Prince Radu of Romania is the husband of Margareta of Romania, who is the head of the House of Romania and a disputed pretender to the former Romanian throne. On 1 January 1999, he was given the name, not title, of "Prince of Hohenzollern-Veringen" by Friedrich Wilhelm, Prince of Hohenzollern, the head of the Sigmaringen branch of the Hohenzollern family. He has also called himself "Radu Hohenzollern-Veringen-Duda". Since 2007, when he had his legal name changed from "Radu Duda" to "Radu al României Duda", Radu no longer uses the name of Hohenzollern. The Fundamental Rules of the Romanian Royal Family, proclaimed by former King Michael I on 30 December 2007, gave Radu the title of "Prince of Romania", with the style of "Royal Highness", which King Michael had given him earlier on 5 January 2005.

Margareta, Custodian of the Crown of Romania is the eldest daughter of King Michael I and Queen Anne of Romania. She assumed her father's duties in March 2016, upon his retirement, and has claimed the headship of the House of Romania since his death on 5 December 2017. She also heads the Margareta of Romania Royal Foundation.
