N.Y. Civil Practice Law & Rules § 1343: Notice of pendency; constructive notice

§ 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.
