New York Laws
Part 4 - Rights of Third Parties
9-401 - Alienability of Debtor's Rights

(a) Other law governs alienability; exceptions. Except as otherwise
provided in subsection (b) and Sections 9--406, 9--407, 9--408, and
9--409, whether a debtor's rights in collateral may be voluntarily or
involuntarily transferred is governed by law other than this article.
(b) Agreement does not prevent transfer. An agreement between the
debtor and secured party which prohibits a transfer of the debtor's
rights in collateral or makes the transfer a default does not prevent
the transfer from taking effect.
