The ever-increasing competition forces companies to look for new outlets for their products. One way to break into new territories is to export. The authors chose the topic of exporting family businesses as a possible step in their future development. The aim was to compare the export activities of family companies according to their legal form. Another objective was to evaluate the effect of the exchange rate in the period before, during and after foreign exchange interventions on foreign activities. The contribution is based on general scientific methods, especially the method of compilation of specialized texts, primary quantitative and qualitative research, time series, deduction and generalization. The outputs are measured by classical statistical methods, Pearson's correlation coefficient, Crombach's alpha. The results of this study confirmed the assumption that even small and medium-sized Czech family businesses use export activities for their development. To a greater extent, companies export legal forms to joint stock companies and limited liability companies compared to self-employed.
