An Act for the better regulating the future Marriages of the Royal Family

In 1772 Parliament passed an Act which imposed conditions on how members of the British Royal family may contract a valid marriage. The Act states that no descendant of George II can marry without the consent of the reigning monarch. This Act is still in force today and since it was passed more than 100 marriages have been approved by the reigning monarch, including the recent marriage of Prince William and Catherine Middleton.
