Medical malpractice lawsuits in New York follow strict procedural rules that do not apply to ordinary personal injury cases. Missing even one requirement can result in dismissal, regardless of how serious the injury may be. For patients harmed by medical negligence, understanding these rules is essential to preserving the right to compensation.
Medical malpractice occurs when a medical provider departs from accepted standards of care and causes injury or death. Because these cases involve complex medical issues and expert analysis, New York law requires early confirmation that a claim has medical merit. One of the most important requirements is the Certificate of Merit.
Under CPLR § 3012-a, most medical malpractice lawsuits filed in the New York Supreme Court must include a Certificate of Merit or file one shortly after the complaint. This document confirms that an attorney has consulted with a qualified medical expert who believes there is a reasonable basis for the claim. Its purpose is to prevent unsupported lawsuits while allowing valid cases to proceed.
This blog explains how the Certificate of Merit affects a medical malpractice lawsuit in New York, including filing requirements, exceptions, consequences of noncompliance, and its impact on case strategy and settlement.
If you or a loved one has been harmed by medical negligence, understanding New York’s strict medical malpractice requirements is essential. Missing a single procedural step, such as the Certificate of Merit, can jeopardize your case and prevent you from receiving the compensation you deserve.

What Is a Certificate of Merit in New York Medical Malpractice Litigation?
A Certificate of Merit in New York is a written statement signed by the plaintiff’s attorney confirming that they have consulted with a qualified healthcare professional who believes there is a reasonable basis to bring a medical malpractice claim. It serves as an early screening mechanism, ensuring that lawsuits are supported by medical opinion rather than speculation.
Although the document is signed by the medical malpractice attorney and not the medical professional, it must be based on a good-faith consultation. The consulting expert reviews relevant medical records and case details and concludes that the defendant may have departed from accepted standards of care. By filing the Certificate of Merit, the attorney certifies that this consultation occurred and that the claim is medically justified under New York law.
What New York Law Requires in a Certificate of Merit
Under CPLR § 3012-a, a valid Certificate of Merit must include the following elements:
| Required Element | Description |
|---|---|
| Attorney’s Affirmation | A sworn statement confirming that the attorney consulted with a qualified medical professional. |
| Expert’s Opinion | Confirmation that the consulted physician believes there is a reasonable basis for the malpractice claim. |
| Alternative Explanation | If consultation could not be obtained, a detailed explanation of the circumstances preventing it should be provided. This is interpreted narrowly by courts. |
Who Qualifies as a Consulting Physician?
The physician whose opinion forms the basis of the Certificate of Merit must meet the following criteria:
- Must be a physician licensed to practice medicine in the United States
- Not required by New York law to be board-certified
- Should have training, experience, or credentials in the same or a related medical specialty as the defendant
- Must be qualified to render an expert opinion on the applicable standard of care
- Opinion must be based on a review of relevant medical records and case facts, not speculation

Legal Requirements for a Certificate of Merit Under New York Law
CPLR § 3012-a governs Certificates of Merit (COM) in New York medical, dental, and podiatric malpractice cases. Compliance is essential for any injured patient pursuing a claim, as failure to file a valid COM can result in dismissal.
Timing Requirements
- Primary Rule: File the COM with the complaint or within 90 days after service of the complaint.
- Court Interpretation: Courts generally enforce the 90-day period strictly, though limited extensions may be granted for good-faith efforts.
- Extensions: Additional time may be granted if the attorney demonstrates reasonable cause for delay.
Three Types of Attorney Affirmations
Under CPLR § 3012-a, the COM can take one of three forms:
- Standard COM with Expert Consultation: Attorney certifies that a licensed physician reviewed the case and found reasonable grounds to pursue the claim.
- Statute of Limitations Exception: When the limitations period is about to expire, the attorney files a statement explaining that consultation could not be obtained in time despite diligent efforts.
- Records Unavailability Exception: The attorney certifies that necessary medical records were unavailable, preventing proper expert consultation before filing.
Limited Exceptions
A Certificate of Merit may not be required in specific circumstances, including:
- Statute of limitations is about to expire, and the attorney documents genuine efforts to secure expert consultation.
- Necessary medical records cannot be obtained despite reasonable efforts.
- Certain res ipsa loquitur cases, such as when surgical instruments or foreign objects are left inside the patient’s body.
Connection to the Statute of Limitations
Medical malpractice claims in New York are subject to strict deadlines:
| Situation | Time Limit |
|---|---|
| Standard cases | 2.5 years (30 months) from the negligent act or end of continuous treatment |
| Foreign objects | 1 year from discovery or when the object reasonably should have been discovered |
| Minors | Extended until the minor reaches majority, subject to specific rules |
| Wrongful death | 2 years from the date of death |
Important: Filing a Certificate of Merit does not pause or extend the statute of limitations. Failing to meet the deadline while attempting to obtain a COM can permanently forfeit the right to pursue compensation, even if the underlying medical negligence claim is strong.

