Activity of participation in football competitions by our football clubs is both amateur and professional. An attempt is made here to demonstrate the organization and activity of professional football clubs. The usual organizational form of this association today fi nds an alternative in the sport joint stock company. The advantages and disadvantages of the organizational types of football clubs are analyzed. Due to increasing commercialization of football, the issue of appropriateness of the organizational form in our most successful clubs is questioned. The economically unsound clubs must undergo the catharsis tic step of transforming into a sport joint stock company. The presumptions and the process of obligatory reshaping are in detail regulated by the provisions of the Sport Act. As voluntary transformation takes place under the same provisions, additional legal elaboration of the provisions on that type of transformation is suggested. Also suggested is the introduction of sport joint stock companies with limited liability. That corporation should not emerge by being founded but only by transformation of sport joint stock companies.
