New Hampshire: Mechanic's Lien Waiver Form and Advance-Waiver Rules
The short answer
New Hampshire does not regulate lien waivers. RSA chapter 447 has no rule making an advance or 'no-lien' waiver void and prescribes no statutory waiver form, so a waiver — including one signed before work or before payment — is treated as an ordinary contract and is generally enforceable on its terms. The only waiver-related statute, RSA 447:14, says taking a promissory note does not defeat a lien unless the note was taken in discharge of the amount due and of the lien.

| Governing law and project scope | New Hampshire RSA ch. 447 (Liens for Labor and Materials). A lien for anyone who performs labor, provides professional design services, or furnishes materials of $15 or more to erect or repair a house or other building or appurtenances, or to build a dam, canal, well, or bridge, by virtue of a contract with the owner (RSA 447:2). Private work; public projects use a payment bond (RSA 447:15–16). No separate waiver statute or waiver form. |
|---|---|
| Advance or prospective waiver | Not prohibited. Chapter 447 has no anti-waiver or 'no-lien clause void' provision, and New Hampshire imposes no statutory bar on waiving lien rights before work or before payment. RSA 447:14 confirms that even taking a note does not defeat a lien 'unless it was taken in discharge of the amount due and of the lien' — a lien is surrendered by agreement, so a clear contractual waiver, including an advance one, is generally effective. |
| Statutory form requirement | None. No section of ch. 447 prescribes a waiver form, conditional/unconditional or progress/final labels, warning language, or required fields. A waiver's form and content are set entirely by contract. |
| Waiver types and payment stage | No statutory conditional/unconditional or progress/final distinctions and no statutory partial, through-date, or amount-limited release. Any such structure exists only if the parties write it into the document. |
| Payment and effectiveness | No statutory rule on when a waiver takes effect, no ban on demanding an unconditional waiver before payment, and no cleared-check or evidence-of-payment condition. A waiver is effective on its own terms; RSA 447:14 shows an instrument surrenders the lien only when clearly given 'in discharge,' so any payment or fund-clearance condition must be drafted in. |
| Required contents, exceptions, and through date | None prescribed. Chapter 447 supplies no required claimant, owner, amount, or through-date fields and no default carve-out for retainage, extras, change orders, or later work. A waiver reserves only what its own text reserves. |
| Rights released and reserved | A waiver reaches whatever RSA 447:2 lien rights its text releases. Chapter 447 creates no statutory stop-payment-notice right; the public-project remedy is a payment bond under RSA 447:15–16, outside a private-work lien waiver. |
| Signature, authority, notary, and format | Not specified. No statute requires a claimant's or agent's signature, an authority statement, notarization, a warning, an electronic-form rule, or attachments for a lien waiver. Format is a matter of contract. |
| Noncompliance, remedies, and transition traps | No statutory void, penalty, or ineffectiveness rule for a premature or nonconforming waiver, because New Hampshire sets no statutory waiver standard. A waiver stands or falls on its own terms and general contract law; because nothing voids an advance waiver, a New Hampshire no-lien clause is generally enforceable. No pending bill would change this. |

What New Hampshire's silence means
New Hampshire's mechanic's lien law is RSA chapter 447. It creates the lien for
labor, professional design services, or materials of $15 or more furnished to a
building by contract with the owner (RSA 447:2), and it lays out how a
subcontractor perfects the lien through notice to the owner. What it does not do
is regulate lien waivers. There is no section making a "no-lien" clause void,
no rule barring a waiver before payment, and no statutory waiver form of any kind.
Because the statute supplies nothing, a New Hampshire lien waiver is treated as
an ordinary contract. The parties decide whether it is conditional or
unconditional, what it covers, and how it is signed, and a clearly worded waiver
is generally enforced as written. New Hampshire is one of the relatively few
states that does not bar a party from waiving lien rights before the work even
begins — so an advance "no-lien" clause in a subcontract is generally effective
here, unlike in states that void such clauses by statute.
The one waiver-adjacent provision, RSA 447:14, points the same way. It says "no
lien shall be defeated by taking a note, unless it was taken in discharge of the
amount due and of the lien." In other words, a lien is given up only when an
instrument is clearly meant to discharge it. That confirms both that a lien can
be surrendered by agreement and that surrender turns on the document's clear
intent — which is exactly why the wording of any waiver matters so much here.
What trips people up
The freedom cuts hard against the party being asked to sign. In many states a
contractor can sign an advance waiver and later rely on a statute that voids it.
In New Hampshire there is no such backstop: a promise not to lien, signed before
work or before payment, is generally enforceable. A subcontractor handed a
subcontract with a "no-lien" clause should assume it will be given effect and
negotiate it, not count on a statute erasing it.
The absence of a statutory form means a waiver means exactly what it says.
Because there is no default rule tying effectiveness to a check clearing, an
unconditional waiver signed before funds arrive can release the lien even if the
payment later fails. If a signer wants protection, the waiver has to be made
conditional on actual receipt and clearance of the payment; RSA 447:14's
"in discharge" logic will hold the document to its own terms.
Common questions
Can I waive New Hampshire lien rights before the work starts?
Yes. New Hampshire has no statute barring an advance or pre-payment waiver, so a
clearly worded "no-lien" clause signed before work is generally enforceable — one
of the more permissive rules in the country.
Is there a required New Hampshire lien-waiver form?
No. RSA chapter 447 prescribes no conditional, unconditional, progress, or final
waiver form, warning, or field list. The document's wording is set by contract.
Does giving my customer a promissory note waive my lien?
Not by itself. Under RSA 447:14, taking a note does not defeat the lien unless the
note was taken in discharge of both the amount due and the lien.
