Getting started: What is International Law and how can I get involved?

There are many different branches of international law. You can find out more about them by clicking on one of the options below. Fundamentally and historically, international law has been divided into two main types: Public International Law and Private International Law. However, a relatively new category – Transnational Law – has emerged and presents interesting opportunities for learning and for careers. Furthermore, it is highly recommended that students who wish to pursue an international law career should have some background in comparative law.  

What we know as international law today has its roots in 400-year-old writings and legal documents, but international law is in fact thousands of years old. Some concepts underpinning international law today (such as equality, fairness, reciprocity, keeping one’s promises) developed in ancient civilizations and communities. For those interested in exploring the historical development of international law in greater depth, the Peace Palace Library in The Hague, one of the world’s most comprehensive collections of international legal materials, offers an invaluable starting point. https://peacepalacelibrary.nl/research-guide/history-international-law 

Versatile, complex, comprehensive – International Law is all that and more. It governs issues that range from the profoundly geopolitical and global to the unexpectedly mundane and local. 

International law: 

  • Defines statehood and enables states to formalize their relationships through treaties and other legal instruments 
  • It also provides mechanisms – legal, diplomatic, and political – for addressing violations of those commitments. 

It also:  

  • Determines who owns a meteorite that falls to Earth 
  • Regulates who may explore the ocean floor or outer space, and under what conditions 
  • Governs sovereignty claims over the Arctic and other maritime zones 
  • Regulates weapons of war and dictates how civilians and combatants must be treated during armed conflict 
  • Protects international investors operating abroad
  • Safeguards intellectual property across borders 
  • Protects the environment and fundamental human rights 
  • And even facilitates unusual forms of diplomacy, such as China’s longstanding practice of lending giant pandas to foreign zoos. standing practice of lending giant pandas to foreign zoos.  

International law is therefore central not only to diplomacy and global politics, but also to business, technology, environmental protection, criminal law and everyday legal practice. Whether one becomes a transactional lawyer, an M&A attorney, a product liability or corporate lawyer, a criminal defense attorney, or a family lawyer, encounters with international or cross-border (transnational) legal issues are increasingly unavoidable. At the same time, many lawyers choose to make international law itself the focus of their professional careers. This guide, and CICL Currents more broadly, is intended for all lawyers.  

As international law expanded beyond its traditional focus on sovereign states, new and diverse opportunities have opened for lawyers. The rise of international organizations—such as the UN, WTO, EU, and AU—creates roles for lawyers in policy development, treaty negotiation, and advising institutions involved in global governance. These bodies rely heavily on legal expertise to craft norms, coordinate multilateral action, and interpret complex international obligations. 

The growing involvement of individuals, corporations, and NGOs in international law also broadens the field. Lawyers now represent multinational corporations and civil society groups in international debates, compliance processes, and regulatory negotiations. At the same time, because individuals and private entities increasingly possess rights and obligations under international law, lawyers have new opportunities in advocacy before international courts and tribunals, including human rights bodies and investment arbitration panels. 

Finally, international law has become more relevant in domestic forums. Lawyers frequently litigate cases in national courts that involve treaty interpretation, customary international law, transnational regulatory regimes, and the domestic enforcement of international judgments. 

Collectively, these developments create dynamic pathways for lawyers to work in international policymaking, global dispute resolution, corporate compliance, human rights advocacy, and cross‑border litigation—opportunities that were far more limited only a decade or two ago.

What it is and what it does

Public International Law traditionally governed legal relationships between sovereign states. Such sovereign states were the creators, the subjects, and the enforcers of international law.  

Over time, the scope of public international law has expanded significantly. Today, international organizations play a central role as key actors and subjects of international law. Organizations such as the United Nations, the World Trade Organization, and numerous regional bodies such as the European Union or the African Union bring states together, coordinate collective responses to global challenges, and serve as platforms for negotiation, norm creation, and treatymaking. 

Public international law also increasingly involves individuals, groups of individuals, corporations, and nongovernmental organizations. These non-state entities participate in the creation, interpretation, and enforcement of international legal norms. Multinational corporations such as Alphabet, Meta, ExxonMobil, and Visa, as well as civil society organizations such as Amnesty International and BRAC, regularly contribute to debates within international fora and influence the development of international law and policy. At the same time, individuals and corporations are no longer merely objects of international law—they are increasingly its subjects. Treaties, customary international law, and general principles of law grant individuals and private entities rights, impose obligations, and provide avenues for accountability.  

The sources of public international law include: 

  • International treaties 
  • Customary international law 
  • General principles of law recognized by nations 

Judicial decisions of international courts and tribunals, as well as writings of scholars, are generally not formal sources of international law, though they are highly influential. However, certain international courts—most notably the Court of Justice of the European Union—play a particularly significant role in shaping binding legal norms. Scholarly bodies such as the International Law Commission provide the much-needed context, precision and systematization of international law norms.  

