Understanding Preliminary Notices in Maine

Great news for contractors in Maine: no preliminary notice is required to preserve your mechanics lien rights. If you do work on a construction project and don't get paid, you can go directly to filing a lien without any advance notice.

That said, many experienced Maine contractors still send a voluntary notice at the start of every project. Why? Because it puts your name on the property owner's radar, creates a paper trail proving you were on the job, and often speeds up payment. It costs almost nothing and can prevent payment problems before they start.

Who Needs to Send a Preliminary Notice in Maine?

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.

Why Preliminary Notices Matter

Even though Maine doesn't require a preliminary notice, sending one is smart business. It puts your name on the property owner's radar, creates a paper trail proving your involvement, and often speeds up payment. Many experienced contractors send one on every project — it's low-cost insurance against payment problems.

Who Must Receive the Lien Statement?

Who you need to notify depends on your role on the project. Here's a simple breakdown:

How to Deliver the Notice in Maine

Use one of the approved delivery methods below to make sure your notice is valid. Maine accepts these methods:

First Class Mail — Standard USPS mail. Less proof than certified mail, but some states accept it. Keep your receipt and tracking number.

Certified Mail — You send via USPS and get a green receipt card proving the notice was delivered. This is the gold standard because it creates clear proof of delivery.

Statutory Notice Language

Maine law requires your Lien Statement to include specific warning language. This isn't language you write yourself — it's exact wording specified by Me. Rev. Stat. §§ 3251 et seq.. Using the wrong language (or leaving it out) can invalidate your notice. LienGrid automatically includes the correct statutory language for Maine.

Owner Warning Language (excerpt from Me. Rev. Stat. §§ 3251 et seq.)

NOTICE: The undersigned claims a mechanics lien against your property for labor, services, or materials furnished pursuant to Maine Revised Statutes Title 10, § 3251 et seq.

Maine Preliminary Notice FAQ

Common questions about preliminary notices in Maine, 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 Maine, this document is officially called the "Lien Statement" and is governed by Me. Rev. Stat. §§ 3251 et seq..
No, Maine does not legally require a preliminary notice. You can file a mechanics lien without having sent one first. However, smart contractors and suppliers often send one anyway because (1) it creates a written record of your involvement, (2) it often speeds up payment since owners pay more attention when they know you could file a lien, and (3) it shows professionalism.
Maine doesn't have a preliminary notice deadline because no notice is required. Your key deadline to watch is the lien filing deadline: 90 days from last labor or materials provided.
In Maine, it's officially called the "Lien Statement" (formal document title: "MECHANICS LIEN STATEMENT"). 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 Maine version follows the requirements laid out in Me. Rev. Stat. §§ 3251 et seq..
It depends on your role on the project. Here's a simple breakdown: General contractors typically don't need to send a preliminary notice (since they're already in a direct contract with the owner). Subcontractors (hired by the GC or another sub) must notify: the property owner. Material Suppliers must notify: the property owner. 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. 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.
Maine accepts these delivery methods: First Class Mail, Certified Mail. 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 — Maine requires the Lien Statement to include specific warning language spelled out in Me. Rev. Stat. §§ 3251 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 Maine so you don't have to worry about getting it wrong.
Since Maine doesn't require a preliminary notice, skipping it won't affect your lien rights. You can still file a mechanics lien within 90 days if you're not paid. That said, the industry best practice is to send one anyway on every project — it's a low-cost step that often prevents payment problems from happening in the first place.
Maine's Lien Statement 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 Me. Rev. Stat. §§ 3251 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.
