Tort law is the branch of civil law that lets a person harmed by someone else’s conduct sue for money damages. Unlike a criminal case, where the government prosecutes and the goal is punishment, a tort claim is brought by the injured party and the goal is compensation. The person who caused the harm pays for the losses that followed, and the prospect of that financial responsibility is meant to discourage unsafe conduct in the first place. Claims generally fall into one of three categories depending on how the defendant behaved, and the category decides what you have to prove and what the other side can argue back.
The Three Categories of Tort Claims
Every tort claim sorts into one of three groups based on the defendant’s state of mind and conduct.
Intentional torts involve someone who acted on purpose. The law focuses on whether the defendant intended the act, not necessarily the exact injury that followed. If you swing to shove someone and break their nose instead, the intent behind the swing is enough.
Negligence covers accidental harm caused by carelessness.1Legal Information Institute. Negligence The defendant did not mean to hurt anyone but failed to act with the caution a reasonable person would use in the same situation. This is the basis for most tort lawsuits: car crashes, slip-and-falls, medical errors, and the like.
Strict liability sets fault aside. For certain inherently dangerous activities and defective products, the defendant pays for the resulting harm regardless of how careful they were. The idea is that whoever profits from the risky activity should carry the cost when the risk materializes.
What Counts as an Intentional Tort
Intentional torts cover a range of deliberate wrongs. The ones most often litigated share one thread: the defendant chose to act in a way that invaded someone else’s rights.
- Battery is intentionally touching another person in a harmful or offensive way without consent. Physical injury is not required; unwanted contact a reasonable person would find offensive can qualify.
- Assault is placing someone in reasonable fear of imminent harmful or offensive contact. You do not have to actually touch the person. A raised fist or a pointed weapon is enough if the victim genuinely fears being struck.
- False imprisonment is intentionally confining or restraining someone without legal authority. The restraint can be physical, but threats or abuse of authority count too, as long as the person has no reasonable means of escape.
- Intentional infliction of emotional distress involves conduct so extreme and outrageous that it causes severe emotional harm. Courts set a high bar. The behavior must go well beyond rudeness or insults.2Legal Information Institute. Intentional Infliction of Emotional Distress
Motive matters less than the choice to act. A prank gone wrong can be just as actionable as a malicious attack, because the law looks at whether the defendant intended the physical act that caused the harm.
Defamation sits in a category of its own, blending intentional and negligent elements. A claim requires a false statement of fact communicated to someone other than the plaintiff, fault on the speaker’s part, and resulting harm to reputation.3Legal Information Institute. Defamation Public figures have to clear a higher bar than private individuals, because they must prove the statement was made with knowledge of its falsity or reckless disregard for the truth.
The Four Elements of a Negligence Claim
Negligence claims rise or fall on four elements. Miss one and the case fails, no matter how badly you were hurt. The Restatement (Third) of Torts frames them as a failure to exercise reasonable care, factual causation, physical harm, and harm within the scope of liability.4Open Casebook. Third Restatement Section 6
Duty and Breach
The first question is whether the defendant owed you a duty of care. In most situations, everyone owes a basic obligation to act with the caution a reasonable person would use under the same circumstances.1Legal Information Institute. Negligence A driver owes other motorists and pedestrians a duty to follow traffic laws. A store owner owes customers a duty to keep walkways clear of hazards. Breach is the behavior that falls short of that standard. The question is objective. Not what this particular defendant thought was safe, but what a prudent person in the same position would have done.
Causation
Carelessness alone is not enough. You have to connect it to your specific injury, and that connection has two parts. Cause-in-fact asks whether the injury would have happened if the defendant had acted carefully. This is often called the but-for test.5Tort Law: A 21st-Century Approach. Negligence: Causation If you would have been hurt anyway, the defendant’s carelessness was not the factual cause.
Proximate cause, which the Restatement (Third) calls scope of liability, limits responsibility to harms that were reasonably foreseeable. Courts use this to draw a line, so defendants are not held responsible for freak chain reactions nobody could have predicted.
Actual Damages
You must have suffered a real, demonstrable loss. Close calls and near-misses do not support a negligence claim, no matter how reckless the defendant was. Medical records, repair bills, and wage statements are the backbone of proving damages.
The plaintiff carries the burden of proving every element by a preponderance of the evidence, which means showing each element is more likely true than not.6Legal Information Institute. Preponderance of the Evidence That is a lower threshold than the beyond-a-reasonable-doubt standard in criminal cases, but it still requires concrete proof on every element.
When the Standard of Care Shifts
Negligence Per Se
Sometimes breach is established automatically by a statutory violation. This is called negligence per se. If a defendant violates a law designed to prevent the type of harm that occurred, and the injured person belongs to the class the law was meant to protect, courts treat the violation itself as proof of negligence.7Legal Information Institute. Negligence Per Se The plaintiff still has to prove causation and damages, but the argument over whether the defendant was reasonable is essentially over.
