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, son of Georg Kieber and great-grandson of company founder Josef Ospelt, has also been the fourth generation of the family to work for Interadvice Anstalt. Philipp Kieber is a qualified Liechtenstein fiduciary expert and has been a member of the management team since 2016. Today he is the owner, a member of the Board of Directors and a member of the Executive Board of Interadvice Anstalt.
Anniversary year 2022
In 2022, 100 years will have passed since the early origins of Interadvice Anstalt. A special event will be held to celebrate and acknowledge this anniversary. It should be noted that it remains a family-owned business, even a whole century after it was founded.
Landstrasse 25, Vaduz
Our company premises located at Landstrasse 25 in Vaduz represent a rare example of Neo-Renaissance architecture in Liechtenstein. The property was designed by the Viennese architect Ignaz Bankó on behalf of the Chief Medical Officer and politician Dr Wilhelm Schlegel in the years 1879/1880. The building came to be named «Schlegelhaus» after its original owner. Ignaz Bankó, born in 1844, was appointed as the personal architect of Prince Johann II of Liechtenstein in 1871. Bankó came to Liechtenstein through his marriage to Helene Haus von Hausen, the daughter of Carl Haus von Hausen, who was the National Administrator at the time, and secured Liechtenstein citizenship in 1881. He oversaw construction of the parish church of St. Florin, the wooden porch of the «Löwen» tavern, which has since been removed, as well as the Princely Residence (all three located in Vaduz). Bankó was also responsible for the conversion of Wartenstein Castle in Lower Austria in 1881.
