If your general contractor pockets your payments and leaves the subcontractors unpaid, the laws that protect property owners when a general contractor doesn’t pay subcontractors are a mix of payment bond statutes, lien waiver rules, construction trust fund laws, retainage caps, and contract tools like indemnification and joint check agreements. None of them stop a dishonest contractor on their own. Together, and built into the project from the start, they keep unpaid subcontractors from turning your house or building into collateral for someone else’s debt.
The Risk You’re Actually Protecting Against
Every state has a mechanic’s lien law, and the rule is the same everywhere: anyone who supplies labor or materials to improve your property can file a legal claim against the property itself if they don’t get paid. It doesn’t matter that you already paid the general contractor in full. The lien attaches to your real estate, not to the person who stiffed the sub.
A lien clouds your title. You generally cannot sell or refinance until it’s resolved, whether by paying it off, negotiating a release, or litigating it. In the worst case, a lien can be foreclosed and you can lose the property, though most disputes settle long before that.
Subcontractors must follow strict procedural rules to file a valid lien, and those rules give owners some built-in warning. Most states require subs to serve a preliminary notice on the owner early in the project, often within 20 to 60 days of first providing labor or materials. Skip the notice and the sub can lose the right to lien entirely. Treat those notices as useful intelligence: they tell you exactly who is on your project and who could file against your property.
Filing deadlines vary, but subcontractors in most states must record the lien within roughly 60 to 120 days after they last worked. Some states let you shorten that window by recording a notice of completion once the job wraps, cutting the filing period to as few as 30 days.
Payment Bonds Are the Strongest Shield
A payment bond is the single most effective protection against subcontractor liens. The bond is issued by a surety company and guarantees that if the general contractor fails to pay subcontractors or suppliers, the surety will. Unpaid subs chase the bond instead of your property.
On federal construction projects, payment bonds are mandatory. The Miller Act requires any contractor working on a federal building or public works project worth more than $100,000 to post a payment bond before the contract is awarded.1Office of the Law Revision Counsel. 40 U.S. Code 3131 – Bonds of Contractors of Public Buildings or Works Public property cannot be subjected to mechanic’s liens in the first place, so the bond acts as the substitute remedy for unpaid subs. Any Miller Act claim by a sub must be filed no later than one year after that claimant last furnished labor or materials.2Office of the Law Revision Counsel. 40 U.S. Code 3133 – Rights of Persons Furnishing Labor or Material
For state and local public works, every state has adopted its own version, commonly called a “Little Miller Act,” requiring payment bonds on publicly funded construction. Thresholds vary widely, from as low as $25,000 in some states to $100,000 or more in others.
On private projects, no law forces a payment bond. You have to require one in your contract with the general contractor. The premium typically runs 1% to 3% of the contract price. For a custom home or a major renovation, requiring the GC to post a payment bond is one of the most effective moves an owner can make.
Lien Waivers at Every Payment
Lien waivers are the day-to-day paperwork that keeps claims from stacking up. A lien waiver is a document signed by a subcontractor or supplier giving up the right to file a lien, usually in exchange for payment. You pay, they sign away the lien right for that payment, and your title stays clear.
There are two variables that define the four standard forms: whether the waiver covers a progress payment or the final payment, and whether it’s conditional or unconditional. Conditional waivers only take effect once the payment actually clears, so if the check bounces, the lien right survives. Unconditional waivers take effect the moment they are signed, regardless of whether the money has been received. During the project, conditional waivers are the safer choice for everyone because nobody’s rights are stripped until the money actually changes hands. Many states have statutory forms, and using a non-compliant form can make the waiver unenforceable.
Build lien waiver collection into the contract as a condition of each progress payment. Before releasing any funds, collect signed waivers from the general contractor and from every subcontractor and supplier who worked during that billing cycle.
One underappreciated risk: a general contractor handing you a lien waiver the subcontractor never actually signed. Some states treat forged waivers as a felony, but the criminal statute does not help if liens are already recorded against your property. The practical safeguard is to verify waivers directly with the subcontractors themselves, especially on larger payments.
Construction Trust Fund Statutes
About 19 states have enacted construction trust fund statutes. Under these laws, money the owner pays to the general contractor is treated as held in trust for the subcontractors and suppliers who earned it. The contractor is the trustee. Using those funds for anything else can be charged as theft.
