Membership in the credit union is voluntary and is open to all citizens bound by with joint work or residence, who wished to create a credit union to use its services and are willing to take on relevant commitments and responsibilities. Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. The supreme body of the World Council of Credit Unions is the Assembly, which elects the president and the board of directors of WOCCU. The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit. Unlike banks credit unions limit their activities to a closed circle of people. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union.
