New York Lien Law Article 3-A Trust Fund Claims: A Guide for NYC Contractors, Subs, and Owners

You wired a $400,000 progress payment to your general contractor for the gut renovation of your Upper West Side condo. Two weeks later, three subcontractors file mechanic's liens against your unit. They say they haven't been paid. The GC won't return your calls — and you're learning, painfully, that money you thought went to your project may have gone somewhere else entirely.

That's exactly the problem New York's Lien Law Article 3-A trust fund regime was designed to solve. The statute treats every dollar paid for a private improvement as money held in trust for the people doing the work below the recipient. When a contractor or sub takes those funds and uses them for unrelated expenses, that's a "trust fund diversion" — and it can mean civil liability, personal liability for company officers, and a felony charge. If you're a NYC homeowner, a developer, a general contractor, or a sub trying to get paid on a project gone sideways, the Lien Law Article 3-A trust fund rules are some of the sharpest tools in New York construction law. At Yassi Law, we use them on both sides of the table — for owners chasing diverted deposits and for subs trying to collect on six- and seven-figure unpaid invoices.

What is a Lien Law Article 3-A trust fund and why does it matter on NYC projects?

A Lien Law Article 3-A trust fund is a statutory trust that automatically attaches to money received by a contractor, subcontractor, or owner for an improvement to real property in New York. There's no trust document to draft and no formal step to take. Under Lien Law § 70, the funds become trust assets the moment they're paid, advanced, or earned for work on the project.

The practical consequence is enormous. Money sitting in a contractor's operating account that came from your Tribeca buildout isn't just "the contractor's money" subject to its discretion. It's earmarked, by law, for the laborers, suppliers, and subs whose work generated that payment in the first place. Pulling that money out to cover payroll on a different job, a tax bill, or the owner's car lease is a diversion — even if the diverter intends to repay it later.

Why does that matter on a New York City job? Because NYC construction runs on a long chain of cash flow. The U.S. Census Bureau's Construction Spending data consistently shows New York among the top states for private nonresidential construction spending, and a single Manhattan high-rise renovation can layer five tiers of contractors and suppliers. When the GC at the top of that chain misuses funds, every tier below it gets squeezed. Article 3-A is what gives the lower tiers a remedy that doesn't depend on the GC's solvency or willingness to negotiate.

For homeowner-owners, there's an even more specific protection. Lien Law § 71-a requires that money advanced under a residential home improvement contract — the type of contract regulated by GBL Article 36-A and overseen by the NYC Department of Consumer and Worker Protection — be either deposited into a trust account or covered by a bond or contract of indemnity before the contractor can use it. If your Park Slope contractor took your $50,000 deposit and immediately moved it to its operating account without complying with § 71-a, you may already have a trust fund claim before the first nail is driven.

Who are the beneficiaries of a Lien Law Article 3-A trust fund?

The beneficiaries are anyone with a legitimate claim arising from work or materials on the project. Lien Law § 71 defines both the trust assets and the permitted uses. Trust assets include funds received from the owner, loan advances, insurance proceeds tied to the project, and rights of action arising out of the project. Permitted uses are limited to paying subs, materialmen, architects, engineers, surveyors, laborers, taxes and union benefits owed for project labor, and certain premiums for insurance and bonds.

Anything outside that list is a diversion. That's the rule subs and suppliers should commit to memory: if the GC paid its rent, paid down a credit line, or funded payroll on a different job using your project's money, those are not permitted uses. The Court of Appeals has policed that line for decades. It is well established that funds received by a contractor for a private improvement are impressed with a trust the moment they're received, and a third party that helps misapply them — including a lender — can be on the hook.

The hierarchy of beneficiaries is also important. A subcontractor is a beneficiary of the GC's trust. A sub-sub or supplier is a beneficiary of the subcontractor's trust. The owner of a private improvement is a beneficiary, too, of any trust held by its GC, because under § 71 the owner's payments must be applied to the project before the GC takes profit. That's why owners — not just subs — can sue when funds are diverted.

