Harder than most people expect, and deliberately so. Connecticut puts a hurdle in front of medical malpractice cases that does not exist for a car crash or a slip and fall: before you can even file, the law requires a written opinion from a qualified medical professional saying there appears to be real evidence of negligence. Get that step wrong and the case can be dismissed before anyone looks at the merits.
This is not meant to discourage you. It is meant to explain why these cases need a lawyer involved early, and why “I think my doctor made a mistake” is the beginning of the process, not the end of it.
The Requirement That Makes Connecticut Different
Under Connecticut General Statutes § 52-190a, you cannot simply file a medical malpractice lawsuit. First, your attorney has to make a reasonable pre-suit inquiry into whether there are grounds for a good faith belief that a health care provider was negligent.
To back that up, the law requires two things attached to the complaint:
- A certificate of good faith, signed by the attorney, stating that this reasonable inquiry gave rise to a good faith belief that grounds for the action exist, and
- A written, signed opinion from a “similar health care provider” stating that there appears to be evidence of medical negligence.
In plain terms: before you sue, a qualified medical professional in the right field has to review the care and put their name to the conclusion that something appears to have gone wrong. No opinion letter, no case.
What “Similar Health Care Provider” Means, and Why It Trips Cases Up
The opinion cannot come from just any doctor. It has to come from a provider similar enough to the one you are suing, generally in the same specialty or field. An opinion from a mismatched specialty can be ruled insufficient, and that alone can sink a complaint.
Connecticut courts also require the letter to have a detailed basis, not just a conclusion. Under the Connecticut Supreme Court’s decision in Wilcox v. Schwartz, the opinion has to state the applicable standard of care, the fact that it was breached, and the factual basis for that conclusion. A letter that simply says “this looks like malpractice” without explaining how the standard of care was breached can be found legally insufficient.
This is exactly the kind of technical requirement that ends cases filed without experienced counsel. The underlying care may have been genuinely negligent, but a defective opinion letter can end the lawsuit anyway.
Not Everything That Goes Wrong in a Hospital Is “Malpractice”
An important distinction: not every injury that happens during medical care is a medical malpractice claim in the legal sense, and the difference decides whether the opinion-letter requirement even applies.
When an injury results from a professional medical judgment or treatment decision, it is medical malpractice, and § 52-190a applies. But when an injury results from ordinary carelessness that happens to occur in a medical setting, Connecticut courts have treated it as ordinary negligence, which does not require the opinion letter. Classic examples from Connecticut cases involve a patient injured when a gurney is pushed into a wall, or a fall unrelated to a treatment decision. Those can sound in ordinary negligence rather than malpractice.
Getting this characterization right matters, because it determines what you have to file and what deadlines and requirements apply. It is not always obvious from the outside which category a given injury falls into.

Informed Consent Is Its Own Path
Claims that a provider failed to obtain proper informed consent are treated differently. Connecticut applies a lay standard to informed-consent claims, and they do not require an opinion from a similar health care provider the way a negligence claim does. It is a separate track with its own rules, which is another reason the early legal analysis of what kind of claim you actually have is so important.
The Deadline Has a Wrinkle Built In
Medical malpractice claims are subject to Connecticut’s personal injury deadlines, which come with their own two-year rule and a hard outer limit.
Medical malpractice claims are subject to Connecticut’s personal injury deadlines, which come with their own two-year rule and a hard outer limit. Because getting a proper opinion letter takes time, § 52-190a includes a mechanism that allows a limited extension of the filing deadline to obtain that opinion.
The interaction between the malpractice filing deadline and the opinion-letter requirement is one of the trickier timing questions in this area, and it is not something to work out on your own near a deadline. If you think you may have a malpractice claim, the time to get it evaluated is well before any deadline is close.

What This Means If You Think You Have a Case
The takeaway is not that Connecticut malpractice cases are impossible. It is that they are front-loaded. The hard work, obtaining medical records, finding and retaining an appropriate similar health care provider, and getting a sufficient opinion letter, has to happen before the lawsuit is even filed. That is very different from other injury cases, and it is why these matters need a lawyer involved as early as possible.
If you believe you or a family member was harmed by negligent medical care in Connecticut, the useful next step is an evaluation, not a self-diagnosis of the legal claim. A lawyer can obtain the records, arrange the right medical review, and determine whether the case can meet the requirements the law imposes.
Baber Law handles Connecticut medical malpractice claims on a contingency basis. There is no fee unless we recover for you, and the consultation is free. If you think something went wrong with your medical care, let us review it before any deadline gets close.
This article explains Connecticut law generally. It is not legal or medical advice, and reading it does not create an attorney-client relationship. Whether a particular situation qualifies as medical malpractice depends on the specific facts and on medical review. If you have concerns about medical care you received, speak with a lawyer promptly, because strict deadlines apply.