A driver who runs a red light and hits a pedestrian is the standard illustration. Traffic laws protect other road users from collisions, the pedestrian is exactly the person the law protects, and the collision is exactly the harm the law aims to prevent.
Professional Standard of Care
The reasonable-person test shifts when the defendant is a professional, such as a doctor, lawyer, or architect. Professionals are held to the standard of a reasonably competent practitioner in their field. Most states apply a national standard, meaning the question is whether the professional provided care at the level recognized as acceptable by similar practitioners nationwide. A few jurisdictions still use a locality-based standard for general practitioners while applying the national standard for specialists.
This higher standard is what drives medical and legal malpractice claims. Proving breach almost always requires expert testimony from another professional in the same field who can explain the accepted standard and how the defendant fell short. Without that expert, these cases rarely survive.
Strict Liability Situations
Strict liability removes the fault question entirely. The plaintiff does not need to prove carelessness or intent. The occurrence of the injury in certain categories is enough.
Defective Products
When a manufacturing or design flaw makes a product unreasonably dangerous, the manufacturer and everyone in the distribution chain can be held strictly liable for resulting injuries.8Legal Information Institute. Manufacturing Defect A manufacturing defect means a specific unit departed from its intended design. A design defect means the entire product line is dangerous because of a flaw in the blueprint. Failure-to-warn defects cover products that lack adequate instructions or safety warnings. The plaintiff does not need to show the manufacturer was careless in quality control; the defect and the resulting injury are enough.
Abnormally Dangerous Activities
Certain activities trigger strict liability because they create a significant risk of serious harm even when everyone involved exercises reasonable care, and they are not activities in common use.9Open Casebook. Restatement Third – Abnormally Dangerous Activities The classic examples are using explosives for demolition and storing large quantities of hazardous chemicals.10Legal Information Institute. Ultrahazardous Activity
Animal Injuries
Owners of wild animals are strictly liable for any injuries those animals cause, regardless of how carefully the animal was restrained. For domestic animals, strict liability applies when the owner knows or should know the animal has dangerous tendencies beyond what is normal for its species. A dog that has bitten before, for instance, may trigger strict liability for the owner on a later bite, because the owner is now on notice of the animal’s dangerous propensity.11Open Casebook. Restatement Third of Torts on Strict Liability for Harm Caused by Animals
When Someone Else Has to Pay
Liability does not always fall on the person who physically caused the harm. Under respondeat superior, an employer can be held liable for an employee’s wrongful acts committed within the scope of employment.12Legal Information Institute. Respondeat Superior A delivery driver who causes a crash while making deliveries puts the employer on the hook, because the driver was acting in furtherance of the employer’s business.
The critical line is between employees and independent contractors. Employers are generally not liable for the torts of independent contractors, because the hiring party does not control how the work gets done. Courts weigh factors like control over the manner and means of the work, who provides tools and workspace, how the worker is paid, and how long the engagement lasts. The more control the hiring party exercises, the more likely the worker is treated as an employee for liability purposes.12Legal Information Institute. Respondeat Superior
When multiple defendants are responsible for the same injury, joint and several liability may apply. Each defendant is independently liable for the full amount of damages. If one defendant cannot pay, the plaintiff can collect the entire judgment from any other defendant who can.13Legal Information Institute. Joint and Several Liability The defendant who overpays can then seek contribution from the others. Many states have modified this rule through tort reform, shifting toward proportional liability where each defendant pays only their percentage of fault.
What You Can Recover
The goal of tort damages is to put you back in the financial position you would have been in if the injury had never happened. That is an imperfect exercise, especially for catastrophic injuries, but it drives how courts calculate awards.
Economic Damages
Economic damages, sometimes called special damages, cover losses with a verifiable dollar figure. Hospital bills, surgery costs, physical therapy, prescription medications, and lost wages are the common categories. Future losses count too. If an injury permanently limits your earning capacity or requires ongoing medical treatment, an expert can project those costs and include them in the claim. The figures are built from documentation like medical bills, wage records, and employment data.
Non-Economic Damages
Non-economic damages compensate for losses that are real but harder to quantify: physical pain, emotional distress, and the diminished ability to enjoy life after a serious injury. Juries have broad discretion in setting these amounts, and there is no standard formula. Attorneys sometimes use a multiplier approach, calculating non-economic damages as some multiple of the economic losses, but that is a negotiation tool, not a legal requirement.
A number of states cap non-economic damages, particularly in medical malpractice cases. Caps vary widely. Some states impose a fixed ceiling, others apply none at all. The specifics depend on your jurisdiction.
Punitive Damages
Punitive damages exist to punish the defendant and deter similar conduct, not to compensate the plaintiff. Courts reserve them for conduct that goes beyond ordinary negligence into territory involving malice, fraud, or reckless indifference to safety.14Legal Information Institute. Punitive Damages The U.S. Supreme Court has held that few punitive awards exceeding a single-digit ratio to compensatory damages will satisfy due process.15Legal Information Institute. State Farm Mutual Automobile Insurance Co v Campbell
Mitigation and the Collateral Source Rule
Injured plaintiffs have an obligation to take reasonable steps to minimize their losses. If you refuse medical treatment that would have reduced the severity of your injury, a court can cut your damages by the amount you could have avoided.16Legal Information Institute. Duty to Mitigate The defendant carries the burden of proving the failure to mitigate, and only reasonable efforts are expected. Nobody has to undergo a risky surgery just to protect the defendant’s wallet.
