Money is the main axis of banking. Money, which is one of the most important human inventions, has revolutionized the world economy and has met many of the world's economic needs. In order to regulate and coordinate the published money, a public reference is needed to meet the monetary needs of the society in the first place and the credit needs of the society in the next. This place or reference is the bank. Regardless of the history and origin of banks, it should be acknowledged that the relationship between natural and legal entities and banks, as well as the relationship between the market and banks, is a very complex relationship with many widespread and at the same time disturbing rules and regulations. Another problem is the existence of numerous banking and monetary activists. Today, in addition to state-owned banks, private banks, non-bank financial and credit institutions, exchange offices, leasing companies, credit and fund cooperatives, and Interest-free Bank are some of the monetary and banking activists. Banks also have many duties and powers. These duties and powers range from keeping people's money to granting facilities and guarantees and letters of credit and other issues. Each of the aforementioned stages and cases has its own relations and laws, the violation of any of which causes legal issues and problems, which are sometimes very serious. Eventually, legal institutions emerged to settle the disputes and to solve the issues. One of the most important people who play a role in the process of disputes is a lawyer.
