Whaling magnate Anders Jahre denied owning a fortune abroad, and Norway spent 30 years after his death recovering about 1 billion kroner

Anders Jahre founded his shipping company in 1922 and the Kosmos whaling companies from 1928. He funded about half of Sandefjord's city hall and two foundations at the University of Oslo. All his life he denied holding a fortune abroad. Records later traced a Panama company formed in 1939 that became Continental Trust Company and, in 1976, a Caribbean trust^†. He died in 1982, aged 90, with about $80 million abroad^†. The state filed a tax claim against his estate in 1984. Information emerged that former employees had helped hide the money. In 2000 the estate sued Bjørn Bettum, his right-hand man and successor at Kosmos, in Drammen district court. Bettum died in 2002^†. In 2002 the state partly won, and part of the fortune came back from the Cayman Islands. The estate believed a Cayman fiduciary, Thorleif Monsen, had moved the money into his own name. Monsen's son-in-law handed over documents in exchange for 40% of the net recovery. In 2008 the Monsen family paid $10 million to settle a claim of about $250 million. Lawsuits in Norway, England and the Caymans brought in about 1 billion kroner. Lawyers and other costs took 450 to 480 million. The case closed in Sandefjord on 12 June 2012. The state, Sandefjord and Vestfold county received about 400 million kroner. Jahre had no children^†. In 2026 the University of Oslo still awards the Anders Jahre medical prize of 1 million kroner.
