When a property owner won't pay a contractor, you have four enforceable options: send a formal demand letter, file a mechanics lien against the property, initiate a payment bond claim (on bonded public or private projects), or pursue the debt in small claims or civil court. The right move depends on whether you protected your lien rights upfront—specifically, whether you served a preliminary notice (also called a Notice to Owner or Notice of Right to Lien, depending on the state) before or shortly after you started work. Miss that deadline and your lien rights may be partially or fully forfeited, leaving you with demand letters and litigation as your only tools. Each option has hard deadlines, so act immediately.
What Should You Do First When a Property Owner Isn't Paying?
Stop work and document everything before you take any other action. Pull your contract, your invoices, your change orders, and any written communications—texts, emails, job site notes. You need a paper trail that clearly shows what was owed, what was delivered, and when payment was due.
Then check two things:
- Did you serve a preliminary notice? Most states require subcontractors and suppliers to serve a preliminary notice within 20 days of first furnishing labor or materials to preserve mechanics lien rights. If you skipped that step, your options narrow immediately.
- What does your contract say about payment terms and dispute resolution? Some contracts require mediation before litigation. Others have pay-when-paid clauses that shift timing (though not always final liability) to the GC.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days—up from 49% just two years earlier. You are not alone, and there are tested tools to handle this. Use them in order.
How Does a Demand Letter Work in a Contractor Payment Dispute?
A demand letter is a written notice to the property owner that formally states the amount owed, the basis for the debt, and a deadline to pay before you escalate. It is not a lawsuit—but courts treat it as evidence that you attempted resolution before filing.
A strong demand letter to a property owner includes:
- Your full legal business name and license number
- The property address and project description
- The specific dollar amount owed, broken down by invoice
- The contract clause or state statute that establishes the payment obligation
- A firm payment deadline (10–14 days is standard)
- A clear statement of what you will do next: file a mechanics lien, pursue arbitration, or take the matter to court
Send it via USPS Certified Mail with Return Receipt so you have proof of delivery. Keep a copy. If the owner ignores the letter, that silence strengthens your position in court or in a lien foreclosure action.
A demand letter alone rarely recovers money from a determined nonpayer. Think of it as required groundwork—proof that you put the owner on notice—while you simultaneously prepare your lien filing.
What Is a Mechanics Lien and How Does It Force Payment?
A mechanics lien is a legal claim recorded against a property's title that prevents the owner from selling or refinancing until the debt is resolved. It is the most powerful collection tool available to contractors and subcontractors, and it works because it threatens the one thing every property owner values: clear title.
Here is how the process works in sequence:
- Preliminary notice (if required): Most states require this before you can lien. Deadlines range from 20 days after first furnishing (California, Arizona, Nevada) to the start of work or shortly after (Florida, Washington, Oregon). Miss it and you may lose lien rights entirely.
- Lien filing: After a payment default, you file the lien with the county recorder or clerk where the property is located. Deadlines for filing vary—90 days after last furnishing in California (Cal. Civ. Code § 8412), 90 days in Florida (Fla. Stat. § 713.08(5)), 120 days in Arizona (A.R.S. § 33-993), and so on.
- Lien foreclosure: If the owner still does not pay after the lien is recorded, you can sue to foreclose the lien—forcing a court-ordered sale of the property to satisfy the debt. Most owners pay before it reaches foreclosure.
A recorded lien also creates immediate leverage. Owners who are in the middle of refinancing or selling have strong incentive to pay fast because a lien clouds their title and kills deals.
What If You Missed the Preliminary Notice Deadline?
If you failed to serve a preliminary notice, your mechanics lien rights may be limited or eliminated, depending on the state. This is the most common and most costly mistake in construction payment disputes.
Here is what the statute says in key states:
- California: Under Cal. Civ. Code § 8200, a subcontractor who serves a preliminary notice late still retains lien rights—but only for work performed in the 20 days before service. Everything before that window is unprotected. No notice at all bars lien rights entirely on private works.
- Florida: Under Fla. Stat. § 713.06(2)(c), a subcontractor who fails to serve a Notice to Owner before the owner pays the general contractor in full loses the right to lien that payment. Timing is everything.
- Arizona: Under A.R.S. § 33-992.01, subcontractors must serve a preliminary 20-day notice. Failure to do so is a complete bar to lien rights.
- Washington: Under RCW 60.04.031, subcontractors must serve a Notice to Customer before the first day of furnishing—or within 10 days after—to preserve lien rights.
If you missed the deadline, shift immediately to your remaining options: demand letter, small claims court, civil suit, or negotiation. You can still recover the debt—you just lost your most powerful leverage tool.
Can You File a Payment Bond Claim Instead of a Lien?
On bonded projects, a payment bond claim is often faster and more reliable than a mechanics lien. On federal public projects, the Miller Act (40 U.S.C. § 3131) requires prime contractors to post a payment bond, and first-tier subcontractors must give written notice to the prime within 90 days of last furnishing to preserve their bond claim rights. State "Little Miller Acts" apply similar requirements to state and local public projects.
Private projects can also be bonded. Check your subcontract—if the GC posted a payment bond, you can file a claim against that bond without touching the property's title.
Bond claims have their own deadlines, often separate from lien deadlines. On federal projects, bond claimants who do not have a direct contract with the prime contractor must serve written notice within 90 days of last furnishing under 40 U.S.C. § 3133(b)(2). Missing this deadline eliminates the bond claim.
What Are Your Options in Small Claims or Civil Court?
