A.    Each deed, instrument or writing by which lands, tenements, or other realty is sold, granted, assigned, transferred or otherwise conveyed shall have noted upon it the tax roll parcel number. The number shall be used only for administrative and procedural purposes and shall not be proof of title and in the event of any conflicts, the stated legal description noted upon the documents shall govern.

    B.    The validity of any document described in subsection A of this section shall not be affected if the tax roll parcel number noted thereon is erroneous or omitted, and there shall be no liability attaching to any person for an error in such number or for omission of such number.

    C.    If the document describes a parcel which has been created by the division of an existing parcel and which at the time of the recording has not been given a separate parcel number, the document shall have noted upon it the words “portion of” and the parcel number of the parcel from which it was created.

    D.    The recorder shall not record any deed, instrument or writing subject to the provisions of this section unless the document has noted upon it the tax roll parcel number. (Prior gen. code § 2-29.04)
