Foreign and comparative law involves studying the laws of different countries to understand how they work. In some countries, laws are written down in statutes and codes, while in others, court decisions play a bigger role. When researching a foreign country's laws, it's important to start with a guide or bibliography to find the right sources. Constitutions are key documents to look for, along with secondary laws like regulations and administrative decisions. Comparative law helps us see how legal systems differ around the world.
