When a physician’s actions cause harm, determining whether the claim is medical malpractice or ordinary negligence can significantly impact your legal rights. A recent New York appellate decision highlights this important distinction—and New Jersey law follows similar principles that could affect your case.
The Lafferty v. Avila Decision
In August 2026, New York’s Appellate Division issued a notable ruling in Lafferty v. Avila that clarifies when a physician’s conduct constitutes medical malpractice versus ordinary negligence. Lafferty v. Avila, 2026 N.Y. App. Div. LEXIS 5353 (2026). The case involved a neurologist who allegedly recorded inaccurate information about a patient’s medical condition on a New York State Department of Motor Vehicles form used to evaluate whether the patient’s driver’s license should be reinstated. Lafferty v. Avila, 2026 N.Y. App. Div. LEXIS 5353 (2026).
The court had to decide a crucial question: Was this medical malpractice subject to a two-and-a-half-year statute of limitations, or ordinary negligence governed by a three-year limitations period? The answer could mean the difference between a viable claim and one that’s forever barred.
The appellate court concluded that the physician’s alleged negligence in completing the DMV form implicated ordinary negligence principles, not medical malpractice. Lafferty v. Avila, 2026 N.Y. App. Div. LEXIS 5353 (2026). This determination allowed the plaintiffs’ claims to proceed under the longer statute of limitations. The court’s reasoning turned on the nature of the alleged wrongful act and whether it required the specialized skill and judgment inherent in the physician-patient treatment relationship.
New Jersey’s Approach to the Medical Malpractice vs Negligence Distinction
New Jersey courts apply similar analytical frameworks when distinguishing between medical malpractice and ordinary negligence claims against healthcare professionals. The key question is not simply the label placed on the action, but rather the nature of the legal inquiry. Couri v. Gardner, 173 N.J. 328, 330 (2002).
Under New Jersey law, when determining whether a claim requires an affidavit of merit—a procedural requirement specific to professional malpractice cases—courts must assess “if the claim’s underlying factual allegations require proof of a deviation from the professional standard of care applicable to that specific profession.” Mazur v. Crane’s Mill Nursing Home, 441 N.J. Super. 168, 183 (2015). If expert testimony establishing a deviation from professional standards is necessary, the claim sounds in malpractice. Triarsi v. BSC Group Servs., LLC, 422 N.J. Super. 104, 112 (2011).
New Jersey’s Affidavit of Merit statute, N.J.S.A. 2A:53A-26 to -29, requires plaintiffs in malpractice actions to provide an affidavit from an appropriate licensed professional confirming “a reasonable probability that the care, skill or knowledge exercised or exhibited in the treatment, practice or work that is the subject of the complaint, fell outside acceptable professional or occupational standards or treatment practices.” N.J. Stat. § 2A:53A-27. This requirement applies to claims against physicians and other licensed healthcare professionals. N.J. Stat. § 2A:53A-26 (2019).
However, not all negligent acts by healthcare professionals constitute medical malpractice. Medical malpractice is “a kind of tort action in which the traditional negligence elements are refined to reflect the professional setting of a physician-patient relationship.” Worthy v. Kennedy Health System, 446 N.J. Super. 71, 91 (2016). To establish medical malpractice, a plaintiff must present expert testimony establishing: (1) the applicable standard of care; (2) a deviation from that standard; and (3) that the deviation proximately caused the injury. Worthy v. Kennedy Health System, 446 N.J. Super. 71, 91 (2016), Haviland v. Lourdes Medical Center of Burlington County, Inc., 250 N.J. 368, 383 (2022).
Where the common knowledge doctrine applies—meaning the negligence is apparent to anyone of average intelligence and ordinary experience—expert testimony may not be required, and the claim may be treated more like ordinary negligence. Rosenberg v. Cahill, 99 N.J. 318, 325 (1985), Zuidema v. Pedicano, 373 N.J. Super. 135, 148 (2004). For instance, New Jersey courts have recognized that extracting the wrong tooth is negligent as a matter of common knowledge. Hubbard v. Reed, 168 N.J. 387, 396 (2001). Similarly, a pharmacist filling a prescription for one medication with a completely different drug would fall within common knowledge. Bender v. Walgreen Eastern Co., Inc., 399 N.J. Super. 584, 592 (2008).
