In New York no-fault insurance disputes, contractual arbitration serves as the primary method for resolving claims between healthcare providers and insurance carriers. When a provider seeks to arbitrate unpaid claims, the insurance carrier has limited time to challenge the arbitrability of the dispute. CPLR 7503(c) establishes a strict 20-day deadline for objecting to arbitration, and courts enforce this deadline with remarkable rigidity.

The 20-day rule reflects a fundamental policy choice favoring arbitration as an efficient alternative to litigation. Once an insurance policy contains an arbitration clause, and a party serves proper notice of intention to arbitrate, the respondent must act quickly or forever waive objections to arbitrability. This bright-line rule promotes finality and prevents parties from delaying arbitration proceedings through belated challenges.

However, the enforceability of the 20-day deadline depends on the adequacy of the notice of intention to arbitrate. CPLR 7503(c) prescribes specific content requirements for arbitration notices, including identification of the agreement to arbitrate, the controversy to be arbitrated, and a demand that the dispute proceed to arbitration. Only a notice that complies with these statutory requirements triggers the 20-day clock. Defective notices do not start the limitations period running.

Case Background

Matter of Ameriprise Ins. Co. v Sandy, 2018 NY Slip Op 00828 (2d Dept. 2018) arose from a no-fault insurance dispute in which a healthcare provider served Ameriprise Insurance Company with a notice of intention to arbitrate on November 2, 2015. The notice identified unpaid medical claims that the provider sought to resolve through arbitration under the insurance policy’s arbitration provision.

Rather than responding within 20 days, Ameriprise waited and later commenced a CPLR Article 75 proceeding seeking to stay the arbitration. The insurance carrier argued that the dispute was not arbitrable for various reasons, including contentions that the notice was defective or deceptive in some manner. Ameriprise contended that the notice’s alleged defects excused its failure to respond within the statutory deadline.

The provider opposed the stay application, arguing that Ameriprise had waived all objections to arbitrability by failing to move within 20 days of receiving the November 2, 2015 notice. The lower court sided with the provider, and Ameriprise appealed to the Second Department.

Jason Tenenbaum’s Analysis

“Where an insurance policy contains an agreement to arbitrate, CPLR 7503 (c) requires a party, once served with a , to move to stay such arbitration within 20 days of service of such , else he or she is precluded from objecting’” (Matter of Government Empls. Ins. Co. v Castillo-Gomez, 34 AD3d 477, 478, quoting Matter of Steck , 89 NY2d 1082, 1084). Here, the proceeding was not commenced within 20 days of the receipt of the November 2, 2015, notice of intention to arbitrate.

In order for the 20-day limitation period to be enforceable, the notice of intention to arbitrate must comply with the requirements of CPLR 7503(c) (see Government Empls. Ins. Co. v Castillo-Gomez, 34 AD3d at 478; Matter of Nassau Ins. Co. , 100 AD2d 969, 970; State Farm Mut. Auto. Ins. Co. v Szwec, 36 AD2d 863, 863). Here, contrary to Ameriprise’s contention, the November 2, 2015, notice complied with all the statutory requirements.

Ameriprise failed to establish that the November 2, 2015, notice of intention to arbitrate was deceptive and intended to prevent it from timely contesting the issue of arbitrability ”

I think Ameriprise wants the legal fees the expended back.

The Second Department’s decision in Ameriprise underscores the unforgiving nature of the 20-day rule under CPLR 7503(c). Once a party receives a statutorily compliant notice of intention to arbitrate, the 20-day clock begins running immediately. There are no extensions for weekends, holidays, or good cause. The party must either file an Article 75 proceeding to stay arbitration within those 20 days or accept that the dispute will proceed to arbitration without judicial intervention.

The court’s analysis also addresses a common defense strategy: attacking the adequacy of the arbitration notice itself. Insurance carriers facing unwanted arbitration frequently argue that the notice was defective, deceptive, or otherwise noncompliant with CPLR 7503(c). If successful, such arguments would mean the 20-day clock never started running, thereby excusing the carrier’s delayed objection.

However, Ameriprise demonstrates that courts scrutinize these arguments skeptically. The decision requires carriers to establish that the notice actually failed to comply with statutory requirements or was intentionally deceptive to prevent timely objection. Mere disagreement with the notice’s characterization of the dispute, or strategic dissatisfaction with being forced into arbitration, does not render the notice defective.

Practical Implications

For insurance carriers, Ameriprise provides a critical practice reminder: calendar management is everything in arbitration disputes. When an arbitration notice arrives, carriers must immediately assess whether they wish to contest arbitrability. This assessment should occur within days, not weeks, to allow time for preparing and filing an Article 75 proceeding if needed.

Carriers should establish internal procedures ensuring that arbitration notices receive immediate attention. These procedures might include flags in document management systems, automatic calendaring of the 20-day deadline when an arbitration notice is logged, and expedited review protocols for evaluating whether to challenge arbitration. Missing the 20-day deadline can result in being forced into arbitration even when strong grounds exist to challenge arbitrability.