How a Certificate of Merit Impacts the Course of a Medical Malpractice Lawsuit
The Certificate of Merit (COM) influences a New York medical malpractice case from the moment the complaint is filed. Courts, defense attorneys, and insurance carriers view a properly filed COM as an early signal that the claim is credible and supported by medical expertise.
Establishing Early Credibility
A COM based on a qualified specialist’s review immediately lends legitimacy to a case. When an attorney can show that a cardiologist, orthopedic surgeon, or other relevant expert has confirmed a deviation from the standard of care, it becomes much harder for defendants to label the claim as frivolous or speculative.
Key benefits of early credibility include:
- Reduces the risk of dismissal on procedural grounds
- Signals to defense counsel that thorough pre-litigation preparation has occurred
- Demonstrates to the court that the claim is backed by medical professionals
Impact on Motion Practice
Defendants frequently file motions to dismiss based on a missing or defective COM. A properly prepared certificate allows the plaintiff to:
- Survive early motions to dismiss
- Move into the discovery phase
- Avoid procedural delays that can extend the case unnecessarily
When the healthcare provider’s negligence is supported by expert review, the COM helps the case clear these initial hurdles and begin building a substantive claim.
Role in Settlement Negotiations
The COM also strengthens pre-suit and early settlement discussions. Certification that a qualified specialist supports the claim signals to insurance carriers that the plaintiff has a credible, expert-backed case.
Insurance companies recognize that claims involving surgical errors, anesthesia mistakes, incorrect medication, or inadequate follow-up care carry significant liability risk. A strong COM increases the likelihood of meaningful settlement negotiations and can sometimes encourage early resolution.
Foreshadowing Trial Strategy
The COM provides a preview of the expert testimony the plaintiff intends to present, shaping case strategy at every stage:
- Discovery Planning: Defendants anticipate the specialty and credentials of plaintiff experts
- Deposition Strategy: Both sides prepare questions and evidence relevant to expected expert testimony
- Independent Medical Examinations (IMEs): Defense counsel schedules their own experts in response
In effect, the COM validates the claim and sets the trajectory of the lawsuit, influencing pre-trial motions, settlement discussions, and trial preparation.

Consequences of Failing to Provide a Proper Certificate of Merit
Failure to comply with CPLR § 3012-a can have serious repercussions. In many cases, noncompliance leads to dismissal of the lawsuit, sometimes with prejudice, meaning the claim cannot be refiled—especially if deadlines have passed and the defect is not remedied.
Motion to Dismiss
Defendants can move to dismiss or strike a complaint if:
- The COM is not filed within the required timeframe
- Required language or certifications are missing
- The certificate is demonstrably inaccurate or not based on a proper physician consultation
This is more than a technicality. Experienced defense attorneys actively look for procedural defects to eliminate claims before they reach a jury.
Delays and Procedural Setbacks
Even if the case is not dismissed, failing to file a proper COM can cause significant delays:
- Discovery stays that halt case progress
- Denial of certain motions
- Additional hearings focused solely on procedural compliance
- Increased litigation time and costs
For injured patients, these delays add stress, financial burden, and uncertainty on top of medical recovery and treatment expenses.
Possible Remedies
Courts may allow late filing or amendments if:
- The statute of limitations has not expired
- No prejudice to the defendant is demonstrated
- Good faith efforts to comply were made
However, such relief is discretionary. Assuming the court will always grant an extension is a risky approach that can jeopardize a patient’s right to recover.
Permanent Loss of Rights
The most serious consequence occurs when dismissal happens after the statute of limitations has run. In such cases, the plaintiff may permanently lose the right to pursue compensation, regardless of how compelling the evidence of medical negligence may be.
This risk applies to cases involving:
- Birth injuries, including brain damage
- Traumatic brain injuries from delayed or missed diagnoses
- Cancer misdiagnosis or delayed treatment, including breast or prostate cancer
- Complications from improper medical treatment or therapy