Small claims court is available when the amount in dispute falls below your state's threshold—typically $5,000 to $25,000 depending on jurisdiction. It is relatively fast, requires no attorney (though you can bring one in some states), and is well-suited for straightforward disputes over completed work and unpaid invoices.
For larger amounts, civil court litigation is the path. You file a civil complaint alleging breach of contract, and if you prevail, the court enters a judgment. A judgment can be enforced through wage garnishment, bank levies, or liens on other property the owner holds.
Practical considerations before you sue:
- Attorney fees: Unless your contract or state statute provides for fee-shifting, you pay your own attorney. Factor this into whether litigation is worth it.
- Collectability: A judgment against an owner who has no assets is a piece of paper. Before filing suit, confirm the owner has property, business assets, or receivables you can reach.
- Statute of limitations: Written contract claims typically carry a 4–6 year statute of limitations depending on the state. Oral contract claims are shorter. Do not sit on a dispute—the clock runs from the date of breach.
How Do Pay-When-Paid and Pay-If-Paid Clauses Affect Your Claim?
These clauses appear in subcontracts and shift payment timing—or in the worst case, payment risk—from the GC to you.
- Pay-when-paid: The GC pays you when it receives payment from the owner. Courts in most states treat this as a timing clause only—the GC still owes you eventually, regardless of whether the owner pays. It delays your right to sue but does not eliminate it.
- Pay-if-paid: This clause attempts to shift the entire risk of owner nonpayment to the subcontractor. Enforcement varies sharply by state. California (Cal. Bus. & Prof. Code § 7108.5) and several other states have enacted statutes that limit or invalidate pay-if-paid clauses. In states that enforce them, if the owner never pays the GC, the GC may owe you nothing.
Read your subcontract before you sign—and before you dispute. If you have a pay-if-paid clause, your claim may be against the GC's insurer or bonding company rather than the owner directly.
What Steps Should You Take in the Right Order?
Work through these steps in sequence. Do not skip to litigation before exhausting the tools that cost less.
- Day 1–3: Compile documentation. Gather your contract, all invoices, change orders, delivery receipts, lien waiver records, and any owner communications.
- Day 3–5: Send a formal demand letter via Certified Mail. Set a 10–14 day payment deadline.
- Simultaneously: Verify your preliminary notice status and calculate your lien filing deadline. Use your state's statute to confirm the exact window.
- If the deadline allows: File your mechanics lien. Do not wait for the demand letter deadline to expire if your lien window is closing.
- After lien filing: Notify the owner in writing that the lien has been recorded and that you will pursue foreclosure if payment is not received within 30 days.
- If still unpaid: Consult a construction attorney about lien foreclosure or civil litigation, depending on the amount in dispute.
According to the Rabbet 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. Owners who delay payment are benefiting from your float. Stop letting them.
Frequently Asked Questions
Can a subcontractor lien a property directly when the owner won't pay?
Yes. Subcontractors have direct lien rights against the property in every U.S. state, even without a direct contract with the owner. The requirement is that you must have served a valid preliminary notice (where required by state law) and file your lien within the statutory deadline after last furnishing labor or materials.
What is the fastest way to get paid when a property owner refuses to pay?
A recorded mechanics lien combined with a formal demand letter is typically the fastest path to payment short of litigation. Owners who are selling or financing the property have immediate incentive to clear the lien. Bond claims on bonded projects can also resolve quickly because the surety has an independent obligation to investigate and pay valid claims.
Does a demand letter have to come from an attorney?
No. A demand letter from a contractor carries legal weight as long as it clearly states the amount owed, the basis for the claim, and a response deadline. However, a letter on attorney letterhead may prompt faster response. For amounts over $25,000–$50,000, having an attorney draft or review the letter is worth the cost.
What happens if an owner files for bankruptcy after I lien the property?
A recorded mechanics lien generally survives a bankruptcy filing and retains its priority position against the property, subject to the lien's priority date under state law. The automatic stay in bankruptcy prevents you from foreclosing the lien without court permission, but the lien itself remains attached to the property. Consult a construction attorney immediately if a liened owner files bankruptcy.
How long does a mechanics lien stay on a property?
It depends on the state. In California, a lien is effective for 90 days after recording, after which you must file a lien foreclosure lawsuit or the lien expires (Cal. Civ. Code § 8460). In Florida, a lien expires one year after recording unless a lawsuit to enforce it is filed (Fla. Stat. § 713.22). In Arizona, the foreclosure action must be filed within six months of the lien (A.R.S. § 33-998).
Can I lien a property if I only supplied materials and didn't perform labor?
Yes. Material suppliers have mechanics lien rights in all U.S. states, subject to the same preliminary notice requirements as labor subcontractors. The delivered materials must have been permanently incorporated into the project (or intended for incorporation) to qualify.
What if the owner claims the work was defective and refuses to pay on that basis?
A defect claim by the owner does not automatically eliminate your right to payment. If your work substantially complied with the contract, you are generally entitled to the contract price less any provable damages caused by defects. Document your work thoroughly—inspection reports, photos, job logs—and respond to any defect claims in writing, requesting specifics. Do not accept a broad defect allegation as a valid reason to forfeit your entire invoice.
Is it worth filing a mechanics lien on a small job?
Yes, in most cases. A single preliminary notice costs $24.99 through LienFlash. If it preserves lien rights on a $15,000 subcontract that would otherwise go unpaid, the math is straightforward. The real question is whether you set up lien rights before the dispute arose—because you cannot file an effective lien without them.
