Premises, Strict, and Multi-Party Liability

Homeowners liability claims turn on the common-law status of the person injured on the premises. An invitee — a business visitor or member of the public invited onto the land — is owed the highest duty: reasonable care to inspect for non-obvious dangers, correct them, or warn. A licensee, typically a social guest, enters with permission for their own purposes; the possessor need not inspect but must warn of known concealed dangers and refrain from willful or wanton conduct. A trespasser is generally owed only the duty not to be willfully injured, with heightened duties for highly dangerous activities near known trespassers. The attractive nuisance doctrine overrides trespasser rules for children: an artificial condition likely to lure children who cannot appreciate the risk — the swimming pool is the exam's standard example — imposes a duty of reasonable care on the landowner. Some liability attaches without any proof of fault. Strict liability applies to abnormally dangerous activities — the actor is liable even having exercised the utmost care, with factors including high risk, gravity of harm, inability to eliminate risk through care, uncommonness, and inappropriateness to the location. Strict products liability makes commercial sellers of defective, unreasonably dangerous products liable without negligence; a defect can even be inferred circumstantially when the incident is of a kind that ordinarily results from a defect and other causes existing at sale are ruled out — crucial when the product burned up in the fire it caused. Animal liability splits similarly: owners face strict liability for animals with known vicious propensities (the dog-bite context), negligence standards otherwise, with many statutes imposing strict liability directly. Liability also spreads across people. Vicarious liability (respondeat superior) makes a principal answer for an agent's torts in the scope of the relationship, while negligent entrustment is the owner's own direct negligence — supplying a car to someone the owner knows is likely to create unreasonable risk because of youth, inexperience, or intoxication. Negligent supervision of children, negligent undertaking of services for another's protection, and failure to warn users of a known chattel danger complete the family. When multiple tortfeasors cause one indivisible injury, joint and several liability lets the plaintiff collect the entire judgment from any one defendant, who then seeks contribution from the others for their equitable shares; pure several liability jurisdictions instead cap each defendant at their own comparative-fault percentage, leaving the plaintiff bearing insolvency risk. Social-host and dram shop rules extend alcohol-service liability by statute in many states.
