Personal Injury & Negligence Law in PA

If someone's carelessness caused your injury, Pennsylvania law lets you sue for damages. But you have to prove four specific elements, and the comparative negligence rules can reduce or eliminate your recovery depending on your share of fault. Here is how it works.

This page explains the legal framework behind an injury lawsuit. For practical guidance after an accident, including how insurers value claims, visit our personal injury practice area.

The Four Elements of Negligence

To win a negligence claim in Pennsylvania, you must prove all four of these elements by a preponderance of the evidence (more likely than not). Failure to prove any element defeats the claim.

1. Duty: The defendant owed a legal duty to act with reasonable care toward the plaintiff. In most situations, everyone has a general duty to avoid carelessly injuring others, and the scope of that duty depends on the relationship between the parties. Drivers have a duty to obey traffic laws; homeowners have a duty to maintain safe premises for invited guests; healthcare providers have a duty to deliver competent medical care; property owners have a duty to warn of known hazards. Pennsylvania recognizes no duty in some situations (e.g., bystanders generally have no duty to rescue a drowning stranger).

2. Breach: The defendant breached that duty by failing to exercise reasonable care. The "reasonable person" standard applies: would a reasonable person in the defendant's position have acted differently? Breach can be proved by direct evidence (the defendant admits carelessness), circumstantial evidence (the defendant violated a statute or safety regulation), or the doctrine of res ipsa loquitur ("the thing speaks for itself", the accident would not have happened without negligence, such as a ladder rung breaking during normal use).

3. Causation: The defendant's breach must have actually caused your injury (actual cause) and must have been a substantial factor in bringing about the injury (proximate cause). You cannot recover if the defendant's negligence merely happened to occur before your injury. Causation requires a direct chain of events between the breach and your damage. If a store employee spills water and creates a dangerous condition, but you are injured hours later on a different floor, causation may fail.

4. Damages: You must have suffered actual, quantifiable injury or loss. This includes economic damages (medical bills, lost wages, property damage) and non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life). Without damages, even proven negligence yields no recovery.

Comparative Negligence Under 42 Pa.C.S. § 7102

Pennsylvania is a "modified comparative negligence" jurisdiction, governed by 42 Pa.C.S. § 7102. Under this rule, a plaintiff may recover damages even if partially at fault for the injury, but with significant restrictions.

The core rule: A plaintiff is barred from recovery if more than 50% responsible for the injury. A plaintiff who is exactly 50% at fault may still recover, with damages reduced proportionally. If the plaintiff is 50% or less at fault, recovery is permitted, but damages are reduced by the plaintiff's percentage of fault. For example:

• If you are 25% at fault in a car accident and your damages are $100,000, you may recover $75,000 (reduced by your 25% share of responsibility).
• If you are 30% at fault, you recover 70% of damages.
• If you are 51% at fault, you recover nothing (barred entirely).

How fault is allocated between you and the defendant, or among multiple defendants, directly determines your recovery. Defendants and their insurers will aggressively argue that you bear a large percentage of fault to reduce their payment exposure.

Joint and several liability: When multiple defendants contribute to your injury, Pennsylvania's Fair Share Act sets the default. Under 42 Pa.C.S. § 7102(a.1)(2), each defendant is generally liable only for their own proportionate share of fault (several liability), not the full amount of your damages. Full-amount (joint and several) liability is the exception. It applies only in the limited circumstances listed in § 7102(a.1)(3), chiefly where a defendant is held at least 60% at fault, or in cases of intentional misrepresentation, intentional torts, and certain hazardous-substance releases. If Defendant A is 40% at fault, Defendant A can be held liable for only their 40% share. If Defendant A is 60% or more at fault, they may be held liable for 100% of your damages even if there are other defendants.

Statute of Limitations: 2 Years

Under 42 Pa.C.S. § 5524, negligence actions must be filed within two years from the date of the injury . This applies to personal injury claims arising from negligence, premises liability, auto accidents, and most other tort actions. Missing this deadline generally results in complete loss of your right to sue. In limited circumstances the "discovery rule" can delay the start of the two-year period until you knew, or through reasonable diligence should have known, of your injury and its cause; do not assume it applies to your case.

