Florida Statute Section 713.31 provides that where a lien claimant has willfully exaggerated the amount of the lien, or has compiled the lien in a grossly negligent manner, such action is a complete defense to enforcement of the lien. In addition, and of critical importance to lienors, an injured party such as the owner may assert an affirmative claim of its own against the lienor for damages, costs and attorneys' fees resulting from the fraudulent lien.
