Paper main body. Analyzed the issue of marriage and family relations in the process of formation and development in Ukraine. History of the Ukrainian family law reaches ancient times, even before the formation of Kievan Rus as a state, let alone the adoption of Christianity. In ancient times in our history the Ukrainian lands major factor regulating social relations advocated custom. Personal property and non-property rights of spouses dependent on the shape and conditions of marriage. Matrimonial law Kievan Rus was a kind and unique because formed based on Byzantine law, pagan rituals, various folk customs and princely legislation. To simplify and facilitate the marriage in 1897 was issued a collection of religious and civil laws on divorce and judicial proceedings in matrimonial matters, where it was said that people of Orthodox religion can marry among themselves and with foreigners Orthodox and all other Christian denominations not asking for special permission from the authorities, but with all the marriage requirements.

The adoption of Christianity created favorable conditions for the rapid development of social, economic, political and spiritual relations, preparing the ground for organizing the legal system, both in general and in the field of marriage and family relations. Christianity, including Orthodox Church, had a great influence on the formation of new ethical norms of life which, to some extent found their reflection in the new legal system. Further evolution took place right in the direction of humanization. Thus, the Christian church has become a stabilizing factor in the socio-political system and legal development as Kievan Rus and modern Ukraine.
