Negligence: Duty, Breach, Causation, and Damages

A store employee sees a drink spill in an aisle, leaves it there without a warning sign, and a customer slips and breaks a wrist. The key questions are not simply whether an accident happened or whether someone was sued. Ask what duty applied, whether the store failed to meet it, whether that failure caused the fall, and whether the customer suffered a legally recognized injury. If a liability claim follows, the policy then raises a separate question: does its coverage apply to the insured, the event, and the claimed damages?

Negligence is a basic liability concept in property and casualty insurance because many liability claims allege that an insured failed to use reasonable care. It helps explain why an insured may be legally responsible for bodily injury or property damage. It does not, by itself, answer whether the insurer must pay. A court’s liability analysis and an insurer’s contract analysis are related but distinct.

The short framework

Many study materials teach four labels: duty, breach, causation, and damages. Texas Supreme Court opinions also state the common-law elements as duty, breach, and damages proximately resulting from the breach. The ideas still fit together: the final element requires harm connected to the breach. Follow the vocabulary used in your course or question, and do not omit causation or actual harm just because a source groups them under one heading.

Duty: was care legally required?

Duty asks whether the law required the defendant to act with care toward the claimant in the circumstances. It is the starting point. If no duty applies, a negligence claim generally cannot succeed even if the outcome was unfortunate. Texas Supreme Court authority describes duty as the threshold negligence question and explains that the existence and scope of a duty are generally legal questions for courts.

A duty is not the same as a moral expectation or a promise to prevent every injury. The law does not make every person an insurer of another person’s safety. The relationship between the parties, the type and foreseeability of the risk, and the circumstances can matter. A store that invites customers onto its premises presents a different setting from a stranger who happens to witness an accident across town.

Duty also has a scope. A person can owe some duties but not necessarily the specific duty alleged. Suppose a business hires a security company. The business may owe duties to visitors, but whether it must take a particular security measure depends on the law and facts. A court asks what duty applies to the particular conduct and risk, rather than declaring a vague duty to prevent all harm.

Breach: did conduct fall below reasonable care?

Breach asks whether the person failed to act as a reasonably careful person would under the circumstances, once the applicable duty is identified. The question is about conduct, not merely the outcome. A bad result can occur even when reasonable care was used; conversely, careless conduct can be a breach even if no one is ultimately injured.

Reasonable care is contextual. A driver approaching a school crossing may need to account for children and visibility. A restaurant responding to a spill may need to consider how long it has been there, whether employees knew or should have noticed it, and whether a warning or cleanup was practical. A contractor working at height may need to consider fall protection. These examples illustrate how facts inform the standard; they do not decide a real dispute.

Breach can involve an act or an omission. Speeding through a red light is an affirmative act. Failing to repair a known broken step may be an omission. In either case, the claimant still must connect the conduct to an applicable duty and resulting harm. “They could have done more” is not enough on its own; the question is whether the conduct fell below the required standard in that situation.

Causation: connect the breach to the harm

Causation asks whether the breach made a difference to the injury and whether the connection is sufficiently close under the applicable legal standard. In Texas negligence cases, proximate cause includes cause in fact and foreseeability. At a basic level, cause in fact asks whether the conduct was a substantial factor in bringing about the harm and whether the harm would have occurred without it. Foreseeability asks whether a person of ordinary intelligence should have anticipated the danger created by the conduct.

Return to the spill. If the customer slips on the liquid that the employee left on the floor, the facts may support a causal connection. If the customer trips over a loose shoelace in another part of the store, the spill may have nothing to do with the injury. If a warning cone had been placed and the customer ignored it, that fact may affect how responsibility is evaluated. Causation is about the relationship between the alleged failure and the particular harm, not just whether both happened on the same day.

More than one cause can contribute to an injury. A driver may be speeding while another driver makes an unsafe turn. A wet floor and a customer’s inattention may both be relevant to a fall. The fact that one person contributed does not necessarily erase the role of another. The evidence must support the causal link; timing alone or a guess about what might have happened is not enough.

