Fla. Stat. § 680.1095

This act does not apply to any lease contract entered into before the effective date of this act unless the parties thereto specifically agree in writing that the lease contract as expanded, amended, modified, renewed, or supplemented shall be governed by applicable law as supplemented or amended by this act. Absent such specific agreement, transactions validly entered into before that date and the rights, duties, and interests flowing from them remain valid thereafter and may be terminated, completed, consummated, or enforced as though this act had not taken effect.
