A fall can become an evidence case quickly.

The fall takes a second. What follows takes months. The ankle that "felt twisted" turns out to be fractured. The headache that started in the car going home turns out to be a concussion. The shoulder pain you ignored for a week is a labral tear that needs surgery. The store's adjuster calls within forty-eight hours with a friendly voice and a quick-resolution offer. The incident report you signed at the scene says "minor fall, no injuries reported." The surveillance video of the produce-aisle spill that caused the fall gets overwritten on a 14-day cycle. And the witness who saw it happen has a new phone number by the time the lawyer needs to call.

Premises-liability cases are built from evidence, not from the label attached to the accident. The early work is to identify who controlled the property, what duty applied, whether notice can be proven, and what evidence needs to be preserved before it disappears.

Key terms

Premises Liability and Insurance Terms

Definitions for concepts that affect fault, notice, evidence preservation, public-entity claims, and insurance handling after a fall.

Premises liability

The area of injury law involving unsafe property conditions, including falls, falling merchandise, negligent security, and animal attacks.

Business invitee

A customer, tenant, contractor, or other person invited for business purposes. New Jersey law generally gives invitees the highest premises duty.

Licensee

A person allowed on property for non-business reasons, such as a social guest. The owner usually must warn of known, non-obvious dangers.

Actual notice

Proof that the owner or operator actually knew about the hazard before the injury.

Constructive notice

Proof that a hazard existed long enough that a reasonable owner should have discovered and fixed it.

Mode-of-operation rule

A New Jersey doctrine for certain self-service businesses where the plaintiff may not need to prove notice of the exact spill or hazard.

Open and obvious

A defense argument that the hazard was visible enough that the injured person should have avoided it.

Spoliation

The loss or destruction of evidence, such as surveillance video, incident reports, maintenance logs, or the physical hazard.

Tort Claims Act notice

A 90-day notice requirement for many claims involving public property or public employees in New Jersey.

Dangerous condition

For public-entity claims, a property condition that creates a substantial risk of injury when used with due care.

Palpably unreasonable

The higher public-entity liability standard under the New Jersey Tort Claims Act.

Incident report

A business or property-owner record created after a fall. It can help prove timing, notice, witnesses, and what staff knew.

What is a premises-liability case?

Premises-liability law holds owners and occupiers of property responsible for keeping their premises in reasonably safe condition for people lawfully on them. The duty's scope depends on the visitor's status -- business invitees, customers, residents, and contractors are owed the highest duty; licensees (social guests) a lower duty; trespassers the most limited. When hazardous conditions -- wet floors, ice and snow, broken stairs, uneven pavement, inadequate lighting, falling merchandise -- cause injury, the case turns on what the owner knew, when they knew it, and what a reasonably prudent owner would have done.

The mode-of-operation rule -- and why it matters in supermarkets.

For decades, the rule in New Jersey premises cases was that the plaintiff had to prove the owner had notice of the specific hazard that caused the fall. Notice could be actual (the owner knew about the spill) or constructive (the spill had been there long enough that a reasonable owner would have discovered it). Without notice, the case failed.

Wollerman v. Grand Union Storessource changed that analysis for some self-service businesses. Where the business operation itself foreseeably produces hazards, such as produce sections, prepared-food counters, or customers handling merchandise, the plaintiff may not need to prove notice of the specific hazard. The plaintiff still has to connect the hazard to the self-service operation and prove causation and damages.

Outside the self-service context -- a bank lobby, a doctor's waiting room, an office building -- the plaintiff still must establish notice. The distinction is fact-specific, and the carrier often tries to characterize the venue as not self-service. The plaintiff's first move is to document the actual operations on the day of the fall.

Sidewalk falls -- commercial vs. residential.

New Jersey distinguishes sharply between sidewalks in front of commercial and residential properties. Under Stewart v. 104 Wallace Street, Inc.source, a commercial property owner has a duty to maintain the abutting public sidewalk in reasonably safe condition and is liable for failures (including failure to clear snow and ice). Under Yanhko v. Fanesource, residential homeowners generally do not have that duty -- unless they created the hazard (a hose left running that froze; a defective repair they performed; tree roots from a tree they planted that buckled the slabs).

The classification is not always obvious. Multi-family, mixed-use, and home-business properties require fact-specific analysis of ownership, use, control, and who created or maintained the condition. Pre-suit investigation matters: tax records, deed records, business filings, leases, maintenance contracts, and prior complaints may determine whether the case is viable.

Dog bites -- strict liability under N.J.S.A. 4:19-16.

