Contracted to install new roof by insurance adjuster/mitigator. A down payment of $6,000 was made. Balance due for work completed has never been paid. House has now been sold. Former homeowner not helping to secure funds from adjuster/mitigator. My husband wants to put a lien on the home (now with new owner who has no idea about any of this) and let them battle it out in court. Is this possible? An insurance investigator told me you couldn't lien on a house if the contractor had received partial payment and we would have to take to small claims court. Thank you
