When in 1945 the Czechoslovak authorities confiscated the estate of the Princes von und zu Liechtenstein, the two countries became involved in a dispute which had not been resolved until recently, at least on a diplomatic level. For several decades, the 1948 Communist coup d'etat in Czechoslovakia dashed the hopes of the Liechtenstein family for a restitution of their confiscated assets.
However, officials responsible internally admitted that the property confiscation had been questionable in the case of the Liechtenstein family. The court had not confirmed the confiscation until after the Communist coup.
However, the Liechtenstein family did not renounce their claims, and after the collapse of the Communist regime in 1989 they brought them up again.
