Trespassing, Provocation & Owner Knowledge

Delaware's strict liability statute has exactly three exceptions, written directly into the statutory text — no more, no less.

The three exceptions, in the statute's own words

Under 16 Del. C. §3053F, liability doesn't apply if the injured person was, at the time: (1) committing or attempting to commit a trespass or other criminal offense on the owner's property, (2) committing or attempting to commit a criminal offense against any person, or (3) teasing, tormenting, or abusing the dog.

Provocation is read narrowly

Delaware courts don't apply the provocation exception loosely. Simply approaching a dog, or accidentally startling it, is unlikely to qualify as teasing, tormenting, or abusing — the conduct generally needs to be more deliberate or antagonizing than ordinary, careless behavior around an unfamiliar animal.

A warning sign isn't a standalone defense

Posting a "no trespassing" or "beware of dog" sign doesn't automatically defeat a strict liability claim on its own. A sign may support a broader trespass argument depending on the full circumstances, but it isn't, by itself, one of the statute's three exceptions.

The trespass exception is property-specific

The trespass exception requires the person to be trespassing or committing a criminal offense specifically on the dog owner's own property. Being unlawfully present somewhere else entirely — a different property, for instance — doesn't trigger this particular exception.

Comparative negligence still applies beneath the exceptions

Even short of one of the statute's three full exceptions, conduct contributing to the incident can factor into Delaware's modified comparative negligence rule — reducing recovery proportionally up to 50% fault, and barring it entirely once fault exceeds that.
