Conflict of Laws: Jurisdiction and Governing Law Explained

Updated 11 October 2026 · Fact-checked

Conflict of laws decides three things in a cross-border dispute: which country's court can hear it (jurisdiction), which country's law applies (governing law), and whether the result can be enforced abroad. Parties usually fix the first two by contract clause. Arbitral awards are enforced under the New York Convention.

Understand Conflict of Laws: Jurisdiction and Governing Law

A cross-border dispute raises questions that a purely domestic dispute does not. Two parties in different countries sign a contract. One breaks it. Which court hears the case? Which country's rules decide who is right? And if you win, how do you collect from a party whose assets are elsewhere? Conflict of laws, also called private international law, answers these questions.

Keep two ideas apart. Jurisdiction is about the forum: which court, or which tribunal, has the power to hear the dispute. Governing law (also called the proper law or applicable law) is about the rules: which country's law decides the rights and duties of the parties. They can differ. A contract can say that the courts of country A hear disputes, but that the law of country B applies. The court in A then applies B's law as a matter of evidence and argument.

The starting point in most legal systems is party autonomy. Commercial parties are free to choose both the court and the law, normally in a clause in the contract. Courts generally respect the choice. Limits exist: a chosen law will not be applied if it is contrary to the public policy of the forum, and some mandatory local rules, such as consumer protection or competition rules, apply whatever the parties chose. If the parties made no choice, the court decides using connecting factors, such as where the contract was made, where it is performed, where the defendant is based and which country has the closest connection to the deal.

A judgment is only useful if it can be enforced. A court judgment has no automatic force outside the country that gave it. The winner must usually ask a court in the country where the assets are to recognise and enforce it. This depends on local law, treaties or reciprocal arrangements, and it can be slow and uncertain. Courts commonly refuse where the original court lacked proper jurisdiction, where the defendant had no fair chance to be heard, where there was fraud, or where enforcement offends public policy.

This is a major reason businesses choose arbitration for international contracts. The New York Convention 1958 (the Convention on the Recognition and Enforcement of Foreign Arbitral Awards) requires the courts of contracting states to recognise and enforce arbitral awards made in other contracting states. Grounds for refusal are narrow and listed, for example an invalid arbitration agreement, a party not given proper notice or a chance to present its case, an award outside the scope of the submission, or an award contrary to public policy. The court does not re-examine the merits of the dispute. Because many countries are parties, an award usually travels further than a court judgment.

Key formulas to remember

Jurisdiction: Jurisdiction = which court or tribunal hears the dispute; Question words: where, which court, forum. Usually set by a jurisdiction clause or an arbitration clause.
Governing law: Governing law = which country's rules decide the dispute; Question words: which law, proper law, applicable law. Set by a choice of law clause.
Party autonomy: Chosen court + chosen law are normally respected, unless public policy or mandatory rules override them; State the exception whenever you state the rule.
No choice made: No clause → court applies the law with the closest connection (place of contracting, performance, parties' location); Exact test varies by country. Describe it in general terms.
Foreign judgment: Judgment has no automatic effect abroad → must be recognised and enforced by a court where the assets are; Depends on local law and any treaty or reciprocity. Refusal grounds include lack of jurisdiction, unfair process, fraud and public policy.
Arbitral award: New York Convention 1958: contracting states recognise and enforce awards made in other contracting states, refusing only on limited listed grounds; The court does not review the merits of the award.

How to solve Conflict of Laws: Jurisdiction and Governing Law questions

Use this order for any scenario question on cross-border disputes. It stops you mixing up the three separate issues.

1Identify the dispute and the countries involved: where each party is based, where the contract is performed and where the assets are.
2Read the contract for clauses. Look for a jurisdiction clause, a choice of law clause and an arbitration clause. Note that they are different things.
3Answer jurisdiction first: does a clause name a court or arbitral tribunal? If yes, it is normally respected. If no clause exists, the court uses its own rules and connecting factors.
4Answer governing law second: does a clause choose a law? If yes, apply it, subject to public policy and mandatory rules. If not, the court applies the law with the closest connection.
5Check for limits: is there a consumer, competition or other mandatory rule, or a public policy objection, that could override the choice?
6Turn to enforcement: is the result a court judgment or an arbitral award? A judgment needs recognition in the country of the assets and depends on local law or treaty. An award falls under the New York Convention if both countries are contracting states.
7State the conclusion in plain terms and link it to the facts, naming the likely refusal grounds if enforcement is at risk.

Quickest way: Three-question check: Who hears it? Whose law? Can it be enforced?

When to use it: Use this for Section A questions and for the first read of a Section B scenario, when you have about a minute per question.

