Section 18
SEC. 18. In case a certificate of title, considered lost or destroyed, be found or recovered, the same shall prevail over the reconstituted certificate of title, and, if both titles appear in the name of the same registered owner, all memoranda of new liens or encumbrances, if any, made on the latter, after its reconstitution, except the memorandum of the reservation referred to in section seven of this Act, shall be transferred to the recovered certificate of title. Thereupon, the register of deeds shall cancel the reconstituted certificate of title and spread upon the owner's duplicate, as well as on the co-owner's, mortgagee's or lessee's duplicate, if any has been issued, such annotations of subsisting liens or encumbrances as may appear on the recovered certificate of title, canceling at the same time the memorandum of the reservation referred to in section seven hereof: Provided, however, That if the reconstituted certificate of title has been cancelled by virtue of any deed or instrument, whether voluntary or involuntary, or by an order of the court, and a new certificate of title has been issued, the recovered certificate of title shall be likewise cancelled, but all subsisting liens or encumbrances, if any, appearing thereon shall be transferred to the new certificate of title and to its owner's duplicate, as well as to any co-owner's, mortgagee's or lessee's duplicate that may have been issued, the memorandum of the reservation referred to in section seven of this Act, if any, being thereby ipso facto cancelled.
