Section 58
SEC. 58. When a deed, in fee is for a part only of the land described in a certificate of title, the register of deeds shall also enter a new certificate and issue an owner's duplicate to the grantor for the part of the land not included in the deed. In every case of transfer the new certificate or certificates shall include all the land described in the original and surrendered certificates: Provided, however, That no new certificate to a grantee of a part only of the land shall be invalid by reason of the failure of the register of deeds to enter a new certificate to the grantor for the remaining unconveyed portion: And provided further, That in case the land described in a certificate of title is divided into lots, designated by numbers or letters, with measurements of all the bounds, and a plan of said land has been filed with the clerk and verified pursuant to section forty-four of this Act, and a certified copy thereof is recorded in the registration book with the original certificate, when the original owner makes a deed of transfer in fee of one or more of such lots, the register of deeds may, instead of canceling such certificate and entering a new certificate to the grantor for the part of the land not included in the deed of transfer, enter on the original certificate and on the owner's duplicate certificate a memorandum of such deed of transfer, with a reference to the lot or lots thereby conveyed as designated on such plan, and that the certificate is canceled as to such lot or lots; and every certificate with such memorandum shall be effectual for the purpose of showing the grantor's title to the remainder of the land not conveyed as if the old certificate had been canceled and a new certificate of such land had been entered; and such process may be repeated so long as there is convenient space upon the original certificate and the owner's duplicate certificate for making such memorandum of sale of lots.
