44A-24.8. Enforcing lien.
A lien claimant may bring suit to enforce a lien which attaches pursuant to the provisions of this Part in any court of competent jurisdiction in the county where the commercial real estate is located. The lien claimant shall commence proceedings within 18 months after filing the lien, and failure to commence proceedings within the 18 months shall extinguish the lien. If a claim is based upon an option to purchase the commercial real estate, the lien claimant shall commence proceedings within one year of the option to purchase being exercised. A claim for the same lien extinguished pursuant to this section and G.S. 44A-24.10 may not be asserted in any subsequent proceeding. A lender shall not be made a party to any suit to enforce a lien under this Part unless the lender has willfully caused the nonpayment of the commission giving rise to the lien.
