Legal 500 UK, The Client's Guide to Law Firms

Our highly experienced and multi-disciplinary team of lawyers offers a wide range of legal services for American expats and businesses to help protect all of their personal, family and business interests in the UK and overseas. In addition to providing legal services for US citizens while in the UK, we also advise on any legal matters involving cross-border wealth planning, investigations or other legal proceedings.

We advise in respect of the laws of England and Wales but we have an established network of trusted advisors in the US and in other jurisdictions with whom we can liaise on any issues involving cross-border collaboration and advice.

Our lawyers are renowned for their integrity and expertise in dealing with complex international cases, which are often high profile and sensitive.

Please expand the sections below for further information about our services and ways in which we can assist. 


We specialise in acting for entrepreneurs, owner managed businesses and investors in UK companies (many of whom are based overseas). We advise in relation to angel and VC investments, corporate transactions involving UK entities, banking, financing and on all aspects of running and growing a business. Much of the work we do relates to the technology sector, although we also regularly advise in the financial services, media, publishing and real estate sectors. Our priority is to provide creative and cost effective advice, focusing on the issues which are of specific concern to our clients.



We maintain a full-service criminal team dealing with the full range of criminal matters, from allegations of white collar crime to #MeToo investigations, from requests for mutual legal assistance or extradition to Interpol red notices - and everything in-between.

We are experience in dealing with cases in which both the United Kingdom’s and the United States’ authorities are involved. Such cases throw up complex challenges caused by conflicting rules on legal professional privilege, data protection and privacy rights as well as the different powers the investigating agencies have. Our understanding of these issues, our first-hand experience of the way the various law enforcement bodies co-operate and our excellent relationships with specialist Counsel and law firms in the US mean we can secure the best possible outcomes for our clients.

Our work on all kinds of hard-edged criminal investigations and our familiarity with the law enforcement agencies on both sides of the Atlantic means we are well-placed to advise on internal investigations involving both jurisdictions and UK compliance issues that a US company might have to address. 

We regularly act for US citizens who find themselves caught up in the English criminal justice system; discretely providing innovative, pragmatic solutions to complex and sensitive legal problems that affect their livelihood, business or reputation.

Nicolas Rollason heads our market leading corporate and private client immigration team.  We assist with UK bound applications, coordination of US inbound applications and global immigration applications. 

For UK bound immigration applications, we have excellent long standing relationships with senior contacts at the decision-making centres in the US.  Alongside our corporate and commercial law colleagues, we regularly assist US based corporate clients with establishing a UK presence and transferring staff to the UK.  Normally that is via Skilled Worker of the Points Based System and can involve expedited applications for a sponsor licence as well as efficient use of the Intra-company transfer scheme.  Where an existing US based senior employee is to set up the UK company, we can assist with a Representative of an Overseas Business application.  For private individuals based in the US, including entrepreneurs and HNW individuals, we can advise on the most appropriate route to move to the UK, including the Tier 1 (Investor) category, Start-Up/Innovator categories and applying as the partner of a British citizen as well as advising on any surrogacy and adoption issues.

Key members of our team are members of the American Immigration Lawyers' Association (AILA) and the American Bar Association (ABA) (for example, Marcia Longdon is a Human Rights & Immigration committee member with the Employment and Labor Section of the ABA).  We have strong working partnerships with specialist US immigration law firms which can assist with US-bound immigration matters.  We can project manage those applications and the advice in order to provide a streamlined and efficient service to our clients. 

Nicolas Rollason has led various talks in the US for AILA’s Global Migration Section.  He has also co-authored a chapter on global immigration policy trends for the International Comparative Legal Guides.

Our team of highly esteemed property lawyers are able to advise on all areas of real estate and construction law. We are well placed to assist clients with legal matters concerning their commercial and/or residential property interests in England and Wales.


wealth and tax planning

Our US clients, now permanently or temporarily  based in the UK, or with real estate here, regularly seek our advice on issues of:
  • Residence and domicile and their impact on tax and succession 
  • Succession to their UK assets and dovetailing arrangements with their US Will/lifetime trust
  • Exposure to UK taxes and the workings of the US/UK double tax treaty
  • Planning for UK inheritance tax 
  • The interaction of trust laws in the UK and USA and the differing tax treatment in each jurisdiction, liaising closely with clients' US tax/trust advisers.
A large part of America’s legal history is shared with England and Wales; laws and systems are complementary and US / UK Wills can be made to work in both jurisdictions.
While a client’s accountants can generally advise/ensure that income or capital receipts aren’t taxed twice, inheritance tax on UK assets (where US domicile is retained) kicks in at much lower levels that US estate taxes.
 We can offer careful and effective  advice for mitigating inheritance tax - usually at the point that a new family home is purchased in the UK, working closely with our real estate team to structure the purchase tax-efficiently.
