Slip and fall cases are difficult to win, and property owners will argue that even though you were injured on their property, they should not be held responsible. If the hazardous condition was temporary (like a water spill), owners will probably argue that the spill occurred so soon before the incident that they could not have prevented it. They can also argue that a dangerous condition was so open and obvious that you should have seen it and are thus at fault for your own injury, or possibly that the owners were not even the ones that caused the dangerous condition.
You should also expect the land owner (or the owner's attorney) to argue that you fell because you were inattentive, careless, or even intoxicated at the time. If the land owner (or the owner's attorney) can prove that you were also at fault for your fall, that may reduce or eliminate your ability to recover for your injuries depending on the laws of your state. If you were injured due to a hazardous condition on someone else's property, you should seek the advice of an experienced personal injury lawyer right away.
