Full Text of CPLR 3012-a
Plain-English Summary
Malpractice suits against doctors, dentists, and podiatrists carry real stakes for professionals whose licenses and reputations are on the line, and CPLR 3012-a builds in an early check against filing one without any grounding. The complaint in such a case must come with a certificate, signed by the plaintiff's attorney, and the attorney has to choose one of three things to certify.
The usual route is certifying that the attorney reviewed the facts, consulted with at least one physician, dentist, or podiatrist licensed in New York or elsewhere who the attorney reasonably believes is knowledgeable about the issues involved, and concluded from that review and consultation that the action has a reasonable basis. When time doesn't allow for that step before filing — because the statute of limitations would otherwise expire — the attorney can certify that instead, and the real certificate has ninety days after the complaint is served to follow. And if the attorney tried, in good faith, to consult three separate qualified professionals and none would agree to consult, the attorney can certify that instead of the underlying opinion itself.
Only one certificate is required per action, even if more than one defendant is named or added later. If the attorney intends to rely entirely on res ipsa loquitur, the section doesn't apply in its usual form — the attorney instead files a certificate saying so. And if the plaintiff requested treatment records that haven't been produced, the deadline to serve the certificate is pushed back to ninety days after the records finally arrive.
The statute also protects the process from becoming its own discovery fight. The identity of the consulted professional and the substance of that consultation don't have to be disclosed, except that if the attorney claims no professional would agree to a consultation, the court can require the attorney to name the ones who declined, if a defendant asks before certain disclosure requirements are met. None of this applies to a plaintiff who isn't represented by an attorney, and a plaintiff may choose to give the defendant specified information about the case instead of serving the certificate.
Frequently Asked Questions
What is a certificate of merit in a New York medical malpractice case?
It's a certificate the plaintiff's attorney must file with the complaint, confirming that a qualified physician, dentist, or podiatrist was consulted and that the attorney concluded there is a reasonable basis for the action.
Do I need an expert consultation before filing a malpractice complaint in New York?
Generally yes, unless the statute of limitations would run out before consultation is possible, or the attorney made three separate good-faith attempts to consult and no professional agreed.
What happens if the statute of limitations is about to run before I can consult an expert?
The attorney can certify that the time limit forced filing before consultation was possible, and then has ninety days after the complaint is served to file the certificate that would otherwise have been required.
Do I need a separate certificate of merit for each defendant in a malpractice suit?
No. CPLR 3012-a requires only a single certificate for each action, even if more than one defendant is named or later added.
Is a certificate of merit required if I represent myself in a malpractice case?
No. The section states its provisions do not apply to a plaintiff who is not represented by an attorney.
Does relying on res ipsa loquitur change the certificate of merit requirement?
Yes. If the attorney intends to rely solely on res ipsa loquitur, the usual certificate isn't required; instead the attorney files a certificate stating that reliance and explaining why no other certificate is being filed.
