International Expansion and Market Entry
Senior UK legal leadership for businesses building here, and for the growth that follows once they have. One named senior lawyer who owns the entire UK build, with a specialist law firm behind them and trusted counterpart firms wherever the work travels. Senior judgement, without the pyramid: on the ground, inside your chain of command, priced for the work.
Senior lawyers for international expansion and market entry
International expansion is rarely a single transaction. It is a sequence of decisions taken where the legal, regulatory and commercial ground is unfamiliar by definition, and the early ones compound: the wrong holding-company structure becomes a tax bill in year three, the wrong approach to authorisation costs nine months of trading, and a commercial template imported from another jurisdiction creates exposure no one priced. The work that decides whether an entry succeeds is done in the first weeks, before the structure is set, while there is still time to be deliberate.
There are two pieces of work here, and most clients need both in sequence. The first is the build: corporate structure, regulatory authorisation, governance and a working legal function. The second is the growth that follows: scaling the platform once it is in place, whether that is an international group reaching Europe, the Gulf and beyond, or a UK business expanding outbound into new markets. The two are held as one continuing relationship rather than reset at each stage.
Each of the usual routes asks you to accept a trade. A global office network gives you coverage, but continuity varies office by office and the premium is real. A separate local firm handles the task in front of it, though not the strategy across them. Running it in-house means learning the UK perimeter on the job, often while the business is already committed. Arbor is built differently: one named senior lawyer on the UK side who owns the relationship and the strategy, with trusted counterpart firms wherever the work travels. You stay in control, with one number to call, and no fragmented workstreams to manage yourself.
Most firms treat UK market entry as a transaction: complete the structure, obtain the authorisation, move on. Arbor is built differently. We get the whole business ready to run, beyond the move itself: the structure, the licences and regulatory authorisations the sector requires, the governance, compliance and the legal function, held on the UK side and managed by one named senior lead.
Once the UK operation is up and running, the same senior relationship continues through General Counsel Solutions, so the function you stood up does not lose its leader.
For financial services and fintech businesses, the relationship spans the full regulated lifecycle: from regulatory strategy and FCA authorisation, through ongoing compliance and governance, to the support required to operate, engage with regulators and grow with confidence. Most firms help you obtain authorisation. Arbor helps you build, operate and grow the regulated business that sits behind it. Arbor is one of the few law firms able to support SMF16 and SMF17 functions through outsourced managed compliance, ongoing compliance and financial crime programmes for regulated clients.
And when the business expands into new products, markets or jurisdictions, the relationship scales with it.
What you get when you instruct Arbor on an international or UK market entry matter
The advantage is not just having a senior lawyer for a transaction. It is having senior legal leadership, with the full support of the firm, throughout the whole journey: from the first decision through establishment, operation and scale. One relationship, one number to call, and a working model built around your business rather than the other way around.
A senior lawyer on the file from day one
A senior lawyer, chosen for the sector, personally leads the matter. The team behind them is senior too: lawyers who have negotiated cross-border deals at City and international firms and from the in-house seat. You will not be handed to a junior to draft the structure paper, then to a partner to approve the cover letter.
A bill you can defend internally
You get senior, City-trained expertise without the leverage and overhead that inflate a traditional firm’s bill. We agree the scope and fee envelope at the start of the engagement, including the work that sits with our international counterparts on the other side of the deal, so the total cost is visible up front. Most expansion matters fit a fixed-fee structuring phase, a capped-fee execution phase, or a phased model that tracks the milestones in the plan, with an hourly basis where that genuinely fits the work better. The right comparison is the total cost of the build, set against a global network’s blended team or a permanent UK hire made too early, and on that comparison the arrangement is straightforward to defend.
Advice calibrated to where you are in the expansion journey
A pre-Series B fintech entering the UK for the first time is solving different problems from a FTSE-listed group opening a fourth jurisdiction. The work that matters in year one is rarely the work that matters in year three. We tell you what to do now, what to leave for the next phase, and what the FCA, HMRC, Companies House and any other regulator that touches your business will look at first, including the governance overlay that connects the new entity back to the parent, the local partnership and distribution arrangements that need to work under local law, and the regulatory barriers worth mapping before the structure is set rather than after.
Sector context already on the page
We act for international financial services and fintech businesses entering the UK, payments and e-money firms, tech and telecoms businesses scaling across borders, infrastructure operators deploying across jurisdictions, media and media-tech businesses, and UK businesses going outbound into Europe, the US and the Gulf. We do not need a primer on what FCA authorisation expects of a US payments business, how a hyperscaler MSA changes when the contracting entity is in another jurisdiction, or where a UK tech business tends to get caught when it expands into the EU.
A straight answer on whether to do this, and how
Sometimes the expansion in front of you is not the right one for now, or the structure you are about to set up is not the structure you will want in two years. We will tell you that on the first call rather than wait for the meter to run. Where we are not the right firm for the matter, including where it is more international than UK, we will tell you that too and introduce you to a firm we know that is.
What the first phase of an expansion matter looks like
The shape of the first phase depends on the direction of travel and the sector, but the pattern is consistent across the most common starting points.
On an inbound UK market entry, week one is about scope: the activities you intend to carry on in the UK, the regulatory perimeter you will sit inside, the structure that supports the business model, the people who will hold any senior UK roles, and the interaction between your home-jurisdiction structure and what the UK will require. The output of week one is a short structuring paper covering entity, regulatory, tax (in coordination with your tax advisers), employment and commercial considerations, with a recommended sequence and timeline for the next twelve weeks.
On an outbound expansion from the UK, the first phase is about choosing the structure and the partners. We scope the priorities in the target jurisdictions, the regulatory permissions you will need, the people you will need on the ground, and the choice of local counsel. We coordinate directly with the lawyers we recommend so you do not lose time to onboarding conversations, and we agree the working model and fee envelope across the jurisdictions before the work starts.
On a cross-border deal that is more transactional than operational, including a cross-border M&A, joint venture or infrastructure deal, we run the UK leg end-to-end and act as the lead contact for the international counterparts. We work the deal calendar back from completion rather than forward from instruction, and we keep the commercial decisions in front of you at the right level of seniority rather than buried in cross-jurisdictional drafting threads.