This page keeps causation at the negligence level. Insurance coverage may use separate causation language to determine whether an event or loss falls within the policy. Do not transfer a rule from one analysis to the other without reading the policy and the facts. A more detailed treatment of insurance proximate cause belongs in the separate proximate-cause article.

Damages: identify actual harm

Damages are the harm for which the claimant seeks recovery. Negligent conduct without injury or loss may create a safety concern, but a negligence claim generally requires damages proximately resulting from the breach. Depending on the claim and governing law, examples can include bodily injury, medical expenses, lost income, damage to tangible property, or other legally recognized losses.

Keep the injury and the evidence distinct. A person who nearly slips but catches a railing may have experienced a dangerous event, yet the facts may not show compensable injury. A person who falls and fractures a wrist may have medical and wage losses that can be documented. The seriousness and amount of damages are not established just by the fact that a lawsuit or insurance claim was filed.

Damages also must be connected to the alleged breach. If a claimant had a prior injury, a later incident may require evidence showing which losses relate to the incident. If a business loses revenue after a customer accident, the claimant must establish a legally sufficient connection between the accident and the claimed loss. A number written in a demand letter is a requested amount, not proof that the amount is owed.

How Texas comparative responsibility changes recovery

A claimant’s own conduct can matter when more than one party contributed to the harm. Texas Civil Practice and Remedies Code Chapter 33 uses proportionate responsibility for covered actions. Under section 33.001, a claimant may not recover damages in an action covered by the chapter if the claimant’s percentage of responsibility is greater than 50 percent. If the claimant’s percentage is 50 percent or less, the damages are reduced according to the claimant’s percentage of responsibility under section 33.012, subject to the statute’s terms and applicability.

Example: a jury determines that a covered negligence claim has $40,000 in damages and assigns 25% responsibility to the injured person. A simplified proportionate-reduction calculation leaves $30,000 before other applicable issues, limits, offsets, or rules. At 60% responsibility, section 33.001’s bar would prevent recovery in an action governed by that section. These numbers teach the basic threshold; they do not predict how a real case would be decided.

Negligence and liability insurance are separate questions

Liability insurance is designed to address certain covered legal liabilities, but the policy is a contract with its own terms. TDI explains that homeowners personal liability coverage may pay medical bills, lost wages, and other costs for people the insured is legally responsible for injuring, damage to another person’s property, and court costs if the insured is sued because of an accident. Texas auto liability coverage pays for covered injury or property damage the insured causes to others, up to the applicable limits.

A commercial general liability policy also has its own scope, definitions, conditions, and exclusions. TDI’s CGL overview, for example, describes exclusions involving damage to the insured’s own work or product, certain contractual liability, and pollution, while emphasizing that coverage varies and policy wording should be reviewed. This is why “the insured was negligent” is not a complete coverage analysis.

1. First, evaluate potential legal responsibility: duty, breach, causation, damages, and any comparative responsibility issue.
2. Separately, read the policy: who qualifies as an insured, what bodily injury or property damage is alleged, when and where it occurred, and what coverage part may apply.
3. Check the applicable coverage trigger and policy terms, including exclusions, conditions, limits, and any endorsements.
4. Consider the insurer’s claim-handling and defense obligations under the actual contract and applicable law; do not infer them from the word negligence alone.

For example, a customer alleges that a contractor negligently installed a water heater and that a leak damaged the customer’s furniture. The legal questions include whether the contractor owed a duty, whether installation fell below the standard of care, whether that failure caused the leak, and what losses resulted. The policy questions include whether the contractor is an insured, whether the alleged damage meets the policy’s definition of property damage, whether the relevant work or product exclusion applies, and what limits or conditions govern. The negligence label alone does not decide those contract questions.

Negligence compared with nearby concepts

A broken stair can be a hazard. A property manager might or might not have acted negligently depending on the duty, knowledge, response, and circumstances. A visitor’s fall is an accident. The visitor must still show the required connection and damages for a negligence claim. Any insurance policy must then be analyzed on its own language. Using these labels precisely keeps an exam answer from jumping between risk, fault, and coverage.

