N.Y. Lien Law § 84: Assignment of lien

§ 84. Assignment of lien. A lien, a notice of which has been filed

pursuant to the provisions of this article, may be assigned by a written

instrument duly acknowledged and filed in the same place where the

notice of the lien was filed. The assignment shall specify the debt upon

which the lien is founded, the date of the filing of the notice thereof

and the assignee. Such assignment and the name of the assignee shall be

entered by the clerk opposite the original entry of such lien, and after

the filing of such assignment, but not otherwise, the assignee may

enforce the lien in like manner as the assignor could have done.
