Foreign law is the domestic law of any country that isn't the United States. Depending on the country's legal system, foreign law may include constitutions, laws, cases, customary law, regulations, executive declarations, and more. Availability of translated materials varies, and research may necessitate navigating a patchwork of free and subscription databases.
The best way to start your foreign legal research is to find the right research guide. This guide highlights the best places to look for country-specific and subject-specific research guides. It also contains tips for finding articles on foreign law—if someone else has already done the hard work researching another country's laws, you can use their findings as a shortcut. Last, this guide provides advice on citing to foreign law, which can be especially tricky due to gaps in the Bluebook's coverage.
