(1)Subject to the following subsection, all such parochial registers as aforesaid shall, so far as they are not already in the custody of the Registrar General, be transmitted to him for custody in the General Register Office.
(2)Where a parochial register forms part of any other record or document or where for any other reason it would be inappropriate so to transmit the register, the duty to do so shall be discharged if there is transmitted to the Registrar General a copy of the register reproduced by photography, xerography or any other process approved by the Registrar General, or if an opportunity so to reproduce the register is afforded to the Registrar General.
(3)Notwithstanding the provisions of section 3(2) of this Act, it shall be lawful for the Registrar General to transmit to the Keeper of the Records of Scotland any parochial register or copy of such register, which is in the custody of the Registrar General by virtue of this or any other Act, if in his opinion the retention by him of that register or copy register is no longer necessary.
