N.Y. Real Property Law § 324: Effect of recording assignment of mortgage

§ 324. Effect of recording assignment of mortgage. The recording of an

assignment of a mortgage is not in itself a notice of such assignment to

a mortgagor, his heirs or personal representatives, or to an owner of

the mortgaged premises where such assignment is recorded subsequent to

the recording of the conveyance of such premises to such owner, so as to

invalidate a payment made by either of them to the mortgagee or to a

prior assignee of the mortgage.
