If you supply labor or materials on a bonded construction project, getting paid depends on more than doing good work and sending a fair invoice. It often depends on a single piece of paperwork: the payment bond subcontractor claim notice. Miss it, and you can lose your right to collect. Even if every dollar you’re owed is legitimate.
This guide walks through what that notice is, who has to send one, the deadlines that matter, and how to protect your claim from the mistakes that sink so many legitimate payment disputes.
What Is a Payment Bond Subcontractor Claim Notice?
A payment bond subcontractor claim notice is a formal written warning. It tells the general contractor and the surety company that you haven’t been paid for labor or materials on a bonded project.
It’s not a lawsuit. It’s not even a formal bond claim yet. It’s a preliminary step that preserves your legal right to file one later if payment doesn’t come through.
Payment bonds exist because subcontractors and suppliers often have no direct contract with the property owner. On public projects, you also can’t put a mechanic’s lien on government-owned property. The payment bond is the fallback protection instead. But sureties and general contractors can’t track every sub-tier relationship on a job site. The notice requirement forces you to identify yourself early, so everyone knows who is owed money and how much.
Why Notice Requirements Exist on Bonded Projects
Without a notice rule, a surety could face claims from parties it never knew existed, long after a project wrapped up. Notice requirements give the general contractor a chance to fix payment problems before they escalate. They also create a paper trail. That trail proves when work was performed and when a payment dispute began.
For subcontractors, this cuts both ways. The rule protects your right to get paid. But silence can cost you that right, no matter how strong your underlying claim is.
Public vs. Private Project Differences
On federal construction projects, payment bond rights come from the Miller Act. That’s a federal law requiring general contractors to post payment bonds on most contracts over a set dollar threshold. Most states have adopted their own version, often called a “Little Miller Act,” to cover state and local public projects. Private bonded projects, meanwhile, are governed by the terms of the specific bond and by state statute. Those rules vary a lot from state to state.
The core idea stays the same across all three: if you don’t have a direct contract with the general contractor, you likely need to send preliminary notice to protect your claim. But the deadlines, required content, and delivery rules can differ sharply depending on whether the project is federal, state, or private.
Who Must Send a Payment Bond Claim Notice
Not every subcontractor needs to send a preliminary notice. The requirement generally hinges on your position in the contract chain.
If you have a direct contract with the general contractor, meaning the GC hired you personally, you typically don’t need to send preliminary notice before making a bond claim. The general contractor already knows you’re on the job and what you’re owed.
If you don’t have that direct relationship, notice usually becomes mandatory.
First-Tier vs. Second-Tier Subcontractors and Suppliers
Construction contracts work in tiers. A first-tier subcontractor contracts directly with the general contractor. A second-tier subcontractor or supplier contracts with a first-tier sub instead.
Say a general contractor hires a framing subcontractor. That framing sub then hires a lumber supplier. The lumber supplier has no direct contract with the general contractor, so the GC may not even know the supplier is furnishing materials on the job. That’s exactly the gap preliminary notice is designed to close.
If you’re a second-tier sub or supplier, assume you need to send notice unless you’ve confirmed otherwise with the bond terms or applicable statute.
Payment Bond Claim Notice Deadlines You Can’t Miss
Deadlines are where most legitimate claims fall apart. Even a well-documented, fully justified payment dispute can become unenforceable once the notice window closes.
Federal Projects: The 90-Day Rule
On most federal projects, subcontractors without a direct contract with the prime contractor generally must send preliminary notice within 90 days of last furnishing labor or materials to preserve their Miller Act bond rights. That clock starts from the last date you actually worked or delivered materials, not from your invoice date, and not from the project’s completion date.
Consider a drywall subcontractor working on a public school project. The sub assumes the general contractor will “handle” notifying the surety, since the GC has always been reasonable to work with. Ninety days pass. The invoice is accurate, the work is complete, and the amount owed is undisputed. But the notice window has closed, and the subcontractor has lost the right to claim against the payment bond entirely. This scenario plays out often enough on Miller Act and Little Miller Act projects that it’s one of the most common and preventable disputes in construction payment law.
State and Private Project Variations
State and private bonded projects don’t follow one uniform rule. Some states mirror the 90-day federal standard. Others set shorter or longer windows, and some tie the deadline to specific milestones like substantial completion.
Because these variations are so significant, don’t assume your state matches the federal rule. Pull the actual bond document. Check your state’s Little Miller Act statute, or applicable private bond terms, before you assume you have more time than you actually do. If you’re already tracking other project compliance documents, it helps to review contractor liability insurance requirements by state at the same time you’re confirming notice deadlines, since both often hinge on the same state-specific rules.
