Tony had been in the trades for nineteen years. Roofing, mostly. He ran a tight crew out of Union County, did quality work, and had built most of his business on referrals. He was good at what he did, and he’d never had a serious problem getting paid.
Until he did.
A general contractor hired him for a commercial re-roofing job in Essex County — a sizeable project, eight weeks of work, just over $140,000. The job went well. Tony’s crew finished on schedule. The punch list got cleared. And then the invoices sat. Thirty days. Sixty days. The GC kept saying payment was coming, that the owner was slow, that it would be sorted. At ninety days, Tony started asking harder questions.
That’s when he found out the GC had already been paid by the property owner. And had used the money for other things.
Tony called an attorney. The attorney asked about the lien. Tony didn’t know what that meant. By the time he understood what a construction lien was and how it worked, the window to file one had closed. He was left chasing a GC with no assets and a property owner who felt zero obligation to pay him twice.
$140,000. Gone. Because Tony didn’t know about a law that existed specifically to protect him.
The Law That’s On Your Side — If You Know How to Use It
New Jersey’s Construction Lien Law — formally N.J.S.A. 2A:44A-1 et seq. — exists for exactly the reason Tony needed it. It’s designed to protect contractors, subcontractors, suppliers, and design professionals who perform work or provide materials for a construction project and don’t get paid.
The basic mechanism: if you’re owed money for work you did on a property, you can attach a lien to that property. The property can’t be sold, refinanced, or transferred cleanly without that lien being resolved. It gives you leverage — real, documented, legally enforceable leverage — against a property you’ve put your labor and materials into.
But here’s the thing most contractors don’t understand: the lien right isn’t automatic. You have to claim it. And you have to claim it the right way, within specific deadlines, using specific procedures. Miss the window, file incorrectly, or skip a required notice — and the right evaporates. Just like it did for Tony.
If you’re a contractor or subcontractor doing work in New Jersey and you’re not fully clear on how this law works, that’s a gap worth closing. Construction compliance review services in NJ can help you make sure you understand where you stand before you need the protection.
The Basics: Who Has Lien Rights in New Jersey?
Not everyone on a job site has lien rights. The NJ Construction Lien Law covers:
- General contractors with a direct contract with the property owner
- Subcontractors hired by a general contractor or construction manager
- Sub-subcontractors hired by subcontractors (with limitations)
- Material suppliers who furnish materials for the project
- Architects, engineers, and other design professionals
Notably, the law distinguishes between residential and commercial projects, and the requirements differ depending on which side of that line your project falls on. Residential projects — generally defined as one- to four-family homes — have specific rules about notice, timing, and the lien process that differ from commercial work.
And for subcontractors — this is critical — you’re not in a direct relationship with the property owner, which makes the lien law especially important. You’re working for a GC who may or may not pay you depending on what’s happening upstream. The lien law gives you a direct path to the property regardless of what’s happening in that middle layer.
The Key Requirements: What You Actually Have to Do
Step 1: Provide a Notice of Unpaid Balance (NUB) — For Subcontractors
If you’re a subcontractor, you’re required to give a Notice of Unpaid Balance and Right to File Lien (NUB) before you can file a lien claim. This notice goes to both the property owner and the GC, and it triggers a 10-day period during which the GC can dispute the amount you claim is owed.
This step surprises a lot of subcontractors. They think “I’ll just file the lien.” But skipping the NUB — or serving it incorrectly — can invalidate the entire lien. The notice has to be properly served, to the right parties, at the right time.
Step 2: File the Lien Claim Within the Deadline
This is where most contractors lose their rights. The filing deadline in NJ is 90 days from the last date you provided work, labor, or materials on the project.
90 days sounds like plenty of time. It’s not. Projects often have slow-burning payment disputes, and by the time a contractor accepts that payment isn’t coming voluntarily, the clock has often been ticking for weeks. By the time they call an attorney and get organized, the window is sometimes already closed.
The lien claim is filed with the county clerk in the county where the property is located. It has to include specific information — a description of the property, the amount claimed, the nature of the work, the parties involved. Missing required elements can get the lien thrown out.
Step 3: Commence a Lien Action Within One Year
Filing the lien is not the end of the process. It’s the beginning of the legal enforcement phase. Once you’ve filed, you have one year to file a lawsuit to enforce the lien. If you don’t pursue it within that window, the lien expires and the right to collect through this mechanism disappears.
Most legitimate lien claims don’t actually go to trial — the lien creates enough pressure that disputes often resolve before then. But you need to be prepared to follow through, and you need an attorney who handles construction law if you’re at this stage.
Common Mistakes That Kill Lien Rights
Missing the 90-Day Filing Window
Already mentioned this, but it deserves emphasis. The deadline runs from the last date of your work, not the completion of the overall project. If you finished your scope in month three of a six-month project, your clock started in month three. Waiting until the project is “done” to think about the lien is one of the most common errors — and one of the most expensive.
