A slip and fall case looks simple from the outside. Someone fell on someone else's property and got hurt. The law turns those facts into a claim only when three things come together. The property owner owed a duty of care to the injured person. The dangerous condition existed long enough that the owner knew about it or should have known about it. And the injured person did not bear a share of fault that exceeds what the state allows. This post walks through premises liability as the doctrine behind the claim, comparative negligence as the rule that splits fault, and the notice rules that decide whether the owner had time to act.
What premises liability actually does
Premises liability is the body of law that imposes duties on property owners and occupiers to keep their premises reasonably safe. The duty owed depends on the status of the person on the property. The common law categories are still used in most states.
Invitee. A person on the property for the owner's business benefit. Store customers and hotel guests are the classic examples. Owners owe invitees the highest duty: to inspect for hazards and to warn or repair.
Licensee. A person on the property with permission for the licensee's own purpose. Social guests are the classic example. Owners owe licensees a duty to warn of known hazards but generally not a duty to inspect.
Trespasser. A person on the property without permission. Owners owe trespassers a more limited duty, usually to avoid willful or wanton harm, with special rules for child trespassers under the attractive nuisance doctrine.
Some states have abandoned the three-tier system and apply a single duty of reasonable care to everyone lawfully on the property. The trend has been mixed. The label matters because it controls how the duty is described to the jury.
What the plaintiff has to prove
A slip and fall plaintiff must prove four elements. Each requires evidence, not just the fact of the fall.
Duty. The owner owed a duty to the plaintiff based on the plaintiff's status and the relevant state rule.
Breach. The owner failed to meet that duty. The condition was unreasonably dangerous and the owner did not warn, repair, or take other reasonable action.
Causation. The breach caused the plaintiff's injury. The slip was the result of the dangerous condition, not an unrelated factor.
Damages. The plaintiff suffered actual harm: medical expenses, lost wages, pain and suffering, and other recoverable categories under state law.
The fact of a fall does not by itself establish breach. The plaintiff has to identify the hazard and show it was unreasonable.
The notice problem
The central battleground in most slip and fall cases is notice. The plaintiff has to prove that the owner either created the dangerous condition, knew it existed and did not act, or should have known it existed because it had been there long enough for a reasonable inspection to find it.
- Actual notice. Someone working for the owner saw the hazard, was told about it, or otherwise knew it existed. The clearest version of notice.
- Constructive notice. The hazard existed long enough that a reasonably attentive owner should have discovered it. Constructive notice is proven with evidence about how long the condition was present, how visible it was, and what the owner's inspection routine should have been.
- Mode of operation. Some states allow plaintiffs to bypass the notice requirement in self-service settings where the business should anticipate that customers will create hazards, such as a salad bar or a self-serve drink station. The doctrine applies narrowly.
Notice evidence is often the difference between a case that settles and a case that does not. Surveillance video showing a hazard for 45 minutes before the fall is strong constructive notice. The absence of any timing evidence is weak notice. The plaintiff should preserve evidence quickly and demand preservation of the defendant's video before it is overwritten.
Comparative negligence and how fault splits
Most states have moved from contributory negligence, where any fault by the plaintiff barred recovery, to comparative negligence, where fault is split. The variations matter.
- Pure comparative negligence. The plaintiff recovers the percentage of damages attributable to the defendant. A plaintiff 80 percent at fault still recovers 20 percent of damages.
- Modified comparative negligence with a 50 percent bar. The plaintiff cannot recover if the plaintiff is 50 percent or more at fault.
- Modified comparative negligence with a 51 percent bar. The plaintiff cannot recover if the plaintiff is 51 percent or more at fault.
- Pure contributory negligence. Any fault by the plaintiff bars recovery. A handful of states still follow this rule.
Fault is allocated by the jury based on what each party did or failed to do. A plaintiff who ignored a posted warning sign, was looking at a phone, or wore unsafe footwear may bear a share of fault. The split affects both the amount of recovery and the settlement value of the case.
Special rules for public property
Slip and fall cases against governmental entities operate under different rules. Most states have a tort claims act that limits when and how the government can be sued, sets short notice deadlines, often 30 to 180 days, and caps damages. Failing to file the required pre-suit notice within the statutory window can bar the entire claim regardless of merit.
Federal property is governed by the Federal Tort Claims Act, which requires a written administrative claim filed within two years and a six-month period for agency action before suit can be filed. Federal claims also have their own procedural quirks that differ from state court litigation.
Notice rules under tort claims acts are jurisdictional. Missing them is fatal in most states, regardless of how strong the underlying claim looks on the merits.
Common misreads we see plaintiffs make
Misread one: assuming the fall itself proves the case. It does not. The plaintiff has to identify the hazard, prove the owner knew or should have known about it, and prove that the owner's failure caused the injury. A fall without evidence of cause is not a case.
Misread two: posting on social media. Photos, status updates, and check-ins after the fall can undermine the case. Insurers and defense counsel monitor social media for evidence that the plaintiff's claimed limitations are inconsistent with daily activity. The right time for social media is much later.
Misread three: missing the pre-suit notice deadline on a public-property fall. Falls in front of city hall, in a public school, or on a county sidewalk trigger tort-claims-act notice rules. Those windows are short and unforgiving.
Practical next steps
Step one: document immediately. Take photos of the hazard, the surrounding area, and the footwear worn. Note the time and the names of any witnesses. Report the fall to the property manager and ask for a written incident report. Request copies.
Step two: seek medical care promptly. Medical records become the spine of the damages case. Gaps in treatment give the defense an argument that the injury was minor or unrelated. Follow through on referrals and physical therapy.
Step three: send a preservation letter. A written letter to the property owner and any building manager demanding preservation of surveillance video, incident reports, maintenance logs, and inspection records helps protect notice evidence. Send it as soon as possible after the fall.
