Delaware law applies

By Jason Tenenbaum 8 min read

Key Takeaway

Delaware insurance law applied to NY court case involving out-of-state policy, accident location, and $15K coverage limits in no-fault claim dispute.

This article is part of our ongoing choice of law coverage, with 35 published articles analyzing choice of law issues across New York State. Attorney Jason Tenenbaum brings 24+ years of hands-on experience to this analysis, drawing from his work on more than 1,000 appeals, over 100,000 no-fault cases, and recovery of over $100 million for clients throughout Nassau County, Suffolk County, Queens, Brooklyn, Manhattan, and the Bronx.

In an increasingly mobile society, motor vehicle accidents frequently involve vehicles registered in one state, policies issued in another state, accidents occurring in yet another state, and medical treatment provided in still another state. These multi-state factual patterns raise complex choice of law questions in no-fault insurance litigation. When should New York courts apply New York’s comprehensive no-fault insurance regime, and when should they apply another state’s insurance laws that may provide different coverage limits, requirements, and procedures?

New York’s choice of law framework for insurance contracts follows established principles articulated in Auten v Auten and refined in subsequent Court of Appeals decisions. Courts employ a “grouping of contacts” approach, examining which state has the most significant relationship to the transaction and the parties. Relevant factors include where the policy was issued, where the insured resides, where the vehicle is principally garaged, where the accident occurred, and where the insured’s risks are centered.

The choice of applicable law can profoundly affect outcomes in no-fault cases. New York’s Insurance Law Section 5102 requires minimum first-party benefits of $50,000 per person for medical expenses, while other states mandate significantly lower minimums. Delaware, for instance, requires only $15,000 in medical expense coverage. When a healthcare provider treats an accident victim and submits substantial bills, whether New York or Delaware law applies can determine whether coverage exists for the entire claim or whether benefits have been exhausted.

Case Background

Flatbush Chiropractic, P.C. v GEICO Ins. Co., 2013 NY Slip Op 51104(U)(App. Term 2d Dept. 2013) presented this choice of law issue in a typical no-fault collection action. Flatbush Chiropractic provided medical treatment to an accident victim and submitted no-fault claims to GEICO Insurance Company. When GEICO failed to pay the submitted claims, the provider commenced litigation seeking to recover for the unpaid services.

GEICO moved for summary judgment dismissing the complaint, arguing that Delaware law applied to the insurance policy at issue. According to GEICO, the relevant policy was issued in Delaware to a Delaware resident for a vehicle registered in Delaware. The carrier submitted documentary evidence, including an NF-2 form signed by the plaintiff’s assignor, revealing that the accident itself had occurred in Delaware rather than New York.

Under Delaware’s statutory minimum coverage requirements, the policy provided only $15,000 in medical expense coverage per person. GEICO submitted affidavits from its claims and underwriting employees, along with documentary evidence, establishing that this $15,000 limit had been exhausted through payment of prior claims. Therefore, GEICO argued, no coverage remained for Flatbush Chiropractic’s bills regardless of their validity or reasonableness.

The provider opposed the motion, apparently arguing that New York law should apply because treatment was provided in New York and the litigation was pending in New York courts. The trial court granted GEICO’s motion, and the provider appealed to the Appellate Term.

Jason Tenenbaum’s Analysis

(1) Choice of Law

“Defendant sufficiently established that the relevant policy is a Delaware insurance policy, which was issued to a Delaware resident for an automobile registered in Delaware. Furthermore, the NF-2 form, which was signed by plaintiff’s assignor and proffered by defendant as an exhibit, revealed that the accident had occurred in Delaware. In view of Delaware’s significant contacts with the contract (see Matter of Eagle Ins. Co. v Singletary, 279 AD2d 56, 60 ), the application of Delaware law to the substantive issues is proper (see Matter of Allstate Ins. Co. [*2], 81 NY2d 219, 223 ; Auten v Auten, 308 NY 155, 160-161 ). Delaware law requires minimum compensation for, among other things, medical expenses in the amount of $15,000 for one person in any one accident”

(2) Prima facie case

“As defendant has made a prima facie showing, through the affidavits of its claims and underwriting employees, and through the submission of documentary evidence, that the policy had a $15,000 medical expenses coverage limit and that it had been exhausted (see New York and Presbyt. Hosp. v Allstate Ins. Co., 28 AD3d 528 ), defendant established its prima facie entitlement to judgment as a matter of law.”

