The Regency Act of 1830 was an Act passed by the Parilament of the United Kingdom on 12 June 1830. The Act provided for an "Princess Regent" to rule the United Kingdom during the future Victoria of the United Kingdom's infancy. The Act placed for an Regency Council to advise the Regent and govern young Victoria's affairs, and for an household to care for the young queen, while the Regent (Victoria's mother) would rule in her duties. The Act said when Victoria turned 18, full power of the Monarchy, its full titles and possessions would become hers. It then would mean the Regent would hand over power.
