Welsh Church Act 1914

(1) Property which does not belong to and is not appropriated to the use of any ecclesiastical office or cathedral corporation, but which is, or is the produce of, or is or has been derived from, property which became vested in the Ecclesiastical Commissioners before the passing of this Act, and which immediately before becoming so vested belonged to or was appropriated to the use of an ecclesiastical office or cathedral corporation in the Church in Wales, or the holder of any such office as such.

Any property situate in, or issuing out of property situate in, Wales or Monmouthshire which has been purchased by the Ecclesiastical Commissioners shall be deemed to have been purchased with the proceeds of sale of and so derived from property which immediately before being vested in the Ecclesiastical Commissioners belonged to an ecclesiastical office or cathedral corporation in the Church in Wales, and the produce of such last-mentioned property shall be taken as having been diminished by the amount expended by the Ecclesiastical Commissioners on such purchases.
