What Is a Construction Payment Demand Letter?
A demand letter is a formal written request for payment of a specific past-due amount, sent before you escalate to a lien, a bond claim, or a lawsuit. In construction it is usually sent by the party at the bottom of a broken payment chain: a subcontractor the GC has not paid, a supplier the sub has not paid, a GC the owner has not paid, or an equipment lessor whose rental invoices are aging out. The letter does three jobs. It tells the debtor exactly what is owed and why, so a dispute (if there is one) surfaces now instead of in litigation. It sets a deadline. And it states a concrete next step, which turns an unpaid invoice into a risk the debtor has to manage. Owners and lenders do not want liens on title, and GCs do not want bond claims on their surety’s desk, so the letter goes to the people who feel that risk. A demand letter is different from a preliminary notice . A preliminary notice is sent at the start of a job, often before anything is late, to preserve lien rights. A demand letter is sent after payment is late. In many states both matter: the preliminary notice is what makes your later demand credible, because it is what keeps your lien right alive.
Is a Demand Letter Legally Required Before a Mechanics Lien?
Not in most states. An informal demand letter is optional everywhere. But a group of states requires a statutory pre-lien notice that does the same work as a demand, with mandatory contents, a mandatory recipient list, and a mandatory service method. In these states, skipping the statutory notice can defeat the lien, and a regular demand letter does not count as a substitute unless it meets every requirement of the statute. State Required notice Timing Statute {statutoryNotices.map((row) => ( ))} The three that function most like a demand are Colorado, Pennsylvania, and Wisconsin, because each requires the notice a set number of days before the lien can be recorded or filed. That waiting period gives the owner and contractor a last chance to pay, and it has to fit inside your recording deadline. Connecticut, Kentucky, and Tennessee tie their notices to your furnishing dates instead, so the notice is due whether or not you have started collection. This table covers the notices we have verified on our state guides; it is not a complete list of every pre-lien requirement in the country. Many other states require a preliminary notice at the start of a job. Check your state on the 50-state lien law directory and in Preliminary Notice Requirements by State .
When Should You Send a Demand Letter?
Send it as soon as payment is clearly late and informal follow-ups have failed, and always with enough runway to act on it. Work backward from your deadlines: 7–15 days to pay is the usual window in a construction demand letter 0 days of extension a demand letter adds to your lien deadline 30 days of required notice before filing in Pennsylvania (subs) and Wisconsin Find your lien recording deadline from your last furnishing or completion date. On a public job, find your bond claim notice deadline instead. Subtract any statutory notice period your state requires before recording (10 days in Colorado, 30 in Wisconsin and for Pennsylvania subs). Subtract a week to prepare, sign, notarize if required, and record the lien. Set the letter’s payment deadline before that date , and mail the letter at least 7 to 15 days before it. If the math does not work because your deadline is too close, do not send a demand and wait. Record the lien first, then send the demand with a copy of the recorded lien attached. A recorded lien is a stronger letter than any letter.
What to Include in a Construction Demand Letter
A demand letter works when the reader can check every fact in it in five minutes. Include: Your company’s full legal name and contact person , and the debtor’s full legal name (from the contract, not the truck door). The project — name, street address, and owner. On a private job, include the parcel or legal description if you have it; you will need it for the lien. The property search tool finds owner and parcel data. The contract or purchase order — date, number, and scope, plus any approved change orders. An itemized balance — each invoice or pay application by number, date, and amount, less payments received. List retainage separately. If you are claiming interest, list it separately with its source (contract clause or statute). A firm payment deadline — a calendar date, not “within a reasonable time.” The specific next step and its date — for example, recording a mechanics lien against the property, making a claim on the payment bond, or stopping work where your state allows it after notice. Payment instructions — where to send the check or wire, so “we didn’t know where to pay” is off the table. A copy list — everyone else receiving the letter. Copying the owner and the surety is often what gets the GC to pay. Keep it to one or two pages, attach the unpaid invoices and pay applications, and keep the tone flat. A demand letter will likely be read later by a judge, so write

Who Should Receive the Demand Letter?
Address it to the party you contracted with, because that is who legally owes you. Then copy everyone whose money or property is at risk if you escalate: The property owner on a private project. The owner is the one whose title a lien clouds. In Florida and Illinois, an owner who has received a claimant’s statutory notice must pay that claimant out of the contractor’s money (Fla. Stat. § 713.06(3); 770 ILCS 60/27), so the owner has a direct reason to act. The general contractor , if you are a sub-sub or a supplier to a sub. The GC usually controls the next check. The surety on a bonded project. Get the bond number from the GC or the public agency. A demand copied to the surety tells the GC its bonding line is now involved. See Mechanics Lien vs. Bond Claim . The construction lender , if you know who it is. Lenders hold the draw money and do not fund draws over unresolved liens. Copying parties up the chain also sets up a joint check or direct-payment solution, which is often how these disputes end. See Joint Check Agreements by State .
What Leverage Can a Demand Letter Point To?
