What Law Governs Your Contract When Your Client and Company Are in Different Countries?

You are a founder based in Dubai. Your company is registered in Estonia. Your client is a business in the United Kingdom. You sign a service agreement, the work goes well for six months, and then a dispute arises. The client refuses to pay the final invoice. You want to take action.

Which country's courts do you go to? Which country's law decides whether you win or lose? Who gets to choose?

This is one of the most practically important legal questions for internationally mobile entrepreneurs, and it is one that most people never think about until something goes wrong. By then, figuring out the answer is expensive and stressful. Understanding it in advance costs you nothing.

The Short Answer: It Depends on Your Contract

The first thing to understand is that, in most commercial relationships between businesses, the parties have significant freedom to choose which country's law governs their contract. This is known as party autonomy, one of the foundational principles of international contract law.

If your contract contains a well-drafted governing law clause (also called a choice of law clause), that clause will generally be respected and enforced by courts in most jurisdictions. The law you choose in your contract is, in most cases, the law that applies.

If your contract has no governing law clause, or if it has one that is ambiguous or unenforceable, then courts and arbitrators have to work out which law applies using conflict of laws rules. This process is slower, more uncertain, and more expensive than simply having specified it in the first place.

What Is a Governing Law Clause?

A governing law clause is a sentence, sometimes just one line, in your contract that specifies which country's legal system will be used to interpret and enforce the agreement.

A typical clause looks like this:

"This agreement shall be governed by and construed in accordance with the laws of England and Wales."

Or:

"This agreement is governed by the laws of the Republic of Singapore, without regard to its conflict of law provisions."

That clause does not mean disputes must be resolved in English or Singaporean courts; that is a separate clause called a jurisdiction clause or dispute resolution clause. But the governing law clause tells you which country's rules about contracts, breach, damages, and remedies apply when interpreting the agreement.

The two clauses are closely related and should be drafted together. A contract that specifies English governing law but requires disputes to be resolved in Nigerian courts creates unnecessary complexity. The most coherent approach is to have your governing law and your dispute resolution forum in the same place.

Why It Matters More Than You Think

Different countries have materially different contract laws. What counts as a valid contract, what remedies are available for breach, how damages are calculated, and what clauses are unenforceable all vary between jurisdictions.

Consider a few examples:

Limitation of liability clauses. In England and Wales, a clause limiting your liability to a fixed sum is generally enforceable between commercial parties, subject to a reasonableness test under the Unfair Contract Terms Act. In Germany, certain liability limitations are void under BGB provisions. In Australia, consumer protection law limits what you can contract out of. The same clause in your contract can be enforceable under one legal system and void under another.

Late payment. Under English law, there is a statutory right to claim interest on late commercial invoices under the Late Payment of Commercial Debts Act 1998. No equivalent right exists in many other jurisdictions. If your contract is governed by English law and your client pays late, you can claim interest automatically. If it is governed by the law of a country without such a statute, you may only be entitled to what the contract explicitly says.

Force majeure. English law does not have a general doctrine of force majeure; it has to be written into the contract. French law does. If your contract is silent and governed by English law, a pandemic or supply chain disruption that makes performance impossible may not excuse your obligations. Under French law, there may be a statutory route to relief.

Non-compete clauses. Enforcement of non-compete restrictions varies wildly by jurisdiction. California law makes most non-competes unenforceable as a matter of public policy. English law enforces reasonable ones. German law has its own specific requirements, including compensation for the restricted period.

The governing law you choose can determine whether specific clauses in your contract actually protect you.

What Happens If There Is No Governing Law Clause?

If your contract is silent on governing law, the applicable law is determined by conflict of laws rules, a body of private international law that each jurisdiction has its own version of.

In the European Union (and the UK, which retained the EU rules post-Brexit), the main instrument is the Rome I Regulation (Regulation (EC) No 593/2008), which governs the law applicable to contractual obligations. Under Rome I, the general rule is that a contract is governed by the law of the country where the party required to effect the characteristic performance of the contract is habitually resident.

