In most situations, the only duty of care a property owner owes to a person who is on the land illegally is to refrain from actively trying to hurt that person or other trespassers. Accordingly, it can be difficult for a trespasser to file suit for injuries they suffered from a slip and fall.
However, under the attractive nuisance doctrine, landowners can be liable for slips and falls suffered by trespassing children—specifically, if the landowner failed to take reasonable measures to keep children away from an “attractive nuisance” such as a swimming pool.