If you are interested in how these different sources work together and often interact with each other, refer to International Law Commission’s Report on ‘Fragmentation of International Law’, 2006: https://legal.un.org/ilc/documentation/english/a_cn4_l682.pdf 

These are the main issues that public international law addresses, and the key areas of public international law:  

  • Statehood and self-determination of nations and peoples 
  • State sovereignty, territorial integrity 
  • Jurisdiction of states over entities and individuals, as well as over other states 
  • Jurisdiction of international courts, tribunals and other dispute resolution bodies 
  • Responsibility of states and other actors in international law for violations of international law obligations 
  • The status of international organizations, corporations and individuals in international law  
  • Relationship between international and national/domestic law – what happens if there is a conflict between them?  
  • Peaceful resolution of international disputes 
  • Use of force and collective security 
  • International humanitarian law (law of armed conflict)  
  • Diplomatic and consular relations 
  • International law of the sea 
  • International human rights law 
  • International immigration and asylum law 
  • International criminal law and accountability for grave crimes 
  • International environmental law 
  • International trade and economic law 
  • There are also other, less well defined and yet clearly emerging issues: 
  • Cyber law 
  • The law of outer space 
  • Global health law  
  • The role of domestic courts and domestic justice systems in international law

  1. Law School Coursework and Seminars 
    Foundational courses in public international law, human rights, international organizations, international courts and tribunals, and the law of armed conflict, provide students with an understanding of the global legal order and the mechanisms by which international norms are created and enforced. Advanced seminars develop skills in treaty interpretation, international legal reasoning, and critical engagement with global governance. Students learn to read primary sources—treaties, UN Security Council resolutions, and international tribunal decisions—with precision, and are able to formulate arguments grounded in international legal principles. 
  2. Research Centers and Institutes 
    Institutes dedicated to international law (such as Emory Law’s Center for International and Comparative Law) give students opportunities to explore global issues beyond standard coursework. Research assistantships, policy labs, and workshops with practitioners and scholars expose students to the practical dimensions of international lawmaking and enforcement. These settings allow students to participate in drafting reports, monitoring compliance, or analyzing emerging issues such as cyber governance, climate law, and international human rights litigation. 
  3. Study Abroad, International Fieldwork, and Exchange Programs 
    Experiential learning in international law is enriched by studying or working in another jurisdiction. Programs that place students in international courts, NGOs, or intergovernmental organizations offer an inside view of how global institutions operate. Semester exchanges or short-term field courses—such as visits to The Hague Academy of International Law (https://www.hagueacademy.nl/), Geneva Academy of International Humanitarian Law and Human Rights (https://geneva-academy.ch/), or regional human rights courts (https://www.echr.coe.int/https://www.oas.org/en/iachr/Default.asp) immerse students in the institutional, political, and cultural contexts that shape international legal practice. 
  4. Hague Academy of International Law (Summer Programme) One of the most prestigious programs in public and private international law, drawing students globally for advanced courses taught by leading scholars. (Also available through fellowships like Emory’s Bederman Fellowship.)

  5. ABA‑Approved Foreign Study Programs The American Bar Association maintains a long list of foreign summer and semester programs offered by U.S. law schools, many of which include coursework directly relevant to public and private international law. Offerings include study programs in: 
    • The Hague (Netherlands) 
    • Geneva, Brussels, London 
    • Florence, Paris, Madrid, Buenos Aires, and many more 
      These programs are open to students from any ABA‑approved law school. [americanbar.org] 
  6. Language and Interdisciplinary Training 
    Effective international legal practice requires linguistic proficiency and interdisciplinary grounding. Mastery of foreign languages enables direct engagement with treaties, diplomatic communications, and comparative state practice. Training in political science, economics, international relations, and history deepens understanding of the forces that shape international legal developments. Exposure to global literature and cultural studies can also help lawyers interpret legal norms within broader societal and historical frameworks. 

Career Pathways (for educational, training and career opportunities in Public International Law – See Opportunities) include roles in diplomacy, intergovernmental organizations, international courts and tribunals, global NGOs, multinational corporations, and government agencies engaged in foreign affairs or international litigation.

What it is and what it does

Private International Law—also known as conflict of laws—regulates cross-border legal disputes involving private parties, such as individuals and corporations. It addresses situations in which legal relationships span more than one jurisdiction and answers critical procedural and substantive questions, including: 

  • Which country’s courts have jurisdiction 
  • Which law applies to a dispute involving foreign elements 
  • Whether and how foreign judgments, arbitration awards, or settlements following mediation, should be recognized and enforced.  

Private international law is essential in areas such as international contracts, transnational torts, family law, crossborder commerce, and global mobility, but it does not regulate the substance of these laws. If you are interested in practicing international transactional law, international antitrust or simply international M&A law, international tort or product liability law, or international family law, you need to adopt a transnational approach – please refer to our guide on transnational law.

