Ireland > Investment funds Tier 1

The team has advised a series of fund managers on the creation of Irish entities, bringing in its renowned financial services regulatory expertise. It continues to be active in the UCITS and non-UCITS segments, including consolidations in the UCITS field.

Sarah Cunniff is noted for UCITS and ICAV matters, while Ian Dillon, Dara Harrington, Cormac Commins and Siobhán McBean are also key members of the team.

Practice head(s):

Kevin Murphy; Tara O’Reilly


‘Other legal firms would do well to recognise that, more than ever, clients are looking at problem solvers, ideas, solutions, not simply translation of regulation and legislation. Arthur Cox delivers that.’

‘Experienced and proactive team, client oriented and caring for the client’s interests. Useful updates via e-mail – regular distributions as well as focused emails specifying relevance of the updated and timelines. Interesting and useful online seminars – also very focused on key topics, key updates. Just balances to not overdo with the information but keep good level of awareness.’

‘The Investment funds team at Arthur Cox is, I believe, amongst the most knowledgeable in the sector. Whilst that alone would make them a strong choice amongst their competitors, it is the way they deliver their service that stands out. From first engagement, to wrap up of the project, we received proactive assistance rather than solely formulaic legal advice. Proposals that are innovative, or unusual, are often given short shrift in financial services, due to the highly constrained regulatory environment, yet the team at AC didn’t simply dismiss the ideas, rather they worked hard to deliver the outcomes required.’

‘With particular reference to Sarah Cunniff and Tara O’ Reilly, both are dedicated to service excellence and uniquely client focused.’

‘Dara Harrington is a knowledgeable lawyer, with deep understanding of the European and Irish regulatory frameworks.’

‘We have worked with Cormac Commins for several years and really enjoy the business relations with him and his team. We, first of all, appreciate the proactiveness, focus on our needs and priorities but also, which is not less important, quick turnarounds with responses and being ready to provide support when it is needed at hoc. Professionalism and expertise go without saying – we had several complicated matters to resolve, and Cormac’s input and opinion were of real value and help.’

‘Cormac Commins was our first contact in the firm, remained our key adviser, and was responsible for selling the firm to us. From first contact to last, he understood our challenge, understood our constraints and, importantly, was happy to try and take us on the journey, rather than simply act as an adviser. An outstanding lawyer.’

‘Cormac Commins, and his associates, never ducked the issues. Where ideas were unworkable, they would tell us, and they could tell us because they have extensive knowledge and experience.’

‘The people on the pensions team are subject matter experts. When we ask them a question, their response is considered, comprehensive, timely and useful.

‘The team provide practical advice and solutions to day to day issues we face. For us this allows us to deal with the issues quickly rather than first having to decipher long legal opinions.’

The team also handles judicial review cases in the environmental sector, including challenges to the granting of industrial emissions licences. Another area of focus for the team is advising public bodies in these sectors on the regulatory issues surrounding developments. Danielle Conaghan leads the team, which also includes consultant Yvonne Scannell, a specialist in environmental law, senior partner Deborah Spence, who handles both planning and environmental disputes, senior associate Jacinta Conway and Laura Rafferty, who was promoted to of counsel in June 2021.

Practice head(s):

Danielle Conaghan

Other key lawyers:


‘The team truly understand their discipline. They offer me a perspective that I do not have and make me consider the advice I am receiving in a well-understood legal context. They make the client and others feel part of the wider team and at no stage do they make you feel you cannot ask any question, no matter how insignificant it may appear to you. They have dealt with us professionally and in a responsive manner, ensuring we stay in control of the situation. The team reflects diversity; there is a strong lead from women and a feeling of equality in the team.’

‘This is a very strong team with the very particular, highly sought-after skill of being strategists for litigation avoidance in this highly litigious area. From our experience, there are a large number of highly skilled practitioners in this area but the ability of this team to anticipate and manage the potential risks of a challenge and to develop comprehensive strategies to avoid litigation puts them way ahead of other practitioners in this field. This team has very strong depth as we never have had to wait for any question or issue to be addressed, which is key when you are dealing with international construction projects.’

