Georgia contractor filed a mechanics lien for a remainder portion of a project. The amount is in dispute due to (1) failure to perform; (2) improper performance; (3) negligence; and (4) failure of duty of care. The damage caused by the actions of the contract is likely more than the remainder amount per the signed contract. It is also found during dispute that contractor is not licensed in the State of Georgia, which makes them ineligible to file a mechanics lien or otherwise seek to enforce contract in the first place. The remainder amount (which is also disputed) is between 4-5K. I would like to know what is the best step to take.
