> Serve a written Notice of Lien on the owner before performing labor, or in writing before furnishing materials. Required for any claimant not in direct contract with the owner. The Notice of Lien preserves lien rights against the owner; without it, the lien is limited to amounts the owner owes the prime contractor at the time notice is given.