‘Danielle Conaghan is a clear star in this area and her continued ability to navigate through complicated scenarios for international clients, who are not familiar with the Irish system or the likely challenges that it can result in, makes her a leader in this area. I would also highly recommend Jeanie Kelly and Jacinta Conway. Jeanie, in particular, has demonstrated very strong leadership through her calm and solution-orientated approach, dealing with very emotional and stressed clients who have project deadlines which Jeanie understands and meets. Trying to explain this complicated area of the law to non-experts and develop strategies to address it is not an easy task but this team have consistently demonstrated their ability to do this.’

‘Laura Rafferty’s advice has been concise and effective. Laura has used her experience and knowledge of recent similar cases to our benefit and has also advised us of other cases with which we will be involved but had not yet been notified of. Laura has demonstrated an interest in our business goals and has worked hard to ensure that key deadlines have been met.’

‘A unique attribute of this team is the depth of knowledge within it. Our business encounters a wide and diverse array of issues on an ongoing basis and we are involved in a most contentious industry. The Arthur Cox planning and environmental team rise to and above the challenge on a consistent basis. Meetings are always facilitated and the necessary people are always available and present. If external parties are required, they are sourced and are present also. There is never a limit on capacity. Collaboration with others is never a problem and is in fact supported, when required or deemed beneficial. However, the Arthur Cox team are the nub of the solution. Access to excellent legal counsel is another unique attribute to the team.’

‘Every person I interact with in Arthur Cox is a pleasure to work with. Some of the issues we deal with can be heavy and sessions can be time consuming, therefore being comfortable in the presence of these people is very important. Each individual has a great depth of knowledge, underscored with a seemingly natural expertise in law itself. Their professionalism is taken for granted at this stage but it is worth mentioning as it is something which should be very much valued. Deborah Spence demonstrates all of the above and her positive influence on the team is very evident. Jacinta Conway is an extremely significant asset to the Arthur Cox team. Jacinta has demonstrated a knowledge capable of dealing with all and any issue presented to her, a really strong professionalism and a willingness to go the extra mile for her clients. Jacinta is also a pleasure to work with.’

‘Laura Rafferty has earned a reputation as the go-to in her field. Her background as a former barrister gives her an extra edge when it comes to managing the increasing amount of planning cases currently in the High Court. But it is her approach to clients that is most exceptional – she understands our business needs, is a clear and comprehensive communicator and develops trusted relationships. Laura is very passionate about achieving the best outcome, and this is evident in the value she brings and successes she delivers.’

‘Deborah Spence is thorough, a great communicator and a true problem solver. Yvonne Scannell is exceptional, an original thinker and with experience that is second to none. Danielle Conaghan is a star – articulate, knowledgeable and highly motivated.’

Practice head(s):

Aaron Boyle; Caroline Devlin


‘Professional, hard working and enthusiastic’.

‘We value Caroline Devlin and Robert Murphy for their knowledge and expertise in helping clients resolve their issues.

‘I attribute Arthur Cox’s success to the team members. I am fortunate enough to engage directly with Caroline Devlin. Caroline has taken the time to understand our business and its intricacies so she may offer the very best in legal advice, compliance, and legal and corporate agreements. The resourcing in strong in Arthur Cox, as when we do not require the high level of expertise that Caroline brings, she introduces us to a relative junior member of the team who can assist with lower-level legal advice and action. Similarly, Caroline introduced our business to Arthur Cox’s Northern Ireland office when we had an out-of-jurisdiction matter to resolve.’

‘Caroline Devlin often engages with our business outside office hours, including Saturdays and Sundays, when dealing with a particularly complex matter. She listens to and breaks down our requirements, so she is sure that she understand the challenge. She is measured, methodical and clear in her responses.’

‘Strong in-depth knowledge of transportation sector and financing.’

‘Every member of the Arthur Cox team working with us is knowledgeable and thus they were very important in the implementation process.’

‘They are committed to the project we are working on. Even though you know that they have many other things going on at the same time for other clients, from their commitment to the process, you would think that they were only working on your transaction.’

‘Aaron Boyle and Niamh McGovern were both excellent. They were able to explain issues simply and succinctly and with an overall commercial mindset.’
