What Is International Law? A Plain-Language Answer
International law is the body of rules that governs how states, international organisations, and sometimes individuals behave across national borders. It decides things like how countries sign trade deals, what happens when one country invades another, and who gets refugee protection.
Think of it as the legal system that operates above the level of any single country. No single government enforces it. Instead, it works through treaties, international courts, diplomatic pressure, and shared norms that states have agreed to follow.
International law divides into two broad branches. They are related but serve different purposes.
Public International Law
This governs relations between states and international organisations. It includes the UN Charter, war laws (Geneva Conventions), human rights treaties, maritime boundaries, environmental agreements, and diplomatic immunity rules. The International Court of Justice (ICJ) in The Hague is the main judicial body here.
Private International Law
This is also called conflict of laws. It deals with which country's domestic law applies when a legal dispute crosses borders. For example, if an Indian company signs a contract with a German firm and a dispute arises | which country's courts handle it, and which law governs? Private international law answers those questions.
A third area that has grown significantly is international economic law. This covers WTO rules, bilateral investment treaties (BITs), free trade agreements, and foreign direct investment regulation. India's trade disputes at the WTO and its expanding BIT programme have made this area increasingly important for Indian lawyers.
Why Study International Law in India? The 2026 Case
India is no longer a passive player in global legal architecture. The country is now party to hundreds of bilateral treaties. It participates actively in WTO dispute settlement. It has pushed through a new Model Bilateral Investment Treaty. It hosts arbitration institutions like the Mumbai Centre for International Arbitration (MCIA) and Delhi International Arbitration Centre (DIAC).
Several forces are driving demand for international law expertise in India right now.
Trade law complexity is growing. India's FTA negotiations with the UK, the EU, and the GCC require lawyers who understand trade law, non-tariff barriers, and dispute settlement mechanisms. Government ministries and private exporters both need that expertise.
Cross-border investment is surging. Foreign direct investment into India hit record levels in recent years. Every large FDI transaction needs legal work at the intersection of Indian domestic law and international investment law. Law firms handling these deals need lawyers who understand both sides.
International arbitration is becoming India's future. India's government has stated an ambition to make the country a leading arbitration seat. New MCIA and DIAC rules, aligned with international standards, create demand for lawyers trained in international commercial arbitration | a field that mixes international law with contract and dispute resolution expertise.
Human rights law remains relevant. India's engagement with UN treaty bodies, UPR reviews, and human rights litigation before the Supreme Court all require lawyers with international human rights law knowledge. Civil society organisations, academic institutions, and government bodies all employ such lawyers.
How International Law Is Taught in India | LLB vs LLM
International law is not a standalone undergraduate degree in India. You encounter it in two main ways.
As Part of LLB
All BCI-approved LLB programmes | both 3-year and 5-year integrated | include international law as a compulsory subject. Usually it appears in the third or fourth year of the 5-year programme and in the second year of the 3-year course. The subject covers fundamentals of public international law: sources of law, subjects, treaties, state responsibility, and dispute settlement.
At top NLUs, the LLB international law course goes further. It covers landmark ICJ decisions, customary international law formation, human rights conventions, and international humanitarian law. Students participate in international moot court competitions | the Philip C. Jessup International Law Moot Court Competition is the most prestigious of these globally.
As an LLM Specialisation
This is where you go deep. LLM programmes in international law run for 1 to 2 years. They are available at NLUs through CLAT PG, at NLU Delhi through AILET, at JNU through their entrance test, and at private universities through LSAT-India or their own tests.
An LLM specialising in international law typically covers 8 to 12 core courses across four areas: public international law theory, international economic law, dispute resolution (arbitration, ICJ, WTO), and a specialisation track such as human rights, environmental law, or investment law.
International Law Syllabus | Topics You Will Actually Study
The topics below represent a consolidated view of what appears across major Indian LLM international law programmes. Individual university syllabi vary, but these are the core areas.
Top Colleges for International Law in India 2026
The quality of international law education varies significantly across institutions. Here is a realistic ranking based on faculty strength, curriculum depth, research output, moot court tradition, and placement outcomes.

JNU and SAU are the best choices for academic international law research with a social science lens. JGLS has the strongest international faculty presence. NLU Delhi combines strong theory with proximity to Delhi's legal institutions.
How to Get Admission | LLB and LLM International Law
The admission path depends on whether you want the LLB route or the LLM specialisation route.
LLB Route (Start After Class 12)
Clear Class 12 with 45% (40% for SC/ST)
No specific stream required. Science, Commerce, and Arts students all apply. The minimum percentage requirement is set by the Bar Council of India and individual universities.
Appear for CLAT or AILET
CLAT (conducted by the Consortium of NLUs) is the entry point for 24 NLUs including NLSIU, NALSAR, NUJS, and GNLU. AILET is the entry point for NLU Delhi. LSAT-India works for JGLS and some private universities. Prepare for at least 8–10 months. Read our CLAT preparation guide for a complete strategy.
