Law is a broad field that encompasses the system of rules set by a society to regulate behavior along with the enforcement of those rules. Law students study all of a society’s rules, but usually specialize their law practice upon graduation into a particular area like civil or criminal law.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.