Unlike public international law, which focuses on relations among states and international institutions, private international law addresses disputes involving individuals, businesses, contracts, property, families, and transactions connected to more than one legal system. 

Career pathways can include:  

International Litigation and Dispute Resolution – cross-border litigation involving questions such as jurisdiction, choice of law, recognition and enforcement of foreign judgments, and international service of process. Practice at large international law firms, boutique litigation firms, or specialized dispute-resolution practices. Skills in civil procedure, international litigation strategy, and comparative legal analysis are particularly valuable. 

International Commercial Practice – advising multinational companies how contracts operate across jurisdictions, how disputes can be resolved, and which legal systems may apply. Career paths include transactional practice, international arbitration, compliance, and advising companies engaged in global trade and investment. 

International Arbitration and Alternative Dispute Resolution – one of the most prominent career pathways for students interested in private international law. Lawyers in this field represent parties in disputes before arbitral tribunals, work with arbitration institutions, or serve as arbitrators. Knowledge of arbitration rules, treaty frameworks, and comparative legal traditions is increasingly important in a global economy. 

Family Law and Cross-Border Private Matters 
Private international law also plays a significant role in family-related disputes, including international child custody, divorce involving multiple jurisdictions, adoption, and recognition of foreign family-status judgments. Lawyers in this area often work at the intersection of domestic family law and international legal cooperation. 

Government, Judicial, and International Organization Careers 
Government lawyers, judges’ clerks, and officials working in international organizations may encounter private international law issues involving treaties, international cooperation, and judicial assistance. Organizations such as the Hague Conference on Private International Law contribute to the development of international rules governing cross-border legal relationships. 

Academic and Comparative Law Careers 
Students interested in research and teaching may pursue careers in comparative law, private international law scholarship, and legal education. Because the field requires understanding multiple legal traditions, it is particularly suited to students interested in comparative legal systems and globalization.

What it is and what it does

In addition to the classical branches of international law (public and private international law), contemporary legal practice increasingly involves phenomena that do not fit neatly within traditional distinctions. This is where the term transnational law, popularized by Philip Jessup comes in.  

Transnational law is not a separate area of law. It does not have its own norms or enforcement mechanisms. And yet, lawyers regardless of their practice area will be well advised to be aware of it.  

What does it mean to engage with transnational law? Many of today’s most pressing legal challenges are fundamentally transnational in nature: global supply chain regulation, business transactions, corporate accountability for human rights abuses, climate change and environmental protection, cross-border data protection, and financial regulation. These issues require lawyers to navigate multiple legal systems simultaneously and to understand how international and domestic legal norms interact. Thus, transnational law – which also could be referred to as transnational approach to law, or transnational legal methodology – encompasses international treaties, customary norms, and general principles of international law, but also includes domestic laws with or without extraterritorial reach, private regulatory regimes, corporate governance standards, soft law instruments, and cross-border dispute resolution mechanisms. Further, it involves cross-border litigation, arbitration and other dispute resolution mechanisms. chain regulation, business transactions, corporate accountability for human rights abuses, climate change and environmental protection, crossborder data protection, and financial regulation. These issues require lawyers to navigate multiple legal systems simultaneously and to understand how international and domestic legal norms interact. Thus, transnational law encompasses international treaties, customary norms, and general principles of international law, but also includes domestic laws with or without extraterritorial reach, private regulatory regimes, corporate governance standards, softlaw instruments, and crossborder dispute resolution mechanisms. This is where comparative law, in addition to international law, is an invaluable tool.  

For law students, engaging with transnational law opens pathways into careers in international business, arbitration, compliance, regulatory practice, environmental and human rights advocacy, and global governance. It also equips future lawyers regardless of practice area with the skills necessary to operate in an interconnected legal world.

  1. Reimann, J. Hathaway, T. Dickinson, J. Samuels,Transnational Law: Cases and Materials,West, 2013,  

‘The book’s goal is to orient students in transactions and disputes reaching beyond national boundaries. It offers them the basic knowledge and understanding of transnational law that every lawyer should possess today, and it lays the foundations upon which more specialized courses can build. The book is divided into five categories: the respective Actors, the nature of their Interaction, the major forms and effects of transnational Law, transnational mechanisms of Dispute Resolution, and the Domestic Effects of international rules. It approaches the material from an evolutionary perspective and shows how the landscape with regard to each of the five topics has changed, especially over the last half-century.’

Transnational law training occurs across multiple stages of legal education and professional development: 

Law School Coursework and Seminars 
Comparative and transnational law and regulation courses introduce students to multiple legal traditions while sharpening close-reading and synthesis skills. Seminars foster original research, cross-jurisdictional argumentation, and scholarly writing. 

