2006 New York Code - Sale In Parcels.

 
    §  153. Sale in parcels. On any such foreclosure, if any person having
  title to a part of the mortgaged premises, by conveyance from or through
  the mortgagor, delivers to the comptroller an affidavit stating that  he
  has such title, and describing with certainty such part, the comptroller
  on  the  sale  under  such foreclosure shall cause to be first sold that
  part of the mortgaged premises not specified in the  affidavit.  If  the
  part so sold does not produce enough to satisfy the amount so unpaid and
  costs  and expenses he shall immediately cause such part or parts of the
  premises as have been conveyed by the mortgagor  and  described  in  any
  such  affidavit,  to be sold, and if more than one part of such premises
  has been so conveyed, and an affidavit  made  as  herein  required,  the
  comptroller  shall  cause  such parts to be sold in the inverse order of
  the dates of  such  conveyances,  if  it  is  necessary  to  sell  them,
  commencing  with  the part last conveyed by the mortgagor, and such sale
  shall cease when the proceeds of the sale are sufficient to satisfy  the
  amount so unpaid and such costs and expenses.