Most subcontractors miss that they don't have to file a mechanic's lien to be a trust fund beneficiary. The two remedies are independent. A sub that blew the four-month lien deadline under Lien Law § 10 on a private commercial job can still be a fully eligible Article 3-A beneficiary chasing diverted funds.

When does diverting trust funds become a felony?

Trust fund diversion crosses into criminal territory under Lien Law § 79-a, which classifies the misapplication of trust funds as larceny. The statute is unusual: it specifically defines diversion as a form of theft and sets felony thresholds. If the diverted amount exceeds $1,000, the conduct can be prosecuted as a felony grade matching the corresponding tier under the Penal Law's larceny statutes — meaning serious diversions on a $5 million renovation can be charged as Class C or Class B felonies.

That criminal exposure runs to officers, directors, and managing agents personally. The statute reaches "any person who has any interest as beneficiary of such trust" and any officer, director, or agent of a corporate trustee who knowingly participates in the diversion. So the owner of a contracting LLC who signs the check moving project money to a personal credit card is not insulated by the LLC's corporate veil. Article 3-A pierces straight through it.

Civil exposure is broader still. A trust beneficiary can sue the corporate trustee, the diverting officers personally, and any third party that received trust assets with knowledge of the diversion. New York courts have held that knowledge can be inferred from circumstances — a bank or affiliate that swept project funds to satisfy unrelated debts can find itself a defendant for its role in receiving allegedly diverted trust funds.

For NYC owners, this matters because it changes settlement leverage. A contractor staring at a civil trust diversion claim plus a § 79-a referral to the Manhattan DA's construction fraud task force is a contractor far more inclined to return diverted deposits than fight. Experienced commercial litigators watch for the moment when the criminal exposure becomes credible and use it to drive resolution without ever filing a complaint with the prosecutor.

How do you actually enforce a Lien Law Article 3-A trust fund claim in court?

You enforce it by filing a representative action under Lien Law § 77. That's the procedural vehicle: a beneficiary sues on behalf of all similarly situated beneficiaries, much like a class action but with its own statutory framework. The case can be brought in New York Supreme Court, and complex matters are eligible for assignment to the Commercial Division.

The complaint typically pleads several causes of action together. The core claim is breach of the Article 3-A trust. Add a claim against individual officers for knowing participation in diversion. Add an alter-ego or veil-piercing count if the corporate trustee is a shell — you can read more about how New York courts approach that analysis in our piece on when New York courts pierce the corporate veil. If a third-party recipient like a bank or affiliate took trust funds with knowledge, plead a claim against them too.

Timing matters. A § 77 action must be brought no later than one year after completion of the improvement and either three months after the project's final payment becomes due or one year after the date the trust assets were received, whichever later. Read the statute carefully — the deadlines are project-specific. Missing the § 77 window does not always extinguish all remedies, but it can knock out the most powerful one.

Provisional relief is often the difference between collection and a paper judgment. New York courts will issue prejudgment attachments under CPLR § 6201 and accountings to freeze and trace project funds when there's a credible showing of diversion. We routinely pair the § 77 trust claim with motions for an accounting and an order directing the contractor to produce records under Lien Law § 76, which gives any beneficiary the statutory right to examine trust books on demand. If you've been through a payment fight before, the strategic playbook overlaps with the broader business-litigation issues covered in our guide to NY business litigation services and our overview of common commercial litigation cases.

Recovery can also include the contract balance, project-related damages, and — if you can prove them with reasonable certainty — consequential losses like delay damages on a stalled NYC build. For more on damages methodology, see our explainer on lost profits damages in New York breach of contract cases.

What books and records does Article 3-A require — and what happens if a contractor can't produce them?

