What Is a Notice of Intent to Lien?
A notice of intent to lien — commonly abbreviated NOI, and sometimes called a pre-lien notice, intent-to-file notice, or notice of nonpayment — is a formal written warning sent by an unpaid construction participant to the property owner and the general contractor stating that, unless the outstanding balance is paid within a specified number of days, a mechanic's lien will be filed against the project's real property. The NOI is the penultimate step in the construction collection process. It comes after invoicing, after internal follow-up, after dunning letters, and after any preliminary notice required at the start of the project — but before the actual filing of the lien itself.
The NOI serves two distinct functions. First, in a number of states it is a mandatory statutory step that must be completed in the exact manner required by law before a lien can be validly filed. In those states, skipping the NOI or sending it in the wrong manner is fatal to the underlying lien, no matter how legitimate the unpaid claim may be. Second, and just as importantly, the NOI is the most effective collection tool in the construction industry — even in states that do not require one. When the owner receives an NOI, they are put on direct notice that their title is about to be encumbered, and the pressure to produce payment from somewhere in the contractor chain becomes intense. Industry data show that 70 to 90 percent of NOIs result in payment before a lien is filed.
The NOI is a creature of state statute. Every state's mechanic's lien law is different, and the NOI requirements — when it is required, what it must say, how it must be delivered, how many days must pass before the lien can be filed — vary enormously. Some states (Arkansas, Colorado, Nevada, Pennsylvania, Wisconsin, Wyoming and others) require an NOI before filing. Other states (California, Texas, and most of the South) do not require an NOI but have other prerequisite notices. A handful of states have no pre-lien notice requirement at all.
Even in states that do not require an NOI, sending one voluntarily is almost always a sound business decision. It costs a few dollars in certified mail, preserves the business relationship by giving the owner a chance to resolve the dispute before the lien is filed, and produces payment the overwhelming majority of the time. Our templates handle the state-by-state variations automatically so you do not have to research the statute yourself.

When Is a Notice of Intent Required?
State requirements fall into three categories: (1) states that mandate an NOI before any lien can be filed; (2) states that do not require an NOI but have other pre-lien notice requirements; and (3) states with no pre-lien notice requirement at all. The list below covers the principal mandatory-NOI states; always verify the current statute before sending.
Notice of Intent to Lien
Warning letter sent to the owner and GC before filing a mechanic's lien — often the trigger that produces payment.
Preliminary Notice (20-Day Notice)
Mandatory notice sent at the start of work in many states to preserve lien rights — not the same as a notice of intent.
Notice to Owner (Florida)
Florida's statutory preliminary notice under Fla. Stat. § 713.06, due within 45 days of first furnishing.
Pre-Lien Notice
Generic industry term for any statutory warning that must precede a lien filing.
Notice of Furnishing
The term used in Michigan, Ohio, and several other states for the statutory preliminary notice.
Final Demand Letter
A non-statutory collection letter that precedes (and is often combined with) a formal notice of intent to lien.

How to Send a Notice of Intent
Verify the Recipient Information
Pull the current record owner from the county recorder's website or a title search. Do not rely on the name on the contract — ownership may have changed since the project started. Also identify the general contractor, any construction lender, and any disbursement escrow agent identified in public records.
Confirm the Amount Owed
Reconcile your books to confirm the exact unpaid principal, any contractually permitted interest, and any lawful collection costs. Sending an NOI for the wrong amount is a defect that can undermine the notice and the later lien.
Verify First and Last Furnishing Dates
The NOI typically requires both dates. These dates drive the lien filing deadline, so they must be supported by daily reports, delivery tickets, time sheets, or pay applications. Do not estimate — document.
Draft the Notice Using the Statutory Form
Many states have a specific form; even those without one have specific content requirements. Using a state-aware template (like ours) eliminates the guesswork.
Send via Certified Mail, Return Receipt Requested
Almost every NOI statute requires certified mail. Some additionally allow or require personal service or statutory overnight delivery. Keep the green card, the certified mail receipt, and the tracking printout as proof of service.
Copy All Relevant Parties
Send to the owner, the GC, any lender, and (optional but recommended) the title company and the project's escrow or disbursement agent. The more stakeholders who see the notice, the faster the payment pressure builds.
Calendar the Waiting Period and the Lien Deadline
The NOI waiting period does not toll the hard lien filing deadline. Calendar both dates. If the NOI waiting period would cut it close, send the NOI earlier to preserve your options.
Follow Up and File if Necessary
If payment is not received by the end of the waiting period, file the lien immediately. Do not let the lien filing deadline slip while waiting for a late payment that is not coming.
What Happens After You Send the Notice
Once the NOI is delivered, one of four things typically happens. First and most commonly, the owner or general contractor produces payment — often within days, as pressure flows down the payment chain. Second, the parties open negotiations and work out a revised payment schedule or settlement, frequently memorialized in a written settlement and release. Third, the owner or GC disputes the claim and demands documentation, in which case the claimant must be prepared to substantiate every dollar with contracts, pay applications, delivery tickets, and time sheets. Fourth, the waiting period expires without resolution, and the claimant proceeds to file the formal mechanic's lien.
If payment is made before the deadline, the claimant should immediately issue the appropriate lien waiver — conditional on clearance of the payment, upgraded to unconditional once the funds have cleared — and confirm in writing that no lien will be filed. Failing to close out the NOI properly can leave the owner, lender, and title company uncertain about the status of the claim and creates risk for all parties.
