Marriage and the family are important institutions of human society. As we know, they include different private institutions: the institute of kinship, the institute of motherhood and fatherhood, the institute of property, the institute of social protection of childhood and guardianship, and others. The process of family formation is the process of assimilation of social norms, roles and standards that regulate courtship, the choice of a marriage partner, family stabilization, sexual behavior, relations with the parents of spouses.The sociology of the family in a narrow sense, as part of general sociology, as a theory of the “middle level”; considers a special sphere of life and culture of families. The sociology of the family deals with a group, and not with an individual subject of life activity. A group of people connected by family and kinship relations forms that part of the social reality that is studied by the sociology of the family, where the family lifestyle is at the forefront. The sociology of the family considers the individual as a member of the family, integral part of the society. The sociology of the family correlates with the sociology of the individual; it studies personality, first of all, through the prism of socio-cultural intra-family ties, family identity of the individual. In any societythe family has a dual character. On the one hand, it is a social institution, on the other-a small group that has its own laws of functioning and development.
