When a new county shall be organized, in whole or in part from an organized county, or from territory attached to such organized county for judicial purposes, all the records of deeds and other instruments relating to real estate in such new county, may be transcribed into the proper books by the register of deeds of such new county; which records so transcribed, shall have the same effect in all respects as original records, and the register shall be paid for transcribing the same, such sum as the board of supervisors of his county may deem just and reasonable.
