Christoph de Weck, Director

Christoph has more than 30 years of experience in the financial services sector. He is admitted to the bar of the Canton of Zurich and the State of New York.

At the beginning he worked as a lawyer in commercial law firms in New York and Zurich.

He then moved to the fiduciary department of the audit firm STG-Coopers & Lybrand, where he managed the trust and fiduciary units as a partner at the Zurich office and was responsible for legal & compliance for the fiduciary area in Geneva. This was followed by a position in the legal service of Credit Suisse Trust. This led to the taking over of the functional management of the financial planning units of the six private banks in the Business Area Private Banks of UBS Group. Christoph de Weck thereafter headed the Financial Planning business unit at Dresdner Bank (Schweiz) AG with teams in Zurich and Geneva. He then moved to the Morgan & Morgan Group in Zurich as General Counsel, where he was responsible for Legal & Compliance. This was followed by a position as Legal & Compliance Officer for the trust company of the Pictet Group in Geneva. For the last five years he worked as a member of the management team of Swiss Life (Liechtenstein) AG, where he was responsible for legal cases, compliance and data protection.

These activities gave him a comprehensive insight into the legal and compliance issues of financial planning, especially regarding the trust, fiduciary and insurance areas. His experience in Liechtenstein is particularly valuable in relation to the development of European law, which Switzerland is now increasingly taking over. He is familiar with the analysis of complex customer structures because he set up such structures himself and was responsible for the “client-onboarding” process. He is also very familiar with the cross-border issue, as he was confronted with this problem both in Switzerland for an external asset manager and in the EEA for an insurance company.

Christoph is trilingual and a member of STEP and the American Bar Association.

He has given lectures at STEP conferences and has published articles in specialist journals.
