Yarghv was the exclusive mongol jurisdiction court to resolve claims and disputes in various fields and was formed in most areas of the mongol Empire, including the patriarch of Iran (654-750 AH). The court mostly took place for political and some economical and social crimes, in Mongol military camps. In this court, some methods similar to Islamic courts were used, such as testimony, forced confession by torture, and presentation of written documents; and criminals were judged based on Yassa.
As Yarghvchy people were at the top of this Court. Yarghvchys, who were mostly Mongolian princes and commanders, judged based on Mongolian laws which rooted in Yassa. Dominance on yassa was the condition of becoming Yarghvchy.
In this paper we notice this court, its manner and trial style, via study of Ilkhanid Texts; and by this means throw light on history of judicial system in Iran.
