I have had a lien filed our our home build from the lumber yard. We have cancelled checks from our General to pay for these materials that were not applied paid to the lumber yard. The contractor used another LLC to acquire the supplies. We do not have a contract with that LLC. The LLC that opened the account with the lumber yard never made a payment to the account. The lumber yard continued to deliver supplies for over 4 months with no payments. Does the lumber yard have a responsibly to make sure the LLC's they are extending credit to are creditable or can they just use the fact that they can file a lien as security for payment. Thanks for your help, Tim
