Few moments in a relocation are as jarring as discovering that the people who manage your money will no longer have you as a client. It feels personal, and it lands precisely when your financial life is becoming more complicated. But the reasons are almost always structural, and understanding them turns an unwelcome letter into a manageable transition.
This article is for people moving between the UK and the US in either direction who find that an adviser, brokerage, or bank can no longer serve them after the move.
Financial advice and investment services are licensed by geography. A US adviser is registered to serve clients in the US; a UK firm is authorised by the Financial Conduct Authority to serve UK clients. When you move, you can fall outside the licence under which your provider is permitted to act. On top of that, many custodians and banks restrict accounts held at a foreign address, and international information-sharing rules have made firms more cautious about serving clients abroad. The result is a wave of offboarding that has little to do with you and everything to do with where you now live.
Offboarding takes different forms, and it helps to know which you are facing. Some firms stop giving advice but let you keep the account; some freeze new investments while allowing you to hold or sell; some require you to move the account entirely within a deadline. A bank may close an account; a brokerage may restrict trading. The common thread is a loss of continuity at the moment you most need it - which is why the response should be deliberate rather than rushed.

The instinct is to find a new local adviser, but this often does not work for a cross-border household. An adviser in your new country may not understand the assets you bring from the old one; an adviser in your old country may not be licensed to serve you where you now live. Each gives competent advice within their own system and misses the half of your life that sits in the other. This is the structural gap that catches relocating clients: the problem is not a shortage of advisers, but a shortage of advisers who can see both sides.
The arrangement that fits a transatlantic household is one that is equipped, and permitted, to act across both systems - able to hold and advise on US and UK assets, aware of the treaty and there porting on both sides, and regulated appropriately for a client whose lifespans two countries. Educationally, the things worth looking for include the relevant regulatory permissions for your situation, genuine familiarity with cross-border tax and reporting, and the ability to keep your accounts on the right side of each country's rules rather than forcing an awkward fit.
Almost everything in this area is easier before the move than after. Confirming which of your existing relationships can continue, and lining up a cross-border arrangement for those that cannot, is far smoother while you are still a domestic client of both systems than once a closure deadline is running. The offboarding letter is much less alarming when you have already planned for it.
Consider a hypothetical client moving from the UK to the US who receives notice from both a UK investment platform and a UK bank that they can no longer serve a US resident. Rather than rushing to liquidate, she maps which relationships can continue, identifies a cross-border arrangement able to act across both systems, and transitions in an orderly way that preserves her positions and her reporting. The letters marked the start of a planned transition, not a crisis. This example is hypothetical and for illustration only.
Before the move, ideally. Lining up a cross-border arrangement while you are still a domestic client of both systems is far easier than reacting to a closure deadline.
A local adviser may not understand the assets you bring from your former country. Cross-border households usually need an adviser who can see both systems.
Some do, and others restrict trading or new investments. Policies vary, so it is worth confirming what each provider will and will not do before you move.
Usually because advice and investment services are licensed by geography, and your move can put you outside the licence under which your adviser is permitted to act.
