Delta Diagnostic Radiology, P.C. v Country-Wide Ins. Co., 2018 NY Slip Op 50118(U)(App. Term 2d Dept. 2018)
No-fault statutory prejudgment interest accrues upon overdue first-party no-fault benefits at the rate of two percent per month “unless the applicant unreasonably delays the … court proceeding” (11 NYCRR 65-3.9 , ). While the court found that plaintiff was not entitled to the interest which had accrued between the commencement of the action on March 30, 2006 and the date plaintiff filed the notice of trial, May 30, 2013, plaintiff’s argument that the toll upon the accrual of interest should not begin until January 28, 2008, as plaintiff had not unreasonably delayed prosecution of the action prior to that date, is correct. Motions were made and discovery demands were served during the period between the commencement of the action and December 27, 2007, the date plaintiff served its second demand for interrogatories. Consequently, a motion by plaintiff to compel defendant to respond to the demand for interrogatories would have been premature prior to January 28, 2008 (see CPLR 2103 ; 3133 ; General Construction Law § 25-a). As a result, plaintiff is entitled to no-fault statutory prejudgment interest from the commencement of the action on March 30, 2006 through January 27, 2008.

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 statutory interest applies to overdue no-fault claims?
Under 11 NYCRR §65-3.9, overdue no-fault claims accrue interest at 2% per month from the date the claim became overdue. A claim is overdue if not paid or denied within 30 days of the insurer receiving proof of claim. This interest is a powerful incentive for prompt processing.
When does interest begin to accrue on a no-fault claim?
Interest begins on the 31st day after the insurer receives all requested verification (or the date verification was due if the insurer failed to request it timely). If the insurer fails to pay or deny within 30 days, 2% monthly interest accrues automatically until payment.
Can the insurer avoid paying interest on late no-fault claims?
Only if the insurer can demonstrate a valid excuse for the delay — such as a pending verification request that was timely issued. If the insurer caused the delay through untimely processing or late denials, interest is mandatory and cannot be waived.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
