Statute of Limitations
The legal deadline by which a malpractice plaintiff must file suit, typically measured from the date of the negligent act or the date the injury was or should have been discovered.
Also known as: limitations period, filing deadline, SOL
What it is
A statute of limitations is a state law that fixes the maximum time after an alleged injury within which a plaintiff may file suit. In medical malpractice, the period typically runs one to four years depending on the state, often measured from the date of the negligent act, sometimes from the date the injury was discovered or reasonably should have been discovered (the "discovery rule").
How it interacts with discovery
Most malpractice statutes incorporate a discovery rule because injuries from negligent care can take years to manifest (a missed cancer diagnosis, a retained surgical instrument, gradual organ damage). The discovery rule extends the filing window to the point at which a reasonable patient would have connected the injury to the underlying care. Some states cap the discovery extension with an outer "statute of repose" that bars suits filed after a fixed period (often 4 to 10 years) regardless of when the injury was found.
Special tolling for minors
Most states toll the limitations period for plaintiffs who were minors at the time of injury, allowing the clock to start running when the plaintiff reaches majority. Tolling rules vary widely; some states have age-based outer limits.
In settlement strategy
The limitations analysis is the very first step in case intake. A case filed one day late is unwinnable regardless of the merits. Plaintiff attorneys evaluating an older injury must reconstruct the discovery timeline carefully; defense counsel will move to dismiss on limitations grounds before responding to the substantive allegations.
