A notice of intent to lien is a written warning sent to a property owner, and often to the general contractor, stating that a mechanic’s lien will be filed against the property unless an overdue payment is made within a set window. The notice itself does not create a lien and does not appear on the property’s title. It is a last-chance demand that sits between unpaid invoices and a public record filing, and it often resolves the dispute before anything is recorded at the courthouse.
One quick boundary before going further. A notice of intent to lien is not the same document as a preliminary notice. A preliminary notice goes out near the start of a project to preserve the right to lien later. The notice of intent comes at the end of the dispute, after payment is overdue, and announces that a lien filing is imminent. Mixing them up is a common and expensive mistake.
Is the Notice Legally Required
Whether you must send one before filing a mechanic’s lien depends entirely on the state where the property sits. There is no federal mechanic’s lien law. Each state sets its own rules on who must send the notice, when it must arrive, and what it must say.
In some states, the notice is a hard prerequisite for subcontractors and suppliers. Skip it, and the lien you later record is invalid on its face. In other states, no notice of intent is required at all, and a claimant can go directly from nonpayment to filing. Courts in states with mandatory notice requirements routinely throw out liens where the notice was never sent or was sent late. The lien does not become weaker. It becomes void. Check the rules of the state where the property is located, not the state where your business is based.
Who Sends the Notice
In states that require it, the obligation almost always falls on subcontractors and material suppliers. A general contractor has a direct contract with the owner, so the owner already knows who they are and what is owed. Subcontractors and suppliers are often invisible to the owner, and the notice requirement makes sure the owner learns about an unpaid party before a lien lands on the property.
General contractors are typically exempt and can proceed directly to filing. Many send a notice anyway as a practical matter. Putting the dispute in writing often prompts payment without the cost of filing and enforcing a lien.
What the Notice Must Contain
A valid notice needs enough information that the recipient can identify who is owed, how much, for what work, and against which property. Most state requirements call for:
- The full legal name and address of the claimant.
- The full name and address of the property owner, and often the general contractor as well.
- The specific dollar amount claimed for unpaid labor or materials.
- A description of the labor performed or materials supplied.
- The legal description of the property from official land records, not just the street address.
- The date by which payment must be received to avoid a lien filing.
Accuracy matters more than people expect. An error in the property description, the amount owed, or the spelling of the owner’s name can give the other side grounds to challenge the notice and any lien that follows. Some courts have invalidated liens over relatively minor clerical mistakes in the notice. When a lien worth tens or hundreds of thousands of dollars depends on a one-page document, the details are worth getting right.
How to Deliver It
Delivery is where otherwise valid notices fail. The point of the notice is to prove the owner was warned before a lien was recorded. If you cannot prove delivery, it is as if you never sent it.
Certified mail with return receipt requested is the safest and most widely accepted method. The signed receipt card creates a paper trail showing exactly who received the notice and when. Registered mail and personal delivery by a process server are also generally accepted, since both produce documented proof. Some states allow hand delivery with a signed acknowledgment.
Standard first-class mail is risky because it generates no proof of receipt. Email is generally not considered valid service, even in states that have modernized other areas of legal notice. Unless the state’s lien statute specifically authorizes electronic delivery, stick with certified mail or personal service. Keep every piece of delivery documentation in a file: the certified mail receipt, the return receipt card, tracking confirmations, and copies of the notice itself. If the dispute escalates, this paperwork is the evidence that procedure was followed.
Deadlines and the Timing Trap
Two separate timing issues matter.
The first is the deadline for sending the notice. This is typically measured from the last date the claimant provided labor or delivered materials to the project, not from the date payment was due. A subcontractor who finished work in March but was not supposed to be paid until June still counts the sending deadline from March. Waiting until an invoice is overdue may already be too late.
The second is the waiting period between sending the notice and being allowed to file the lien. Most states that require the notice set this gap somewhere between 10 and 30 days. During that window, the owner or general contractor can pay and end the dispute. If the window closes without payment, the claimant can proceed to file.
Here is the trap: sending the notice does not extend or reset the deadline for filing the lien itself. If the lien filing deadline is four months from the last day of work, the notice has to go out early enough that the waiting period expires before that four-month window closes. Send the notice on the last possible day, wait 30 days, and the lien filing may land past the deadline. At that point, the right to lien is gone.
What to Do If You Receive One
Receiving a notice does not mean a lien has been filed. Nothing has been recorded against the property yet. The clock is running, though, and ignoring the notice is the worst possible response.
Start by verifying the claim. Did the claimant actually perform work or deliver materials to the property? Is the amount accurate? If you hired a general contractor, call them right away. In many cases the owner has already paid the general contractor for the work in question, and the problem is that money has not flowed down to the subcontractor or supplier. That is a dispute between the general contractor and the sub, but a mechanic’s lien attaches to your property regardless of who is at fault in the payment chain.
If the claim is valid and you can resolve it, paying the claimant directly is the fastest way to prevent a lien. In some states, owners can deduct amounts paid directly to subcontractors from what they owe the general contractor. This takes careful documentation and, ideally, legal guidance so the payment is properly credited.
If you believe the claim is inflated or invalid, put your objections in writing and send them to the claimant before the notice deadline expires. Document everything. If the claimant files a lien you believe is unjustified, that paper trail is what you will use to challenge it. An attorney experienced in construction law can help evaluate the claim and identify defenses.
What Happens If the Deadline Passes
When the notice period expires without payment, the next step is filing the actual mechanic’s lien with the county recorder’s office in the county where the property sits. Unlike the notice, a recorded lien is a public record. It attaches to the title and shows up in title searches, which interferes with the owner’s ability to sell or refinance.
Filing is not the end of the process. A mechanic’s lien is only as useful as the claimant’s willingness to enforce it. Most states require the claimant to file a foreclosure lawsuit within a set period after recording. Miss that window and the lien expires and can be removed from the title.
Owners who want to clear a lien from their title before the lawsuit plays out can often bond off the lien by posting a surety bond with the court. The bond substitutes for the property as security, freeing the title while the underlying payment dispute continues. The bond amount is typically set at 125% or 150% of the lien amount, depending on the state. Once the bond is accepted, the lien is released from the property, and any recovery comes from the bond rather than a forced sale.
The Risk of Filing Without a Legitimate Basis
The notice process exists partly to deter frivolous or fraudulent liens. A property owner whose title is clouded by a baseless lien can sue for slander of title, a claim that someone published a false statement about ownership of real property that caused financial harm.
Damages can be substantial. Courts may award the difference in market value caused by the wrongful lien, plus attorney’s fees and litigation costs incurred to clear the title. Where fraud or malicious intent is shown, punitive damages may also be available. Some states impose additional statutory penalties for knowingly filing a fraudulent lien.
The notice and lien process is built for situations where work was performed, materials were delivered, and payment was not made. Using it as a pressure tactic on a debt that is genuinely in dispute can turn a payment problem into a much more expensive lawsuit, with the claimant on the wrong end of it.
