Title Examination Standards

Chapter 24. Mortgages and Other Liens
§ 24.3.2 Assignment of Corrective or Re-Recorded Instruments Evidencing Liens or Encumbrances
Each instrument of record evidencing a lien or encumbrance must be described in an assignment thereof, except when an instrument acknowledging a lien or encumbrance appears followed by a similar instrument in which it is stated on the face of the instrument that the latter instrument is given to correct some defect in the former instrument, or when it appears on the face of the latter instrument that it is merely a re-recording of the former instrument. Specifically, where the latter instrument shows it evidences the identical lien or encumbrance as the former instrument, an assignment of either the latter or former instrument, which does not specifically describe the other, is sufficient to assign said lien or encumbrance.
The 2002 Report of the Title Examination Standards Committee proposed this standard. 73 O.B.J. 3004 (10/26/2002). the Real Property Law Section approved, November 21, 2002, and the House of Delegates adopted it November 22, 2002.
