About

As the movement of people, capital and businesses between the US and UK continues to grow, so does the complexity of operating across borders. Whether establishing or growing a business presence in the UK, relocating key personnel, resolving disputes or planning for future generations, US clients need legal advisers who understand both the opportunities and challenges that come with working internationally.

Our lawyers provide integrated advice across a range of practice areas that are frequently relevant to US-connected clients, including corporate and commercial matters, litigation and dispute resolution, employment, immigration, private wealth and UK tax. We regularly support US businesses entering or expanding into the UK market, advising on company formation, commercial contracts, regulatory considerations, workforce issues and strategic growth. We also work closely with internationally mobile individuals and families on residency, wealth structuring, succession planning and cross-border tax matters.

What sets Collyer Bristow apart is our ability to bridge the gap between the UK and US legal and business environments. We understand that differences in employment law, regulatory regimes, dispute resolution processes and business culture can create unexpected challenges for clients operating internationally. Our role is to simplify that complexity, providing practical, commercially focused advice that helps clients make informed decisions with confidence.

Collaboration is central to our approach. We work closely with a trusted network of US attorneys, accountants, wealth advisers and other professional contacts to ensure clients receive coordinated advice across jurisdictions. Through our membership of the Cross Border Lawyers Network (CBLN), we are also able to connect clients with high-quality legal expertise throughout the United States and around the world, delivering seamless support while maintaining the personal, partner-led service for which Collyer Bristow is known.

Whether you are a US business looking to establish or grow your UK operations, an entrepreneur pursuing international opportunities, or an individual with personal or commercial interests on both sides of the Atlantic, Collyer Bristow offers the insight, experience and connections to help you achieve your goals.

Dispute Resolution

Cross-border disputes often involve different legal systems, jurisdictions and commercial expectations. Our dispute resolution team advises US businesses, investors and individuals on a wide range of UK litigation and dispute-related matters, from commercial and contractual disputes to shareholder conflicts, professional negligence claims and fraud-related issues.

We understand the strategic considerations involved in disputes with a transatlantic dimension and regularly work alongside US attorneys to coordinate advice, manage parallel proceedings and deliver effective outcomes. Whether through negotiation, mediation or court proceedings, we provide clear, pragmatic advice designed to protect our clients’ commercial and personal interests.

Business Immigration

The ability to attract, relocate and retain talented people is critical to international growth. We advise US businesses establishing or expanding in the UK, as well as executives, entrepreneurs and high-net-worth individuals seeking to live, work or invest here.

Our business immigration team supports clients on sponsor licences, Skilled Worker visas, Global Business Mobility routes and other immigration pathways, helping organisations navigate a complex and evolving regulatory environment. We also advise individuals relocating from the US to the UK and work closely with our employment and private client teams to provide a seamless cross-border solution.

Commercial

Strong commercial relationships are fundamental to business success. Our commercial team helps US companies put in place the legal frameworks needed to operate effectively and manage risk in the UK.

We advise on a broad range of commercial agreements, including customer and supplier contracts, terms and conditions, consultancy arrangements, technology and software agreements, confidentiality agreements, partnership arrangements and outsourcing contracts.

With an understanding of both UK and US business practices, we help clients negotiate, draft and implement commercial arrangements that support their strategic objectives while protecting their interests. Whether launching a new venture, expanding operations or entering into key commercial relationships, we provide practical advice focused on achieving successful business outcomes.

Corporate

From market entry to strategic growth, we help US businesses establish, invest and expand in the UK.

Our corporate lawyers advise on company formation, acquisitions and disposals, joint ventures, shareholder arrangements, corporate restructurings, governance matters and investment transactions. We work with businesses at every stage of their growth journey, from founder-led companies entering the UK market to established organisations pursuing expansion, acquisition or investment opportunities.

By working closely with US counsel and other advisers, we ensure our clients receive practical, coordinated advice that reflects both UK legal requirements and wider international considerations.

Employment (labour) law

Employment law represents one of the most significant differences between the US and UK legal environments. From employee rights and discrimination protections to redundancy processes and termination procedures, US employers are often surprised by the extent of employment regulation in the UK.

We help US companies understand and navigate these complexities with confidence. Our employment lawyers advise on recruitment, contracts, workplace policies, executive hires, employee relations, investigations, restructuring exercises and exits. Working closely with in-house counsel, HR teams and US legal advisers, we provide commercially focused guidance that aligns with both UK requirements and the realities of international business.

Tax & Estate Planning

For internationally mobile individuals and families, tax and succession planning frequently extends across multiple jurisdictions. Our private wealth team advises US-connected clients on UK tax matters, estate planning and the ownership and transfer of assets.

We regularly assist individuals moving to or from the UK, those with family members in different jurisdictions, and those managing international property, investment and business interests. Working alongside trusted US tax advisers and attorneys, we help clients navigate cross-border tax considerations while developing structures and succession plans that support long-term family and wealth objectives. Our approach is practical, coordinated and tailored to the specific needs of each client and family circumstance.
