The condition of the property and activities of the owners, visitors and licensees are given consideration in some states. Reasonable care must be given to any visitor or licensees, but not to trespassers. Owners must continually inspect property and repair or place warnings on any dangerous conditions. The injured party must show neglect to the standard of reasonable upkeep by the owner to prove a premises liability case and prove the owner had knowledge of the danger. The injured party must also show that they took reasonable care for their own safety. It is very difficult to prove owners knew of dangers and that injured parties took reasonable care to avoid the danger.
