As Senior Partner in Jersey, Nuno is one of the most highly regarded Jersey advocates. He has over 30 years experience and his profile has resulted in Collas Crill attracting some of the island's best known and most complex, top-flight litigation work.

Nuno is named in Legal 500's Hall of Fame UK lawyers list which identifies exceptional legal talent at the pinnacle of their profession.

Ranked in Chambers & Partners, Nuno specialises in commercial litigation and regularly represents clients in highly complex and important trust, contract and fraud cases many of which are now leading cases in their areas of law. The favoured advisor for many of Jersey's wealthiest families on their private, property and trust disputes, he has appeared in many substantial Jersey cases including acting for the first defendant in the Alhamrani trusts litigation, Jersey's biggest ever litigation dispute.

He is a Crown Advocate and has prosecuted a number of particularly high profile criminal cases; he regularly advises various departments of the Island's government (the States); and undertakes investigations arising out of complaints of discipline or misconduct against members of the Jersey Law Society. Few Advocates, whether in Jersey or in England, are able to work at the highest level of their profession in such a wide variety of areas.

Nuno was appointed Relief Magistrate in 2009 and continues to undertake that role and is one of the founding members of the International Fraud Group (IFG), a co-ordinated team of expert fraud lawyers (including Mishcon de Reya). The IFG enables multi-jurisdictional matters to be managed centrally, and his membership has led to his being instructed on several substantial international matters over the years.

Nuno's experience, at the highest level, is extensive and he has been instructed by a wide variety of clients, ranging from international financial institutions to countries.


My services
Contentious Trusts

We represent trust corporations, HNWIs, individual trustees and beneficiaries, often dealing with novel points of law and creating new and innovative solutions to fit the needs of our clients. Given the international scope of settlors, investments and assets, we often co-ordinate advice from our multi-jurisdictional teams, meaning that our clients benefit from the knowledge and depth of experience of our people around the globe.

Contentious Wills, Estates & Probate

We provide fast, cost-effective and sensitive advice on all manner of will related disputes during what is often an extremely upsetting and distressing time for those concerned. We regularly act on multi-party actions for both plaintiffs and defendants.

Director & Shareholder Disputes

Thanks to the depth of our experience and the resources of our team, we've acted on some of the largest pieces of litigation brought against directors offshore. We're well placed to deal with the 'bet the farm' proceedings that can occur in these type of disputes and have represented parties involved in intra-company disputes, including executive, non-executive and independent directors, majority and minority shareholders, companies and liquidators. We understand that shareholder disputes are often not simply 'black and white' and our team finds innovative and commercial alternatives to those which the Court may offer – taking a collaborative approach with our clients to ensure that the right result is achieved.

Dispute Resolution

When your business is involved in any kind of legal dispute it's crucial to work with lawyers who are hands-on, cost-effective and flexible enough to respond quickly and intuitively to your unique situation and needs. We know that there are many different ways a dispute can be resolved and work closely with our clients to understand every aspect of their business, priorities and goals. This allows us to find the best way forward for our clients and to advise on the commercial implications of a dispute, ensuring the process remains as stress-free as possible. Our approach is practical, responsive and tailored to the client's interests. Our expertise and reputation means we're first choice for a range of clients, including banks, trust companies, high net worth individuals and top law firms.

Fraud, Asset Tracing & Freezing Injunctions

At Collas Crill, we're used to working as part of a multi-jurisdictional team, capable of reacting and responding quickly to urgent requests for assistance with locating and freezing assets. As sophisticated defendants become more adept at dissipating assets, we've been involved in cases that created new law in the Channel Islands in relation to a party's ability to trace assets and recover their losses. With their ability to deal with complex issues the team deliver clear, commercial advice on the availability and likely success of recovery methods.

Insolvency & Restructuring

For financially distressed companies in need of restructuring and reorganisation, or for those where the opportunity to do so has passed or failed, Collas Crill’s insolvency and restructuring team work to achieve the most beneficial outcome in these difficult situations. 

Our team brings a wealth of experience from a range of diverse backgrounds to give quick, accurate, commercial advice, primarily across the financial services sector. 

Currently working on some of the largest and most complex cross-border insolvencies in the jurisdiction, we frequently advise top law firms from the People’s Republic of China, the United States, the United Kingdom and other jurisdictions. We are regularly briefed by Sovereign Wealth Funds and Fortune 500 Companies to advise on particular restructurings, as well as investment managers from Europe; the United States and Russia. 

At whatever stage we are engaged, our involvement will assist in identifying the on-going risks facing a client and to enable that client to continue to identify and to effectively manage deteriorating relationships with creditors, financiers, investors or other interested parties.

Private Client

As global legislation, regulation and taxation constantly change and become more complex, it has never been more important to make long-term plans to secure your future, the future of your family or your business. We cut through the legal jargon to provide clear, practical advice when you most need it and anticipate the challenges you are likely to face so that you can rest assured you and your family are in safe hands at every step of the way.

Relocate to the Channel Islands

Our team is ideally placed to advise on and project manage such a relocation, advising on everything from company migrations, housing licences and real estate matters through to introductions to other service providers and complementary local businesses.
