The current Romanian royal family (of Romania, formerly named of Hohenzollern-Sigmaringen), an integral part of the larger royal house of Romania, consists of the family of former King Michael of Romania who bears a royal title (i.e. Royal Highnesses). There is also an illegitimate non-royal branch which descends from Michael's older half-brother Carol Mircea Hohenzollern (also known as "Carol Mircea Grigore of Romania", al României in Romanian, on his amended Romanian birth certificate), whose members have never been recognised as part of the royal family by King Ferdinand, King Carol II or by King Michael. The former king, former queen and their five daughters renounced publicly any claim to the defunct titles Prince and Princess of Hohenzollern.
The children of Princess Elena, Princess Irina, and Princess Sophie have no rights to the Romanian throne according to both the defunct royal Constitution of 1923 and the defunct Law of the Statute of the Romanian royal house dated 1884. On December 30, 2007 in a private ceremony, King Michael signed into effect a new such Statute,  an act with eminently symbolic importance in the absence of its approval by the Parliament requested by Michael himself, in an attempt to replace the old 1884 Law of the Statute. Through the new Statute called Fundamental Rules of the Royal Family of Romania, Michael decreed his grandchildren into the line of succession to the throne and to the headship of the Royal House and explicitly banned any other foreign prince belonging to any other royal or princely house from succeeding. On the same occasion he asked the Romanian Parliament to change the Salic law should it consider restoring the monarchy (see "Line of succession to the Romanian throne"). Through the same act, Michael also designated Nicholas de Roumanie Medforth-Mills as a future member of the Royal Family and future "Prince of Romania" with a "Royal Highness" style effective either on his 25th birthday, April 1, 2010, or upon Michael's death, whichever occurs sooner. Children or consorts of the members of the royal family of Romania who do not bear a Royal title, are not recognized as members of the Royal Family according to the new rules, but only as members of the larger family of King Michael I and of the Royal House.
