Proving a slip and fall lawsuit requires more than just proving that the property on which you slipped was in dangerous condition. Slip and fall lawsuits are about proving negligence and carelessness. What you and your attorney will need to prove regarding the dangerous condition includes:
Did the property owner create the dangerous condition? Did they know of this dangerous condition and fail to correct it? If they were not aware of the dangerous condition, had enough time passed that a reasonable property owner would have noticed and fixed it?
