N.Y. Civil Practice Law & Rules § 1344 – Filing, content and indexing of notice of pendency

1. Filing. In a case specified in section one thousand three hundred forty-three of this article the notice of pendency shall be filed in the office of the clerk of any county where property affected is situated, before or after service of a summons and at any time prior to judgment. Unless it has already been filed in that county, the complaint shall be filed with the notice of pendency.
2. Content, designation of index. A notice of pendency shall state the names of the parties to the action, that the action is for forfeiture pursuant to this article and a description of the property affected. A notice of pendency filed with a clerk who maintains a block index shall contain a designation of the number of each block on the land map of a county which is affected by the notice. A notice of pendency filed with a clerk who does not maintain a block index shall contain a designation of the names of each defendant against whom the notice is directed to be indexed.
3. Indexing. Each county clerk with whom a notice of pendency is filed shall immediately record and index it against the blocks or names designated. A county clerk who does not maintain a block index shall index a notice of pendency of an action for partition against the names of each claiming authority and each defendant not designated as wholly fictitious.
