Public vs. Private International Law

Public international law regulates relations between states and international organizations. In contrast, private international law regulates legal relations between individuals that involve a foreign element.

The Role of Legislation

Legislation is a critical source of private international law because it provides clear legal rules regarding:

• Nationality
• Jurisdiction
• Conflict of laws

Courts rely on these established rules to resolve international private disputes effectively.

Understanding Conflict of Laws

Conflict of laws arises when a legal case is connected to more than one country. In such instances, the court must determine which country’s law is applicable to the case.

Case Study: Marriage in the UAE

When a foreign national wishes to marry in the United Arab Emirates, a specific legal issue arises regarding the applicable law. The court must decide whether to apply the individual’s national law or the laws of the UAE to govern the marriage.