Most dog-bite cases in New Jersey proceed under N.J.S.A. 4:19-16source, which imposes strict liability on the owner of a dog that bites a person in a public place, or lawfully on private property. The plaintiff does not need to prove negligence; the plaintiff does not need to prove the dog had bitten before. The owner is liable as long as the plaintiff was lawfully present (a business invitee, a licensee on permitted premises, or someone in a public place). Defenses are narrow -- provocation by the plaintiff is the most common, but the bar is high.

Insurance coverage depends on the policy and exclusions. Where the owner is uninsured or coverage is disputed, counsel may investigate whether any other party had legally relevant knowledge or control, such as a landlord in a rental-property case with a known dangerous-propensity history.

Premises claims against public entities -- the Tort Claims Act trap.

Slip-and-fall and trip-and-fall claims against public entities, such as municipal property, state-owned facilities, public-school property, county parks, or public hospitals, are governed by the New Jersey Tort Claims Act, N.J.S.A. 59:1-1source et seq. Two consequences:

• A 90-day Notice of Tort Claim generally must be filed under N.J.S.A. 59:8-8source. Missing the notice can bar the public-entity claim even within the two-year statute of limitations.
• A higher liability standard. Public entities are immune from suit except for "dangerous conditions" that were "palpably unreasonable," of which the entity had actual or constructive notice and where money damages would not "unfairly impose financial responsibility." The standard is materially higher than the private-property standard.

Identifying public-entity defendants early is essential. A fall in a parking lot can implicate the property's private owner and the municipal entity that owns the sidewalk where the parking lot ends. A fall in a county park triggers Tort Claims Act analysis from day one.

Comparative fault -- and why "open and obvious" is the carrier's first argument.

New Jersey follows modified comparative negligence under N.J.S.A. 2A:15-5.1source. A plaintiff who is 50% or less at fault can recover, with damages reduced by the plaintiff's percentage of fault; a plaintiff who is 51% or more at fault recovers nothing. In premises cases, the carrier often argues the hazard was "open and obvious" -- that a reasonably prudent person would have seen and avoided it.

The plaintiff's response is to focus on the specific circumstances: lighting at the time of the fall, the plaintiff's vantage angle, distractions in the store environment, the lack of warning signs or cones, the position of the hazard relative to the path of egress. Surveillance video that captures the entire approach to the fall is often dispositive on this point. So is the testimony of witnesses who saw the same hazard without falling -- because the carrier will surface them to argue the hazard was avoidable.

How fees work in slip-and-fall cases.

Slip-and-fall work is contingency-fee work under New Jersey Court Rule R. 1:21-7source. There is no upfront attorney fee; the attorney fee is paid from a recovery if one is obtained, under the written contingency-fee agreement. The contingency-fee cap under R. 1:21-7 is tiered: 33⅓% on the first $750,000 recovered, 30% on the next $750,000, 25% on the next $750,000, 20% on the next $1,000,000, and reasonable fees on the balance.

What to do in the next 48 hours.

If your fall just happened, the next two days matter more than most people realize.

1. Get medical care today, even if you "feel fine."

Adrenaline masks symptoms for 24 to 72 hours. Concussions, soft-tissue injuries, and internal bleeding can present hours or days after impact. The ER or urgent-care visit creates a contemporaneous medical record dated to the fall -- without it, the carrier will argue your injuries came from somewhere else.

2. Photograph the hazard -- before it gets fixed.

Most spills are mopped, most ice melts, most broken stairs get repaired within 24 to 48 hours of an incident. Photographs taken at the scene, with the hazard visible and with measurements where possible (a phone next to a crack provides scale), are some of the most-valuable evidence available. Date-stamped on a phone, locked to a cloud account.

3. Get the incident report -- and your copy of it.

Stores fill out incident reports when falls happen. Ask for a copy before you leave. If the store says you have to "request it later," document the request and the response in writing. Incident reports get edited, lost, and revised after the fact.

4. Get names and contact information of any witnesses.

Anyone who saw the fall, anyone who saw the hazard before the fall, anyone who heard staff discuss the hazard. Phone numbers and addresses, not just first names. People move; witnesses become unreachable.

5. Preserve the shoes you were wearing.

In the same condition. Do not clean them. Do not throw them away. The tread, the sole condition, the type of footwear all become evidence in cases where the carrier argues plaintiff fault.

6. Write down what happened -- in your own words, within 24 hours.

Date the document. Mark it "Confidential -- Prepared for Counsel." Include the time of day, the lighting conditions, who you talked to at the store, who else was present, and exactly what you observed about the hazard before and after the fall. Memory degrades fast; contemporaneous notes are evidence under N.J.R.E. 803(c)(5)source.

And the one thing not to do -- don't talk to the property's insurance company.

A recorded statement can become part of the defense record. Politely decline until you have had a chance to speak with counsel.
