Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. 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). Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate. Worldwide credit union movement is represented by regional confederations and national organizations within the World Council of Credit Unions.
