The existing works, by emphasizing the differences between the power of attorney contract and the investment deposit account, have emphasized the uncertainty of the legal relationship that has occurred; The position that is in the order of erasing the problem statement; Because simply calling the legal relationship indefinite without prescribing a special framework and rules will not only solve the problem; On the one hand, it will cause many problems for the banking network, such as what is the form of the relationship between the depositor and the bank and what rules does it follow, and on the other hand, it will cause conflicting opinions in the judicial system; In this article, an attempt has been made to give a logical answer to the problems raised by this group on the legislator's position of the law on banking operations without usury, with the help of the descriptive-analytical method and by adhering to the opinions of the Imami jurists and the general rules of the civil law, and in this way, the legislative theory Based on the power of attorney, knowing the above relationship is proved.