The Appellate Term’s decision in Flatbush Chiropractic establishes a clear framework for choice of law analysis in multi-state no-fault cases. When the insurance policy was issued in another state, to a resident of that state, for a vehicle registered in that state, and the accident occurred in that state, New York courts will apply that state’s insurance laws even when treatment occurred in New York and litigation proceeds in New York courts.

This holding reflects the principle that insurance contracts are governed by the law of the state with the most significant relationship to the transaction. Delaware’s contacts with the policy overwhelmed New York’s interest in protecting healthcare providers treating patients within the state. The policy’s entire genesis and the insured risk centered in Delaware; only the fortuitous location of post-accident treatment created any New York connection.

The decision also establishes evidentiary standards for proving exhaustion of benefits under out-of-state policies. Insurance carriers can satisfy their prima facie burden through affidavits from claims and underwriting personnel with personal knowledge of the policy terms and payment history, coupled with documentary evidence such as policy declarations and claims payment records. Healthcare providers cannot defeat such proof through mere assertions that the carrier’s accounting is incorrect; they must produce contrary evidence.

Practical Implications

For healthcare providers treating accident victims, Flatbush Chiropractic underscores the importance of investigating coverage at the outset of treatment. Providers should not assume that New York’s generous minimum coverage applies to all patients treated in New York. When treating patients involved in out-of-state accidents or covered by out-of-state policies, providers should request copies of insurance declarations pages to verify applicable coverage limits.

Providers should also front-load treatment when limited coverage is identified. If a patient has only $15,000 in coverage rather than $50,000, that coverage may exhaust quickly, especially if multiple providers are treating the patient. Providers who delay treatment or spread it over extended periods risk finding that benefits have been exhausted by other providers’ claims by the time they submit their bills.

For insurance carriers, the decision provides a clear path to summary judgment when coverage has been exhausted under out-of-state policies. Carriers should document policy issuance, insured residence, vehicle registration, and accident location through admissible evidence. NF-2 forms, which accident victims complete and sign, are particularly valuable as they constitute admissions regarding accident location and circumstances.

Carriers should also maintain detailed claims payment histories that can support exhaustion defenses. Affidavits from claims personnel should specify the policy’s coverage limits, itemize all payments made, and demonstrate that the limits have been reached. Documentary backup, including explanations of benefits showing payments to other providers, strengthens the carrier’s case.

The decision also has broader implications for venue and forum selection in no-fault litigation. Healthcare providers might prefer to file in New York courts, assuming New York’s provider-friendly precedents and higher coverage minimums will apply. However, as Flatbush Chiropractic demonstrates, filing in New York does not guarantee application of New York law. When other states have stronger connections to the insurance contract, New York courts will apply those states’ laws even in suits filed in New York.

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.

Common Questions

Frequently Asked Questions

How do New York courts decide which state's law applies?

New York follows an 'interest analysis' approach to choice-of-law questions, examining which jurisdiction has the greatest interest in having its law applied. In insurance and personal injury cases, relevant factors include where the accident occurred, where the policy was issued, where the insured resides, and where the insurer is domiciled. Choice-of-law issues frequently arise in cross-border accidents and when out-of-state insurance policies cover New York accidents.

Understanding New York Choice of law Law

New York has a unique legal landscape that affects how choice of law 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 choice of law 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.

If you have questions about the legal issues discussed in this article, call (516) 750-0595 for a free, no-obligation consultation.

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.
