Relation-Back Saves Insurer Subrogation Intervention and Procedural Defects May Be Cured in Reply: Steward v. Brooklyn Pier 1 Residential Owner, LP

1. Introduction

Steward v Brooklyn Pier 1 Residential Owner, LP (2026 NY Slip Op 00933 [2d Dept Feb. 18, 2026]) addresses when an insurer that has paid supplementary uninsured/underinsured motorists (SUM) benefits may intervene in its insured’s ongoing personal-injury action to assert subrogation, despite a limitations defense and despite initial noncompliance with the procedural requirement to attach a proposed pleading.

The plaintiff, Levern T. Steward, was struck by a vehicle at a construction site. He sued multiple owner/contractor defendants in 2019. Separately, after arbitration, he obtained a $775,000 SUM award from his employer’s insurer, nonparty Utica Mutual Assurance Company (“Utica”). In April 2022, Utica moved to intervene in the personal-injury action to assert a subrogation cause of action seeking reimbursement from allegedly responsible third parties. The Supreme Court, Kings County denied intervention; Utica appealed.

The key issues on appeal were (i) whether Utica’s subrogation claim was time-barred or salvaged by the relation-back doctrine, and (ii) whether intervention should be granted notwithstanding that Utica did not attach a proposed pleading to its initial motion papers.

2. Summary of the Opinion

The Appellate Division, Second Department reversed and granted Utica’s motion to intervene. It held:

  • Utica’s subrogation cause of action was timely under the relation-back doctrine codified in CPLR 203(c), because it arose from the same occurrence as the plaintiff’s claims and the defendants were on notice that the litigation concerned liability for the accident underlying the insurer’s reimbursement claim.
  • Intervention was warranted because Utica had a “real and substantial interest” in the outcome, shared common questions of law and fact with the main action, could be bound by the judgment, and its interests were not otherwise represented.
  • Although CPLR 1014 requires a motion to intervene to be accompanied by a proposed pleading, Utica’s initial failure was cured when it annexed the proposed complaint to its reply papers, and the defect could be disregarded or corrected under CPLR 2001 because no substantial right was prejudiced.

3. Analysis

3.1. Precedents Cited

(a) Limitations period and relation-back

  • Ruiz v Sanchez, 219 AD3d 1363, 1363: Cited for the baseline rule that personal-injury actions are generally governed by a three-year statute of limitations (CPLR 214[5]). The court used it as the starting point before turning to relation-back as the saving doctrine.
  • Matter of Greater N.Y. Health Care Facilities Assn. v DeBuono, 91 NY2d 716, 721: Quoted for the modern statement of relation-back principles and the proposition that relation-back analysis applies broadly (including beyond classic pleadings contexts). The Second Department relied on its two-part framework: (1) same “transaction or occurrence,” and (2) a relationship close enough that the original pleading gave notice of the intervenor’s “specific claim” so that no prejudice results.
  • McHale v Anthony, 41 AD3d 265, 266: Used to support the conclusion that where the intervenor’s claim is sufficiently similar to the original claims arising from the same event, defendants are deemed on notice and relation-back is appropriate.

(b) Standards for intervention (as of right and discretionary)

  • Phoenix Life Ins. Co. v Jacob P Ilit A, 177 AD3d 1008, 1008: Cited for intervention as of right under CPLR 1012(a)(3) and for reiterating that the motion must be accompanied by a proposed pleading (CPLR 1014).
  • Atlantic Ave. Capital, LLC v 980 Atl. Holdings, LLC, 231 AD3d 692, 694: Cited for intervention as of right under CPLR 1012(a)(2) when representation “is or may be inadequate” and the person “is or may be bound by the judgment.”
  • Wells Fargo Bank, N.A. v Mazzara, 124 AD3d 875, 875-876: Cited for intervention under CPLR 1012(a)(2) and for the prejudice/delay considerations that also inform discretionary intervention analysis.
  • Al-Rowmeim v Alazwear, 233 AD3d 640, 641-642 and Matter of Sclafani Petroleum, Inc., 173 AD3d 1042, 1043: Cited for discretionary intervention under CPLR 1013 where the intervenor’s claim shares common questions of law or fact with the main action.
  • Global Team Vernon, LLC v Vernon Realty Holding, LLC, 93 AD3d 819, 820 and Wells Fargo Bank, N.A. v McLean, 70 AD3d 676, 677: Cited for the practical principle that whether intervention is “of right” (CPLR 1012) or “discretionary” (CPLR 1013) often matters less than whether the intervenor has a “real and substantial interest” in the outcome—an interest Utica plainly had as the payer seeking reimbursement.
  • Deutsche Bank Natl. Trust Co. v Sharrow, 232 AD3d 767, 769: Cited for the CPLR 1013 directive that courts consider whether intervention will unduly delay the action or prejudice substantial rights.

