When Legal Advice Does Not Transfer: Doing Business Across Different Legal Systems

You can hold two entirely correct legal opinions from two competent firms and still be exposed, because neither was asked about the space between them. Each lawyer answers accurately within their own system. Nobody is retained to examine what happens where the two systems meet — and in cross-border matters, that is usually where the problem lives.

The reason is that legal advice carries unstated assumptions about how everything around the law behaves: how much weight a court gives to the written document, whether a judgment can be turned into recovered money, how a regulator uses its discretion, what a term of art actually means. Those assumptions are invisible to the person giving the advice, because within their system they are simply true.

This article sets out five assumptions that fail to cross borders, why appointing counsel in each country is necessary but not sufficient, and what to establish before signing. Nexus is not a law firm and does not provide legal advice — what follows describes the coordination problem, not the law.

Key Takeaways

• Two correct opinions do not add up to coverage. The interface between them belongs to no one unless someone is asked to own it.
• Winning and collecting are separate questions. Governing law and enforceability are decided in different places.
• Some legal concepts have no equivalent term. Accurate translation of a word can still misrepresent the obligation.
• Specify which language version controls. Two equally authoritative texts that diverge is a dispute waiting to be had.
• An agreeable response is not agreement in every business culture, and reading it as one is expensive.

Five Assumptions That Do Not Cross Borders

Five assumptions travel badly between legal systems. Each is reasonable at home, invisible to the person holding it, and capable of producing a serious surprise when applied somewhere else.

1. That the contract is the agreement

In some systems and business cultures the written document is understood as the complete and final statement of the deal. In others it records the current understanding of a relationship that is expected to keep developing, and a request to revisit terms after signature is normal rather than a breach of faith. Neither view is wrong; the exposure comes from two parties holding different ones without either realising.

2. That the same word means the same thing

Legal terms are products of the system that created them. Concepts such as trust, fiduciary duty, consideration, or good faith may have no direct equivalent elsewhere, or may exist with materially different consequences. A translator can render the word faithfully while the legal effect behind it simply does not exist in the other jurisdiction.

3. That enforcement follows judgment

Selecting a governing law and a forum settles where a dispute is decided. It does not settle whether the resulting decision can be turned into recovered money where the counterparty’s assets actually sit. Recognition of foreign judgments varies considerably, and arbitration awards frequently travel better than court judgments — a question worth asking before signature rather than during a dispute.

4. That the regulator behaves the same way

Regulators differ not only in their rules but in how they operate: how much discretion they exercise, whether informal guidance is available and how much reliance it deserves, how long approvals genuinely take, and how consistently policy is applied across offices. The written rule is public; the operating practice is learned locally.

5. That silence or agreement means agreement

In business cultures where direct refusal is avoided, a warm reception and an absence of objection can indicate politeness rather than acceptance. Foreign parties routinely report positive meetings that produced nothing, having read courtesy as commitment. This is a commercial risk before it is ever a legal one.

Advice does not fail at the border because it was wrong. It fails because the assumptions it rested on stayed behind.

Why a Lawyer in Each Country Is Not Enough

Appointing competent counsel in both jurisdictions is necessary and is not the whole answer. Each is engaged to advise on their own law, and doing so accurately is the limit of what they were retained for. The interaction between the two opinions is nobody’s scope, and the interaction is where cross-border matters usually go wrong.

Three gaps recur. Neither lawyer sees the whole structure — each reviews the part in front of them, and an arrangement that is sound in each jurisdiction separately can still fail as a whole. Neither is briefed on the other’s assumptions, so a provision drafted to work under one system may be interpreted quite differently under the other. And neither owns the commercial question, which is not what the law says but what will actually happen.

This is a specific instance of a more general pattern: problems that cross disciplines belong to no single professional brief. We examine that pattern in When Standard Solutions Fail: Why Complex Situations Require Specialized Advisory.

What Gets Lost Between Languages

Translation problems in cross-border work are rarely about vocabulary. They arise where a concept has no counterpart, where a phrase carries a commercial implication that does not survive the move, or where two language versions of an agreement are both declared authoritative and quietly diverge.

• Specify the controlling language. Where two versions are equally authoritative and they differ, you have created the dispute rather than avoided it. Name one version as controlling and have the other prepared as a translation.
• Have the concept explained, not only the word. Where a term is central to the obligation, ask what it actually requires a party to do under local law, in plain language.
• Use interpretation rather than translation in negotiation. An interpreter conveys what was said. Commercial meaning — including whether a polite answer was a yes — requires someone who understands both business cultures.
• Read the local-language record. Corporate filings, court records, and land titles in Thailand are held in Thai. Diligence conducted only in English is partial by construction, as covered in Who Are You Really Dealing With? Have You Verified Their Credibility.

How to Structure Cross-Border Advice

The fix is structural rather than a matter of finding better lawyers. Someone has to hold the whole picture, put the same question to both sides, and be accountable for the gap between the answers.

1. Appoint a single coordination point. One party responsible for the interface, who receives both opinions and is expected to identify where they conflict or fail to meet.
2. Ask both sides the identical question. Written in one sentence and sent to each. Differently framed briefs are a common source of apparently contradictory advice, as set out in When Your Advisors Disagree.
3. Separate the three questions that get merged. Which law governs, where disputes are heard, and where a decision can be enforced are distinct and are often treated as one.
4. Have the practical consequence explained in plain language. Not the legal position, but what would actually happen: how long, at what cost, and with what realistic prospect of recovery.
5. Keep verification separate from legal work. Whether the counterparty is what it appears to be is a factual question, not a legal one, and the two should not be conflated.

What to Establish Before Signing

Six points are worth confirming as fact before a cross-border agreement is signed. None requires specialist legal knowledge to ask about, and each has ended or restructured transactions when the answer proved unsatisfactory.

• Governing law, forum, and enforcement path — all three, established separately, with a clear view on whether a decision would be recognised where the assets are.
• Controlling language version, stated expressly in the agreement.
• The signing entity holds what you are relying on — assets, licences, and contracts, rather than an affiliate outside the agreement.
• Signing authority under local rules, including any requirement for joint signature or a company seal.
• Any regulatory approval required for the structure, and whether it survives a change of control.
• What each party understands has been agreed, restated by both in their own words before signature. This unglamorous step catches more problems than any other.
