The term "conflict of laws" is primarily used in the United States and Canada, though it has also come into use in the United Kingdom. Elsewhere, the term "private international law" is commonly used. Some scholars from countries that use "conflict of laws" consider the term "private international law" confusing because this body of law does not consist of laws that apply internationally, but rather is solely composed of domestic laws; the calculus only includes international law when the nation has treaty obligations (and even then, only to the extent that domestic law renders the treaty obligations enforcable). The term "private international law" comes from the private law/public law dichotomy in civil law systems. In this form of legal system, the term "private international law" does not imply an agreed upon international legal corpus, but rather refers to those portions of domestic private law that apply to international issues.