(c) The proposed pleading requirement and curable defects

  • Matter of Merestead, 188 AD3d 690, 691 and Phoenix Life Ins. Co. v Jacob P Ilit A, 177 AD3d at 1008: Cited for the procedural requirement of CPLR 1014: a motion to intervene “shall be accompanied by a proposed pleading.”
  • CPLR 2001 and Tenenbaum v Ziv, 231 AD3d 1181, 1182: Used to justify excusing/correcting a procedural irregularity where no substantial right is prejudiced; here, the missing proposed pleading was supplied with reply papers.
  • Landa v Poloncarz, 215 AD3d 739, 741 (cited with “cf.”): Invoked as a contrasting reference point, signaling that not every failure to comply with CPLR 1014 will be excused—particularly where the defect is not cured, or where prejudice or inadequate notice results.

(d) Subrogation doctrine (insurer “stands in the shoes”)

  • Blue Cross & Blue Shield of N.J., Inc. v Philip Morris USA Inc., 3 NY3d 200, 206 and Winkelmann v Excelsior Ins. Co., 85 NY2d 577, 581: Cited for the foundational definition of subrogation—after paying a covered loss, the insurer is placed in the position of its insured to seek recovery from the responsible third party.
  • Utica Mut. Ins. Co. v Brooklyn Navy Yard Dev. Corp., 52 AD3d 821, 822 and North Star Reins. Corp. v Continental Ins. Co., 82 NY2d 281, 294: Cited for the equitable nature of subrogation and the “stand in the shoes” framework: the insurer may pursue third parties whose wrongdoing caused the loss paid.
  • Humbach v Goldstein, 229 AD2d 64, 67 and Federal Ins. Co. v Arthur Andersen & Co., 75 NY2d 366, 372: Cited for the limiting principle that a subrogee’s rights are no greater than the insured’s; the insurer’s claim is subject to defenses that could have been asserted against the insured.

3.2. Legal Reasoning

(a) Relation-back makes Utica’s subrogation claim timely

The court treated the case as a classic application of CPLR 203(c): Utica’s proposed subrogation claim was “based on the same transaction or occurrence” as the plaintiff’s tort claims (the construction-site accident), and it did not inject a new liability theory so much as seek reimbursement for payments made because of that same occurrence.

Critically, the decision emphasizes notice and lack of prejudice. Because the plaintiff’s complaint already put defendants on notice that liability for the accident would be litigated, the insurer’s “mirrors, in all respects” subrogation pleading did not surprise defendants with a fundamentally different case. That “similar enough” alignment satisfied the notice component described in Matter of Greater N.Y. Health Care Facilities Assn. v DeBuono.

(b) Intervention should be granted where the insurer’s interest is real, substantial, and unrepresented

The Second Department synthesized CPLR 1012 and 1013 through the lens of the “real and substantial interest” cases (Global Team Vernon, LLC v Vernon Realty Holding, LLC; Wells Fargo Bank, N.A. v McLean). Subrogation gave Utica a direct economic stake in the litigation’s outcome: if defendants were found liable and damages awarded, Utica could pursue reimbursement; if the action failed, Utica’s recovery path would be impaired.

The court also stressed binding effect and inadequacy of representation: Utica “would be bound by the judgment” and, without being a party, its specific reimbursement interest would not be litigated or protected. This aligned with CPLR 1012(a)(2) principles as articulated in Atlantic Ave. Capital, LLC v 980 Atl. Holdings, LLC.

