The Facts

Why cross‑border businesses need legal support

Without expert support, dealing with multiple legal systems across jurisdictions, time zones and languages can quickly inflate costs, introduce risk and cause significant delays for your business. With Complex 360, you have an experienced team on hand to provide straightforward advice on contract terms, enforcement, compliance, litigation, and more – backed by a global network of in-country counsel.

The law

What laws apply to cross-border business?

Cross-border claims may fall under the jurisdiction of multiple countries, which can introduce ambiguity when it comes to the recognition of rights or the enforcement of contracts or judgments. Conflicts‑of‑law analysis and early enforcement planning are essential to minimise your legal and commercial risks, as well as clear advice on issues such as tax, employment or consumer laws.

The risks

What happens if we get it wrong?

Without coordinated counsel, including reliable local advice, cross-border legal issues can leave you exposed to disputes, unable to enforce contracts, or subject to fines or penalties. From an operational point of view, legal hurdles can cause project delays, waste leadership time, and damage trust with international customers or partners.

Frequently asked questions

If you don’t find the answer to your question here, get in touch with us and we’ll be happy to help.

How do you choose governing law and jurisdiction?

We work with you to assess the best governing law and jurisdiction based on your business objectives, the markets in which you operate, and any partnerships or supplier relationships. We’ll balance costs and enforceability against leverage and appetite for risk to develop a strategy that works in your interests – as well as drafting contracts and recommending court or arbitration options where needed.

Can you run disputes across multiple countries?

Yes, many of our clients have business interests in more than one other country, and we’re experienced in handling multiple cross-border claims in parallel, or those which span two or more jurisdictions. With Complex 360, you’ll have access to a named contact in the UK who will coordinate local counsel in the relevant countries, work with you on strategy and objectives, and manage communications and evidence gathering on your behalf, as well as manage the process for court actions or arbitration if needed.

What about compliance for sanctions, exports, and data?

Cross-border movement of goods and services, transactions, and data transfer can be complex in terms of regulatory compliance and navigating legal restrictions – and the more jurisdictions involved, the higher the risk. Complex 360 makes it simple – reviewing your business activities against the relevant laws, ensuring contracts or purchase orders are screened for compliance, and advising on data protection and transfer standards, so you can be confident that you haven’t left yourself open to legal claims.

How do you keep costs predictable?

Complex 360 gives you full transparency over costs: in most cases, the legal support you receive for cross-border claims is covered by your usual monthly retainer. In cases where you need additional services outside your planned allowance, we’ll discuss this with you in advance and provide a clear breakdown of any fees. Depending on the details of the case, we may be able to offer fixed-fee or staged payment structures to reduce the immediate impact on your budget.

What does Complex 360 add beyond local lawyers?

Our service isn’t just about putting you in touch with local counsel; we offer wrap-around support from instruction to resolution. As a member of Complex 360, you’ll receive dedicated, plain English legal advice from a UK-based team, personalised to the unique needs of your business. We’ll manage the relationship with outside counsel where needed, and represent you in interactions with regulatory bodies or legal systems, allowing you to focus on business as usual. From legal strategy to documentation, negotiations, and court action, our aim is to make each cross-border claim as straightforward as possible and secure the best outcome.
