Liechtenstein

• The Constitution of 1921, as revised, the highest law, with a Prince and a parliament
• The Austrian Civil Code (ABGB), which has applied since 1812, and Austrian procedure
• The Persons and Companies Act, adapted from Swiss law
• Law of the European Economic Area, for matters covered by that agreement

• The Constitutional Court (Staatsgerichtshof)
• The Supreme Court, and the Court of Appeal
• The Princely Court of Justice (Landgericht), the court of first instance, and an Administrative Court

A law degree from Austria, Switzerland or elsewhere, practical training, and a licence from the government.

• A very old Austrian civil code is still in force in a different country.
• Its 1926 company law created the trust enterprise (Treuunternehmen), an adaptation of the Anglo-American trust to a civil-law country.
• Questions about the European Economic Area go to the EFTA Court, not to the European Court of Justice.

The University of Ottawa’s JuriGlobe database lists Liechtenstein as: Civil law. It names the systems in order of importance.

The map colours a country by the first-named system, and shows both civil-law and common-law countries as “mixed”. It is a simplification, and real systems are rarely pure.

Albania, Algeria, Angola, Argentina, Armenia, Austria, Azerbaijan, Belarus, Belgium, Benin, Bolivia, Bosnia and Herzegovina, Brazil, Bulgaria.
