Private client, trusts and tax in Guernsey

Carey Olsen

Russell Clark heads Carey Olsen's well-regarded trusts practice, which has close relationships with many of the island's leading trust services providers, London firms and high-net-worth individuals both on and off-island. Konrad Friedlaender's practice crosses over between traditional trusts work and pensions work, as does Natasha Kapp - both are originally qualified in South Africa. At counsel level, Patricia Montgomery's practice includes administration of local estates and Laila Arstall is notable for her tax expertise. Fellow counsel Wendy Lewis joined the team from an in-house role at SG Kleinwort Hambros. Senior associate Julie Currie is notable for her pensions expertise.

Russell Clark


‘Carey Olsen’s private wealth team is undoubtedly the strongest in Guernsey. They have a peerless breadth and depth of experience which allows them to deliver innovative solutions to the often times complex, multijurisdictional, problems facing offshore institutional trustees. They are technically brilliant, commercially savvy, and genuinely some of the nicest people you could have the pleasure of working with.’

‘Russell Clark is an exceptional lawyer. He’s quite literally written a large part of Guernsey’s trust laws and has been deeply involved with the development of Guernsey’s fiduciary industry.  He immediately understands the crux of matters he advises on, and delivers elegant and cost effective solutions.’

‘What Konrad Friedlaender doesn’t know probably isn’t worth knowing.’

‘Natasha Kapp’s views on legal questions have prevailed at the Privy Council over those of leading Chancery silks. She delivers incisive, lucid advice and is my first choice to protect the interests of a trustee in court.’

‘Laila Arstall is one of the Channel Islands’ premier technical tax practitioners; and her knowledge of all things tax related is compendious. Her advice is carefully reasoned and invariably excellent. Where there is ambiguity in legislation or regulation, she adeptly identifies the key concerns and assists the trustee to adroitly navigate them.’

‘Wendy Lewis has relatively recently joined the Carey trusts team from its litigation team; and has had the benefit of working as in-house legal for one of Guernsey’s largest fiduciaries. She is a strong litigator with a developing expertise in trust matters.  Her advice benefits from her time in house, and is cast with an eye for the commercial factors that invariably challenge in-house counsel.’

Collas Crill

At Collas Crill, group partner Angela Calnan heads the practice, which among work streams coming from closer by and Asia is particularly well-connected in the Middle East (with some mandates involving the region's free zones), where it advises on private trust company structures among other means of new systems. Fellow group partner Joanne Seal heads a wills and estates practice that has expertise handling the affairs of island residents and non-residents. The team was also bolstered by the recruitment of David Cooney, who joined in March 2020 from the Zürich office of Charles Russell Speechlys AG. Pensions are another area of expertise. Cerisse Fisher is a key senior associate in the team.

‘The Guernsey team that I work with are practical, responsive and it’s always a positive experience working with them.’

‘The Guernsey team are very capable. They are my go to choice if ever I need assistance on a Guernsey Law issue. Strong technical knowledge of both Guernsey and Jersey law and their interaction with other jurisdictions.’

‘The team are all technically excellent while also showing the rare commodity of being able to relate to a client and their adviser’

‘Angela Calnan remains a star and stand-out performer in the non-contentious trust field. She not only has a good knowledge of the relevant law, she also appreciates the practical and commercial considerations.’

‘Joanne Seal has excellent technical knowledge whilst being approachable and diplomatic.’


At Mourant, practice head Matthew Guthrie's recent mandates have included non-contentious and semi-contentious matters, including the relocation of structures to Guernsey, the creation of new structures and succession planning. Senior associate Sophie Denman qualified into STEP in October 2019. Some recent highlights have featured cross-border elements with continental European elements, and the team is well connected among the broader range of service providers on-island. Away from international trusts work, Mark Torode, who also handles real estate deals, is active in terms of non-contentious on-island wills issues. Previously a senior associate in the team, Chris Duncan is now a counsel at Carey Olsen in the Cayman Islands.

‘Mourant’s trusts team in Guernsey is very good. They are led by a very capable partner who invests in developing the team and ensuring that there is a selection of lawyers at various levels of seniority.’

‘Matthew Guthrie is currently the best non-contentious trust lawyer working in Guernsey. He also has a very good grasp of UK/offshore tax issues on which he does not advise, but does provide a steer and recommend others when he spots a potential issue. He is always available when needed, which is fantastic for his clients. He is utterly approachable and pitches his explanations at the level needed by his clients, adapting easily and as required.’