For a service contract, the characteristic performance is the provision of the service, meaning the law of the country where the service provider is based. If your company is in Estonia and you are providing services to a UK client, the default under Rome I analysis would likely point to Estonian law.

But this is a starting point, not an absolute rule. Rome I has exceptions for closer connections, specific contract types, and consumer contracts. The analysis can become complex quickly.

Outside the EU/UK context, for example, if a dispute ends up in a US court, a UAE court, or a Singaporean court, each jurisdiction has its own conflict of laws framework, and the outcome may differ.

The practical consequence of having no governing law clause is that neither party knows in advance which law applies. Lawyers on both sides will argue for whichever system favours their client. The uncertainty adds cost and time.

Jurisdiction vs Governing Law: Two Different Things

These terms are often confused, and the confusion creates real problems.

Governing law (choice of law): Which country's legal rules apply to interpret the contract

Jurisdiction (choice of forum): which country's courts (or which arbitral tribunal) has the authority to hear and decide a dispute.

You can have English governing law with Singapore as the jurisdiction for disputes. You can have New York law governing a contract with arbitration seated in London. These combinations are legitimate and sometimes strategically sensible.

However, having them in different jurisdictions means the court hearing the case will be applying foreign law, which is possible but slower and more expensive than applying its own law. For most small and mid-size founder businesses, keeping governing law and forum in the same jurisdiction is simpler and cheaper.

Arbitration vs Litigation: The Choice That Matters for Cross-Border Enforcement

Even if you win in court, you have to enforce the judgment. Court judgments are not automatically enforceable across borders. A UK court judgment cannot simply be sent to a UAE enforcement authority and automatically collected. Bilateral and multilateral recognition treaties determine where court judgments are enforceable, and there are significant gaps.

Arbitration awards are different. The New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards (1958) has 172 signatory countries. An arbitration award from an institution like the ICC, LCIA, SIAC, or DIFC-LCIA can be enforced in any of those 172 countries through a relatively standardised process.

For international B2B contracts, particularly where the other party is based in a jurisdiction where enforcing a foreign court judgment would be difficult, arbitration as the dispute resolution mechanism is often the more practical choice.

A typical arbitration clause looks like this:

"Any dispute arising out of or in connection with this agreement, including any question regarding its existence, validity or termination, shall be referred to and finally resolved by arbitration under the LCIA Rules, which Rules are deemed to be incorporated by reference into this clause. The number of arbitrators shall be one. The seat of arbitration shall be London. The language to be used in the arbitral proceedings shall be English. The governing law of the contract shall be the substantive law of England and Wales."

The seat of arbitration determines the procedural law of the arbitration. London, Singapore, and Dubai (DIFC) are among the most commonly chosen seats for international commercial arbitration.

Which Governing Law Should You Choose?

There is no right answer, but there are practical considerations that narrow the field considerably for most internationally mobile founders.

English law is the most commonly chosen governing law in international commercial contracts globally by a significant margin. The reasons are practical: English contract law is sophisticated, extensively developed through case law, commercially sensible, and predictable. English courts have deep experience with international commercial disputes. English law is also widely understood by lawyers in most major jurisdictions, which reduces the cost of advice.

If your clients are in the UK or Europe, English law is often a natural choice. Post-Brexit, English law remains just as commercially relevant; the governing law rules did not fundamentally change.

Singapore law is the preferred choice for Asia-Pacific contracts. Singapore's legal system is based on English common law, and the Singapore International Commercial Court (SICC). The Singapore International Arbitration Centre (SIAC) are well-regarded globally.

New York law is common for US-facing contracts, particularly in tech, finance, and media. New York has a well-developed commercial law, and its courts are experienced with sophisticated international disputes.

UAE law / DIFC law is worth considering if both parties are UAE-based and have significant operations in the Middle East. The Dubai International Financial Centre (DIFC) has its own legal system based on English common law, and the DIFC Courts are increasingly respected for international commercial disputes.

