I know Iowa requires a preliminary notice of lien rights be provided to the customer before work begins or soon after. That being said, we do not have an "official form" for this; however, the fine print on our contract has a line that says the following: "Pre-Lien Notice: company hereby provides notification that any person or company supplying labor or material for this improvement to your property may file a lien against your property if that person or company is not paid for their contributions. Upon default in payment, a lien will be placed on the property and charges will be added from the date of substantial completion at the maximum rate allowed by law." Is this sufficient, or is there an actual official form that's needed in Iowa? Thank you in advance for any assistance you can give. Sincerely, Joe James