Under the collateral source rule, a defendant generally cannot reduce the damages owed just because your health insurance or workers’ compensation already covered some of the costs. The reasoning is that the defendant should not benefit from the plaintiff’s foresight in obtaining insurance. The rule also keeps the jury from learning that a third party already compensated the plaintiff, since that information could unfairly reduce the award.17Legal Information Institute. Collateral Source Rule A growing number of states have modified or partially abolished the rule through tort reform, especially in medical malpractice cases.
Defenses That Reduce or Eliminate Liability
Even when the plaintiff can prove every element, the defendant may have defenses that cut or kill the claim. The strength of those defenses varies significantly by state.
Comparative and Contributory Negligence
The most impactful defense in negligence cases is that the plaintiff’s own carelessness contributed to the injury. How much that matters depends on which system your state follows.
A majority of states use modified comparative negligence. Your damages are reduced by your percentage of fault, but only if your fault stays below a threshold. Some states set that bar at 50 percent and others at 51 percent. Meet or cross the threshold and you recover nothing.18Legal Information Institute. Comparative Negligence
Roughly a third of states follow pure comparative negligence, which lets you recover even if you were 99 percent at fault. Your award is simply reduced by your share of the blame. So if you are 70 percent responsible for a $100,000 loss, you collect $30,000.18Legal Information Institute. Comparative Negligence
A handful of jurisdictions still follow pure contributory negligence, the older rule that bars the plaintiff from recovering anything if they bear even one percent of the fault. This is the harshest system for plaintiffs and applies in only about five jurisdictions. Even minor carelessness can destroy an otherwise strong claim there.
Assumption of Risk
A defendant may argue that the plaintiff knowingly and voluntarily accepted the risk that caused the injury. The defense has two forms. Express assumption of risk occurs when you sign a waiver or release before participating in an activity, like a skydiving consent form. Implied assumption of risk is inferred from your conduct. Sit near the field at a baseball game, and a court may find you accepted the foreseeable risk of being hit by a foul ball.
The defense has limits. It does not shield defendants whose reckless or intentional conduct exceeds the risks the plaintiff accepted, and it does not cover hidden or unforeseeable dangers the plaintiff had no way to anticipate.
Government Immunity
Suing a government entity comes with special hurdles. The federal government can be sued for tort claims only under the Federal Tort Claims Act (FTCA), which waives sovereign immunity but includes important exceptions. The broadest is the discretionary function exception, which preserves immunity for government decisions involving judgment or policy choices.19Office of the Law Revision Counsel. 28 USC 2680 – Exceptions The FTCA also excludes claims based on certain intentional torts like misrepresentation and interference with contract, although a carve-out for law enforcement officers allows claims for assault, battery, and false arrest against federal agents. State and local governments have their own immunity frameworks, and most require you to file an administrative claim before suing.
The Filing Deadline
Every tort claim has a filing deadline, and missing it almost always kills the case regardless of how strong the facts are. For most personal injury claims, the filing window falls in the range of two to three years, though the exact deadline depends on the type of tort and the jurisdiction. Some intentional torts and property damage claims have different deadlines, so checking the specific rules early is critical.
The clock generally starts on the date of the injury. A significant exception exists for injuries that are not immediately apparent. The discovery rule delays the start of the limitations period until the plaintiff knew or should have known about the injury and its potential cause. This matters most in cases like medical malpractice, where a surgical error might not produce symptoms for months or years, or toxic exposure cases, where harm accumulates slowly. The discovery rule is not unlimited; it requires reasonable diligence in investigating potential injuries once warning signs appear.
Government claims have even shorter deadlines. Under the FTCA, administrative claims against the federal government must be filed within two years of the date the claim accrues.19Office of the Law Revision Counsel. 28 USC 2680 – Exceptions Many state and local governments impose notice requirements of six months or less. This is where more claims die than people realize. The substantive law may be on your side, but if you missed the filing window, it does not matter.
How You Pay a Tort Lawyer
Most tort plaintiffs hire attorneys on a contingency fee basis, meaning the lawyer gets paid only if you win or settle. The attorney’s fee typically runs between a third and 40 percent of the total recovery. On a $100,000 settlement, that is $33,000 to $40,000 going to the attorney before you see a dollar. Case expenses, including filing fees, expert witness costs, and deposition transcripts, are usually deducted separately.
The final distribution comes through a settlement statement that itemizes every deduction: attorney fees, litigation costs, and any outstanding medical liens from providers who treated you on credit. For many plaintiffs, the net amount is significantly less than the headline settlement figure. The tradeoff is access. Contingency arrangements let people who could never afford hourly legal rates pursue claims that would otherwise go uncompensated.
