2006 New York Code - Effect Of Conveyance Where Property Is Leased.

 
    § 248. Effect of conveyance where property is leased. An attornment to
  a  grantee  is  not  requisite  to  the validity of a conveyance of real
  property occupied by a tenant, or of the rents or  profits  thereof,  or
  any other interest therein. But the payment of rent to a grantor, by his
  tenant,  before  notice  of  the  conveyance, binds the grantee; and the
  tenant is not liable to such grantee, before such notice, for the breach
  of any condition of the lease.
