N.Y. Real Property Actions & Proceedings Law § 637: Action against one defendant subject to rights of others

§ 637. Action against one defendant subject to rights of others.

Where one or more answering defendants hold under another defendant, and

the plaintiff elects to proceed against the latter, subject to the

rights and interests of the former, if the plaintiff recovers final

judgment against the defendant under whom they hold, the judgment

operates as a transfer to the plaintiff of that defendant's right, title

and interest.
