Transferring NJ title to PA

Can't say for PA, but I once went through this in Texas and I ended up passing on the car. On my situation the buyer (current seller) had signed and dated the title, months ago, but had not transferred the title to his name. The title agency referred to this as "jumping the title" and they required the seller to put the title in his name before it could be sold. If the girl never signed or dated the title, you can simply date the title and act like you bought it from the original seller. Of course, if you need the original seller for anything (additional documentation or to be present for a notary, your SOL). I'd make sure you can get the title in your name by finding out what is required from your DMV before you buy the car.
