Iran’s legal system is encountering numerous ambiguities and gaps due to evident and unavoidable weaknesses in the field of legislation and the existence of a dual structure of laws, which has caused inadequacies and challenges for the arbitration institution. As a result, the public desire to refer claims to arbitration has decreased. One of the most critical legal weaknesses in arbitration can be the failure to determine the independence and impartiality of the exclusive arbitrator, conflict in jurisdiction and arbitration, and the creation of an arbitration institution in the case of divorce in a faraway from the existing conditions. The current conditions of the philosophy of arbitration, the gaps about the law regarding the expert opinion issued by the arbitrator, and the legal ambiguity regarding the issuance of a provisional order and the fulfillment of the request, at the same time, many laws seem obsolete and old when it comes to arbitration. In addition to the legal system's weaknesses regarding the arbitration institution, the educational system does not work properly to improve the level of knowledge of the people and law students, especially lawyers and judges, and the judicial system deals with the content of any protest with many interventions. In this way, it has taken the strength of the arbitration institution and its votes. On the other hand, it has caused the accumulation of arbitration votes in the judicial system, while this possibility exists in most of the world's legal systems. A kind of judicial supervision of the arbitration award is foreseen in the form of the possibility of protesting the arbitration award. This is only limited attention to a part of the decision issued by the arbitrator. Also, on the other hand, courts, in many cases prevent the implementation of arbitration decisions for many reasons, and all these issues have caused the lack of development of arbitration.
