The Regency Acts are acts of the Parliament of the United Kingdom passed at various times, to provide a regent in the event of the reigning monarch being incapacitated or a minor. Prior to 1937, Regency Acts were passed only when necessary to deal with a specific situation. In 1937, the Regency Act 1937 made general provision for a regent, and established the office of Counsellor of State, a number of whom would act on the monarch's behalf when the monarch was temporarily absent from the realm or experiencing an illness that did not amount to legal incapacity. This act, as modified by the Regency Acts of 1943 and 1953, forms the main law relating to regency in the United Kingdom today.