Penalties vary by state and by the dollar amount diverted, ranging from misdemeanor fines to felony charges carrying prison time. Some states also let injured parties recover treble damages (three times the actual loss) plus attorney’s fees in civil court.
These statutes don’t physically stop a dishonest contractor, but they change the leverage. A contractor who diverts your construction funds is not just breaching a contract; in trust fund states, they are committing a crime. That threat often motivates fast resolution of payment disputes that would otherwise drag on.
Retainage
Retainage is the practice of withholding a percentage of each progress payment until the project is substantially complete. It gives you a financial cushion for defects, punch-list items, and unpaid subcontractor claims. Most states cap retainage somewhere between 5% and 10% of the contract value, with the recent trend toward 5%. At least one state prohibits retainage entirely on most projects.
Timing matters as much as the amount. State laws typically require the owner to release retainage within a set period after substantial completion or issuance of a certificate of occupancy. Many states also require the general contractor to pass retainage through to subcontractors within a specified number of days after receiving it, so the money actually reaches the people who earned it.
Withhold the maximum retainage your state allows. If you discover subs haven’t been paid, that reserve gives you leverage to demand proof of payment before you release the final check.
Direct Payments and Joint Check Agreements
When the normal payment chain breaks down, two contract mechanisms let you get money straight to the subcontractors doing the work.
A direct payment clause in your agreement with the GC lets you pay subcontractors or suppliers directly in defined circumstances, typically when the general contractor defaults or when there is clear evidence subs aren’t being paid. The pitfall is double payment: if you pay a sub directly and the GC later claims that payment was already covered inside the contract price, you can end up paying twice. The risk gets worse if the general contractor becomes insolvent, because a bankruptcy trustee may argue that direct payments to subs were not proper deductions from the contract balance. Never make a direct payment without a written acknowledgment from the GC (or a court order) and a lien waiver from the sub for the amount paid.
A joint check agreement is simpler. Instead of bypassing the GC, you issue a check made payable to both the general contractor and the subcontractor. Both must endorse it before deposit, which guarantees the subcontractor sees the money. In exchange, the subcontractor provides a lien waiver for the amount of the check. Joint check arrangements are not regulated by statute, so terms are entirely negotiable. They work best when they are built into the contract at the start rather than improvised after trouble appears.
Indemnification Clauses
An indemnification clause in your contract with the general contractor shifts liability for subcontractor payment claims (along with other risks) from you to the contractor. If a sub files a lien or a lawsuit because the GC didn’t pay, the clause obligates the contractor to defend the claim and cover your losses.
These clauses have real limits. Roughly 45 states have anti-indemnity statutes that restrict or prohibit “broad form” indemnification in construction contracts, meaning clauses that would make the contractor indemnify you even for your own negligence. The pattern varies by state, but a contractor can generally be required to indemnify you for the contractor’s own failures, such as not paying subs, but not for problems you caused. A clause drafted too broadly can be struck down entirely rather than just narrowed.
There’s a practical limit too. An indemnification clause is only as good as the contractor’s ability to pay. If the GC is judgment-proof or in bankruptcy, the clause is worthless. That is why experienced owners pair indemnification requirements with insurance mandates and payment bonds; the bond and the policy give the promise real financial backing.
What to Do Before and During the Project
None of these protections activate automatically. They have to be built into the project structure from day one.
- Require the general contractor to post a payment bond on any project large enough to justify the premium. For most owners, this is the single most valuable step.
- Make lien waivers a condition of every progress payment. Collect signed waivers from the GC and from every subcontractor and supplier who worked during that billing period. Use conditional waivers until the payment clears, then swap for unconditional ones.
- Keep a running list of everyone who sends a preliminary notice. Those are the parties with potential lien rights against your property. Cross-reference the list against the waivers you receive.
- Verify payments directly with subcontractors on larger billings. A GC who resists that kind of transparency is a warning sign.
- Record a notice of completion promptly if your state allows it. The filing can sharply shorten the window for lien claims, in some states down to 30 days.
- Withhold the maximum retainage your state permits. Don’t release it until you have proof of payment from the subcontractors themselves, not just a waiver signed by the GC on their behalf.
Most owners first hear about any of this after a lien is already recorded and a lawyer is already involved. By then, the tools above are harder to use and more expensive to deploy. Put them in the contract and run them through every payment cycle, and the scenario that brought you to this page becomes much harder for a contractor to create.
