About us

Our services

“They are absolutely, without a doubt, one of the strongest boutique firms in terms of knowledge and practice.”

Client: Chambers High Net Worth UK 2023

We have unrivalled international expertise – as we can uniquely offer both England and Wales, and Hong Kong, law advice on the ground in London. We aim to provide the best possible service to our clients – whether they are facing marriage or relationship breakdown, and disputes relating to children – or if there is a commercial element, and the clients are trustees of offshore or onshore trusts.

We have acted in a number of the highest value and most complex international cases in London and Hong Kong, and have been pioneers in making ground-breaking new law – including on financial, surrogacy and medico-legal/fertility law issues.

We are leaders in the field acting for trustees in divorce and trust cases, where divorce proceedings are filed either in London or Hong Kong: in the landmark Hong Kong Court of Final Appeal case of Otto Poon – in which Marcus Dearle led the team acting for the trustee – the Financial Times reported that the case had, ‘Rattled the Trust Industry’.

We have recently acted for Sir Frederick Barclay in a leading high profile case relating to a web of highly complex overseas trust arrangements.

We lead from the front: where the client has unimpeded access to the partner – and the partner fronting the case always has a genuinely hands-on role.
