Any filing officer may reject for filing or recording any nonconsensual common law lien.

If a nonconsensual common law lien has been accepted for filing, the filing officer shall accept for filing a sworn notice of invalid lien on a form provided by the filing officer signed and submitted by the person against whom such lien was filed or such person's attorney. The form shall be captioned "Notice of Invalid Lien" and shall state the name and address of the person on whose behalf such notice is filed, the name and address of the lien claimant and a clear reference to the document or documents the person believes constitute a nonconsensual common law lien. A copy of the notice of invalid lien shall be mailed by the filing officer to the lien claimant at the lien claimant's last known address within one business day. No filing officer, county or the state shall be liable for the acceptance for filing of a nonconsensual common law lien, nor for the acceptance for filing of a sworn notice of invalid lien pursuant to this subsection.