Complete Your 5-Year BA LLB Programme
International law appears as a compulsory subject in your third or fourth year. Use this time to build foundations | attend seminars, participate in Jessup moots, and start reading basic international law texts like Shaw's International Law and Brownlie's Principles.
LLM Route (After LLB)
Eligibility: LLB with 50% (45% for SC/ST)
Any BCI-approved LLB or BA LLB degree qualifies. Final year students can apply provisionally. Some universities accept candidates with equivalent law degrees from foreign institutions, subject to eligibility verification.
Choose Your Entrance Exam
CLAT PG for most NLUs. AILET for NLU Delhi. JNU Entrance Test for JNU. SAU Entrance Test for South Asian University. LSAT-India for JGLS. Research the specific test and its syllabus well before applying. CLAT PG tests law subjects directly through MCQs unlike the UG paper.
Apply and Select International Law Specialisation
During LLM counselling, choose international law as your specialisation where that option exists. At NLU Delhi, international law is a formal LLM track. At NLSIU, it forms a key elective cluster within the LLM programme. At JNU and SAU, the entire programme focuses on international relations and international law.
Career Paths in International Law | What You Can Actually Do
International law offers careers across government, private practice, academia, and civil society. The paths are genuinely diverse | and the skills transfer across all of them.
Beyond these four paths, international law graduates also find roles in:
- Human rights organisations and international NGOs (Amnesty International, Human Rights Watch, ICRC India)
- Think tanks and policy research institutions (Gateway House, Carnegie India, Observer Research Foundation)
- Academic positions at law schools | teaching international law, jurisprudence, or specialised international courses
- Refugee law and immigration advisory at UNHCR India and civil society organisations supporting asylum seekers
- Environmental law practice, particularly climate litigation and international environmental compliance
- International commercial contracting at large Indian corporations with significant cross-border operations
Salary in International Law India | What to Expect at Each Stage
Salary in international law varies more than in most legal practice areas. The range from entry to senior level is wide. Location, employer type, and specialisation within international law all matter significantly.
| Experience Level | Role Examples | Salary Range (India) |
|---|---|---|
| Entry (0–2 years) | Junior associate at law firm, legal researcher at NGO or think tank, government officer | ₹5–8 LPA |
| Mid-level (3–6 years) | Associate at international arbitration team, government legal adviser, corporate counsel (cross-border) | ₹10–25 LPA |
| Senior (7–12 years) | Senior associate or partner track at top firm, arbitrator, MEA joint secretary (legal) | ₹25–60 LPA |
| Expert level (12+ years) | Lead arbitration counsel, partner at international practice, Senior Advocate with international clients | ₹50 LPA–₹1Cr+ |
| International Organisations | Legal officer, programme officer, treaty adviser at UN, WTO, ICRC | USD 50,000–120,000/year |
The fastest salary growth in international law currently comes from international arbitration practice. Arbitrators and counsel in ICSID or ICC proceedings command some of the highest legal fees in any practice area. Building expertise here typically takes 8–12 years but pays off significantly.
Skills You Build Studying International Law
International law trains skills that transfer broadly across legal careers. These are not just nice-to-have additions | they are what make international law graduates valuable beyond purely international roles.
Treaty Reading and Analysis
International lawyers learn to read dense, multilingual treaty texts and identify what each party agreed to | and what they did not. This skill transfers directly to commercial contract drafting and interpretation in domestic practice.
Comparative Legal Research
Understanding how different legal systems approach the same problem | common law versus civil law approaches to state immunity, for example | builds the kind of flexible legal thinking that makes lawyers effective across jurisdictions.
Oral and Written Advocacy Under Pressure
International moot courts like Jessup demand tightly argued oral submissions on complex legal issues in English, often against teams from leading global law schools. The preparation builds both writing and oral advocacy skills to a high standard.
Interdisciplinary Analysis
International law constantly intersects with political science, economics, and history. Climate law requires understanding of atmospheric science. Trade law requires economics. Investment law requires accounting knowledge. Students who study international law develop genuine comfort with interdisciplinary analysis | a skill employers across sectors value.
Multilateral Negotiation Simulation
Many international law programmes include Model UN-style exercises and treaty negotiation simulations. These develop skills in structured negotiation, coalition building, and diplomatic communication.
India's Role in International Law | Context Students Need to Know
India has a complex relationship with international law that shapes how it is taught and practiced domestically.
India is a dualist country. International treaties do not automatically become domestic law. Parliament must pass legislation to incorporate treaty obligations into Indian law. This means Indian lawyers must understand both the international obligation and the domestic implementing legislation.