(c) No undue delay or prejudice

Applying CPLR 1013 and Deutsche Bank Natl. Trust Co. v Sharrow, the court found intervention would not unduly delay the case or prejudice substantial rights. The insurer’s pleading was duplicative of the plaintiff’s liability allegations, and the court accepted Utica’s position that no additional discovery or motion practice was required. The court therefore treated intervention as largely administrative—adding a party to assert a derivative claim, not reshaping the litigation.

(d) CPLR 1014 compliance can be cured via reply where no substantial right is harmed

Utica initially failed to attach a proposed complaint (CPLR 1014). The Second Department nevertheless held the Supreme Court “improvidently exercised its discretion” by denying intervention because Utica later annexed the proposed complaint to its reply, and the defect was curable under CPLR 2001 (as supported by Tenenbaum v Ziv).

The practical rule that emerges is not that CPLR 1014 is optional, but that courts may forgive initial noncompliance when the intervenor promptly supplies the missing pleading, and where the opposing parties suffer no meaningful notice-based or procedural prejudice (with Landa v Poloncarz flagged as a contrast where such forgiveness may be inappropriate).

3.3. Impact

  • Insurer subrogation intervention is strongly favored when derivative and non-disruptive. The decision reinforces that when an insurer’s subrogation pleading “mirrors” the insured’s complaint and turns on the same liability questions, intervention is likely, especially where the insurer has already paid (or been compelled to pay) benefits and faces being functionally affected by the outcome.
  • Relation-back doctrine is affirmed as a key limitations tool for intervening subrogees. Insurers commonly pay benefits after a tort action is filed; this case underscores that an intervening subrogation claim may relate back to the insured’s timely filing, preventing the statute of limitations from defeating reimbursement where notice and identity-of-occurrence are present.
  • Procedural flexibility under CPLR 2001 is highlighted. Litigants moving to intervene should still comply with CPLR 1014, but Steward signals that a curable omission (like a missing proposed pleading) will not automatically defeat intervention if cured quickly and without prejudice.
  • Defendants should anticipate insurer participation after SUM payments. In construction-site and motor-vehicle-adjacent injury cases, defendants can expect that a SUM carrier paying a substantial award may seek to enter the tort action. Defense strategy should account for the insurer as an aligned-but-distinct plaintiff with reimbursement priorities and settlement positioning.

4. Complex Concepts Simplified

  • Supplementary uninsured/underinsured motorists (SUM) benefits: Insurance coverage that pays an injured person when the at-fault driver has no insurance or not enough insurance. Here, Utica paid SUM benefits after arbitration.
  • Subrogation: After paying its insured, the insurer can pursue the responsible third party to recoup what it paid. The insurer “stands in the shoes” of the insured, meaning it has no greater rights than the insured and faces the same defenses (Humbach v Goldstein; Federal Ins. Co. v Arthur Andersen & Co.).
  • Intervention: A procedure allowing a nonparty to become a party to protect its interests. It can be “as of right” (CPLR 1012) or discretionary (CPLR 1013), but courts focus on whether the intervenor has a “real and substantial interest” and whether intervention causes delay or prejudice.
  • Relation-back doctrine (CPLR 203[c]): A rule allowing an otherwise late claim to be treated as filed on the earlier date of a timely pleading, when the claims arise from the same event and the original pleading gave defendants fair notice so they are not prejudiced.
  • CPLR 1014 proposed pleading requirement and CPLR 2001: A motion to intervene should include the would-be intervenor’s proposed complaint/answer (CPLR 1014). CPLR 2001 permits courts to correct or disregard certain mistakes if no substantial right is harmed—here, allowing the proposed complaint to be supplied with reply papers.

5. Conclusion

Steward v Brooklyn Pier 1 Residential Owner, LP clarifies and strengthens a practical pathway for insurers that have paid SUM benefits to protect their reimbursement rights: intervene in the insured’s pending tort action and rely on relation-back where the subrogation claim arises from the same occurrence and defendants had notice through the original complaint. The decision also underscores a pragmatic, nonformalistic approach to intervention procedure—permitting cure of a missing proposed pleading via reply under CPLR 2001 where no prejudice is shown.
