InjuryPennsylvania gives you 2 years from the date of injury to file a personal injury lawsuit, under Title 42 §5524 of the Pennsylvania Consolidated Statutes. The clock generally starts on the date the injury occurred, with one important exception for cases where the harm isn't immediately obvious.
The Discovery Rule: When Injuries Aren't Immediately Apparent
Pennsylvania recognizes a discovery rule that can delay the start of the two-year clock until the point a reasonably diligent person would have discovered both the injury and that it was caused by another party's conduct. This matters most in cases involving latent injuries — certain medical conditions, product defects, or toxic exposures — where the harm may not be apparent right away.
💡 The discovery rule is an exception, not the default — for the large majority of personal injury cases (car accidents, slip and falls, dog bites), the standard two-year clock starts on the date of the incident itself.
Modified Comparative Fault: The 51% Bar
Separately from the filing deadline, Pennsylvania uses modified comparative fault with a 51% bar. If you're found 50% or less at fault for your own injury, you can recover damages reduced by your fault percentage; at 51% or more, you recover nothing.
Two Deadlines That Don't Follow the Standard Rule
Tolled Until Age 18
Under 42 Pa.C.S. §5533(b)(1), the two-year clock generally doesn't start running until the injured person turns 18 — giving a child injured at any age until their 20th birthday to file.
Only 6 Months to Give Notice
Claims against a state or local government agency require formal notice within 6 months of the incident under Pennsylvania's Sovereign Immunity and Tort Claims Acts — separate from, and much shorter than, the 2-year lawsuit deadline.
⚠️ The 6-month government notice deadline can be extended by up to 90 days if the injury itself physically incapacitated you and prevented you from giving notice — but absent that circumstance, missing the 6-month window can permanently bar a claim even though you'd still be well within the standard 2-year statute of limitations.
Why Acting Early Still Matters
Even with the discovery rule available for latent-injury cases, most personal injury claims in Pennsylvania run on the standard two-year clock from the date of the incident. Waiting to seek legal advice reduces the time available to gather evidence, identify witnesses, and build a strong claim before the deadline arrives — and can be fatal to a claim involving a government defendant.
