on top of the sales tax Which would be about $600 (selling price is $10,000). Any ideas on what I should look for? I am looking to do this next Monday, so there is some time.

Also, what boxes on the title need to be signed by the original owner to transfer?

Thanks guys!
