Section 58Republic Act No. 26 insofar as not inconsistent with this Decree. The procedure relative to administrative reconstitution of lost or destroyed certificate prescribed in said Act is hereby abrogated., Sec./Art. 58

Procedure where conveyance involves portion of land. If a deed or conveyance is for a part only of the land described in a certificate of title, the Register of Deeds shall not enter any transfer certificate to the grantee until a plan of such land showing all the portions or lots into which it has been subdivided and the corresponding technical descriptions shall have been verified and approved pursuant to Section 50 of this Decree.

Meanwhile, such deed may only be annotated by way of memorandum upon the grantor's certificate of title, original and duplicate, said memorandum to serve as a notice to third persons of the fact that certain unsegregated portion of the land described therein has been conveyed, and every certificate with such memorandum shall be effectual for the purpose of showing the grantee's title to the portion conveyed to him, pending the actual issuance of the corresponding certificate in his name.

Upon the approval of the plan and technical descriptions, the original of the plan, together with a certified copy of the technical descriptions shall be filed with the Register of Deeds for annotation in the corresponding certificate of title and thereupon said officer shall issue a new certificate of title to the grantee for the portion conveyed, and at the same time cancel the grantor's certificate partially with respect only to said portion conveyed, or, if the grantor so desires, his certificate may be canceled totally and a new one issued to him describing therein the remaining portion: Provided, however, that pending approval of said plan, no further registration or annotation of any subsequent deed or other voluntary instrument involving the unsegregated portion conveyed shall be effected by the Register of Deeds, except where such unsegregated portion was purchased from the Government or any of its instrumentalities.

If the land has been subdivided into several lots, designated by numbers or letters, the Register of Deeds may, if desired by the grantor, instead of canceling the latter's certificate and issuing a new one to the same for the remaining unconveyed lots, enter on said certificate and on its owner's duplicate a memorandum of such deed of conveyance and of the issuance of the transfer certificate to the grantee for the lot or lots thus conveyed, and that the grantor's certificate is canceled as to such lot or lots.
