Family businesses are the largest global source of jobs in the private sector. This sector is an essential prerequisite for the full-fledged integration of any economy into the global economic space. For the Czech economy, the importance of foreign trade is increasing, and is dependent on the capabilities of companies to expand to foreign markets. The goal of this article is to identify whether family businesses operate solely on a regional basis or whether they are diversifying their export territory in relation to the involvement of the generation of successors, and to demonstrate a correlation between the structure of the industry and export destinations. A secondary goal is to discuss the demand mechanisms for SMEs oriented toward export. The scientific hypotheses defined are focused on demonstrating a dependency between the diversification of export territories and the involvement of the generation of successors in the management of the company. Ahe authors have demonstrated that family businesses managed by the first generation of founders export primarily to the territories of Slovakia, Germany, and the EU. Companies where the next generation contributes to management diversify territorial risk and also export outside the EU countries. A significant correlation was also demonstrated between the structure of the industry and the diversification of export. The uniqueness of this article lies in the topicality of the real transition of Czech family businesses to the next generation, which carries out foreign trade to promote the further development and sustainability of the family business for future generations.
