Law today encompasses a vast amount of doctrine generated by constitutions, treaties, statutes, rules, court decisions, admininstrative regulations, and other legal sources. No lawyer knows all of the law! Yet lawyers receive a general license, enabling them to practice in any area, and many new lawyers practice in areas they have not previously studied. How is that possible? What type of knowledge is necessary to establish minimum competence to practice law?
Research shows that lawyers need three types of knowledge to practice competently: knowledge of the Rules of Professional Conduct, knowledge of legal processes and sources of law, and knowledge of threshold concepts in a wide variety of doctrinal fields. This knowledge, combined with the skills needed for minimum competence, allows lawyers to learn and practice in any area. See these pages to read more about each knowledge domain:
