In this work, A special law regulating the arbitration process, and this law is the Jordanian Arbitration Law No. 31 of 2001 and amended by Law No. 16 of 2018. Because of the importance of the arbitrator’s role, I will address the responsibility that entails, and therefore the title of this scientific trip will be the arbitrator’s responsibility, and I will divide it into two sections, where the title of the first topic will be the scope of the arbitrator's responsibility. The second topic will be entitled cases of arbitrator responsibility. As a result, the purpose of this study is to clarify the path that must be taken by the person who suffers damage as a result of the arbitrator's breach of his obligation in the arbitration contract, as well as the responsibility that must be adhered to by the contract's parties if they suffer any damage and the path that the third party must take him if he is not considered a party to the contract. Furthermore, the purpose of this research is to demonstrate the sort of compensation that the aggrieved party is entitled to as a result of the arbitrator's breach of duty.
