We are a general contractors that perform commercial and residential renovations. However, our client has refused to pay the final balance that is now past due for the services that we already completed for her home. We then filed a mechanics lien on the property. We are now ready to file a notice to foreclosure lien document since we still haven't received payment. However, we were just informed that a notice to lien document was required first in NC. Should we still proceed with filing the notice to forclosure lien document?
