768.72  Pleading in civil actions; claim for punitive damages.--In any civil action, no claim for punitive damages shall be permitted unless there is a reasonable showing by evidence in the record or proffered by the claimant which would provide a reasonable basis for recovery of such damages. The claimant may move to amend her or his complaint to assert a claim for punitive damages as allowed by the rules of civil procedure. The rules of civil procedure shall be liberally construed so as to allow the claimant discovery of evidence which appears reasonably calculated to lead to admissible evidence on the issue of punitive damages. No discovery of financial worth shall proceed until after the pleading concerning punitive damages is permitted.
