What are the main purposes of law in society?

Its main purpose is to regulate the behavior of all members of society, all subjects who enter into legal relations. People realized the importance of law as a regulator of social relations in ancient times. Without this regulator, life can turn into chaos and disorder. It is very important that the legal provisions are actually valid. This means that there must be guarantees that ensure the real operation of legal norms. Then the rights and obligations will not be an empty declaration, but will be really valid categories.
