A will of real property, which has been at any time, either before or after this Code takes effect, duly proved in the district court, with the certificate of proof thereof annexed thereto or indorsed thereon, or a certified copy of the will, may be recorded in the office of the recorder of deeds in the judicial division in which the real property is situated, in the same manner as a deed of real property. Where the will relates to real property, the executor or administrator, with the will annexed, shall cause the same, or a certified copy thereof, to be so recorded in the office of recorder of deeds in each judicial division in which real property of the testator is situated, within twenty days after letters are issued to him. An exemplification of the record of such a will, from any office where the same has been so recorded, either before or after this Code takes effect, may be in like manner recorded in the office of any recorder of deeds. Such a record or exemplification, or an exemplification of the record thereof, shall be received in evidence, as if the original will was produced and proved.
