What Is the Medical Malpractice Statute of Limitations in CT?

The medical malpractice statute of limitations in Connecticut gives you two years from the date you discover the injury to file suit, with a hard three-year cutoff measured from the date of the negligent act itself.¹ Both clocks run at the same time, and whichever expires first ends your right to sue. These are among the shortest malpractice deadlines in the country, and Connecticut does not pause them for children.

When the Two-Year Clock Starts

Under Connecticut General Statutes § 52-584, the two-year period begins when you first sustain or discover the injury, or when you reasonably should have discovered it.¹ Discovery means more than a vague sense that something is off. You have to be aware both that you were injured and that the injury may be tied to your medical care.

The distinction matters most in slow-developing cases. A surgical sponge left behind may cause no symptoms for months. Once you learn about it, or once symptoms become obvious enough that a reasonable person would investigate, the two-year window opens. Courts look at whether you exercised ordinary diligence in monitoring your health after treatment. Ignoring clear warning signs can shorten your effective filing time, because a judge may decide you should have discovered the problem earlier than you actually did.

The Three-Year Absolute Cutoff

Even if you had no reason to suspect anything went wrong, Connecticut imposes a three-year deadline measured from the date of the negligent act or omission.¹ This is a statute of repose, and it operates independently of the discovery rule. If a radiologist misreads a scan and you don’t learn about it until four years later, the repose period bars your claim no matter how reasonable your delay was.

The practical effect is that both deadlines run in parallel. You need to file within two years of discovery and within three years of the act, and whichever arrives first controls. Most people get tripped up here, because they focus on when they learned about the problem rather than when the error actually happened.

When the Deadline Can Pause

Continuous Treatment by the Same Provider

One of the few paths around the three-year repose deadline involves ongoing care by the same provider who committed the error. Connecticut courts recognize a continuous treatment doctrine that can toll the repose period when a patient remains under the same provider’s active care for the same condition. The Connecticut Supreme Court set out a three-part test in Grey v. Stamford Health Systems covering the identified condition, continued provider involvement, and timely filing after the treatment ends.²

The reasoning is straightforward. You cannot reasonably be expected to sue a doctor who is still actively treating you for the very condition at issue. The repose clock pauses during that ongoing treatment and resumes once the treatment relationship ends. Routine checkups with the same practice do not automatically qualify. The treatment must be specifically related to the condition tied to the alleged negligence.

Fraudulent Concealment

If a medical provider actively hides the existence of your claim, Connecticut General Statutes § 52-595 allows the statute of limitations to restart from the moment you discover the concealment.³ This is a narrow exception with a high bar. Simply failing to mention an error does not meet the threshold. Courts look for affirmative acts, such as falsifying medical records, deliberately misrepresenting test results, or actively lying about what happened during a procedure. The provider must have known about the malpractice and specifically intended to keep you from discovering it.

Wrongful Death Has Its Own Deadlines

When a patient dies from medical negligence, the filing deadlines shift. Under Connecticut General Statutes § 52-555, the executor or administrator of the estate must file suit within two years of the date of death, and the statute of repose extends to five years from the date of the negligent act or omission.⁴ That five-year repose is notably longer than the three-year window for standard malpractice claims.

Only the executor or administrator of the estate has standing to bring the action. Recoverable damages include medical and hospital expenses, nursing costs, and funeral expenses, along with compensation for the wrongful death itself.⁴ Families often delay legal steps after a death, and the two-year window can close faster than expected when probate is still getting organized.

Children Get the Same Deadlines as Adults

This is one of Connecticut’s harshest rules. The state does not toll the statute of limitations for minors in medical malpractice cases. Children are subject to the same two-year discovery and three-year repose deadlines as adults under § 52-584.¹ Connecticut courts have confirmed that the statute cannot be read as containing an implied exception for unemancipated minors.

The consequences are significant. A birth injury that leaves a child needing lifelong care must still be brought to court within three years of the negligent act. If parents don’t recognize the harm or don’t consult a lawyer in time, the child permanently loses the right to seek compensation. Many states pause the clock until a minor turns 18. Connecticut does not. The burden falls squarely on parents and guardians to investigate and act quickly.

Government and Municipal Hospitals Have Shorter Notice Deadlines

Suing a state-run or municipal hospital adds procedural layers on top of the standard malpractice clock. If the negligent provider works for a Connecticut municipality, you must file written notice of your intent to sue with the town clerk within six months of the date the injury occurred.⁵ The lawsuit itself must then be filed within two years. Missing the six-month notice window can kill an otherwise valid claim before it starts.

Claims against state agencies and state-operated medical facilities follow a different path. You must file a notice of claim with the Office of the Claims Commissioner, generally within one year of when the injury accrued, with an absolute three-year repose period from the date of the act or omission.⁶ The state has sovereign immunity, so you cannot proceed in regular court without the Claims Commissioner’s authorization.

The 90-Day Extension for the Expert Opinion

Before you can file any medical malpractice lawsuit in Connecticut, your complaint must include a certificate of good faith from your attorney along with a written opinion from a qualified medical expert.⁷ Because assembling that opinion takes time, § 52-190a(b) lets you petition the clerk of any Superior Court or federal district court for an automatic 90-day extension of the statute of limitations.

The extension applies on top of any other tolling that might be in effect. It is not a substitute for careful deadline tracking. If you are already close to the three-year repose deadline and have not secured an expert, the extension buys limited breathing room. Attorneys who handle these cases regularly start the expert search months before any deadline is close, because finding the right specialist, getting them the records, and receiving a written opinion is rarely quick.
