The pair had been adopted later in life by Zsa Zsa and Frederic and were not blood relations.
Frederic had previously talked proudly of adopting people who paid him to have his royal title, despite the legitimacy of the title being openly questioned.
Reportedly, Frederic hadn't learned of the accident until he was contacted by the coroner on the evening of Dec. 26.
Frederic believed his son was in Germany still, TMZ reports.
Oliver immigrated to the United States 20 years ago and was a resident of Beverly Hills. His mansion there is currently for sale and carries a $4.8 million price tag.
His adoptive mother starred in several films, including "How The World Turns" and "Moulin Rouge."
The Hungarian actress endured a stroke before falling into a coma and dying of cardiopulmonary arrest at the Ronald Reagan UCLA Medical Center of Los Angeles.
The star had longstanding health issues. She fell into a coma after a 2002 vehicle accident, recovered from strokes in 2005 and 2007, had her right leg amputated in 2011 and endured a feeding tube-related lung infection in February 2016.
