american law motrgage information
A rule of conduct or procedure established by custom, agreement, or authority. The body of rules and principles governing the affairs of a community and enforced by a political authority; a legal system: international law. The condition of social order and justice created by adherence to such a system: a breakdown of law and civilized behavior. A set of rules or principles dealing with a specific area of a legal system: tax law; criminal law. A piece of enacted legislation. What is Law?