Best Practices for Plaintiffs and Attorneys When Obtaining a Certificate of Merit
If you believe you have been the victim of medical negligence, it is critical to contact an experienced New York medical malpractice attorney promptly. Preparing a Certificate of Merit (COM) requires time, making early action essential.
Immediate Record Collection
Attorneys should request complete medical records without delay, including:
- Hospital charts
- Imaging studies (X-rays, MRIs, CT scans)
- Laboratory reports
- Prior treatment notes from all healthcare providers
- Documentation for any medical devices used
- Operative or procedure reports for surgeries or interventions
Consulting physicians cannot provide a reliable COM opinion based on partial information. Incomplete records may delay expert review and weaken the credibility of the certificate.
Selecting the Right Medical Expert
The consulting physician must have the appropriate specialty and practical experience for the alleged malpractice:
| Case Type | Appropriate Expert |
|---|---|
| Spinal surgery complications | Board-certified neurosurgeon |
| High-risk delivery injury | Maternal-fetal medicine specialist |
| Cardiac care negligence | Interventional cardiologist |
| Emergency room errors | Emergency medicine physician |
Experienced New York medical malpractice lawyers often maintain networks of qualified experts across specialties, enabling timely identification of the right consultant for any claim.
Prepare Well Before Deadlines
The COM should be ready well in advance of filing deadlines. Attorneys should maintain detailed internal notes, including:
- Dates when records were reviewed
- Specific documents examined
- Key deviations from the standard of care identified by the consulting physician
- Communications with the expert
These internal notes, while typically confidential, help support the validity of the certificate if later challenged.
Clear Client Communication
Patients should understand the purpose and limitations of a Certificate of Merit:
- It does not guarantee success in the case
- It confirms that the claim is based on a good-faith medical opinion
- It demonstrates the case is strong enough to proceed to litigation
A competent law firm will explain that the COM allows the case to move forward, but the burden of proof at trial remains with the plaintiff.
Working with Your NYC Medical Malpractice Lawyer
Patients play a critical role in building a strong case:
- Providing a complete medical history
- Promptly signing authorizations for release of records
- Reporting all symptoms, treatments, or changes in condition
- Being available to answer questions regarding care
Accurate and complete patient information helps attorneys present the most compelling case when a healthcare provider fails to meet the standard of care or misdiagnoses a condition.

Frequently Asked Questions
Is the Certificate of Merit the same as expert testimony at trial?
No. The Certificate of Merit (COM) is a preliminary certification based on a physician’s initial review of your case. Expert testimony at trial, in contrast, is far more detailed and subject to cross-examination. The doctor who provides the basis for the COM may or may not be the same expert who testifies at deposition or trial, depending on litigation strategy, availability, and privilege considerations.
The COM is generally not shown to the jury. Its primary function is procedural: it demonstrates to the court that a qualified medical professional has reviewed the case and determined that it has merit. The substantive testimony that persuades jurors comes later during standard litigation.
Do I, as the patient, ever see or sign the Certificate of Merit?
The COM is prepared, signed, and filed by your attorney—not by you. While the information it relies on comes from your medical records and history, you are not required to sign, notarize, or submit anything yourself.
You may request a copy of the filed COM if you wish. Your main responsibilities are to:
- Provide a complete medical history
- Promptly sign authorizations so your attorney can obtain all relevant records
- Answer questions about your treatment and symptoms
Can a medical malpractice case proceed in New York without a Certificate of Merit?
As a general rule, a COM is required for nearly all medical, dental, and podiatric malpractice cases filed in New York state courts. Narrow statutory exceptions exist, such as when the statute of limitations is about to expire and the attorney documents why expert consultation could not reasonably be obtained.
These exceptions are closely scrutinized by judges. Do not assume you qualify without legal advice tailored to your specific situation. Filing a case without a proper COM when no exception applies carries a high risk of dismissal.
What happens if the consulting doctor later changes their opinion?
Medical experts may revise their opinions as additional records, imaging, or test results become available during discovery. If an expert withdraws support for a claim, your New York City medical malpractice attorney may consult a different qualified physician.
Such changes can affect the case timeline, strategy, and potential settlement value. This highlights the importance of providing as complete a medical record as possible before obtaining the initial COM, so the consulting physician can make a fully informed assessment from the start.
