This study examined how corporate governance codes specific to private family firms encourage the bright side and restrict the dark side of family influence. Moreover, it investigated whether these codes foster agency or stewardship tendencies of the family’s involvement in the business. The results of this qualitative research study revealed that the eight analyzed codes are not consistent in their recommendations and focus on different aspects of family influence. Nevertheless, some common recommendations could be identified-for instance, the relevance of family governance mechanisms to avoid conflicts.
