After leaving government, Josef Ospelt, Liechtenstein’s first Prime Minister and Princely Counsellor, opened a law and insurance firm at the present-day head office in Vaduz on 20 October 1922. This meant he founded one of the first companies in the field of financial services in Liechtenstein. Later, Princely Councillor Josef Ospelt also became a parliamentarian, President of the Constitutional Court and a member of the Supervisory Board of Liechtensteinische Landesbank AG.
1962 to 1991
In 1962 Dr. iur. Willy Ospelt continued to run the business following the death of his father. In addition to his work as a lawyer and fiduciary, he too held numerous honorary appointments. Whether as administrator of Liechtenstein’s Volksblatt newspaper, Chairman of the Board of Directors of Skilift AG Vaduz-Malbun, President of Caritas Liechtenstein or President of the Vaduz Winegrowers' Cooperative, Willy Ospelt was a driving force throughout his life.
The company remained in family hands following the death of Dr Willy Ospelt. The husband of Willy’s niece Marina, Georg Kieber – himself a fiduciary and TEP (Trust and Estate Practitioner) – has run the company since 1991 fully in the spirit of his predecessors. He gave the company a new structure in 1991 when he founded Interadvice Anstalt as a family-owned, licensed Liechtenstein fiduciary company.
Since 2005, Philipp Kieber has been the fourth generation of the family to assume responsibility for the business. Georg Kieber’s son is a qualified Liechtenstein fiduciary expert, and since 2016 the second Managing Director of Interadvice Anstalt as well as the owner and Managing Director of LieAdvice AG, which he founded.
Landstrasse 25, Vaduz
Our company headquarters located at Landstrasse 25 in Vaduz is an Art Nouveau building constructed in 1880 according to the plans of the Viennese architect Ignaz Bankó. Bankó was the personal architect of Prince Johann II of Liechtenstein. Ignaz Bankó was born in Vienna in 1844. Through his marriage to Helene Haus von Hausen, the daughter of the then National Administrator Carl Haus von Hausen, Bankó found his way to Liechtenstein and became a citizen of Vaduz in 1881. Ignaz Bankó also oversaw construction of the Parish Church St. Florin in Vaduz.
The owner and first occupant of this historic building was the practising physician and politician Dr Wilhelm Schlegel.
