Pennsylvania gives you 2 years from the date of injury to file a personal injury lawsuit, under Title 42 ยง5524 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 โ€” certain medical conditions, product defects, or toxic exposures โ€” where the harm may not be apparent right away.

๐Ÿ’ก The discovery rule is an exception, not the default โ€” 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

Injured Minor

Tolled Until Age 18

Under 42 Pa.C.S. ยง5533(b)(1), the two-year clock generally doesn't start running until the injured person turns 18 โ€” giving a child injured at any age until their 20th birthday to file.

Government Defendant

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 โ€” separate from, and much shorter than, the 2-year lawsuit deadline.

โš ๏ธ 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 โ€” 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 โ€” and can be fatal to a claim involving a government defendant.

What to Do First After an Injury in Pennsylvania

Pennsylvania has several features that can change how a claim proceeds, from its choice of auto insurance coverage types to short government notice periods. A practical sequence:

  1. Get medical care and keep complete records. If your symptoms appeared later, record when you first noticed them, since the discovery rule described above depends on that timeline.
  2. If a vehicle was involved, find out whether your policy selected limited tort or full tort, because the choice affects your ability to recover non-economic damages. Ask an attorney to read your policy.
  3. Check for public defendants. The 6-month notice rule applies to claims against government agencies, and the short window runs from the incident.
  4. For snow and ice falls, Pennsylvania courts have applied special rules that can make claims more demanding, so photograph conditions and note when the weather occurred.
  5. For medical claims, Pennsylvania generally requires a certificate of merit from a qualified professional soon after a professional-liability complaint is filed.
  6. Avoid early releases and recorded statements until you understand your injuries.

How Fault Rules Affect Your Claim in Pennsylvania

Pennsylvania reduces a recovery by the injured person's share of fault and bars recovery if that share is greater than the combined fault of the defendants. Pennsylvania also has a statute often called the Fair Share Act, which in general terms limits how much a defendant below a fault threshold can be made to pay beyond their own share, with exceptions. The effect is that how fault is divided among defendants can change who can be pursued for what.

Hypothetical illustration

Invented numbers for arithmetic only. A claim valued at 70,000 before fault would be 49,000 at 30 percent fault and 35,000 at 50 percent. Above 50 percent fault it would be barred. Evidence that limits the injured person's share therefore protects most of the claim's value.

For a state where the choice of auto coverage also matters, compare New Jersey, and for how deadlines and notice periods look across states, see the 50-state statute of limitations table.