The letter is only as strong as the remedy behind it. Name the one that applies to your project: Mechanics lien (private projects) The strongest point of leverage, because it puts the owner’s title at risk. It only works if your notices were timely and the recording deadline has not passed. See what a mechanics lien is and what happens after you file . Payment bond claim (public projects) Public property cannot be liened. On federal jobs the Miller Act gives second-tier claimants 90 days from last furnishing to notify the prime contractor, and suit is due within one year (40 U.S.C. § 3133(b)). State public jobs run on Little Miller Acts. See Little Miller Act deadlines by state . Prompt payment interest Every state but New Hampshire charges interest on late public-project payments. Some rates are steep: 2 percent a month to lower-tier subs in Illinois, and 0.5 percent a day (capped at 15 percent) against a withholding prime in Louisiana and Mississippi. See Prompt Payment Laws by State . Stopping work Only 15 states give a statutory right to stop work for nonpayment; elsewhere your contract controls, and walking off can put you in breach. Check before you threaten it: The Right to Stop Work for Nonpayment by State .
What to Do If the Demand Letter Is Ignored
Do exactly what the letter said, on the date it said. Debtors notice whether a claimant follows through, and a missed threat makes the next one worthless. In order: Record the lien or serve the bond claim before its deadline. Build it in the lien generator with The Mechanics Lien Management Method, which walks through each state’s required contents and service steps. Serve the recorded lien on the parties your state requires, within its post-recording deadline. Calendar the enforcement deadline. A lien that is not foreclosed in time expires. See the mechanics lien foreclosure process . Talk to a construction attorney about a breach of contract claim, attorney fees, and whether suit on the lien, the bond, or the contract recovers the most. You can connect with a licensed construction attorney through the Mechanics Lien Management attorney network.
6 Demand Letter Mistakes That Cost Contractors Money
1. Waiting on the letter past the lien deadline The most expensive mistake. A demand letter extends nothing. Miss the deadline and you lose your lien rights entirely. 2. Treating a demand letter as your statutory notice In Colorado, Pennsylvania, Wisconsin, and the other notice states, the statute dictates contents, recipients, and delivery. An informal letter that misses one element may not count. 3. Inflating the amount Demand only what is owed under the contract, with interest and fees broken out. Rolling disputed or unearned amounts into the balance invites a counterclaim, and an overstated lien can be invalid in some states. 4. Threatening a remedy you don’t have A lien threat on a public school, or a stop-work threat in a state with no statutory right, tells the debtor you have not checked your rights. 5. Sending it only to your customer The sub that is not paying you may have no money. The owner, lender, and surety do. Copy them. 6. Signing an unconditional waiver to get a partial check If the response is “sign this waiver and we’ll pay,” give a conditional waiver for the amount actually paid. See lien waivers explained and Lien Waiver Mistakes .
Frequently Asked Questions
What is a construction payment demand letter?
A construction payment demand letter is a written notice from an unpaid contractor, subcontractor, supplier, or equipment lessor to the party that owes it money. It states the project, the amount past due, the invoices or pay applications behind it, a firm deadline to pay, and what the claimant will do if payment does not arrive, such as recording a mechanics lien, making a payment bond claim, stopping work where the law allows it, or filing suit. It is the cheapest collection step available and creates a dated record of the demand.
Is a demand letter required before filing a mechanics lien?
In most states, no. An informal demand letter is optional. But several states require a statutory notice that works like a demand before you can record or enforce a lien. Colorado requires a Notice of Intent served on the owner and prime contractor at least 10 days before recording (C.R.S. 38-22-109(3)). Wisconsin requires a notice of intent at least 30 days before filing the lien claim (Wis. Stat. 779.06(2)). Pennsylvania requires a subcontractor to serve a formal notice at least 30 days before filing (49 P.S. 1501). Those statutory notices have required contents and service methods, and an ordinary demand letter does not replace them.
Does sending a demand letter extend my mechanics lien deadline?
No. A demand letter is not a lien filing and does not pause or extend any notice, recording, or enforcement deadline. The lien recording clock keeps running from your last furnishing date or completion date, depending on the state. If the deadline in the letter falls after your lien deadline, you will lose the lien while you wait. Set the payment deadline in the letter so you still have time to record if the money does not come.
How long should I give them to pay in a demand letter?
Most construction demand letters give 7 to 15 days. The right number depends on your lien deadline. Count back from the last day you can record your lien, leave at least a week to prepare and record it, and set the letter's deadline before that. If your lien deadline is less than two weeks away, skip the waiting period and record the lien, then send the demand with a copy of the recorded lien.
Should I send a demand letter by certified mail or email?
Send it both ways. Certified mail with return receipt requested gives you proof of delivery and a date that holds up in court, and many statutory notices require registered or certified mail or personal service. Email gets it read the same day. Keep copies of the letter, the mailing receipt, the green card or tracking record, and the email. If your state's statute prescribes a delivery method for a pre-lien notice, follow the statute exactly.
Can I add interest or late fees to a construction demand letter?
You can demand interest if your contract provides for it or a statute gives it to you. On public projects, every state but New Hampshire has a prompt payment statute that charges interest on late payments; Illinois charges 2 percent a month on late payments to lower-tier subcontractors on public work, and Louisiana and Mississippi charge 0.5 percent a day up to a 15 percent cap against a prime contractor that withholds a subcontractor's money. Demand only what you can support. Overstating the amount in a lien can invalidate it in some states, so keep interest and fees separately itemized.
What happens if they ignore my demand letter?
Move to the next remedy before your deadlines run. On a private project, record your mechanics lien on time and then enforce it within the state's foreclosure deadline. On a public project, where you cannot lien, make your payment bond claim under the federal Miller Act or your state's Little Miller Act. You can also sue for breach of contract, and in 15 states you may have a statutory right to stop work after notice. A licensed construction attorney can tell you which path recovers the most for your claim.
