Early life
Frick was born on 8 May 1965 in Chur to trustee Kuno Frick and Melita Kaufmann as one of six children. From 1977 to 1985 he attended high school in Vaduz and proceeded to study law in University of St. Gallen, where he received a diploma in 1989 and finished his doctor thesis 1992.
He was a member of the Balzers municipal council from 1991 to 1993.
Prime Minister of Liechtenstein
Frick was the Deputy Prime Minister of Liechtenstein from May 1993 under Markus Büchel until he resigned in October under pressure from the Progressive Citizens' Party after the Landtag of Liechtenstein withdrew its confidence in him, and Frick became Prime Minister of Liechtenstein. Hans-Adam II subsequently called the October 1993 Liechtenstein general election which resulted in a win for the Patriotic Union. He became Europe's youngest head of government at the time at 28 years old.
During his tenure as prime minister, Liechtenstein entered the European Economic Area after a successful referendum in 1995, and also joined the World Trade Organization the same year.
His term in office also saw the conclusion of the VAT agreement with Switzerland (1994) and accession to the World Trade Organisation (1995). Liberalisation and privatisation took place partly as a result of EEA membership – in the telecommunications sector (privatisation and decoupling from Switzerland from 1998, and the launch of Liechtenstein’s mobile telephony service from 2000), and in the postal sector (amicable termination of the postal agreement with Switzerland in 1999 and the establishment of Liechtensteinische Post AG). There was also an opening up of the market to providers in the healthcare sector, the financial services sector, the commercial sector and the liberal professions (doctors, architects and lawyers).
However, it also faced problems in its foreign relations, such as a dispute with the Czech Republic begun in 1992 over the confiscation of Princely properties estates in 1945, and a 2001 dispute with Germany in the International Court of Justice over royal property confiscated in order to pay war debts.
In 1997, the Progressive Citizens' Party withdrew from the coalition government that had existed since 1938, making his second cabinet the first non-coalition cabinet since then.
Frick's government was faced with the challenge of the 1999–2001 Liechtenstein financial crisis, where the German Federal Intelligence Service accused various banks, politicians and judges within Liechtenstein of cooperating with organized crime to promote money laundering. These allegations were refuted, but it became apparent that cooperation in response to enquiries relating to the fight against money laundering needed to be significantly improved.
This led to Liechtenstein being blacklisted by the Financial Action Task Force in 2000. As a result, his government oversaw reforms to the Liechtenstein financial sector to combat organized crime and money laundering.
Legal career
Following his departure from government in 2001, Frick entered private legal practice and the fiduciary sector. In 2002, he became a partner at Advocatur Seeger Frick & Partner in Schaan, where he advises clients on banking and financial market law, corporate law, foundation and trust law, succession planning, asset protection, tax law, and administrative law. His practice focuses particularly on the regulation and supervision of financial institutions, including banks, insurance companies, undertakings for collective investment in transferable securities (UCITS), and alternative investment funds (AIFs).
In addition to his legal practice, Frick co-founded Trevalis Treuunternehmen reg., a Liechtenstein fiduciary and trust company, in 2002 and sold it in 2015.
He is a founding member of the Democracy Secretariat, which, particularly between 2001 and 2003, opposed the Prince’s proposed constitutional amendments at the time.
Frick was president of the Liechtenstein Bar Association from 2005 to 2014. During this time, the Bar Association was professionalized with its own office and the ABGB (“200 years of ABGB in Liechtenstein”) and various procedural laws (AussStrG, ZPO, StPO) were modernized.
In 2021, he qualified as a notary in Liechtenstein, adding notarial practice to his professional activities.
Frick has been active in Liechtenstein's financial sector through corporate governance roles. Since 2008, he has served on the board of Bank Frick & Co. AG, including as chairman of its board of directors.
Legal scholarship
Alongside his legal practice, Frick has published on Liechtenstein and international financial law. His scholarship has focused on banking regulation, blockchain legislation, trusts and foundations, asset protection, cross-border recognition and enforcement of judgments, private international law, and succession planning.
His publications have appeared in legal journals and edited volumes, including the Banking Regulation Review, Liechtenstein Journal, Jus & News, and the Handbuch des Vermögensschutzes. In 2022, he co-authored chapters on Liechtenstein's Blockchain Act and the country's banking law, reflecting the development of Liechtenstein as a centre for financial services and digital asset regulation.
Personal life
Frick married Andrea Haberlander (born 11 February 1965) in 1993. The couple divorced on 2 August 2024. On 10 July 2026, he married Christine Reiff.
Frick's brother Jürgen was shot and killed in the underground garage of Frick & Co. Bank in the town of Balzers on 7 April 2014. The shooter, Jürgen Hermann, later shot and killed himself, and his body was found in Lake Constance on the German side of the lake.
