The insurance company had na independent audit completed and confirmed that this company was guilty. Further, the only document I signed was to permit the company to receive payments directly from the insurance company. The insurance company paid for reasonable charges as determined by the audit. The company has since billed us for the difference. The want to lien against our homestead even though my husband and I did not sign a contract and consequently the contract was not filed. What remedies do I have?
