The Duchy of Cornwall Act 1812 (52 Geo 3 c 123) is an Act of the Parliament of the United Kingdom. It is a public general Act. It was omitted from the third revised edition of the statutes because of its local and personal nature. This Act was partly in force in Great Britain at the end of 2010. The whole Act, except sections 6 to 9, was repealed by section 1(1) of, and Part IV of Schedule 1 to, the Statute Law (Repeals) Act 1978.
