How does law differ from other types of social norms?

The rule of law differs from other social norms. There are certainly similarities between law and morality, but the differences between them are quite significant. First, the norms of law are fixed by the state, and, for example, moral norms by society. Secondly, legal norms are mandatory in nature, and the fulfillment of other social norms depends on the wishes of a particular person. Thirdly, legal norms are written, that is, they are enshrined in laws and other legal sources, while other social norms are not. There are many other differences as well.
