In this paper, the concept of family business is defined as a system that represents three mutually overlapping systems; family, work and ownership. Although, according to research done by Poza (2010), most family businesses do not survive the transfer of ownership to new generations, it is important to understand the importance of family business to the global economy. It is shown the occurrence of conflicts in family businesses and how it affects business and family relationships. Also listed are the types of conflicts and ways to resolve them. It is important to identify conflicts, work on their solutions and avoid their frequent repetition. It was pointed out that conflicts can have positive effects if family members cooperate with each other, discuss disagreements and accept new ways of working. This leads to greater mutual trust, greater connection within the family and a better decision-making process. However, if the conflicts are driven by emotions and disagreements in family relationships, they can have severe consequences for the family and the company. As an example of such an event, the conflict in the Gucci family business was listed. The life course of a family and a family business through three generations is shown and how there was a breakdown in the family that later had an effect on the company's operations. It was pointed out that the key to the success of family businesses is daily communication and cooperation between family members, as well as joint management and the process of planning the future of the company.
