The Communist regime of Hungary prevented him from pursuing his academic studies.

Later, he moved to Canada, where married Andrea Nikolits de Kékes in Ontario on 10 October 1982.

After the end of Communism in Hungary, he returned to his homeland and settled down in Nádasdladány, a former estate of his family.

According to the foundation and the Magyar Távirati Iroda (MTI), he was the last male member of the Hungarian line of the Nádasdy family; however, the family survives – after seven centuries in Hungary – among other in the United States with his first cousin, Count Gábor Nádasdy de Nádasd et Fogarasfold (born 1940), the next head of the House of Nádasdy.
