International private law, also called private international law, examines private legal relationships with cross-border elements. Jurisdiction, applicable law and the treatment of foreign judgments provide different questions when people, transactions or disputes involve more than one legal system.
Cross-border relationships and governing rules
Contracts, torts and family matters can involve foreign elements. Identifying that connection is a starting point for deciding which legal questions arise.
Cross-border business and individual relationships may require a framework for resolving competing legal claims. The rules and institutions involved depend on the jurisdiction and subject.
Jurisdiction concerns which forum may decide a matter; choice of law concerns which law applies. Recognition and enforcement of a foreign judgment raises another set of questions. Arbitration and other dispute-resolution processes also require attention to their particular rules.
Contracts, disputes and comparison
Simulations of contract drafting, negotiation, arbitration or mediation can help compare legal issues and possible approaches. They are educational exercises, not legal advice or confirmation of competence to handle a live case. The Public International Law guide provides a related comparison of legal questions and institutions while keeping public and private international law distinct.
Trade, investment arbitration, human rights, refugee law, cyber law and transnational litigation may raise related cross-border questions, but they are not all interchangeable with private international law.
Research and professional boundaries
Legal research can examine transnational issues and compare authorities, including differences in how sources are interpreted.
Continuing education and certification are separate arrangements from academic study of a subject.
Legal consultancy, litigation and teaching are possible professional contexts, with their own qualification and appointment requirements. Studying cross-border legal principles does not automatically admit a person to legal practice.
Questions about international private law
Are jurisdiction and choice of law the same question?
No. One concerns the forum; the other concerns the applicable law.
Is private international law identical to every form of international law?
No. Public international law and other cross-border fields have distinct subjects and institutions, although issues may overlap.

The HCCH overview of private international law distinguishes cross-border questions about jurisdiction, applicable law, recognition and cooperation. It offers external institutional context for academic comparison, rather than advice about a particular dispute.
