Effective July 1, 2010, the law regarding slip and fall cases involving a transitory foreign substance can be found at Section 768.0755, Florida Statutes. If a person slips and falls on a transitory foreign substance in a business establishment, the injured person must prove that the business establishment had actual or constructive knowledge of the dangerous condition and should have taken action to remedy it. A transitory foreign substance would be something like a spilled liquid, trash on the ground, etc. Constructive knowledge may be proven by circumstantial evidence showing either (1) the dangerous condition existed for such a length of time that, in the exercise of ordinary care, the business establishment should have known of the condition; or (2) that the condition occurred with regularity and was therefore foreseeable.
