There are a lot of different interests of a person related to his diverse needs, that arise in his life. It is possible to single out the separate groups of such interests, for example, in the field of labor relations, family relations, property relations and so on.
That's why, the norms of law regulating these interests are grouped according to the branches of law, and the branches are united into the system of law, also they are mutually coordinated, moreover, the branches are complementary.
Consequently, the question of the system of law is the question of the constituent elements of law, their interrelations among themselves and the way of organization in the process of development. In other words, to investigate the system of law means to reveal its structural organization, to indicate the principles of its structure and development.
The structure and development of law are predetermined by the system of social relations that are formed at the appropriate stage of the development of society.
The system of law, being an objective phenomenon, is not formed arbitrarily, but in connection with the situation of the system of concrete historical social relations, being the expression of the modern state, which would not refute itself due to internal contradictions.
