How We Work With International Clients

Two advisers reviewing documents together at a meeting table

  • UK and cross-border advice

    We advise on the UK tax, structuring and trust position and how it interacts with the other countries in your life.

  • Your advisers abroad

    We work with your lawyers, accountants, bankers and trustees in other countries, including the ones you already use, so the advice fits together.

  • Senior-led from Mayfair

    A senior member of the team in our Mayfair office stays your point of contact throughout.

  • Complex matters coordinated

    Where a move, a sale and a succession plan all affect each other, we bring the pieces together and agree the order of steps with you.

What We Do and What We Do Not

A.C.T. London advises from our office in London on UK tax, structuring and other UK issues that arise in cross-border situations. Advice on the law and tax of other countries remains with appropriately qualified advisers in those countries, and we work alongside them.

We do not give immigration or visa advice. If you need it, we will suggest you speak to a regulated immigration adviser.