A worked example from allegation to coverage review

A delivery company leaves a cart partly across a store aisle. A shopper turns the corner, trips over it, injures a shoulder, and alleges that both the store and delivery company were careless. Work through the issues in order.

1. Duty: determine whether each party owed the shopper a duty of care in the circumstances. The store’s relationship with customers and the delivery company’s activity on the premises may raise different duty questions.
2. Breach: ask whether placing or leaving the cart in that location, failing to move it, or failing to warn fell below reasonable care based on what each party knew and could reasonably do.
3. Causation: ask whether the cart’s position contributed to the trip and whether the injury followed from that event. Evidence such as photographs, video, witness accounts, and medical records may matter.
4. Damages: identify supported losses, such as treatment expense or missed work, and distinguish them from amounts that are only alleged.
5. Comparative responsibility: consider whether the shopper or another actor also contributed. If the Texas proportionate-responsibility statute applies, the assigned percentages affect recovery under Chapter 33.
6. Insurance: examine each potentially relevant policy for insured status, coverage grant, timing, exclusions, defense terms, limits, and other conditions. The store’s policy and delivery company’s policy may not respond in the same way.

This sequence is useful because each stage answers a different question. An insurer can investigate while legal fault is disputed. A claim may settle without a court finding negligence. A court may find liability but the policy may cover only part of the resulting amount, or may not cover a particular item of damage. The actual result depends on evidence, law, and contract terms.

Common exam traps

• Treating an injury as automatic proof of negligence.
• Skipping duty and assuming everyone owes every other person a duty in every setting.
• Calling conduct a breach without identifying the circumstances or standard of care.
• Assuming that a safety-rule violation by itself proves causation and damages.
• Confusing cause in fact with mere sequence: one event happening before another does not prove it caused it.
• Ignoring damages and treating a near miss or allegation as an established loss.
• Assuming the claimant’s carelessness always eliminates recovery; Texas Chapter 33 generally bars recovery only when the claimant’s responsibility is greater than 50%, when that statute applies.
• Treating comparative responsibility as an insurance deductible or limit calculation.
• Assuming every negligent act is covered simply because the insured bought liability insurance.
• Assuming a policy’s coverage trigger and exclusions are decided by the tort-law meaning of negligence.
• Treating a demand, lawsuit, or claim notice as proof that the insured is legally liable.
• Confusing property coverage for the insured’s own things with liability coverage for injury or damage to others.

Quick review

• Duty: what care did the law require in this relationship and situation?
• Breach: what conduct failed to meet that care?
• Causation: how did that failure bring about the particular harm?
• Damages: what actual, legally recognized loss resulted?
• Comparative responsibility: did the claimant or another actor contribute, and what statutory rule applies?
• Insurance: which policy wording, coverage part, exclusions, limits, and conditions govern?

Frequently asked questions

What are the elements of negligence?

A common study framework lists duty, breach, causation, and damages. Texas Supreme Court cases often express the elements as duty, breach, and damages proximately resulting from the breach; causation is included in that final element.

Does an accident prove negligence?

No. An accident may happen even when everyone used reasonable care. A negligence claim requires the applicable duty, breach, legally sufficient causation, and damages.

Is negligence the same as proximate cause?

No. Negligence is the broader claim framework. Proximate cause is part of the causation analysis connecting a breach to harm. Insurance policies may use separate cause-of-loss wording for coverage.

Does negligence automatically mean the insurer must pay?

No. Negligence concerns legal responsibility. Insurance payment depends on the policy’s coverage grant, insured status, exclusions, conditions, limits, and the facts.

How does Texas comparative responsibility work?

Under Texas Civil Practice and Remedies Code section 33.001, a claimant whose responsibility is greater than 50% cannot recover damages in an action covered by the chapter. If responsibility is 50% or less, damages are generally reduced in proportion to that responsibility, subject to statutory terms.

Can more than one person be negligent?

Yes. Multiple people’s conduct may contribute to one injury. The facts and applicable law determine which actors are responsible and how responsibility is allocated.

Does a liability policy cover intentional harm?

Many policies restrict or exclude coverage for intentional conduct, but the exact wording and facts matter. Do not infer the result from the negligence framework alone.
