At first, the Appellate Term said it was a fatal defect. Then, they said it was a waivable defect. After that it was held to be a defect that literally could cured nunc pro tunc through filing a new affidavit with the Civil Court clerk. Now, it is deemed irrelevant. Such is the sordid history of this provision of the CPLR. What is noteworthy is that Second Department in 2014 for the first time I can remember held this to defect to be fatal.
Flatlands Med., P.C. v AAA Ins., 2014 NY Slip Op 24048 (App.. Term 2d Dept. 2014)
“At the outset, we note that, despite defendant’s failure to submit a proper certificate of conformity together with the out-of-state affidavit of its corporate officer, as required by CPLR 2309 (c), this omission was not a fatal error (see CPLR 2001;Gonzalez v Perkan Concrete Corp., 110 AD3d 955 ; Mack-Cali Realty, L.P. v Everfoam Insulation Sys., Inc., 110 AD3d 680 ; Fredette v Town of Southampton, 95 AD3d 940 ; Bay Med. P.C. v GEICO Ins. Co., ___ Misc 3d ___, 2013 NY Slip Op 52084 ) and, therefore, the affidavit has been reviewed on this appeal. In view of the foregoing, we find that the Civil Court properly granted defendant leave to renew and reargue its motion for summary judgment.
See: Freedom Mtge. Corp. v Toro, 113 AD3d 815 (2d Dept. 2014)
“It appears from this record that the plaintiff was the holder of the mortgage and note. In any event, by failing to appear in the action, the debtor waived the defense of lack of standing (see HSBC Bank USA, N.A. v Taher, 104 AD3d 815, 817 ). However, the affidavit attesting to the debtor’s default in repaying the mortgage loan did not comply with CPLR 2309 (c). Under the circumstances of this case, the Supreme Court did not improvidently exercise its discretion in denying relief to the movant without prejudice.”
Justice Solomon (who wrote the underlying Supreme court deicison) was in the App. Term panel)
As to the merits, the court held as follows:
“defendant demonstrated, prima facie, through documentary evidence, that it was not authorized to conduct an insurance business in New York and, as a result, jurisdiction could not be obtained over it pursuant to Insurance Law § 1212. Furthermore, defendant established, prima facie, through the affidavit of its corporate officer, that neither it nor its reciprocal insurers, affiliates, or subsidiaries provide, write, or sell insurance in the State of New York or to its residents. They do not provide goods or services within New York nor do they transact business in New York and they do not have any offices or agents in this state. Thus, defendant did not perform any of the acts specified in Insurance Law § 1213 (b) (1) in New York and, as a result, jurisdiction could not be obtained over it pursuant to Insurance Law § 1213 (see Farm Family Mut. Ins. Co. v Nass, 121 AD2d 498 ).”
On this type of motion, this is what the affidavit has to state in order to shift the burden back to the medical provider/injured party.

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.

CPLR 2106 and 2309: Affirmation & Oath Requirements
CPLR 2106 governs who may submit an affirmation in lieu of an affidavit in New York courts, while CPLR 2309 addresses the requirements for oaths, affidavits, and the certification of out-of-state documents. These seemingly technical provisions have significant practical impact — an improperly executed affirmation or affidavit can render an entire summary judgment motion defective.

Frequently Asked Questions
What is the difference between a CPLR 2106 affirmation and a CPLR 2309 affidavit?
A CPLR 2106 affirmation can be signed by an attorney, physician, dentist, or podiatrist without notarization — the affirmant simply affirms under penalty of perjury. A CPLR 2309 affidavit requires a notary public or authorized officer to administer an oath. Using the wrong form can result in a court rejecting the submission.
When must I use a notarized affidavit versus an affirmation in New York?
Licensed attorneys, physicians, dentists, and podiatrists may use unsworn affirmations under CPLR 2106. All other individuals must use notarized affidavits under CPLR 2309. In no-fault litigation, this distinction frequently arises when submitting medical evidence or opposing summary judgment motions.
Can a court reject evidence submitted in the wrong format?
Yes. Courts routinely reject affidavits and affirmations that do not comply with CPLR 2106 or 2309. An improperly sworn document may be treated as a nullity, which can be fatal to a motion for summary judgment or opposition. Proper formatting is a critical procedural requirement in New York practice.
What are common coverage defenses in no-fault insurance?
Common coverage defenses include policy voidance due to material misrepresentation on the insurance application, lapse in coverage, the vehicle not being covered under the policy, staged accident allegations, and the applicability of policy exclusions. Coverage issues are often treated as conditions precedent, meaning the insurer bears the burden of proving the defense. Unlike medical necessity denials, coverage defenses go to whether any benefits are owed at all.
What happens if there's no valid insurance policy at the time of the accident?
If there is no valid no-fault policy covering the vehicle, the injured person can file a claim with MVAIC (Motor Vehicle Accident Indemnification Corporation), which serves as a safety net for people injured in accidents involving uninsured vehicles. MVAIC provides the same basic economic loss benefits as a standard no-fault policy, but the application process has strict requirements and deadlines.

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.
