Protecting children's rights and interests, especially within families, is crucial globally. Effective laws and enforcement are needed to ensure their safety and prevent violence, both offline and online. Kazakhstan's efforts in this regard, including legal protection for motherhood and childhood, are important. All of the above allowed for formulating the general purpose of the study – a comprehensive systematic examination of the protection of the subjective rights and legitimate interests of the child in family legal relations and in surrounding society (using the example of the Republic of Kazakhstan). The results were obtained using the tools of theoretical and methodological research of publications devoted to the problems and issues of observance and protection of children's rights and freedoms at the national and global levels, methods of comparative legal and comparative political research, content analysis of official documents, etc. In the study, key issues regarding the protection of children's rights in Kazakhstan were identified, including violence, neglect, and juvenile delinquency. It highlighted the growing number of appeals for the protection of violated children's rights and emphasized the urgent need for improvement in the child protection system. Promising areas for development include enhancing social services, reducing violence in families and institutions, improving legal protection against sexual harassment, and promoting child-friendly activities in preschool education. The study is of both theoretical interest and practical importance for various stakeholders involved in child welfare and protection. The research has practical value and originality in posing individual questions; it is aimed at examining in-depth the most important problems of maternity, family, and childhood protection in modern Kazakhstan.