How to Write and Send a Payment Bond Claim Notice
A valid notice doesn’t need to be complicated, but it does need to be complete and precise. Vague language is one of the fastest ways to get a notice challenged or rejected outright.
Required Information to Include
At minimum, your notice should include:
- The project name and location
- The payment bond number, if you have it, or the surety’s name
- The general contractor’s name and contact information
- Your company’s name and role on the project
- A clear description of the labor or materials you provided
- The exact amount owed
- The last date you furnished labor or materials
- A clear statement that you’re claiming rights against the payment bond
Avoid rounding the amount owed or describing your work in general terms. “Approximately $40,000 for framing work” is weaker than an itemized figure tied to specific invoices and dates.
Best Delivery Methods for Proof of Notice
How you send the notice matters as much as what it says. Construction attorneys commonly advise subcontractors to send notice by certified mail with return receipt requested, or another trackable delivery method, the moment payment becomes overdue rather than waiting until the relationship has fully soured.
Trackable delivery options include:
- Certified mail with return receipt requested
- Registered mail
- Courier delivery with a signed proof of delivery
- Process server delivery, for high-value or high-conflict disputes
Whatever method you choose, keep copies of everything: the notice itself, the delivery receipt, and any related correspondence. If your claim ever ends up in front of a surety’s legal team or a judge, this documentation is your evidence that notice went out correctly and on time.
Common Mistakes That Invalidate a Subcontractor Claim Notice
A payment bond claim notice can fail for reasons that have nothing to do with whether you’re actually owed money. Missed deadlines and vague notice language are two of the most frequent reasons legitimate payment bond claims get rejected, based on how these disputes typically play out.
Missing Deadlines and Weak Documentation
The most common mistakes include:
- Sending notice late. Even one day past the deadline can invalidate the claim on many bonded projects.
- Using vague dollar amounts. “Money owed for services rendered” won’t hold up like a specific, itemized figure.
- Failing to prove delivery. Regular mail with no tracking gives you no way to prove the GC or surety actually received it.
- Confusing preliminary notice with a formal bond claim. Sending notice is step one. It is not the same as filing the actual bond claim or lawsuit, which usually has its own separate deadline.
- Assuming someone else will handle it. As the drywall subcontractor example shows, waiting on a general contractor to notify the surety on your behalf is a common and costly error.
Before you send anything, it’s worth comparing your bonded work against the other documentation you’re already tracking. Many subcontractors managing payment bond deadlines are also handling certificate of insurance requirements on construction projects, and it’s easy to let one compliance deadline slip while focused on another.
What Happens After You Send the Notice
Sending notice doesn’t guarantee payment. It preserves your right to pursue payment through the bond if the general contractor still doesn’t pay.
Once notice is sent, give the general contractor a reasonable window to respond. Many disputes resolve at this stage once the GC or surety realizes a formal claim is coming. Some don’t.
Filing a Formal Bond Claim or Lawsuit if Payment Still Isn’t Made
If payment doesn’t arrive after notice, the next step is filing a formal payment bond claim with the surety. This is a distinct filing from the preliminary notice, and it typically has its own deadline. That deadline is often measured in months from your last date of furnishing labor or materials, separate from the 90-day notice window on federal projects.
If the surety denies the claim or doesn’t respond, your next option is usually a lawsuit against the bond itself. That also carries a strict statute of limitations depending on the project’s jurisdiction. This is a good point to bring in a construction attorney, particularly if the amount owed is significant or the surety is disputing the claim’s validity. An attorney can also help you determine whether a state’s broader limitations rules, similar to those used to evaluate a statute of limitations for insurance lawsuits by state, might affect how long you have to act.
If you believe a surety is delaying or denying a valid claim without proper justification, it’s also worth understanding your options for filing a bad faith commercial insurance lawsuit, since some of the same principles around unreasonable claim denial can apply to bond disputes.
Getting stiffed on a construction project doesn’t just hurt your cash flow on one job. It can threaten the financial stability of your business. That’s why it pays to think beyond a single claim and consider broader asset protection strategies for business owners who regularly take on bonded work.
Payment bond rules exist to protect subcontractors and suppliers who do the work but sit outside the general contractor’s direct contract. That protection only works if you assert it correctly and on time. If you’re approaching a deadline, or you’ve already sent notice and still haven’t been paid, don’t wait to find out whether your claim is still valid. Use a payment bond claim notice checklist to confirm you’ve covered every requirement, and talk to a construction attorney before your statutory window closes for good.