Article 3-A imposes specific bookkeeping duties under Lien Law § 75. Every trustee — every contractor, sub, and owner-developer that receives trust funds — must keep books or records showing trust assets received, trust accounts payable, transfers to other trust accounts, and trust payments made. The records must distinguish trust funds from non-trust funds and must be available for inspection by beneficiaries.

Here is the leverage point most contractors don't appreciate: failure to keep these records carries a statutory consequence. Under § 75(4), the failure to keep proper books or records is presumptive evidence that the trustee has used trust funds for non-trust purposes. In plain English, the contractor who can't produce a clean ledger has just handed the plaintiff a presumption of diversion. Combine that with § 76's right of inspection, and a sub or owner with a real claim can quickly turn an information disadvantage into a litigation advantage.

This presumption-flipping mechanism interacts powerfully with two other statutes worth knowing. The Prompt Payment Act in GBL Article 35-E sets timing rules for payment between owners, contractors, and subs on private construction contracts of $150,000 or more, with interest running on late payments. And on residential jobs, GBL Article 36-A's contract-form requirements — explained in detail in our 2026 guide to New York home improvement contract disputes — interact with § 71-a to give NYC homeowners overlapping protections on deposits.

NYC adds licensing teeth. The DCWP home improvement contractor licensing program requires anyone doing residential improvements in the five boroughs to hold an active license, and DCWP regularly publishes enforcement actions and license suspensions. An unlicensed contractor not only loses the ability to sue on its contract under New York case law — it usually faces a much harder time defending a trust fund claim, because the licensing violations corroborate the broader pattern of noncompliance. For projects that got tangled up in liability questions when injuries occurred on site, see our discussion of construction liability lessons from the Ichapanta case.

If you're a sub on a Brooklyn or Long Island City job who's been stiffed and the GC's books look sloppy, ask for them. If you're an owner who paid a deposit and the contractor can't show you a trust account or a § 71-a-compliant alternative, that's not a paperwork problem — that's evidence of a Lien Law Article 3-A trust fund violation, and it's actionable.

Frequently Asked Questions

Does Article 3-A apply only to private construction projects?

Article 3-A applies to both private and public improvement projects, but the trust assets and beneficiary structure differ slightly. On public jobs, the trust attaches to funds received under the public contract, and the beneficiaries include the laborers, subs, and suppliers who furnished work for that project. The bookkeeping and § 77 enforcement principles run in parallel.

Can I sue the contractor's owner personally for trust fund diversion?

Yes, if the owner participated in the diversion. Lien Law Article 3-A reaches officers, directors, and managing agents of corporate trustees who knowingly join in misapplying trust funds, which is why the LLC's limited liability shield does not protect a person who personally diverts project money. Pairing that personal claim with a veil-piercing theory is a common and effective strategy when the corporate trustee is undercapitalized.

How is a trust fund claim different from filing a mechanic's lien?

A mechanic's lien encumbers real property to secure payment for labor or materials, with strict timing rules under the Lien Law. A trust fund claim under Article 3-A is a personal claim against the recipient of project funds — and against officers and complicit third parties — for misapplying trust assets. You can pursue both at the same time, and a trust fund claim survives even when the lien deadline has passed.

What if my contractor went bankrupt before I could sue?

Trust fund claims often survive bankruptcy because trust assets are not property of the contractor's bankruptcy estate to begin with. Federal courts treating Article 3-A funds as held in true statutory trust generally allow beneficiaries to trace and recover those funds outside of the bankruptcy distribution. That makes Article 3-A one of the few construction remedies with real value when the contractor is insolvent — but it requires fast, well-documented action.

The Bottom Line

The Lien Law Article 3-A trust fund regime is one of the most underused weapons in New York construction litigation. For owners, it converts a stolen deposit into a personal claim against the people who took it. For subs and suppliers, it provides a recovery mechanism that survives missed lien deadlines and shaky corporate defendants alike. Whichever side of the dispute you're on, the contractor's books — or lack of them — usually tell the story.
