List of national legal systems
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.

As a scholar in the Civil Law, there were not a lot of opportunities for a university position in the U.S. and Canada. While most of Europe and the rest of the world had legal systems based on Civil Law, only Quebec and Louisiana used the Civil Law. Civil Law is based on comprehensive, continuously updated legal codes that specify all matters that can be brought before a court. The rest of the U.S. and Canada used the Common Law, which was based on the English legal system of case law where the law is based on prior judicial decisions of the courts.
