(a) Except as provided in subdivisions (b) and (c), erroneous information contained in a claim of lien relating to the claimant’s demand, credits and offsets deducted, the work provided, or the description of the site, does not invalidate the claim of lien.

(b) Erroneous information contained in a claim of lien relating to the claimant’s demand, credits and offsets deducted, or the work provided, invalidates the claim of lien if the court determines either of the following:

(1) The claim of lien was made with intent to defraud.

(2) An innocent third party, without notice, actual or constructive, became the bona fide owner of the property after recordation of the claim of lien, and the claim of lien was so deficient that it did not put the party on further inquiry in any manner.

(c) Any person who shall willfully include in a claim of lien labor, services, equipment, or materials not furnished for the property described in the claim, shall thereby forfeit the person’s lien.
