Injury Law Authority - Personal Injury Law Authority Reference
Personal injury law governs the legal rights of individuals who suffer physical, psychological, or financial harm caused by another party's negligent, reckless, or intentional conduct. This reference page covers the structural framework of personal injury claims under US tort law, including the elements required to establish liability, the procedural phases of a civil claim, and the classification boundaries that distinguish personal injury from adjacent legal areas. The page also maps the network of state-level and subject-matter legal reference resources that extend this framework across all 50 states.
Definition and scope
Personal injury law is a branch of civil tort law that assigns liability when one party's conduct causes legally cognizable harm to another. The governing standard in the majority of US jurisdictions derives from the common law duty-breach-causation-damages framework, codified and modified by state legislatures and interpreted through appellate decisions. At the federal level, the Federal Rules of Civil Procedure (FRCP) establish procedural baselines for personal injury actions filed in federal court, while substantive law remains state-specific under the Erie doctrine.
The scope of personal injury law encompasses four primary claim categories:
- Negligence — the dominant theory, requiring proof that a defendant owed a duty of care, breached that duty, and proximately caused damages.
- Strict liability — applied in product liability and animal attack contexts, where fault need not be proven; liability attaches to the act or product itself.
- Intentional torts — assault, battery, false imprisonment, and intentional infliction of emotional distress, where the defendant's deliberate conduct caused harm.
- Negligence per se — liability established when a defendant violates a statute designed to protect a class of persons, and that violation causes harm within that class.
The Restatement (Third) of Torts: Liability for Physical and Emotional Harm, published by the American Law Institute (ALI), provides the most widely cited secondary authority for defining duty, breach, and causation standards across US jurisdictions.
For a grounding in the broader procedural context, the how the US legal system works conceptual overview resource on this site explains the structural relationship between civil and criminal courts, appellate review, and federalism principles that shape personal injury adjudication.
State-specific scope variations are substantial. Alabama Legal Services Authority addresses tort law under Alabama's contributory negligence bar — one of 4 remaining US jurisdictions that applies pure contributory negligence, meaning any plaintiff fault defeats recovery entirely. Alaska Legal Services Authority covers Alaska's modified comparative fault system under AS 09.17.060, which allows recovery only when the plaintiff's fault does not exceed the defendant's. Arizona Legal Services Authority references Arizona's pure comparative fault rule, codified at A.R.S. § 12-2505, permitting recovery regardless of plaintiff's percentage of fault.
How it works
A personal injury claim advances through a structured sequence of phases that mirror the broader civil litigation process. The process framework for the US legal system resource provides the procedural scaffolding within which these phases operate.
Phase 1 — Incident documentation and preservation
Immediately following an injury-causing event, the injured party must preserve evidence: photographs, incident reports, witness contact information, and medical records. Spoliation of evidence — the negligent or intentional destruction of relevant material — can result in adverse inference jury instructions under most state rules of evidence.
Phase 2 — Medical treatment and damage quantification
Damages in personal injury cases fall into two categories:
- Economic damages: Medical expenses, lost wages, and future lost earning capacity — all subject to documentary proof.
- Non-economic damages: Pain and suffering, loss of consortium, and emotional distress — subject to caps in 33 states, according to data compiled by the National Conference of State Legislatures (NCSL).
Phase 3 — Pre-litigation negotiation
The majority of personal injury claims resolve before trial through direct negotiation or structured settlement. The insurer for the at-fault party typically leads this process. Arkansas Legal Services Authority details Arkansas-specific bad faith insurance statutes (Ark. Code Ann. § 23-79-208) that govern insurer conduct during pre-litigation negotiations.
Phase 4 — Filing and service
If negotiation fails, the plaintiff files a complaint in the appropriate court. Statutes of limitations govern filing deadlines and vary by state and claim type — typically ranging from 1 to 6 years for personal injury, with 2 years being the most common standard for negligence claims. California Legal Services Authority covers California's 2-year statute under CCP § 335.1, along with tolling provisions for minors and delayed discovery. Colorado Legal Services Authority references Colorado's 3-year personal injury limitation under C.R.S. § 13-80-101.
Phase 5 — Discovery
Both parties exchange evidence through interrogatories, depositions, requests for production, and independent medical examinations (IMEs). Expert witnesses — physicians, accident reconstructionists, economists — are disclosed and deposed during this phase.
Phase 6 — Trial or resolution
Fewer than 5% of personal injury cases filed in US courts proceed to verdict, according to data from the Bureau of Justice Statistics (BJS). Resolution pathways include jury verdict, bench trial, mediation, arbitration, or structured settlement.
Connecticut Legal Services Authority addresses Connecticut's offer of judgment rule under CGS § 52-192a, which creates fee-shifting incentives for pre-trial settlement. Delaware Legal Services Authority covers Superior Court procedural rules for personal injury filings in Delaware's court of general jurisdiction. Florida Legal Services Authority documents Florida's 2023 tort reform legislation (HB 837), which reduced the statute of limitations from 4 years to 2 years and modified comparative fault thresholds.

Common scenarios
Personal injury claims arise in predictable factual patterns, each with distinct liability and damages frameworks. The personal injury authority and national personal injury authority resources catalog these patterns in structured reference format.
Motor vehicle collisions
Motor vehicle accidents generate the largest volume of personal injury claims in the US. Liability turns on traffic statute violations, black box data, witness testimony, and accident reconstruction. No-fault insurance states — including Florida, Michigan, New York, and Pennsylvania — require injured parties to first exhaust personal injury protection (PIP) benefits before pursuing tort claims. Georgia Legal Services Authority covers Georgia's at-fault insurance system and the minimum liability coverage requirements under O.C.G.A. § 33-7-11. Hawaii Legal Services Authority addresses Hawaii's no-fault PIP system under HRS § 431:10C-103.
The national accident authority and accident law authority resources address accident-specific liability frameworks, including rear-end collision presumptions and intersection fault allocation rules.
Premises liability
Property owners owe duties of care to entrants that vary by the visitor's legal status: invitees receive the highest duty, licensees an intermediate duty, and trespassers a limited duty in most jurisdictions. Idaho Legal Services Authority covers Idaho's unified duty standard under Rowland v. Christian-influenced doctrine. Illinois Legal Services Authority references the Premises Liability Act (740 ILCS 130), which abolished the invitee/licensee distinction for Illinois landowners.
Medical malpractice
Medical malpractice is a specialized personal injury subcategory requiring expert testimony to establish the applicable standard of care and deviation therefrom. The medical malpractice authority, malpractice authority, and national medical malpractice authority resources provide subject-specific reference coverage. Indiana Legal Services Authority covers Indiana's Medical Malpractice Act (IC 34-18), which caps total recovery at $1.8 million per occurrence and requires claims to pass through a medical review panel before trial (Indiana Department of Insurance). Iowa Legal Services Authority references Iowa's expert witness certification requirements under Iowa R. Civ. P. 1.700.
Workplace injuries
Workers' compensation systems in all 50 states create an exclusive remedy bar for most on-the-job injuries, channeling claims away from tort court. However, third-party tort liability — against equipment manufacturers, property owners, or contractors — remains available alongside workers' compensation. Kansas Legal Services Authority covers the Kansas Workers Compensation Act (K.S.A. 44-501) and its interaction with third-party tort claims. Kentucky Legal Services Authority addresses KRS Chapter 342 workers' compensation exclusivity provisions and the intentional tort exception recognized by Kentucky courts.
The national labor authority resource covers the intersection of
