When a GC won't pay final payment, your fastest and most powerful tool is a mechanics lien — a legal claim recorded against the property title that forces the issue into the open, because no owner or lender can ignore a cloud on title. Most states give subcontractors 60 to 90 days from project completion or last furnishing date to record a lien, but preserving that right almost always requires a preliminary notice filed earlier in the job. If you skipped the preliminary notice, your lien rights may already be gone. On top of the lien, you have demand letters, bond claims (on public jobs), and small claims or civil court as escalating options. The steps below work in sequence — start immediately, because deadlines are unforgiving.
Why Is the GC Withholding Final Payment?
A GC withholding final payment is not always acting in bad faith — but you need to know which situation you're in before you choose your response. The four most common reasons are: a legitimate dispute over punch-list items or workmanship, the owner hasn't paid the GC yet, the GC is cash-flowing other jobs with your money, or there's a paperwork bottleneck like a missing lien waiver or close-out document.
Ask the GC in writing — email or text — for the specific reason payment is being held. "When can I expect final payment, and what is preventing it from being released right now?" That question, in writing, creates a record. If the GC points to a punch list, get it in writing too. If they claim the owner hasn't paid, ask for a copy of their payment application to the owner. Vague non-answers are a red flag that the money problem is on their end, not the owner's. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days — so slow payment is the norm, but that doesn't make it legal or acceptable.
What Does Your Subcontract Say About Final Payment?
Your subcontract is the first document you need to read carefully, because it controls the payment terms, dispute resolution process, and any "pay-when-paid" or "pay-if-paid" provisions that affect your rights.
Pay-when-paid clauses make your payment contingent on the GC receiving money from the owner, but in most states this creates only a timing delay — not a permanent excuse to withhold. Pay-if-paid clauses are stronger and, if enforceable in your state, can actually shift the risk of owner non-payment to you. California, for example, generally disfavors pay-if-paid clauses as against public policy. Florida allows them if the language is explicit under Fla. Stat. § 713.06. Check your state.
Also look for: the deadline after substantial completion that triggers final payment, retainage percentage and release conditions, notice-of-claim requirements before you can file suit, and any mandatory mediation or arbitration clause. If your contract requires you to send a written notice of claim before pursuing legal remedies, skip that step and you may waive your right to collect.
How Do You Send a Final Payment Demand Letter?
A final payment demand letter is a formal written demand that states the exact amount owed, the basis for the debt, and the deadline for payment before you escalate to legal remedies. Send it before you file a lien — it often shakes payment loose without litigation, and it demonstrates good faith if you end up in court.
Your demand letter must include:
- Your company name and license number
- The project name, address, and job number
- The exact dollar amount owed, broken out as: unpaid contract balance + approved change orders + retainage being withheld
- The date payment was due per your contract
- A hard deadline for response — 7 to 10 business days is standard
- Notice that you will file a mechanics lien and pursue all available legal remedies if payment is not received
- Your signature and date
Send it via certified mail AND email. Certified mail creates proof of delivery that holds up in court. Keep the tracking receipt. If you are in Florida, California, Arizona, Nevada, Washington, or Oregon, you should already have a preliminary notice on file from early in the job — if you don't, your lien rights may be limited or gone.
What Happens If the GC Still Doesn't Pay After the Demand Letter?
If the GC still doesn't pay after your demand letter deadline passes, your next move is to file a mechanics lien — immediately, because state deadlines don't care about ongoing negotiations.
A mechanics lien is a legal encumbrance recorded against the real property. Once it's on title, the property owner cannot sell, refinance, or transfer clean title without resolving it. That pressure reaches the owner directly, which is why lien filings often produce payment faster than letters do. Here are typical lien recording deadlines for subcontractors (always verify your specific state statute):
| State | Deadline to Record Lien | Preliminary Notice Required? |
|---|---|---|
| California | 90 days after project completion | Yes — within 20 days of first furnishing |
| Florida | 90 days after last furnishing | Yes — within 45 days of first furnishing |
| Texas | 15th of 3rd month after unpaid work | Yes — specific monthly deadlines |
| Arizona | 120 days after project completion | Yes — within 20 days of first furnishing |
| Nevada | 90 days after project completion | Yes — within 31 days of first furnishing |
| Washington | 90 days after project completion | Yes — within 60 days of first furnishing |
| Oregon | 75 days after project completion | Yes — within 8 days of first furnishing |
If you missed your preliminary notice deadline, you may still have partial lien rights or other remedies — but talk to a construction attorney in your state before assuming you're out of options.
