A notice of intent to lien is a formal warning that you are about to record a mechanic's lien unless you are paid, and it is often the cheapest move that actually works. It sits between your polite reminders and the lien itself. It tells the owner and the GC, in writing, that the lien is coming, names the amount, and gives them a short deadline to pay. Because a recorded lien clouds the title and can stall a sale or a loan, that warning alone shakes the money loose on a huge share of jobs, with no filing fee and no fight. In some states you are required to send one before you can record a lien at all. In others it is optional, but smart.
The thing that trips people up is that this is a different document from the preliminary notice, and different again from the lien. Get the three straight and you will use each one at the right moment.
The three notices, so you never mix them up
- The preliminary notice goes out at the very start of the job. It is not a threat and it is not about a dispute. It just preserves your right to file a lien later. See The preliminary notice explained.
- The notice of intent to lien goes out when a payment has gone bad and you are getting ready to record. It is the warning shot: pay me by this date or the lien gets filed.
- The lien itself is the actual claim you record with the county. It is the thing the intent notice is threatening.
Send them in that order over the life of a job, and each does its own job.
Why it works so well
A notice of intent to lien is leverage without the cost. Recording a real lien takes a filing fee, careful paperwork, and it puts a permanent mark on the title. But the threat of one, delivered in a formal, dated letter, often does the same work for free. The owner or GC now knows you understand the process, you are serious, and the clock is real. Many pay rather than let a lien land on the property, especially if they have a sale, a refinance, or a draw from the lender pending. You have given them a clean, quiet way to settle before it becomes public record.
Even when it does not get you paid on its own, it is not wasted. It becomes another dated page in your paper trail, and it shows you acted in good faith and gave fair warning before filing.
When your state requires one
Here is where it stops being optional. Several states will not let you record a lien unless you first serve a notice of intent, a set number of days before you file. Miss that step in one of those states, and the lien you file can be thrown out, even though the work was done and the money is owed. Some states also require the notice to be notarized, or served a specific way. Whether your state requires a notice of intent, how many days ahead it has to go out, and how it must be delivered are all state-specific. Confirm them in Working in Your State and the Mechanic's Lien Deadline tool before you count on skipping it or relying on it.
What to put in it
Keep it plain, formal, and complete:
- Both parties' full legal names and addresses, yours and the owner's, plus the GC if one hired you.
- The property, by address and, where you can, its legal description.
- The job and the amount owed, itemized so there is no argument about the number.
- A firm deadline to pay, a real date, not "soon."
- A clear statement that you will record a mechanic's lien against the property if payment is not received by that date.
Send it in a way you can prove, certified mail with a return receipt or a process server, and keep the proof with the rest of the job file.
Time it against your real deadline
A notice of intent buys pressure, but it does not pause your lien clock. The deadline to record the lien keeps running while you wait for them to respond. So do not send an intent notice so late that the reply deadline you set runs past your actual filing deadline. Work backward: know the last day you can record the lien in your state, then send the intent notice far enough ahead that you can still file on time if they ignore it. Get that filing deadline from the Mechanic's Lien Deadline tool.
Common questions
What is a notice of intent to lien?
It is a formal written warning that you will record a mechanic's lien against a property unless you are paid by a set deadline. It sits between your reminders and the lien itself, naming the amount owed and a firm date to pay. Because a recorded lien can stall a sale or a loan, the warning alone gets many jobs paid with no filing fee. In some states it is a required step before you can record a lien.
Is a notice of intent to lien the same as a preliminary notice?
No, they are two different documents sent at different times. A preliminary notice goes out at the start of the job to preserve your right to lien, with no dispute involved. A notice of intent to lien goes out later, once a payment has gone bad, to warn that you are about to record the lien. The lien itself is a third, separate step. Knowing which is which keeps you from missing one.
Do I have to send a notice of intent before filing a lien?
In some states yes, in others no. Several states will not let you record a lien unless you first serve a notice of intent a set number of days ahead, and skipping it there can get your lien thrown out. Other states make it optional. Whether your state requires one, and how much lead time it needs, is state-specific, so confirm it in Working in Your State before you rely on either answer.
Does sending a notice of intent to lien stop my deadline?
No. Your deadline to record the lien keeps running while you wait for a reply. The notice buys pressure, not time. Set the pay-by date early enough that, if they ignore it, you can still record the lien before your state's filing deadline passes. Work backward from that filing deadline, which you can get from the Mechanic's Lien Deadline tool.
The honest bit
- Whether your state requires a notice of intent before you can lien, how many days ahead it must go, and whether it must be notarized are all set state by state. This guide teaches the concept and the timing logic. Confirm your state's rules in Working in Your State and get your filing deadline from the Mechanic's Lien Deadline tool.
- This is general guidance, not legal advice. For a large or contested balance, a construction attorney can send an intent notice that carries more weight and make sure it is timed correctly against your lien deadline.
