In Australia an employee would not commit fraud and risk losing his job or face imprisonment so I expect a trade receipt to be genuine.What do you mean by trade receipts? How do you verify that they are genuine. Fake LP report can be generated easily since there are no proper and known verification procedures.
But if someone is concerned, it wouldn't be hard to check the authenticity by contacting the LP.
Anyway, most people don't need to know who takes the other side of their trades so they don't have to worry about this.
