Section 1343. Notice of pendency; constructive notice

A notice of pendency
  may be filed in any action brought pursuant to this article in which the
  judgment demanded would affect the title to, or the possession,  use  or
  enjoyment  of,  real  property.  The  pendency  of  such  an  action  is
  constructive notice, from the time of filing of the notice  only,  to  a
  purchaser from, or incumbrancer against, any defendant named in a notice
  of  pendency  indexed in a block index against a block in which property
  affected is situated or any defendant against whose  name  a  notice  of
  pendency  is  indexed.  A  person  whose  conveyance  or  incumbrance is
  recorded after the filing of the notice  is  bound  by  all  proceedings
  taken in the action after such filing to the same extent as if he or she
  were a party.