For healthcare providers initiating arbitration, the decision confirms the importance of preparing notices that strictly comply with CPLR 7503(c). Providers should use form notices that track the statutory language, clearly identify the arbitration agreement, specify the claims in dispute, and demand arbitration. Defective notices give carriers an escape hatch from the 20-day rule.

Providers should also document service of arbitration notices carefully. Affidavits of service should be prepared contemporaneously and retained in the file. When carriers later claim they never received notice or received defective notice, contemporaneous proof of proper service can defeat those arguments.

The decision also highlights the costs of procedural mistakes in insurance litigation. As counsel observes, Ameriprise likely incurred substantial legal fees preparing and prosecuting the Article 75 proceeding, only to have the matter dismissed for untimeliness. Those fees, which might have been avoided through proper calendar management, represent an entirely preventable loss.

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.

Article 75 Proceedings: Judicial Review of Arbitration

CPLR Article 75 governs the judicial review of arbitration awards in New York. In no-fault practice, Article 75 petitions are the mechanism for challenging master arbitration awards — whether on grounds of irrationality, excess of power, or procedural irregularity. The standards for vacating or confirming arbitration awards are narrow but important. These articles analyze Article 75 jurisprudence and the practical considerations involved in seeking judicial review of no-fault arbitration outcomes.

Frequently Asked Questions

What is CPLR Article 75?

CPLR Article 75 governs arbitration in New York, including the procedures for confirming, vacating, and modifying arbitration awards. In no-fault practice, Article 75 is used to convert arbitration awards into enforceable court judgments. A petition to confirm or vacate an arbitration award must be filed within one year of the award being delivered (CPLR 7510). Courts can vacate awards on narrow grounds, including corruption, fraud, arbitrator misconduct, or the arbitrator exceeding their power.

Understanding New York Article 75 Law

New York has a unique legal landscape that affects how article 75 cases are litigated and resolved. The state's court system includes the Civil Court (for claims up to $25,000), the Supreme Court (the primary trial court for unlimited jurisdiction), the Appellate Term (which hears appeals from lower courts), the Appellate Division (divided into four Departments, with the Second Department covering Long Island, Brooklyn, Queens, Staten Island, and several upstate counties), and the Court of Appeals (the state's highest court). Each court has its own procedural requirements, local rules, and case-assignment practices that can significantly impact the outcome of your case.

For article 75 matters on Long Island, cases are typically filed in Nassau County Supreme Court (at the courthouse in Mineola) or Suffolk County Supreme Court (in Riverhead). No-fault arbitrations are heard through the American Arbitration Association, which assigns arbitrators throughout the metropolitan area. Workers' compensation claims go to the Workers' Compensation Board, with hearings at district offices across the state. Understanding which forum is appropriate for your case — and the specific procedural rules that apply — is essential for a successful outcome.

The procedural landscape in New York also includes important timing requirements that can affect your case. Most civil actions are subject to statutes of limitations ranging from one year (for intentional torts and claims against municipalities) to six years (for contract actions). Personal injury cases generally have a three-year deadline under CPLR 214(5), while medical malpractice claims must be filed within two and a half years under CPLR 214-a. No-fault insurance claims have their own regulatory deadlines, including 30-day filing requirements for applications and 45-day deadlines for provider claims. Understanding and complying with these deadlines is critical — missing a filing deadline can permanently bar your claim, regardless of how strong your case may be on the merits.

Attorney Jason Tenenbaum regularly practices in all of these venues. His office at 326 Walt Whitman Road, Suite C, Huntington Station, NY 11746, is centrally located on Long Island, providing convenient access to courts and offices throughout Nassau County, Suffolk County, and New York City.

New York's substantive law also presents distinct challenges. In motor vehicle cases, the no-fault system under Insurance Law Article 51 provides first-party benefits regardless of fault, but limits the right to sue for non-economic damages unless the plaintiff establishes a "serious injury" under one of nine statutory categories. This threshold — codified at Insurance Law Section 5102(d) — requires medical evidence showing more than a minor or subjective injury, and courts have developed detailed standards for each category. Fractures must be documented through imaging studies. Claims of permanent consequential limitation or significant limitation of use require quantified range-of-motion testing with comparison to norms. The 90/180-day category demands proof that the plaintiff was unable to perform substantially all of their usual daily activities for at least 90 of the 180 days following the accident.

In employment discrimination cases, the legal standards vary depending on whether the claim arises under state or local law. The New York State Human Rights Law employs a burden-shifting framework: the plaintiff must first establish a prima facie case by showing membership in a protected class, qualification for the position, an adverse employment action, and circumstances giving rise to an inference of discrimination. The burden then shifts to the employer to articulate a legitimate, non-discriminatory reason for its decision. If the employer meets this burden, the plaintiff must demonstrate that the stated reason is pretextual. The New York City Human Rights Law, by contrast, applies a broader standard, asking whether the plaintiff was treated less well than other employees because of a protected characteristic.
