Generally the US law about evidences is really different from the accepted method in Iranian and French legal system. Thus in American courts both documentary and testimonial are accepted, but about superiority of one over the other, where rely on acts writing is necessary, written evidences are superior to testimonial, However, where there is not any superiority, the court reviews all the circumstances, so based on convincing evidence is determined. However, in France and Iran typically either in theory or in practice notarize act is superior to other evidences and the other ones cannot withstand versus notarize act.
