To get a loan in the credit union a shareholder must be not only a formally adopted there, but necessary pay in cash contributions, the amount and order of payment of which approved by the General Assembly and fixed by the charter. 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). Some credit unions are closed, serving only their members. However, the more and more popularitywin cooperatives of open type. Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America.
