The Chapter 74 two-year rule, the 10-year statute of repose, and the tolling exceptions that can save — or sink — a Texas malpractice claim.
Texas Civil Practice & Remedies Code § 74.251 — part of the Texas Medical Liability Act — gives most medical-malpractice plaintiffs two years to file a lawsuit. The clock starts on the date of the negligent act, the last day of treatment for the condition at issue, or the end of the hospitalization that gave rise to the claim — whichever is latest.
Two years sounds like a long time. In practice it is short. A Texas malpractice case requires obtaining medical records, identifying the right defendants, preparing a 60-day pre-suit notice, and lining up a qualified medical expert who can author a Chapter 74 expert report within 120 days of filing.
The page below walks through the rule, the major exceptions, and the procedural deadlines that follow once you do file.
Section 74.251(a) gives three possible start dates and tells the court to use whichever is latest:
The date the doctor, nurse, or hospital did (or failed to do) the thing that caused the harm.
The last day the provider treated the specific condition at issue — relevant for ongoing care like chemotherapy or prenatal management.
The date of discharge from the hospitalization that gave rise to the claim.
Important: Texas does not generally apply a discovery rule under Chapter 74. The clock typically runs from the negligent act, not from when you discovered the harm.
For children under 12 at the time of the negligence, the lawsuit must be filed before the child's 14th birthday. Texas appellate courts have used the constitutional open-courts doctrine in some cases to extend that deadline.
When a surgical sponge, needle, or instrument is unintentionally left inside a patient, the two-year clock runs from discovery — not from the original procedure. See our surgical-error practice page for more.
When a healthcare provider actively conceals their negligence — by altering records or hiding a known complication — the statute of limitations may be tolled until the patient discovers, or reasonably could have discovered, the underlying malpractice.
Article I, § 13 of the Texas Constitution prohibits the legislature from cutting off a well-established cause of action through an unreasonable filing deadline. When the strict 2-year rule would deny a plaintiff any meaningful chance to discover the injury and file in time, the Texas Supreme Court has held the limitations period unconstitutional as applied.
Section 74.251(b) creates an absolute outer limit: no medical-malpractice claim may be filed more than 10 years after the date of the negligent act or omission. The repose statute generally cannot be tolled, extended by the discovery rule, or waived.
If your potential claim is approaching the 10-year mark, treat it as urgent.
Section 74.051 requires written notice with a medical-records authorization served on each potential defendant at least 60 days before filing.
Filing must occur on or before the 2-year deadline.
Within 120 days of filing, plaintiffs must serve a qualified medical expert report under § 74.351. Failure to serve a timely report results in dismissal — with attorney's fees awarded against the plaintiff.
Past 10 years, the statute of repose generally bars the case forever.
Texas Civil Practice & Remedies Code § 74.251 sets a two-year deadline for medical and dental liability claims. The clock generally begins on the date of the negligent act or omission, the date the medical or dental treatment that gave rise to the claim was completed, or the date the hospitalization for which the claim is made was completed — whichever is latest. Missing this deadline almost always means losing the right to sue forever, so the safest course is to consult a qualified attorney as soon as you suspect a problem.
Texas does not generally apply a discovery rule to medical-malpractice claims under Chapter 74 — the clock typically runs from the act of negligence, not from the date you discovered it. There are two important exceptions: (1) the foreign-object rule, which resets the clock to discovery when a sponge, instrument, or similar object is unintentionally left inside the body, and (2) the Texas Constitution's open-courts doctrine, which can extend the deadline when applying a strict cutoff would unconstitutionally cut off your right to sue before you reasonably could have known of the injury.
Texas § 74.251(a) provides that for children under the age of 12 at the time of the negligent act, the action must be filed before the child's 14th birthday. However, Texas appellate courts have applied the open-courts doctrine in some situations to extend that deadline when applying it strictly would deprive a minor of a meaningful chance to bring a constitutionally protected claim. Because the rule is unsettled at the edges, parents should never assume they have unlimited time — speak with a Texas medical-malpractice attorney as soon as possible.
Section 74.251(b) imposes an absolute 10-year outer limit on medical-malpractice claims, measured from the date of the negligent act or omission. The repose statute is a hard ceiling — even valid tolling, the discovery rule, or open-courts arguments cannot generally push a claim past 10 years. Narrow constitutional exceptions exist but are difficult to invoke. If your potential claim is approaching the 10-year mark, you should treat the matter as urgent.
