Recording and enforcing a New Hampshire lien
Recording the lien
Record with the circuit court clerk for the county. Electronic recording is available in participating counties. No notary is required on the lien itself. No sworn statement or verification is required.
After recording
New Hampshire does not require a separate notice after the lien is recorded, though most claimants send one anyway to prompt payment.
Wrongful lien exposure
New Hampshire 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 New Hampshire
Subcontractor/supplier notice: for those contracting with a GC/sub, written notice to owner/person in charge is required to claim a lien before performing/furnishing (RSA 447:5); notice may also be given after, but lien is limited to amounts then due or thereafter due to the contractor/agent/sub (RSA 447:6). After giving notice, claimant must provide a written accounting as often as once in 30 days (RSA 447:8). Lien duration: lien continues for 120 days after services/materials are furnished (RSA 447:9). Perfection: lien is secured by court attachment of the property at any time while the lien continues (RSA 447:10); attachment is then recorded at the registry of deeds. Pre-lien notice has no strict statutory day-count deadline; notice triggers owner's duty to withhold and 30-day accountings may apply.
Statutory sources: RSA 447:5, 447:6, 447:8, 447:9, 447:10. Read the New Hampshire lien statute.
