The rule of “governor is the guardian of recusant” has an important role in resettlement of claims in Iranian law. This juridical rule is the basis of reconcile in legal relationship of people. By using this rule, the judges can compel those who refuse to fulfill the right of others to fulfill their right. The main subject of this thesis is the usage of this rule in people’s financial and non-financial affairs and in obligations. The research problem is the how and the why of governor intervention in people’s affairs. We will explain that how can governor be guardian’s representative to administer justice. It is clear that Iranian judges frequently cite to this rule to compel obligor to fulfill his/her obligation, and so the justice will establish. But there is no doubt that the governor intervention in people’s affairs is not an absolute intervention and the regular terms of law should be considered to establish this juridical rule on its appropriate position. In fact the governor intervention is restricted to the case that if he do not intervene it leads to chaos and disorder in society. In this case the governor cite to this juridical rule to compel the obligor to fulfill his/her obligation. It should be noted that although we have to accept the governor intervention, but this intervention leads in increasing the court cases because people will complain to court for little conflicts which impose lots of charges on themselves and society. The losing party also can exploit from this rule because he/she can hide his/her belongings during legal procedure.
