New Hampshire lien waiver requirements

Rules that change the workflow

1. No printed routine form does not make New Hampshire generic. The official Chapter 447 index lists the operative lien, notice, attachment, priority, public-fund, and bond sections but no payment-stage waiver template. New Hampshire needs its own no-prescribed-form source record. SubLien may offer carefully labeled, customer/counsel-reviewed authored forms; it must never call one a New Hampshire statutory form.

2. The statute does not answer the broad advance-waiver question. Chapter 447 contains no general printed rule declaring every advance private lien waiver valid or void. Software must not infer either result from that silence. The only express waiver rule located in the chapter is the narrower construction-mortgage priority provision in RSA 447:12-a. Any broad pre-work or prepayment release should be escalated to New Hampshire counsel.

3. A downstream claimant's notice changes the amount protected. Under RSA 447:5, a person working through an agent, contractor, or subcontractor has the stated lien if written notice is given to the owner or person in charge. RSA 447:6 allows later notice, but then ties the lien to the amount due or later becoming due to the claimant's upstream contracting party. A waiver request does not provide that notice, cure a missing notice, or calculate the protected amount.

4. The 30-day account is part of draw control. RSA 447:8 calls for a written account as often as once every 30 days from a person using the downstream notice route and tells the owner to retain enough money for that claim. A GC's pay-run board should distinguish this account from a lien waiver. One is a statutory notice/account supporting retained funds; the other is a claimant's release document.

5. Payment and a promissory note are not interchangeable. RSA 447:9 continues the private lien for 120 days unless payment is previously made. RSA 447:14 says taking a note does not defeat the lien unless the note was taken in discharge of both the amount due and the lien. SubLien must not treat a QBO bill, pay application, promise to pay, or uncollected check as proof that the claimant received payment. A conditional document should wait for final collection of the identified funds.

6. New Hampshire perfects the private lien by attachment. RSA 447:10 allows the lien to be secured by an attachment while the lien continues. RSA 511-A:8, III permits the writ to be filed at the registry of deeds as a property-specific lis pendens, and the official Norcross order confirms that procedure. A routine payment waiver is neither the writ nor its discharge.

7. An attachment discharge is a separate recorded task. When a prejudgment attachment is dissolved or released, RSA 511-A:11 requires the plaintiff or plaintiff's attorney, on request, to provide a discharge that may be filed or recorded where the attachment was filed. RSA 511:8 separately addresses recording a discharge after a real-estate attachment is dissolved. SubLien's ordinary waiver should preserve that process and must not show “lien released” merely because a payment-stage PDF was signed.

8. Construction-mortgage priority has a payment-evidence gate. RSA 447:12-a gives the attachment priority over a construction mortgage, subject to the mortgagee's showing that loan proceeds paid subcontractor/supplier invoices or that the mortgagee received the described completion-and-payment affidavit. An agreement waiving that priority is enforceable only on a like showing. A generic lien release cannot substitute for a lender disbursement record, the statutory affidavit facts, or a deliberately scoped priority/subordination instrument.

9. The lender-notice lane is separate too. RSA 447:12-b requires the mortgagor or agent to post lender information within 10 business days after executing the construction mortgage. A potential lien claimant then has a 15-business-day written-notice step measured from the posting or its commencement of furnishing, whichever is later; failure alone does not invalidate the lien. The section also recognizes written two-party-check arrangements. These facts belong in project and draw controls, not silently inside a waiver.

10. Public work has both fund and payment-security tracks. RSA 447:15 attaches the Chapter 447 remedy to money due or becoming due under a public contract and uses a 90-day completion-and-acceptance filing period. RSA 447:16 generally requires 100% payment security when the state contract is at least $75,000 or a political-subdivision contract is at least $125,000, while allowing security below those amounts. A private-property waiver is not the correct document for either public right.

11. The public claim's office and clocks matter. RSA 447:17 sends the claim to different offices depending on the contracting party: the secretary of state, DOT, DAS, or the applicable superior-court clerk. It uses 90 days after completion and acceptance. RSA 447:18 then gives the claimant one year after filing to petition in superior court. A reminder ladder or unsigned waiver link does not suspend either deadline.

12. “Final waiver” can mean a contract closeout package, not a statutory form. New Hampshire DOT-hosted project documents show owners using final forms that combine a lien release, final-payment amount, lower-tier payment certification, seal, and notarial acknowledgment. Those are contract documents for identified projects—not forms Chapter 447 prescribes statewide. SubLien should collect the owner's required form when one exists and must not auto-label its simpler authored final waiver as satisfying that package.

13. Routine e-signing is supportable, but consent and attribution remain facts. RSA 294-E:5 makes electronic transacting depend on the parties' agreement. RSA 294-E:7 prevents denial solely because a record or signature is electronic, while RSA 294-E:9 makes attribution and effect depend on the person's act and surrounding context. SubLien's evidence chain helps document those facts; it does not decide authority or enforceability.

14. Notarization and government acceptance are separate decisions. The routine Chapter 447 payment-waiver provisions reviewed here prescribe no notarial block. If a contract form requires notarization, RSA 294-E:11 recognizes an electronic notarial act only when the authorized officer's signature and required information are associated with the record. A SubLien signature, PDF seal, or timestamp is not that act. RSA 294-E:18 also says the state does not have to accept electronic records; the recipient office's format and delivery rules must be checked.

Practical qualified-GC workflow

1. Classify the job as ordinary private property, construction-mortgage-funded private work, public work, or a project with an already-filed attachment. Record the contracting party and claimant tier.
2. Keep the RSA 447:5/:6 owner notice, RSA 447:8 account, RSA 447:12-b lender notice, and payment-stage waiver as separate checklist items. Do not mark one complete because another was signed.
3. For a private draw, match one claimant, payer, payment reference, amount, through date, retainage, later work, changes, and disputed items. Use a conditional document until the identified funds are finally collected.
4. Record actual payment evidence. Do not promote a QBO bill, Procore pay application, note, or GC attestation into independent proof of claimant receipt.
5. Request an unconditional instrument only after the payment facts support the exact recital the claimant will sign. Keep its scope limited to the identified private-property lien rights and payment.
6. If a construction lender wants priority waived or subordinated, use a separate counsel-reviewed workflow that captures the RSA 447:12-a disbursement or affidavit showing. Do not reuse the ordinary waiver.
7. For public work, capture the awarding body, completion-and-acceptance date, payment security, principal, surety, required claim office, 90-day filing, and one-year petition clock. Use a public-fund or bond document only when intentionally reviewed for that right.
8. If an RSA 447 lien attachment was filed, route its release to the plaintiff/plaintiff's attorney, court, and registry process under RSA 511-A. Preserve the recorded discharge rather than treating the signed draw waiver as proof of release.
9. At final closeout, reconcile the contract-required package, lower tiers, retainage, changes, claims, surety consent, seal, notary, and agency acceptance. Store those artifacts beside—but do not conflate them with—the routine waiver.
