Your question leads me to believe that you are dealing with a consumer and not a costumer. Assuming that you conducted work which requires a contractors license as an unlicensed contractor, you may have committed a criminal act. You are prohibited from filing a mechanics lien for the unpaid balance but may be able to recover the remaining balance under contractual or equitable principles such as unjust enrichment.