Research Centers and Institutes 
Centers like CICL provide opportunities for students to engage with transnational law beyond the classroom. These include research assistantships, workshops with international scholars, and collaborative projects addressing global legal challenges. Such environments simulate professional research settings and expose students to comparative methodology in action. 

Study Abroad and Exchange Programs 
Immersion in another legal system—whether through semester exchanges, summer programs, or short-term field courses—deepens comparative insight. Learning law in its institutional and cultural context builds practical understanding that cannot be replicated through texts alone. 

Language and Interdisciplinary Training 
Transnational approaches benefit from linguistic competence and interdisciplinary literacy. Training in foreign languages, history, economics, or political science enhances a lawyer’s ability to interpret legal materials accurately and persuasively across jurisdictions. Reading classical literature from other parts of the world can help a lawyer to gain insights into the nation’s history and culture.

What it is and what it does

Comparative law is not simply about learning “foreign law.” Rather, it is a method of legal analysis, a set of professional skills, and a gateway to careers that increasingly demand legal fluency across borders, systems, and cultures. It provides lawyers and legal scholars with the tools that are necessary in today’s interconnected legal world. It is indispensable as a course of study for students willing to engage with international or transnational law.  

Comparative law offers a powerful framework for understanding how law functions in a globalized world—and how lawyers can operate effectively within it.

At its core, comparative law examines how different legal systems address similar problems: regulating markets, protecting rights, resolving disputes, providing redress, or responding to social change. These comparisons may involve civil law and common law traditions, religious or customary legal systems, or hybrid and transnational regimes. 

Comparative law trains lawyers to ask deeper, systemic questions: 

  • Why do legal rules take the form they do? 
  • How do history, culture, politics, and institutions shape legal outcomes? 
  • What assumptions are embedded in one’s “home” legal system—and what alternatives exist? 

This approach cultivates intellectual humility, analytical precision, and adaptability. Comparative lawyers learn to move beyond ‘what is familiar’ toward ‘what works’, contextual analysis, and critical evaluation of legal transplants and reforms. 

Why Comparative Law Matters Now: 

Global challenges—climate change, migration, technological regulation, public health—do not respect jurisdictional boundaries. Lawyers confronting these issues must understand how different legal systems respond and how solutions travel across borders. 

Comparative law equips lawyers not only to observe these dynamics, but to participate in shaping them. It transforms legal education into professional formation, emphasizing skills, judgment, and perspective that endure across careers and borders. 

For readers of CICL Currents, comparative law is more than an academic subject. It is a way of thinking about law’s possibilities—and a pathway to meaningful, globally engaged legal careers. 

Comparative law training occurs across multiple stages of legal education and professional development: 

Law School Coursework and Seminars 
Comparative constitutional law, comparative private law, and transnational regulatory courses introduce students to multiple legal traditions while sharpening close-reading and synthesis skills. Seminars can foster original research, cross-jurisdictional argumentation, and scholarly writing. 

Research Centers and Institutes 
Centers like CICL provide structured opportunities for students to engage with comparative law beyond the classroom. These include research assistantships, workshops with international scholars, and collaborative projects addressing global legal challenges. Such environments simulate professional research settings and expose students to comparative methodology in action. 

Study Abroad and Exchange Programs 
Immersion in another legal system—whether through semester exchanges, summer programs, or short-term field courses—deepens comparative insight. Learning law in its institutional and cultural context builds practical understanding that cannot be replicated through texts alone. 

Language and Interdisciplinary Training 
Comparative law rewards linguistic competence and interdisciplinary literacy. Training in foreign languages, history, economics, or political science enhances a lawyer’s ability to interpret legal materials accurately and persuasively across jurisdictions. 

Comparative law does not point to a single career track. Instead, it opens multiple professional pathways: 

Academia and Research 
Comparative law is foundational for careers in legal academia, think tanks, and research institutions. Scholars trained in comparative methods contribute to debates on legal reform, constitutional design, and transnational governance. 

International and Transnational Practice 
Law firms with cross-border practices value lawyers who can navigate multiple legal systems, coordinate with foreign counsel, and advise clients operating internationally. Comparative insight enhances effectiveness in arbitration, compliance, and transactional work. 

International Organizations and NGOs 
Organizations engaged in development, human rights, trade, and rule-of-law promotion rely heavily on comparative legal analysis. Lawyers in these roles assess legal frameworks, draft model laws, and advise on institutional reform. 

Government and Policy Roles 
Comparative law expertise supports careers in diplomacy, international economic policy, national security, and legislative drafting. Governments increasingly draw on comparative analysis to inform domestic lawmaking and regulatory design. 

Judicial and Clerking Opportunities 
Comparative reasoning appears with growing frequency in constitutional and supreme court jurisprudence worldwide. Clerks and judicial advisors with comparative training contribute to this dialogue and shape the evolution of legal doctrine.
