A Notice to Owner should either be (1) mailed by certified or registered mail to the owner or reputed owner, or (2) delivered or personally served upon the owner or reputed owner, with the lien claimant obtaining evidence of delivery (such as a receipt, affidavit of service, or acknowledgement signed by the owner or reputed owner).
Notice to Customer. The contractor must keep a copy of the Notice to Customer signed by the customer and retain it for at least three years. The