Skipping the NUB as a Subcontractor
Some subcontractors don’t know the NUB is required. Others know about it but think they can skip it and file the lien directly. You can’t. At least not validly. The NUB is a prerequisite to the lien for subcontractors, and courts take it seriously.
Filing in the Wrong County
The lien goes with the property. The property determines the county. If you file in the wrong county clerk’s office, the lien is invalid. Sounds like something anyone would catch, but when you’re managing multiple jobs in multiple counties, it’s an easy administrative error with serious consequences.
Claiming More Than You’re Owed
You can only lien for work actually performed and materials actually furnished. Inflating the claim — even accidentally — can expose you to sanctions and damages under the law. The lien amount needs to be supportable.
Not Having the Contract Documentation to Back It Up
A lien is only as good as the underlying claim. If you get to enforcement and can’t demonstrate what work was done, what it cost, and what the agreement was — verbally or in writing — the lien won’t survive. Good documentation throughout the project protects you at every stage.
Expert Perspective: What Contractors Often Don’t Know Until It’s Too Late
The lien law is powerful. But it requires you to be proactive, not reactive.
Most contractors think of lien rights as something you reach for when payment fails. That’s backwards. The right approach is to understand your lien rights before the project starts, confirm your documentation practices are solid, and know your deadline from the moment your scope of work begins.
For subcontractors especially, the relationship structure creates risk you can’t fully control. Your payment depends on a GC being paid, and on that GC choosing to pass the payment along to you. The lien law gives you a path around that dependency — but only if you’ve preserved it.
NJ construction compliance review services are worth considering not just when you have a problem, but as part of how you set up your business practices. Understanding lien rights, documentation requirements, and contract terms before you’re in a dispute is dramatically more valuable than trying to reverse-engineer protection after payment has already failed.
A few things worth building into your standard operating procedure:
- Track your last date of work on every project — not the project completion date, your last date. Your 90-day clock starts there.
- Keep contemporaneous records of all work performed, materials furnished, and communications about payment.
- Use written contracts — even on projects where a handshake feels sufficient. A written contract with clear payment terms is your foundation for any lien claim.
- Don’t wait to see if payment “comes through” — if payment is more than 45 days late, it’s time to start the lien process, not wait another 45 days.
Frequently Asked Questions
Can I file a construction lien on a residential property? Yes, but residential projects — one to four-family homes — have specific requirements that differ from commercial. Notably, for residential properties, subcontractors may need to serve a preliminary notice at the start of the project to preserve lien rights. The rules are more complex, and getting them wrong is expensive. If you’re doing residential work, get familiar with those specific requirements before a dispute arises.
What if I have a verbal agreement — no written contract — with the GC? You can still have a valid lien claim without a written contract, but proving the amount owed and the scope of work becomes much harder. Verbal agreements are also harder to enforce in court if the lien gets disputed. This is one of the strongest arguments for always getting your agreement in writing, even informally.
Does filing a lien guarantee I’ll get paid? No. The lien attaches to the property and creates legal pressure, but it doesn’t guarantee payment. If the property doesn’t sell or refinance, the pressure can be limited. And the lien has to be enforced through a court action if the dispute doesn’t resolve. It’s a powerful tool — not a magic solution.
What happens if the property owner files for bankruptcy? Construction liens can survive certain bankruptcy proceedings, but the rules are complex and depend on timing and the type of bankruptcy. If a property owner or GC files for bankruptcy while you have an active lien or pending lien rights, get legal advice immediately. The window to act can be very short.
Can I file a lien if I was a supplier but never actually set foot on the job site? Yes. Material suppliers who furnish materials for a construction project have lien rights even without physical presence at the site, as long as the materials were delivered to the project and incorporated into the work. Documentation of delivery is critical.
Back to Tony
Tony eventually collected a fraction of what he was owed — an out-of-court settlement with the GC after months of back-and-forth, for far less than the full amount. The property owner was never legally obligated to pay him a second time, and without the lien, there was nothing to force the issue.
He knows now. And his whole approach to projects has changed. Written contracts, tracked last-dates of work, NUBs as a standard practice on every subcontract, and an attorney he calls before things go sideways, not after.
“I thought the lien law was for contractors who had bigger operations than mine,” he said. “I didn’t understand it was for me.”
It is for you. But only if you use it.
If you want to make sure your business practices are set up to actually protect you — lien procedures, contract terms, documentation practices — NJ construction compliance review services are worth a conversation. Not because something has gone wrong. Because something hasn’t yet, and you’d like to keep it that way.
The law gives you the right to get paid for your work. Don’t let a deadline or a missing notice take that right away.
