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.

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.

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.
