Iowa does not require a notice of intent before recording a lien, but sending one is often what gets the invoice paid.
Recording and enforcing a Iowa lien
Recording the lien
Record with the county recorder where the property sits. Electronic recording is available in participating counties. No notary is required on the lien itself. The lien claim must be verified by the claimant.
After recording
A copy of the recorded lien must be served on the property owner promptly after recording. To keep the lien alive it must be enforced by lawsuit within 820 days after last furnishing labor or materials.
Wrongful lien exposure
Iowa has no dedicated wrongful-lien penalty statute, but an inflated or baseless lien can still be challenged and removed at the claimant's expense.
Practitioner notes for Iowa
Perfection: mechanic’s lien is perfected by posting a verified statement of account to the Mechanics’ Notice and Lien Registry (MNLR) (Iowa Code §572.8). Timing: lien statement may be posted within 2 years and 90 days after last furnishing (Iowa Code §572.9), but if posted after 90 days, additional service is required and the lien’s enforceable extent can be limited (Iowa Code §§572.10–.11). Residential construction: GC must give owner notice (Iowa Code §572.13) and must post a Notice of Commencement to MNLR within 10 days after commencement or loses lien rights (Iowa Code §572.13A). Residential subcontractor: must post MNLR preliminary notice; it must be posted before the balance due is paid to the GC/owner-builder or the subcontractor has no lien remedy (Iowa Code §572.13B). Commercial: a person furnishing labor/materials to a subcontractor must give a one-time written notice to the GC/owner-builder within 30 days of first furnishing (Iowa Code §572.33). Enforcement: action to enforce must be brought within 2 years from expiration of 90 days after last furnishing (Iowa Code §572.27); owner demand can accelerate to 30 days (Iowa Code §572.28). Prelim (commercial/residential subs/suppliers): post MNLR preliminary notice within 30 days of first furnishing for full protection.
