Practice Areas

Our passion has no limits

  • We advise domestic and foreign financial services firms, investors and other companies on all legal and regulatory issues relating to financial services and products in Switzerland. Profound knowledge and extensive professional experience in-house and as external legal advisors to asset managers, investment advisers, banking institutions and securities dealers enable us to deliver innovative, high value-added solutions.

  • Providing professional advice on the establishment, organization and administration (corporate housekeeping) of all corporate structures that are relevant in Switzerland is part of our daily business, along with the adequate structuring of the shareholders’ and/or owners’ participations. We navigate our clients through all areas of business contracts as well as selected transactions – both domestic and cross-border – in order to elaborate sustainable, economically viable solutions and, should need arise, by taking the appropriate legal action or defending your legal interests.

  • Entrepreneurs and private clients appreciate our holistic approach to issues of succession planning and inheritance law in general. We are prepared to act as executors of your last will as well as your representatives before Swiss courts or arbitral tribunals in connection with contested wills, inheritance agreements and estate administration.

  • Intellectual property rights (in particular copyright, patent, trademark, domain and design), together with the legal framework pertaining to competition, marketing and media, have become paramount in transforming ideas and inventions into successful business. Therefore, we assist our clients on a regular basis in selected areas in this context and represent them in any disputes that may arise.

  • We are prepared to protect our clients’ legal interests vigorously and independently in selected civil procedures before Swiss state courts and arbitral tribunals. The unique combination of our well-founded expertise and knowledge of the legal, procedural and economic principles to be observed is our key success factor in litigation and arbitration.

  • As long as corresponding mandates are in line with our business principles and professional/ethical standards, we are delighted to act as board members of Swiss corporations and foundations and offer domiciliary services.

My journey at Brunner & Partner started in 2013. I originally come from Ticino and I am studying law at the University of Lucerne. The atmosphere here at Brunner & Partner is exceptionally incentive: It`s a work place filled with passion for law yet calm and concentrated processes. “When you are in the right, you can afford to keep your temper; when you are in the wrong, you cannot afford to lose it.” (Mahatma Gandhi)

Gustav Radbruch said: “Law is the will for justice.” But actually law is so much more than that. My work enables me to see the various aspects of law even outside of my studies. As part of Brunner & Partner I am able to gain valuable experience as an assistant; at the same time I am being challenged and encouraged in my abilities of dealing with the questions and problems of law. Like Klaus Klages once said: “Every thing has two sides. With a lawyer three.”

I began working at Brunner & Partner in Sept. 2014, simultaneously with the start of my law degree course at the University of Zurich. The decision to study law was an easy one: while I was still in high school I already had the privilege of working at Brunner & Partner during my free time, where I was instantly fascinated by the world of law. All the better that I am now able to combine my passion for University and work.


We look forward to hearing from you
