Socialist law or Soviet law are terms used in comparative legal studies for the general type of legal system which has been used in socialist and formerly socialist states. It is based on the civil law system, with major modifications and additions from Marxist–Leninist ideology. There is controversy as to whether socialist law ever constituted a separate legal system or not. If so, prior to the end of the Cold War, socialist law would be ranked among the major legal systems of the world.