India has been a significant player in shaping international law, particularly in areas like the New International Economic Order debate, the development of UNCLOS provisions, and its approach to human rights conventions. It has also been selective in accepting compulsory ICJ jurisdiction and has withdrawn from certain international monitoring mechanisms when national interest was perceived to be at stake.
For law students, this means understanding India's international law positions is as important as understanding the rules themselves. India's WTO dispute record, its approach to bilateral investment treaties post-2016 Model BIT, and its engagement with climate agreements all reflect deliberate legal and policy choices worth studying carefully.
How to Prepare for International Law If You Are a Student Right Now
You do not need to wait until your LLM to build meaningful international law knowledge. The students who enter the field most successfully start early.
Read the foundational texts early. Malcolm Shaw's International Law and J.G. Starke's Introduction to International Law are two texts that appear on almost every Indian LLB international law reading list. Reading either during your LLB years gives you a foundation that makes advanced study far easier later.
Follow international legal developments actively. The ICJ hands down judgments on territorial disputes and state responsibility. The WTO Appellate Body has ongoing trade disputes involving India. Follow these through legal news platforms and through the official websites of the ICJ (icj-cij.org) and WTO (wto.org). Both publish their full decisions publicly at no cost.
Participate in Jessup. If your law school fields a Jessup team, join it. If it does not, form one. The Jessup problem is released each year and deals with a complex public international law scenario. Preparing for it will teach you more about international law in four months than most classroom courses do in a year.
Seek international law internships. Internships at MEA, at law firms with international arbitration practices, at ICRC India, or at UNHCR India all signal commitment to the field. These are also where you build the networks that lead to jobs. Apply early | positions at international organisations require lead time.
Consider a foreign LLM. For top international law careers | particularly at UN bodies and global law firms | a foreign LLM from a recognised programme significantly strengthens your position. Programmes at institutions in the UK, Netherlands, and Switzerland are particularly strong for international law. Scholarships like Chevening (UK) and Fulbright-Nehru (US) are available to Indian lawyers. See our law scholarships guide for details.
Frequently Asked Questions
Public international law governs relations between states and international organisations. It covers treaties, the UN Charter, human rights, war laws, and the jurisdiction of bodies like the ICJ. Private international law | also called conflict of laws | applies when private parties (businesses or individuals) are in a legal dispute that crosses national borders. It decides which country's courts have jurisdiction and which country's law applies to the dispute. Both appear in Indian LLB curricula, though LLM programmes tend to specialise more heavily in public international law.
Yes, but with an important step in between. The 3-year LLB programme is open to graduates from any discipline with a minimum 45% in their undergraduate degree. After completing the 3-year LLB, you can then pursue an LLM specialising in international law. JNU also admits non-law graduates into its MA in International Studies, which includes significant international law content from a social science perspective. The JNU route is particularly suited to those who want an academic or policy career rather than a legal practice career.
Yes | with realistic expectations. International law is a strong career choice for students willing to invest in deep specialisation over a period of years. The field is not a fast money career at the start. Entry-level roles at NGOs, think tanks, or even law firms with international practice typically pay less than corporate transactional law roles. However, mid to senior level international arbitration practitioners, trade law advisers, and investment law specialists earn very competitive salaries. India's growing trade footprint, expanding BIT programme, and arbitration hub ambitions are all structural tailwinds that will increase demand for international law expertise through the decade.
For most NLUs: CLAT PG (Common Law Admission Test Postgraduate), conducted by the Consortium of NLUs. For NLU Delhi specifically: AILET (All India Law Entrance Test). For JNU: JNU Entrance Test (a separate institutional exam). For South Asian University: SAU's own entrance test. For private universities like Jindal Global Law School: LSAT-India or the university's own test. Most serious aspirants appear for CLAT PG as it opens the widest range of NLU options. The CLAT PG paper for 2026-27 follows a passage-based MCQ format covering core law subjects.
India has not accepted the compulsory jurisdiction of the International Court of Justice under Article 36(2) of the ICJ Statute without limitations. India has accepted jurisdiction only for specific disputes and subject to certain reservations. The ICJ can still hear cases involving India through ad hoc agreements between states, or where a treaty specifically confers ICJ jurisdiction. The Kulbhushan Jadhav case (India v. Pakistan) is a recent example where the ICJ exercised jurisdiction over a dispute involving India based on the Vienna Convention on Consular Relations.
The Philip C. Jessup International Law Moot Court Competition is the world's largest moot court event with participants from over 100 countries. Each year's problem involves a complex public international law scenario that teams argue before simulated ICJ proceedings. India has a strong Jessup tradition | NLU teams regularly reach international rounds in Washington D.C. Participation signals serious commitment to international law and provides deep practical preparation in legal research, treaty interpretation, and oral advocacy. If you want a career in international law, Jessup participation is among the single most valuable things you can do during your LLB or LLM years.
