The article presents the possibilities of applying the provisions of the 1983 Code of Canon Law in the legal system of Ukraine. A historical outline of the shaping of the structures of the Latin Church from the achievement of independence by Ukraine in 1991 and their current state is presented. Then the canonical status of structures of the Latin Church in Ukraine was shown and the legal way of existence and creation of these structures in the Ukrainian legal order was analyzed. It was emphasized that the disadvantage in the legal system of Ukraine is the failure to recognize the legal personality of the Church resulting from its nature. It was suggested that signing the concordat with the Holy See would avoid unnecessary and dreadful wording in the statutes of religious organizations, so that they could enjoy the recognition of legal personality in Ukrainian legislation while maintaining their legal and canonical status.
