My Florida homebuilder had not completed our house after more than a year after start of construction, so we fired him. There was also a lien on the property for roofing materials, an NTO from another sub, and he was demanding payment for unfounded/unsubstantiated invoices. As the direct contractor, does he have to serve me with a Notice to Owner before filing a lien on my property? If not, does he have a time limit for filing?