The law of a neutral third country is sometimes chosen when both parties distrust each other's home jurisdiction. If a Nigerian company and a German company cannot agree on Nigerian or German law, they might choose Swiss or Singapore law as neutral ground.

What to Avoid

Choosing the law of a jurisdiction with an underdeveloped commercial law. Some founders default to the law of their company's country of incorporation. If your company is in Georgia or Paraguay, that may not be the best choice for a complex service contract, as the commercial case law in those jurisdictions is less developed than in England or Singapore, which creates uncertainty.

Choosing a different governing law and jurisdiction without a reason. If your contract says it is governed by the law of England but disputes must be resolved in Nigerian courts, you have created a situation where Nigerian judges must apply English law, possible, but costly and unpredictable.

Forgetting about consumer protection. The freedom to choose governing law applies to B2B contracts between commercial parties. If you are contracting with consumers, many jurisdictions have mandatory consumer protection laws that apply regardless of what your contract says. A UK consumer's rights under the Consumer Rights Act 2015 cannot be contracted away by specifying a different governing law.

Vague or contradictory jurisdiction clauses. "Disputes shall be resolved in the courts of England or any other competent jurisdiction" is not a jurisdiction clause; it is an invitation to argue about the forum indefinitely. Be specific.

A Practical Framework for Founder Contracts

For most internationally mobile founders running service businesses, consultancy, SaaS, digital agencies, and professional services, the following approach is workable and proportionate:

For B2B contracts with EU or UK clients: English governing law, English courts or LCIA arbitration. Straightforward, widely understood, commercially respected.

For B2B contracts with US clients: New York or Delaware governing law, with AAA or JAMS arbitration if the contract value justifies it. For smaller contracts, a simple English or New York law clause with jurisdiction in the same place is sufficient.

For B2B contracts with Asia-Pacific clients: Singapore law, SIAC arbitration. Clean, enforceable across the region.

For B2B contracts with Middle East clients: DIFC law and DIFC Courts or DIAC arbitration if both parties are UAE-based; English law with LCIA arbitration for cross-border Middle East contracts.

For small contracts below £10,000–£20,000: The dispute resolution mechanism matters less; the economics of litigation or arbitration rarely justify the cost at this level. Focus on clear payment terms, short payment cycles, and upfront deposits rather than elaborate dispute resolution provisions.

The Minimum You Should Have in Every Contract

Even a simple one-page service agreement should contain:

1. A governing law clause: one sentence specifying which country's law applies
2. A jurisdiction clause: which courts or arbitral bodies have authority to hear disputes
3. Clear payment terms: amount, currency, due date, late payment consequences
4. A scope of work definition: what you will deliver and when
5. A limitation of liability clause: capping your exposure to a defined amount
6. An intellectual property clause: who owns what once the work is done

The governing law and jurisdiction clauses are the framework within which everything else is interpreted. Getting them right costs almost nothing. Getting them wrong, or not having them, can cost a great deal.

When to Get a Lawyer Involved

For contracts above a meaningful threshold, and what is meaningful depends on your business, but £10,000–£25,000 is a reasonable starting point, having a qualified commercial lawyer review or draft your standard terms is worth the cost. A good template set of terms and conditions, drafted once and reused, pays for itself quickly.

For contracts with large enterprises, government bodies, or institutional clients, do not sign their standard terms without review. Large organisations' standard terms almost always favour them on governing law, jurisdiction, limitation of liability, and intellectual property ownership.

For ongoing cross-border relationships with significant commercial value, consider having a qualified lawyer in the relevant jurisdiction review your terms annually as laws change.

When your company is in one country, your client is in another, and you are living somewhere else entirely, the law governing your contract does not sort itself out automatically. It is determined, clearly and in advance, by your governing law clause, or messily and expensively after a dispute, by conflict of laws rules.

Choosing English law for international commercial contracts, pairing it with a clear jurisdiction or arbitration clause, and reviewing the arrangement for any significant new client relationship is not complex legal work. It is basic commercial hygiene that protects everything else you are building.
