National law, also known as domestic law, includes laws that exist within a particular nation or state. These laws can stem from decisions made by judges, which are referred to as case law, or they may be enacted by the nation’s legislature. In the United States, Congress enacts laws that are subsequently accepted by the president to become federal law. These laws are arranged by subject matter in the United States Code.

International law and national law are two concepts that prospective law professionals should understand before choosing their area of expertise. While entities use international law to form treaties and solidify agreements between different countries, national laws focuses on county and state laws that occur within a single country. International laws are created through conventions and treaties, while national laws are governed by the legislative, judiciary and executive entities in a single country.