To calculate your exact lien filing deadline based on your state and first-furnishing date:
How Do You Handle Retainage That the GC Is Holding Back?
Contractor holding retainage past the legally required release date is a separate issue from general non-payment, and most states have specific retainage statutes with their own deadlines and penalties. Retainage is typically 5% to 10% of your contract value held back until substantial completion or final acceptance.
In Florida, retainage on private projects must be released within 30 days of the owner releasing final payment to the GC, under Fla. Stat. § 713.06(3)(c). Late payment of retainage triggers interest penalties. In California, the owner must release retainage within 60 days after project completion under Cal. Civ. Code § 8812. In Texas, Tex. Prop. Code § 28.001 et seq. governs retainage timing and interest on late payments.
Your mechanics lien claim should include the retainage amount. Do not waive retainage in a partial lien waiver unless you are being paid that amount simultaneously. A common GC tactic is to request a "final" lien waiver before releasing retainage — sign that only when the check clears, and make sure any waiver you sign is limited to amounts actually paid.

What Are Your Options on Public Construction Jobs?
On public jobs — federal, state, or municipal projects — mechanics liens against the property are not available because the government owns the land. Your equivalent tool is a payment bond claim.
The federal Miller Act (40 U.S.C. § 3133) requires prime contractors on federal projects over $150,000 to obtain payment bonds. State "Little Miller Act" equivalents apply to most state public works. As a first-tier subcontractor, you have a direct bond claim right. As a second-tier sub (sub to a sub), you typically must have served a preliminary notice on the prime contractor within 90 days of first furnishing on federal jobs.
To file a bond claim: obtain a copy of the payment bond (you have a legal right to request it), send a written notice of claim to the bonding company and the GC stating the amount owed, and file within the statute's deadline — typically 90 days after last furnishing on federal projects, with 1 year to file suit on the bond. Miss these windows and the surety can deny the claim entirely.
Can You Sue the GC for Unpaid Final Payment?
Yes — a subcontractor can sue a GC for unpaid final payment in civil court, and in many states you are entitled to recover attorney's fees and interest on top of the unpaid balance if you win.
In Florida, Fla. Stat. § 713.06(3)(g) provides for attorney's fees in construction payment disputes. California's prompt payment statutes (Cal. Civ. Code § 8800 et seq.) impose 2% monthly interest on late payments to subcontractors on private works. Texas Tex. Prop. Code § 28.004 provides for interest at 1.5% per month plus attorney's fees on late payments under the Prompt Payment Act.
For amounts under your state's small claims limit (typically $10,000–$25,000 depending on state), small claims court is faster and cheaper than civil litigation and doesn't require an attorney. For larger disputes, a construction attorney can often resolve the matter with a well-drafted demand before a lawsuit is ever filed. The mechanics lien, if properly recorded, gives you significant settlement leverage before trial.
According to Rabbet's 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. That number reflects the systemic pressure subcontractors are operating under — which is exactly why lien rights exist.
Check lien deadlines across all states where you work:
What Should You Do Right Now If the GC Won't Pay?
Act on all of the following in parallel — not in sequence — because deadlines run simultaneously.
- Pull your subcontract and read it today. Find the payment terms, notice requirements, and dispute resolution clause.
- Confirm your preliminary notice status. Did you file one at the start of this job? If not, check your state's rules on whether you can still file a late notice with partial effect.
- Send a written demand letter this week. Set a 7-day deadline. Certified mail plus email.
- Calculate your lien filing deadline. Use your first-furnishing date and your state's statute. Don't assume — verify.
- File your mechanics lien before the deadline. Don't wait for negotiations to conclude. You can always release the lien if you get paid. You cannot un-miss a deadline.
- Document everything. Photos of completed work, signed delivery tickets, approved change orders, text messages, emails — all of it.
- Consult a construction attorney if the amount justifies it. Most offer free or low-cost initial consultations. If your unpaid balance is over $10,000, the conversation pays for itself.
