Dr. iur. Hannes Arnold M.B.L.-HSG, Attorney at Law – Senior Partner

Senior Partner Dr. Hannes Arnold talks about the major challenges for a modern law firm and the path GASSER PARTNER ATTORNEYS AT LAW has taken to meet and overcome these challenges.

What do you see as the main points that differentiate GASSER PARTNER ATTORNEYS AT LAW from your competitors?

GASSER PARTNER ATTORNEYS AT LAW is one of the largest and most renowned law firms in Liechtenstein. We have an excellent reputation, earned through years of hard work in the best interest of our clients. The prerequisite and guarantor for this success is our team and therefore we attach great importance to the selection of outstanding lawyers who contribute to our firm both professionally and personally. In addition, one of our key concerns is to promote the professional development of our younger lawyers, who have the chance to reach a very high degree of specialization, be it in the field of foundation law, litigation or financial markets law. This certainly sets us apart from local competitors and enables us to deliver our best work in complex international cases through interdisciplinary teams. We are in a position to offer truly comprehensive legal advice in all areas of Liechtenstein law and to guarantee absolute expert knowledge in every practice area. Furthermore, our many years of activity have enabled us to build up a worldwide network from which our clients benefit.

Which practices do you see growing in the next 12 months? What are the drivers behind that?

We are in the privileged position of being able to assist a large number of clients in all areas of business law from litigation to financial markets law and M&A. We are pleased to observe that the Liechtenstein financial center is continuously growing, especially in the areas of fintech, insurtech and investment funds. As we advise a number of international and local financial service providers and institutions, these are definitely practices that are growing. From our very own perspective, we are delighted to see our newly established trust business growing and taking shape. It enables us to add a new facet to our activity profile and subsequently offer additional services to our clients. Accordingly, in addition to the high demand for legal advice, we also expect strong growth in this area.

What’s the main change you’ve made in the firm that will benefit clients?

We pursue a holistic approach in our strategy and constantly search for improvement. Against this background, it was as an extraordinary opportunity for us to broaden our offer with regard to trust services and to acquire the Liechtenstein fiduciary business of one of the biggest swiss banks in 2022. Due to the long tradition of advising families and private clients (in particular high-net-worth individuals) in asset planning and inheritance law, this recent step fit perfectly into our business model. Clients will continue to benefit from the best service, the high knowledge and experience and the same quality they are used to. GASSER PARTNER Trust Reg. will advise families and offer corporate services for handpicked clientele and tailormade structures.

Is technology changing the way you interact with your clients, and the services you can provide them?

Individual client attention and communication is a central cornerstone of our interpretation of our profession and appropriate security measures have high priority. However, as technology advances, of course many new ways of interacting with our clients emerge. Just think of the major challenges of recent years, which have massively restricted personal contact. I think we have mastered this challenge quite well and have found the right balance.

Can you give us a practical example of how you have helped a client to add value to their business?

Probably the best example in this context is the fact that we not only advise clients on specific projects or individual queries, but in many cases accompany them on their journey from the very beginning. A reliable and trustful continuing cooperation yields the best results and this is where we are particularly strong. This is also where our interdisciplinary teams create added value, because we can provide consistent, high-quality advice on everything from the establishment of the business, through complex transactions and contentious matters to succession planning.

Are clients looking for stability and strategic direction from their law firms – where do you see the firm in three years’ time?

Even in the face of growth, newly established fields of activity and the accompanying changes, we are always aware of our responsibility towards each and every individual client. Clients want and deserve full commitment and reliability. In the coming years we will keep working to sustainably grow our firm, retain our highly talented and motivated team, attract new talent and continue to successfully develop and integrate our fiduciary business.
