How does civil-law procedure differ from common-law procedure?

The primary distinction between civil-law and common-law procedure lies in the roles assigned to the parties and the judge in shaping litigation.1

Key Procedural Differences

• Role of the Judge: In common-law systems, the judge acts as a neutral moderator or referee, deciding which party presents a more convincing case. In contrast, civil-law judges often function as investigators, actively questioning witnesses and parties to ensure a just outcome. In some civil-law jurisdictions, judges are required to guide proceedings by directing parties toward specific points of fact or law.12
• Responsibility for Evidence: Common-law procedure is adversarial; parties and their lawyers are responsible for gathering and presenting evidence. While civil-law systems also require parties to prepare their own cases, they rely more heavily on the judge to order the production of documents and witnesses as the case progresses.123
• Discovery: Common-law systems, particularly in the United States, utilize extensive pretrial discovery, allowing parties to compel the disclosure of information. Civil-law systems generally lack such broad discovery, as they rely on judicially guided investigation to uncover facts.3
• Judicial Background: Common-law judges are typically appointed mid-career from the practicing bar, whereas civil-law judges are part of a professional elite trained specifically for judicial service throughout their careers.1
