how are you going to prove who signed it.
prove the guy is who he says he is.
find the guy when he scams you
this aint like your signing something between to people that you know this is from one side of the country to the other.
The key is to know who you are buying from. If you cant trust anyone one on this fourm than you better start buying local. If some one is gonna scam you there aint nothing you can do about it but make sure you paid for it the right way on PP and did everything right so you can get your money back. What is paypal gonna do when they see that NOTHING you could have made that and had your friend sign it. Same with court really unless there is flim of the guy signing it while holding his ID , Birth Certificate and his SS card.