Frequently Asked Questions
Can a GC legally withhold final payment until the owner pays them?
It depends on your state and your contract. A "pay-when-paid" clause typically makes GC payment to you contingent on the GC receiving funds from the owner, but most courts treat it as a timing condition, not a permanent right to withhold. A "pay-if-paid" clause can shift owner non-payment risk to you, but these clauses must be explicit and are unenforceable in some states. Check your contract language and your state's law.
What if I never filed a preliminary notice — do I still have lien rights?
Possibly, but it depends on your state. In California, a late preliminary notice limits lien rights to work performed in the 20 days before service — you lose protection for earlier work. In Florida, missing the 45-day preliminary notice window is a complete bar to a mechanics lien on private projects. In some states, no preliminary notice is required for first-tier subcontractors. Know your state's rules before assuming you're protected or that you're not.
How long does a mechanics lien stay on a property title?
Lien duration varies by state. In California, a mechanics lien is valid for 90 days after recording, after which you must file a lawsuit to enforce it or the lien expires. In Florida, an uncontested lien is valid for 1 year. In Texas, you typically have 2 years from the lien recording date to file suit. If you record a lien and don't enforce it, it will eventually expire — but the GC or owner may also move to have it released sooner.
Can I file a mechanics lien and still negotiate payment at the same time?
Yes — and this is often the right strategy. Filing a lien doesn't mean you're going to court. It creates leverage. Many payment disputes settle after a lien is recorded because the owner now has a direct financial interest in resolving it. You can release the lien the moment payment clears. Never hold off on filing just because talks are ongoing — if you miss your deadline during negotiations, you lose the leverage entirely.
What does a final payment demand letter need to say to be legally effective?
At minimum: your company name, the project address, a specific dollar amount owed itemized by contract balance and retainage, the date payment was due, a response deadline (7–10 business days), and clear notice that you will file a mechanics lien and pursue legal remedies if payment is not received. Send it via USPS Certified Mail so you have proof of delivery. Some contracts require a specific form of written notice before legal action — check your subcontract.
What is the difference between a mechanics lien and a bond claim?
A mechanics lien is filed against the real property itself and is available on private construction projects. A bond claim is made against a surety payment bond and is the primary remedy on public jobs where the government owns the property and liens are not allowed. On federal projects, payment bond rights are governed by the Miller Act (40 U.S.C. § 3133). On state public jobs, "Little Miller Act" statutes apply and vary by state.
Does the GC have to pay interest on late final payment?
In many states, yes. California imposes 2% monthly interest on late payments to subcontractors on private works under Cal. Civ. Code § 8800. Texas provides 1.5% monthly interest under the Prompt Payment Act (Tex. Prop. Code § 28.004). Florida's Prompt Payment Act (Fla. Stat. § 218.735 on public jobs; § 255.073 on state contracts) also provides for interest and attorney's fees. Check your state's prompt payment statute — the interest provisions give you additional recovery beyond the base amount owed.
Can a GC make me sign a lien waiver before releasing final payment?
A GC can request a lien waiver as a condition of payment — this is standard practice. The critical rule: only sign a final lien waiver after the check clears or at the same moment you receive a certified check. Never sign a final or unconditional lien waiver in exchange for a promise of future payment. If the GC is asking you to waive lien rights before releasing money you've already earned, that's a red flag. Use a conditional lien waiver (conditioned on payment clearing) if the GC insists on paperwork before issuing the check.
Protect Your Lien Rights Before the Next Job — and This One
If a GC won't pay final payment and your preliminary notice is already on file, you have real leverage. If it's not, your options narrow fast. The single most effective thing you can do on every job — before you're ever in a payment dispute — is file a preliminary notice within the first few days of furnishing labor or materials.
LienFlash generates state-compliant, attorney-reviewed preliminary notices in about 2 minutes, sends them via USPS Certified Mail with a Certificate of Mailing PDF, and covers Florida, California, Arizona, Nevada, Washington, Oregon, Texas, and New Mexico. A single notice is $24.99. If it preserves lien rights on a $15,000 contract that would otherwise go unpaid, the math is not complicated.
Don't wait until you're chasing money. File the notice when you show up on day one.
