Assignment During Pending Litigation: A Valid Legal Strategy
In complex litigation involving mortgages, notes, and other financial instruments, parties often face questions about the timing of assignments. Can a chose in action or property interest be validly assigned after a lawsuit has already begun? This issue frequently arises in foreclosure cases and commercial disputes where standing not expressly pleaded becomes a central concern.
The New York courts have provided clear guidance on this matter, establishing that post-commencement assignments are not only permissible but can form the basis for proper plaintiff substitution. This principle is particularly important in today’s complex financial landscape, where mortgage notes and other instruments may change hands multiple times during the course of litigation.
Understanding the procedural requirements for such assignments is crucial for practitioners handling these cases, as proper documentation and court procedures must be followed to effectuate the change in real party in interest.
Jason Tenenbaum’s Analysis:
Citibank, N.A. v Van Brunt Props., LLC, 2012 NY Slip Op 03974 (2d Dept. 2012)
In the world of multiple assignments, it is sometimes asked whether you can assign a chose of action or an interest in something after the commencement of a lawsuit? The answer is “yes” and an order concomitantly amending the caption is also deemed proper:
“Finally, contrary to the defendant mortgagor’s contention, the documents submitted by the plaintiff established that the subject note and mortgage were validly assigned to Wells Fargo Bank, N.A., after the commencement of this action, and that Wells Fargo Bank, N.A., is therefore now the real plaintiff in interest. Under these circumstances, the Supreme Court should have granted the plaintiff’s motion to substitute Wells Fargo Bank, N.A., as the plaintiff in this action, and to amend the caption accordingly (see CPLR 1018, 3025; Deutsche Bank Trust Co., Americas v Stathakis, 90 AD3d 983; Maspeth Federal Savings and Loan Ass’n v Simon-Erdan, 67 AD3d 750, 751; East Coast Props. v Galang, 308 AD2d 431).”
Key Takeaway
Post-lawsuit assignments of notes and mortgages are legally valid and create grounds for plaintiff substitution. Courts must grant motions to substitute the assignee as the new plaintiff when proper documentation establishes the assignment occurred after litigation commenced, provided the procedural requirements under CPLR 1018 and 3025 are met.
Legal Update (February 2026): Since this 2012 post, CPLR provisions governing assignments and substitution of parties may have been amended, and appellate courts may have refined the procedural requirements for post-commencement assignments in foreclosure and commercial litigation. Practitioners should verify current CPLR 1018 requirements and recent case law developments regarding standing and assignment timing in ongoing litigation.

Legal Context
Why This Matters for Your Case
New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.
Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

Frequently Asked Questions
What is an assignment of benefits in no-fault insurance?
An assignment of benefits (AOB) is a document signed by the injured person transferring their right to receive no-fault insurance payments directly to a healthcare provider. This allows the provider to bill and collect from the insurer without the patient acting as intermediary.
Can an assignment of benefits be challenged?
Yes. Insurers frequently challenge the validity of assignments, arguing they were improperly executed, signed after treatment, or part of a fraudulent scheme. A defective or missing assignment can deprive the provider of standing to pursue benefits directly.
What makes an assignment of benefits valid in New York?
A valid AOB must be signed by the injured person, identify the provider, and be executed contemporaneously with or prior to treatment. It should be on the NF-AOB form or contain equivalent information. Courts scrutinize assignments carefully in no-fault litigation.
What does "standing" mean in a no-fault insurance case?
Standing refers to a party's legal right to bring a claim. In no-fault litigation, the medical provider must demonstrate a valid assignment of benefits from the patient to have standing to sue the insurer directly. Without a proper assignment, the provider lacks standing and the case may be dismissed.
How do assignment of benefits issues affect standing?
A medical provider typically obtains standing to pursue no-fault benefits through an assignment of benefits signed by the injured person. If the assignment is defective, incomplete, or missing, the insurer can challenge the provider's standing. Courts scrutinize assignment forms carefully, and defects can be fatal to the claim.
