In the US the only things that require a witness is the deed and the mortgage if you get one. Terms of the sale are just signatures.
I sold a house having never even physically met the guy who sold it for me. They sent me a stack of paperwork to fill out, one page of which was "where do you want the money transferred" and I could have entered anything there and the money would have been sent to that account. Then I sent that stack of paperwork back in the mail, praying that no one along the way replaced that one sheet of paper with one with a different account number.
