“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.

About This Topic

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.

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.