Critical deadlines:

• Two years from the date the cause of action accrues to file suit
• The discovery rule may delay accrual until you knew, or reasonably should have known, of the injury and its cause; it is applied narrowly and you bear the burden of showing it applies
• The statute is strictly enforced; do not count on an extension
• Tolling applies only in limited circumstances. Minority tolls the period (a minor has the full two years after turning 18); under 42 Pa.C.S. § 5533(a), insanity and imprisonment do not extend the deadline

If you have been injured because of someone else's carelessness, talk to an attorney immediately . Do not rely on informal settlement negotiations or insurance company offers to extend your deadline.

Types of Damages: Economic, Non-Economic, and Punitive

Economic damages: These are objectively measurable, out-of-pocket losses. They include:

• Medical and healthcare expenses (past and future)
• Lost wages and loss of earning capacity
• Property damage (vehicle repair or replacement)
• Rehabilitation and therapy costs
• In cases of permanent disability, lifetime care costs

Non-economic damages: These compensate intangible losses resulting from your injury. They include:

• Pain and suffering (physical pain experienced and expected to be experienced)
• Emotional distress and mental anguish
• Loss of enjoyment of life (inability to participate in hobbies, activities, or relationships)
• Disfigurement or scarring
• Loss of society or companionship (in cases of severe injury or death)

Punitive damages: These are awarded to punish the defendant for egregious conduct, not merely to compensate you. Under Pennsylvania common law, punitive damages may be awarded only for outrageous conduct, meaning acts done with evil motive or reckless indifference to the rights of others, a much higher bar than simple negligence. Punitive damages are rare in ordinary personal injury cases but may apply in cases of DUI causing injury, intentional wrongdoing masked as negligence, or deliberate disregard for safety.

Joint and Several Liability Rules

When your injury results from the combined negligence of multiple parties, Pennsylvania's Fair Share Act determines who pays what. Under § 7102(a.1)(2), the basic rule is several liability: each defendant generally pays only their apportioned share of fault, not the full amount of your damages. A defendant becomes liable for the full (joint and several) amount only in the limited circumstances in § 7102(a.1)(3), chiefly being held at least 60% at fault, or in cases of intentional misrepresentation, intentional torts, or certain hazardous-substance releases.

Example: You are injured by both a defective product (manufacturer is 35% at fault) and negligent medical treatment (surgeon is 65% at fault). The surgeon, being 60% or more at fault, may be held liable for 100% of your damages. The manufacturer, being less than 60% at fault, is liable only for 35% of damages. If the surgeon is judgment-proof (no assets or insurance), you cannot pursue the manufacturer for the full amount.

This rule significantly affects settlement strategy and the distribution of responsibility among multiple defendants.

What to Do After an Injury

Immediate steps: Seek medical attention and get the injury documented professionally. Medical records establish the extent of the injury and create a record of causation. If the incident happened at a business, report it to management right away and ask that it be documented. If it was a vehicle accident, call the police and obtain the accident report number. Collect the other party's name, phone number, address, insurance information, and license plate if applicable, along with names and contact information for any witnesses. If it is safe to do so, photograph the accident location, road conditions, signage, lighting, and property damage. Save all medical bills, prescription receipts, invoices for repairs, and records of time off work, and keep a written log of your symptoms, treatment, and recovery progress.

Preserve evidence:

• Do not repair or discard damaged property until the other side has an opportunity to inspect it
• Preserve any physical evidence (defective product, etc.)
• If on someone's property, request copies of security camera footage immediately (business may delete it within days)
• Request copies of maintenance or safety records if your injury involved a hazardous condition on business premises

Dealing with insurance: Do not give a recorded statement to the other side's insurance company without consulting an attorney. You can provide factual information (who, what, when, where) but should avoid detailed discussions of causation, injury, or liability. Insurance adjusters are skilled at eliciting statements that can be used to deny or minimize your claim. Under Pennsylvania law, a material and prejudicial breach of a cooperation clause can be grounds for denying coverage, so consult an attorney before giving or refusing any recorded statement to your own insurer.

Practical: Investigation and Discovery

Once a lawsuit is filed, you will obtain discovery, the legal process of gathering evidence from the other side. Typical discovery in negligence cases includes:

• Interrogatories (written questions about the incident, injuries, medical treatment, and damages)
• Requests for production of documents (medical records, repair bills, pay stubs, photographs)
• Depositions (oral testimony under oath of the defendant, witnesses, and experts)
• Subpoenas for records held by third parties (hospitals, employers, government agencies)

The strength of your case depends heavily on the evidence available, police reports, medical records, witness testimony, photographs, and expert analysis. Early investigation and preservation of evidence strengthens your position in settlement negotiations or trial.
