Understanding Preliminary Notices in New Jersey

New Jersey uses an intent-to-lien system, which works differently from a preliminary notice. You don't need to send anything at the beginning of a project. Instead, if you haven't been paid and you're planning to file a mechanics lien, you first send a “Notice of Unpaid Balance and Right to File Lien”.

Think of it as a formal demand letter that says: “I haven't been paid for my work, and if you don't resolve this, I'm going to file a lien on your property.” It gives the property owner one final opportunity to pay before you take legal action. Many payment disputes are actually resolved at this stage — the notice itself is often enough motivation for owners to pay up.

Who Needs to Send a Preliminary Notice in New Jersey?

This applies to nearly everyone who works on a construction project and wants to protect their payment rights. That includes general contractors, subcontractors (electricians, plumbers, roofers, etc.), material suppliers (lumber, concrete, fixtures), equipment rental companies, laborers, architects and engineers, and surveyors. The specific rules — like who you need to notify and your deadline — depend on your role. Check the table below to see exactly what applies to you.

New Jersey Preliminary Notice FAQ

Common questions about preliminary notices in New Jersey, answered so anyone can understand.

A preliminary notice is a simple document you send near the beginning of a construction project to let the property owner (and sometimes the general contractor and lender) know that you're working on their property. It's NOT a threat, a lien, or a sign that something is wrong — it's a standard business practice required by law in many states. Think of it as "checking in" to say: "I'm providing labor/materials on this project, and I expect to be paid." In New Jersey, this document is officially called the "Notice of Unpaid Balance and Right to File Lien" and is governed by NJ Stat. Ann. §§ 2A:44A-1 et seq..
Yes, New Jersey requires it. If you skip this step, you could lose your right to file a mechanics lien later — which means you'd have much less legal leverage if you don't get paid. In New Jersey, you send the "Notice of Unpaid Balance and Right to File Lien" before filing a mechanics lien, as a final demand for payment. The notice requirement exists to ensure transparency on construction projects — everyone involved should know who is providing labor and materials.
You have 60 days from the date you FIRST provide labor or materials to the project. Your "clock starts" on your very first day of work or your first delivery. For example, if you delivered lumber on March 1st, you'd need to send the Notice of Unpaid Balance and Right to File Lien by 60 days later. Pro tip: send the notice as soon as you start a project — don't wait until the deadline is close.
In New Jersey, it's officially called the "Notice of Unpaid Balance and Right to File Lien" (formal document title: "NOTICE OF UNPAID BALANCE AND RIGHT TO FILE LIEN"). Different states use different names for essentially the same concept — you might hear it called a "preliminary notice," "notice to owner," "notice of furnishing," or "pre-lien notice" depending on the state. The New Jersey version follows the requirements laid out in NJ Stat. Ann. §§ 2A:44A-1 et seq..
It depends on your role on the project. Here's a simple breakdown: General Contractors (hired directly by the owner) must notify: the property owner. Subcontractors (hired by the GC or another sub) must notify: the property owner. Material Suppliers must notify: the property owner, the general contractor, subcontractor. Laborers follow the same rules as subcontractors and must notify: the property owner. Equipment rental companies follow material supplier rules and must notify: the property owner, the general contractor, subcontractor. Design professionals (architects, engineers, surveyors) must notify: the property owner. It's critical to send the notice to ALL required parties — missing even one can weaken your legal standing.
New Jersey accepts these delivery methods: Certified Mail, Personal Delivery. Most people use certified mail because it gives you a receipt proving the notice was sent AND received — this is your proof if there's ever a dispute. Keep the receipt and tracking number in your project file. Important: if you use a delivery method that isn't on the approved list, your notice could be considered legally invalid even if the recipient actually received it. Don't take shortcuts with delivery.
Yes — New Jersey requires the Notice of Unpaid Balance and Right to File Lien to include specific warning language spelled out in NJ Stat. Ann. §§ 2A:44A-1 et seq.. This isn't language you make up yourself. The state has exact wording that must appear on the notice, explaining to the property owner their rights and the potential consequences of unpaid work. Using the wrong language (or leaving it out) could make your notice invalid. This is one reason many contractors use tools like LienGrid — it automatically includes the correct statutory language for New Jersey so you don't have to worry about getting it wrong.
This is a big deal: if you skip the required Notice of Unpaid Balance and Right to File Lien in New Jersey, you could completely lose your right to file a mechanics lien. That means if you're not paid for $50,000 worth of work, you might have no lien to fall back on. You could still pursue other legal options like breach of contract lawsuits, but those are more expensive and time-consuming than filing a lien. The preliminary notice is your insurance policy — a small upfront step that protects potentially large payments down the road. Never skip it.
New Jersey's Notice of Unpaid Balance and Right to File Lien requirements apply to both types of projects, but there can be important differences. Residential projects (homes, condos, small apartments) often have extra protections for homeowners — for example, some states require additional disclosures or have shorter deadlines for residential work. Commercial projects (offices, retail spaces, industrial buildings) may have different thresholds or requirements. Always check NJ Stat. Ann. §§ 2A:44A-1 et seq. for the specific rules that apply to your project type, or use a compliance tool like LienGrid that automatically adjusts for the project type.
