Finding Foreign and Comparative Law


Foreign law consists of the nationals laws (as referred to as domestics laws) of individual foreign countries. Comparative law involves comparing foreign legal principles and institutions with another.

When beginning to research a foreign legal systems it is worthwhile considering a few issues:

1. What do you need?

Are you looking for a constitution, statutes, cases or general information?

2. Find out how the laws are published in the country you are researching.

Are the laws published as codes, compilations of statutes or reporters? A good source to use to discover this type of information is the Foreign Law Guide.

3. What sort of structure does the legal system have?

Is it a civil system based on codes or a common law system, or is it mixed? The World Legal Systems website is a quick way to determine this.

4. Be wary of translations.

Many countries publish their laws in the country's official language not in English, in fact, very few foreign laws, and even fewer cases, are translated into English. Translations should be used carefully, they may not be authoritative, or up-to-date, and the quality of translation may vary.

5. You can approach your research by two routes - by jurisdiction or by subject.

You may need to try both, sometimes it is good to start with a country by country approach as you gain a wider understanding of the legal system in question.  Alternatively, particular subject collections may group together laws from different countries on particular topic's e.g. International Encyclopaedia of Laws, has volumes for criminal law, family law, cyber laws, environmental law and intergovernmental organizations.
