Midfirst Bank v Agho, 2014 NY Slip Op 05778 (2d Dept. 2014)

“Our Court is observing a significant upswing in the number of appeals where the parties are contesting the admissibility of affidavits executed outside of the state, without CPLR 2309(c) certificates of conformity.”

(Supreme Court denied motion for leave to enter default due to failure to comply with CPLR 2309)

Held to comply with 2309(c)

“Mills’s affidavit was executed in the County of Oklahoma, State of Oklahoma, on September 20, 2012. The jurat reads:

State of Oklahoma

County of Oklahoma

Subscribed and sworn to (or affirmed) before me this 20th of September, 2012, by Josh Mills, provided to me the basis of satisfactory evidence to be the person(s) who appeared before me.

Signature Mark R. Pitts (Notary Seal)

Notary Public”

The Notary Seal contained Pitts’s name and notary number, and the future expiration date of his notary license.

The affidavit and jurat were accompanied by a further document called a “Uniform, All Purpose Certificate of Acknowledgment.”

The Certificate of Acknowledgment read:

UNIFORM, ALL PURPOSE CERTIFICATE OF ACKNOWLEDGMENT

(Must sign in addition to Jurat if signed outside of New York State)

“State of Oklahoma

County of Oklahoma

On the 20th day of September in the year of 2012 before me, the undersigned, personally appeared Josh Mills, personally known to me or proved to me on the basis of satisfactory evidence to be the individual(s) whose name(s) is (are) subscribed to the within instrument and acknowledged to me that he/she/they executed same in his/her/their capacity(ies) and that by his/her/their signature(s) on the instrument, the individual(s), or the person upon behalf of which the individual(s) acted, executed the instrument, and that such individual made such appearance before the undersigned in Oklahoma City, Oklahoma (insert the city or other political subdivision and the state or county or other place the acknowledgment was taken).”

“The “certificate” required by CPLR 2309(c), commonly referred to in case law as a “certificate of conformity,” must contain language attesting that the oath administered in the foreign state was taken in accordance with the laws of that jurisdiction or the law of New York (see Real Property Law § 299-a)”

“Here, the Supreme Court erred in concluding that the Mills affidavit was not accompanied by a certificate of conformity, as the “Uniform, All Purpose Certificate of Acknowledgment,” appended to the Mills affidavit, substantially conformed with the template requirement of Real Property Law § 309-b and constituted a certificate of conformity. The “Uniform, All Purpose Certificate of Acknowledgement” attested that the notary public, Mark R. Pitts, confirmed Josh Mills’s identity when Mills executed his affidavit in Pitts’ presence on the date the affidavit was executed, and was signed by Pitts alongside his notary seal. Moreover, since Mills’s signature upon the affidavit was acknowledged by a notary licensed in Oklahoma, no separate certificate of authentication was required (see Real Property Law §§ 299, 311).”

The most important part of the opinion is here:

“Parenthetically, we note that even if the Mills affidavit was not accompanied by a certificate of conformity, the Appellate Division, Second Department, has typically held, since 1951, that the absence of a certificate of conformity is not, in and of itself, a fatal defect (see Mack-Cali Realty, L.P. v Everfoam Insulation Sys., Inc., 110 AD3d at 680; Bey v Neuman, 100 AD3d at 582;Fredette v Town of Southampton, 95 AD3d at 941; Fallah v Stop & Shop Cos., Inc., 41 AD3d at 639; Smith v Allstate Ins. Co., 38 AD3d at 523; Raynor v Raynor, 279 App Div 671). The defect is not fatal, as it may be corrected nunc pro tunc (see U.S. Bank N.A. v Dellarmo, 94 AD3d 746), or pursuant to CPLR 2001, which permits trial courts to disregard mistakes, omissions, defects, or irregularities at any time during an action where a substantial right of a party is not prejudiced (_see Matos v Salem Truck Leasing,_105 AD3d at 917; Rivers v Birnbaum, 105 AD3d at 44; Betz v Daniel Conti, Inc., 69 AD3d at 545). Thus, even if the certificate of conformity was inadequate or missing, no substantial right of the defendants is prejudiced. As they failed to oppose the plaintiff’s motion or raise the issue, it was inappropriate for the Supreme Court to, sua sponte, do so on the defendants’ behalf (see Rosenblatt v St. George Health & Racquetball Assoc., LLC, _____ AD3d _____, 2014 NY Slip Op 02917 ). ”


Legal Update (February 2026): Since this 2014 decision, CPLR 2309(c) requirements for out-of-state affidavits may have been subject to amendments or clarifications through subsequent court decisions and rule revisions. Additionally, procedural requirements under CPLR 2001 regarding court discretion in curing defects may have evolved. Practitioners should verify current conformity certificate requirements and formatting standards for out-of-state affidavits in no-fault insurance proceedings.

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. These articles analyze the formal requirements, common defects, and court decisions that practitioners must navigate when preparing sworn statements.

Common Questions

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 procedural defenses in New York no-fault litigation?

Common procedural defenses include untimely denial of claims (insurers must issue denials within 30 days under 11 NYCRR §65-3.8(c)), failure to properly schedule EUOs or IMEs, defective service of process, and failure to comply with verification request requirements. Procedural compliance is critical because courts strictly enforce these requirements, and a single procedural misstep by the insurer can result in the denial being overturned.

What is the CPLR and how does it affect my case?

The New York Civil Practice Law and Rules (CPLR) is the primary procedural statute governing civil litigation in New York state courts. It covers everything from service of process (CPLR 308) and motion practice (CPLR 2214) to discovery (CPLR 3101-3140), statute of limitations (CPLR 213-214), and judgments. Understanding and complying with CPLR requirements is essential for successful litigation.

Understanding New York 2106 and 2309 Law

New York has a unique legal landscape that affects how 2106 and 2309 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 2106 and 2309 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. Whether you need representation in a no-fault arbitration, a personal injury trial, an employment discrimination hearing, or an appeal to the Appellate Division, the Law Office of Jason Tenenbaum, P.C. brings $24+ years of real courtroom experience to your case. 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.