Underline the clause wording. 'Courts of X' or 'tribunal in X' = jurisdiction or seat. 'Governed by the law of X' = governing law.
If the question says arbitration award and both countries are New York Convention states, the answer is almost always enforceable, unless a narrow listed ground applies.
If the question says foreign court judgment, expect enforcement to depend on the local law of the country where the assets are.
Eliminate options that say the court must ignore a valid choice, or that say a judgment is automatically valid in every country.

Common mistakes in Conflict of Laws: Jurisdiction and Governing Law

Treating jurisdiction and governing law as the same thing.
Both are often named by country, and both appear in the same boilerplate clauses.
Fix: Ask two separate questions: which court, and which law. Write them as two separate points in your answer.
Saying a foreign judgment is automatically enforceable in any country.
Students assume a court order carries authority everywhere.
Fix: State that a judgment must be recognised by a court in the country where enforcement is sought, under local law or a treaty.
Claiming the New York Convention applies to court judgments.
The word 'enforcement' appears in both contexts.
Fix: Link the Convention only to arbitral awards. Court judgments are covered by other treaties or local rules.
Saying a court re-hears the case when asked to enforce an arbitral award.
Students confuse enforcement with appeal.
Fix: Say the court checks only the limited grounds for refusal and does not review the merits.
Saying the parties' choice of law or court is always binding.
Party autonomy is taught as the main rule and the exceptions are forgotten.
Fix: Say it is normally respected, subject to public policy and mandatory rules of the forum.
Applying the forum's own law automatically because the case is heard there.
Students assume a court always uses its home law.
Fix: A court can apply a foreign governing law if the contract chooses it or the closest connection points there.

Worked examples

Example 1

Alpha Ltd (country P) sells machinery to Beta Inc (country Q). The contract says: 'Disputes shall be heard by the courts of country R. This contract is governed by the law of country S.' Beta fails to pay. Where can Alpha sue, and which law decides the dispute?

Show the solution

Identify the clauses: the first sentence is a jurisdiction clause. The second is a choice of law clause.
Jurisdiction: the parties chose the courts of country R. Courts normally respect this, so Alpha should sue in R.
Governing law: the parties chose the law of country S. The court in R will normally apply S law to decide the dispute.
Check limits: unless public policy or a mandatory rule objects, the choices stand. Nothing in the facts suggests either.
Note the point: the court and the law are from different countries. This is allowed and is not an error.

Answer: Alpha should sue in the courts of country R, and those courts will normally apply the law of country S, subject only to public policy and mandatory rules.

Example 2

Gamma Co wins an arbitral award against Delta Co. The arbitration was seated in country X. Delta's assets are in country Y. Both X and Y are contracting states to the New York Convention. Delta argues that the arbitrator misread the contract and asks the Y court to refuse enforcement. Advise Gamma.

Show the solution

Identify the issue: enforcement of a foreign arbitral award, so the New York Convention applies because both countries are contracting states.
State the rule: the Y court must recognise and enforce the award and may refuse only on the limited listed grounds.
Test Delta's argument: an arbitrator misreading the contract is an error on the merits. It is not a listed ground for refusal.
Mention grounds that would count: invalid arbitration agreement, no proper notice or chance to present the case, award beyond the scope of the submission, or conflict with public policy. None is alleged here.
Conclude: the court does not re-examine the merits.

Answer: Gamma should succeed. The Y court must enforce the award under the New York Convention, because a claimed error on the merits is not a ground for refusal.

Exam tips

Mark each clause in a scenario as jurisdiction, governing law or arbitration. Most wrong answers come from mixing them up.
Learn the exact link: New York Convention equals arbitral awards. Reject any option that applies it to court judgments.
In all-or-nothing questions, beware of absolute words like 'always', 'automatically' and 'must'. The correct answer usually contains a qualifier such as 'normally' or 'subject to public policy'.
In Section B scenarios, read the clauses first, then the facts. The five questions usually test the three issues: forum, law and enforcement.
Know the reasons businesses prefer arbitration across borders: neutral forum, privacy, expertise and easier enforcement of awards.

Conflict of Laws: Jurisdiction and Governing Law: frequently asked questions

What is the difference between jurisdiction and governing law?

Jurisdiction decides which court or tribunal hears the dispute. Governing law decides which country's rules are used to decide who is right. A contract can choose a court in one country and the law of another.

How are foreign judgments enforced internationally?

A foreign judgment has no automatic force. The winner must apply to a court in the country where the assets are. That court decides under its own law or any treaty. It may refuse for reasons such as lack of jurisdiction, unfair process, fraud or public policy.

What does the New York Convention do?

It requires courts in contracting states to recognise and enforce arbitral awards made in other contracting states. Refusal is allowed only on limited listed grounds, such as an invalid arbitration agreement or breach of public policy. The court does not review the merits.

What happens if the contract has no choice of law clause?

The court decides which law applies using connecting factors, such as where the contract was made and performed and where the parties are based. In general terms it applies the law with the closest connection to the contract.
