A name serves as a word that identifies and distinguishes individuals from each other and is composed of two components, a first name (forename) and a surname. A person's first name alone could not determine a person's identity in society, therefore surnames are used for better identification. The primary principle in choosing a first name is the freedom to do so, but this freedom should not be considered unlimited and should be limited by taking into account the established principles and criteria of society and individual and social interests. However, a person's surname is the same as the father's family name, although both names can be changed under certain conditions. The laws and regulations regarding name corrections and changes provide for authorities that have not been discussed comprehensively, and the question of this research is what authorities have the authority to handle this matter. In this practical research, we will examine the competent authorities in this regard, both administrative and judicial, with a special approach to judicial precedent and the legislator's attitude in the peace court.
