Affidavits serve as crucial evidence in New York litigation, but their effectiveness depends entirely on proper form and execution. Courts regularly scrutinize these sworn statements to ensure they meet basic legal requirements, and even minor defects can render them inadmissible. Understanding the minimum standards for a valid affidavit can save attorneys and litigants from costly procedural errors that might derail their cases.
The New York Appellate Division, Second Department, recently clarified these requirements in a decision that provides helpful guidance for practitioners. This ruling demonstrates how courts evaluate affidavit form and what elements are absolutely necessary for acceptance. For attorneys handling summary judgment motions or other proceedings requiring sworn testimony, these standards are particularly important to understand.
Jason Tenenbaum’s Analysis:
Furtow v Jenstro Enters., Inc., 2010 NY Slip Op 05987 (2d Dept. 2010)
“Here, Ching submitted an affidavit which recited that he was “duly sworn” and contained a jurat stating that the affidavit was “sworn to before” a notary public, who signed and stamped the document. On the record presented here, the form of the affidavit was adequate (see Sirico v F.G.G. Prods., Inc., 71 AD3d 429; Sparaco v Sparaco, 309 AD2d 1029, 1030; Feinman v Mennan Oil Co., 248 AD2d at 504; Collins v AA Truck Renting Corp., 209 AD2d at 363).”
The affidavit at a minimum must say this: John Doe, DULY SWORN….
Sworn to before
notary public
Key Takeaway
New York courts require affidavits to contain specific language stating the affiant was “duly sworn” and include proper notarization with a jurat indicating the document was “sworn to before” a notary public. While courts may allow clarifying affidavits when defects exist, meeting these minimum requirements from the start ensures admissibility and avoids potential delays in litigation.

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 are the requirements for a valid affidavit in New York?
Under CPLR 2309, an affidavit must be sworn before a notary public or other authorized officer. It must contain statements of fact based on the affiant's personal knowledge — not conclusions, opinions, or hearsay. The affiant must be identified, the oath properly administered, and the document signed and notarized.
Can an affirmation substitute for an affidavit in New York?
Only if the affirmant is an attorney, physician, dentist, or podiatrist under CPLR 2106. These professionals may submit unsworn affirmations under penalty of perjury instead of notarized affidavits. All other individuals must use properly notarized affidavits.
What happens if an affidavit is defective in a no-fault case?
A defective affidavit — one lacking personal knowledge, improperly notarized, or containing inadmissible hearsay — may be rejected by the court. This can be fatal to a motion for summary judgment, whether brought by the insurer or the claimant. Courts strictly enforce affidavit requirements in no-fault litigation.
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.

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.
