Reviewed by Laurence P. Banville, Esq.Step 1: Records Collection and Medical Review
Every medical malpractice case starts with the chart. We request the complete treatment record — office notes, hospital records, imaging, nursing notes, and any internal incident reports we’re entitled to — and send it to a qualified physician in the same specialty as the defendant for an independent review. That reviewing doctor tells us whether the care fell below the accepted standard and whether that departure caused the injury. This step happens before drafting anything for court, because New York doesn’t allow a malpractice suit to be filed on a hunch.
Step 2: The Certificate of Merit
New York is one of a handful of states that requires a certificate of merit under CPLR § 3012-a to accompany (or follow within 90 days of) the complaint in every medical, dental, or podiatric malpractice case. The attorney must certify that they consulted with a physician who concluded, based on a review of the facts and records, that there is a reasonable basis to believe the defendant departed from accepted standards of care. Filing without this certificate — or filing on a defective one — can expose a case to early dismissal, which is why the expert review in Step 1 has to happen first, not after the fact.
Step 3: Filing the Summons and Complaint
Once the medical review supports the claim, we file the summons and complaint in New York Supreme Court in the proper county and serve every defendant — the doctor, the hospital, the practice group, whoever’s conduct is at issue. The complaint lays out the factual allegations: who owed a duty of care, how that duty was breached, and how the breach caused injury. This filing must happen within New York’s statute of limitations for medical malpractice, which is generally shorter than for ordinary negligence claims, so timing this step correctly matters as much as getting the substance right.
Step 4: Discovery and Depositions
After the defendants answer, the case moves into discovery under CPLR Article 31. Both sides exchange medical records, hospital policies, prior similar incidents, and written interrogatories, then take depositions — sworn, recorded testimony — of the treating providers, hospital staff, and often the patient. This phase is where the paper record gets tested: inconsistencies between what a chart says and what a provider testifies to often become central to the case.
Step 5: Expert Testimony
Discovery closes with expert disclosure, where each side identifies the physicians who will testify at trial about the standard of care, the departure from it, and causation. Because a jury of laypeople can’t be expected to know what a reasonable surgeon, radiologist, or obstetrician should have done, New York law requires expert testimony to establish malpractice in nearly every case — the certificate of merit gets the case filed, but trial-ready expert testimony is what proves it.
Step 6: Settlement or Trial
Most medical malpractice cases resolve before trial, often through mediation or direct negotiation once both sides have seen the full discovery record and expert opinions. What a case is worth depends on the severity and permanence of the injury, the strength of the liability evidence, the defendant’s insurance coverage, and how the case would likely play to a jury — there’s no fixed formula, and prior results do not guarantee or predict a similar outcome in any other case. If a fair resolution isn’t reached, the case proceeds to trial, where the jury hears the evidence and expert testimony developed through discovery and decides the outcome.
Frequently asked questions
How do I file a medical malpractice lawsuit in New York?
You start by getting your full medical record reviewed by a qualified physician to confirm the care fell below the accepted standard. Your attorney then files a summons and complaint in New York Supreme Court along with a CPLR § 3012-a certificate of merit, and serves all named defendants.
What is a certificate of merit?
A certificate of merit is a filing required under CPLR § 3012-a in every New York medical, dental, or podiatric malpractice case. It certifies that the attorney consulted a physician who reviewed the facts and concluded there is a reasonable basis to believe the defendant departed from accepted medical standards.
Do I need an expert witness to file?
You need a physician's review before filing to support the certificate of merit, though that reviewing doctor doesn't have to be publicly named yet. A separate testifying expert is identified later, during discovery, to give the standard-of-care and causation testimony a jury needs at trial.
What are the steps in a medical malpractice case?
The typical sequence is: medical record review, filing the summons, complaint, and certificate of merit, discovery and depositions, expert disclosure, and then settlement negotiations or trial. Each step builds the evidentiary record the next step depends on.
How does a medical malpractice lawsuit work?
It works by building proof in stages — a physician confirms the claim has merit, the case gets filed and served, both sides exchange records and take depositions, and experts on both sides weigh in on the standard of care and causation. Most cases settle once that record is fully developed, though some proceed to a jury trial.
