Understanding Maine Mechanics Lien Law

If you've done construction work in Maine and haven't been paid, you have the legal right to file a mechanics lien under Me. Rev. Stat. §§ 3251 et seq.. A mechanics lien is a claim against the property you improved — it prevents the owner from selling or refinancing until your payment is resolved.

Good news: Maine does not require any preliminary notice before filing a mechanics lien. If you're not paid for work done in Maine, you can go directly to filing a lien. However, you must still meet the 90 days filing deadline, so don't wait too long.

Who Can File a Mechanics Lien in Maine?

Nearly anyone who contributes to a construction project can file a lien if they're not paid. This includes general contractors, subcontractors (electricians, plumbers, roofers, etc.), material suppliers (lumber, concrete, fixtures), equipment rental companies, laborers, architects and engineers, and surveyors. You don't need a direct contract with the property owner — even if you're several layers down the payment chain, Maine law likely protects your right to get paid. The specific rules (like notice deadlines) vary by your role, so check the details below.

How a Mechanics Lien Protects You

A mechanics lien is one of the most powerful payment tools in construction — it puts a legal claim on the property itself. That means the owner can't easily sell, refinance, or get a clear title until your payment is resolved. In many cases, filing a lien typically motivates payment without going to court. To protect your lien rights, file on time and follow Maine's notice requirements. That's what this guide covers.

Maine Preliminary Notice Requirements

No Preliminary Notice Required

Maine does not require you to send a preliminary notice before filing a lien. However, sending a voluntary notice is still recommended as a best practice — it creates documentation and often motivates faster payment.

Maine Mechanics Lien FAQ

Common questions about mechanics liens in Maine, answered in plain English.

In plain English: a mechanics lien is your legal right to get paid for construction work. If you did work on a building or property in Maine and the person who owes you money won't pay, you can place a lien — essentially a legal "hold" — on that property. This means the property owner can't easily sell or refinance until your bill is settled. If they still refuse to pay, you can go to court to force the sale of the property to collect what you're owed. In Maine, this protection comes from Me. Rev. Stat. §§ 3251 et seq.. It exists because construction is unique — you can't exactly repossess the plumbing you installed or the foundation you poured. Nearly anyone who works on a project (contractors, subs, suppliers, laborers, architects, engineers) can use this protection.
No. Maine does not require you to send any advance notice before filing a mechanics lien. You can go directly to filing a lien if you're not paid. However, many experienced contractors still send a voluntary notice because it creates a paper trail and often motivates faster payment — when property owners learn you're on the project, they pay closer attention to making sure everyone gets paid.
You have 90 days from last labor or materials provided to file your mechanics lien with the county recorder's office. This is a hard deadline — if you miss it, you lose your right to file a lien on that project entirely. For example, if you finish work on a project in March and the deadline is 90 days, start counting from your last day of work (or last material delivery) and make sure your lien is filed and recorded before that window closes. Pro tip: mark this date on your calendar the day you start a project and set reminders well in advance.
Under Me. Rev. Stat. §§ 3251 et seq., the following people and companies can file a mechanics lien in Maine if they're not paid for work on a construction project: general contractors (the main company hired by the property owner), subcontractors (plumbers, electricians, roofers, HVAC techs, etc. hired by the GC), sub-subcontractors (companies hired by subs), material suppliers (lumber yards, concrete companies, fixture suppliers), equipment rental companies (cranes, excavators, scaffolding), laborers and workers, architects and engineers who design the project, and surveyors. The key thing to understand: you don't need a direct contract with the property owner to file a lien. Even if you're three layers down the payment chain (the owner hired a GC, who hired a sub, who hired you), you likely still have lien rights in Maine. However, the specific notice requirements and deadlines vary depending on your role — subcontractors and suppliers typically have extra steps that general contractors don't.
Maine requires you to use one of these approved delivery methods: First Class Mail, Certified Mail. Certified mail is the most commonly used method because it provides a receipt proving the notice was sent and delivered — this proof is important if there's ever a dispute. Using the wrong delivery method can make your notice legally invalid, so always stick to the approved methods. Keep copies of all delivery receipts and tracking information.
Who you need to notify depends on your role on the project. If you're the general contractor, you typically don't need to send a preliminary notice. If you're a subcontractor (hired by the GC or another sub), you need to notify: the property owner. Material suppliers must notify: the property owner. Laborers typically 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. Missing even one required recipient can weaken or invalidate your lien rights.
After you file a mechanics lien, it doesn't automatically get you paid — it's just a legal claim against the property. To actually collect, you need to "enforce" the lien by filing a lawsuit (called a foreclosure action) in court. In Maine, you must file this lawsuit within 120 days after recording the lien. If you don't file suit in time, the lien expires and you lose that leverage. The good news is that most liens get resolved through payment or negotiation before going to court — the lien itself is often enough motivation for the property owner to pay.
Yes, Maine mechanics lien laws cover both residential projects (homes, apartments, condos) and commercial projects (offices, retail spaces, warehouses). However, the rules can differ between the two. Residential projects often have extra protections for homeowners, while commercial projects may have different deadlines or notice requirements. Always check whether your specific project has any special rules under Me. Rev. Stat. §§ 3251 et seq..

Here's the process step by step, with why each step matters:

Step 1 — Confirm no preliminary notice is required for your situation (in some states it is, but not always in Maine). WHY: Sending a voluntary notice is still smart — it puts your name on the owner's radar and often speeds up payment.

Step 2 — Document everything: keep records of your contract, invoices, delivery tickets, and communications about nonpayment. WHY: If this goes to court, your records are your evidence.

Step 3 — Prepare your lien claim with your name, the property address, description of work performed, dates of first and last work, and the exact amount owed. WHY: Errors in the lien document can get the whole thing thrown out.

Step 4 — File the lien claim at the county recorder's office (small recording fee, usually $10-$75) within the 90 days deadline. WHY: This is the legal moment your claim attaches to the property — miss the deadline and you lose the right entirely.

Step 5 — Send a copy of the filed lien to the property owner. WHY: Many disputes resolve right here — owners take liens very seriously because they cloud the property title and block sales and refinancing.

Step 6 — If still not paid, file a lawsuit (foreclosure action) within 120 days. WHY: The lien expires if you don't enforce it. But most cases settle before this stage.

Great news: Maine doesn't require any advance notice to file a mechanics lien. If you're not paid for work on a construction project, you can go straight to filing a lien within the 90 days deadline. That said, many experienced contractors still send a voluntary notice at the start of a project — it's good business practice and often leads to faster payment.
Maine has some important rules that can trip people up: (1) Prime contractors with direct contract need not file lien statement in registry. (2) Subs without contract with owner must record within 90 days. (3) Must provide copy to owner via US mail after filing. (4) Certificate from clerk or affidavit must be recorded within 60 days of complaint. These details matter — overlooking any of them could affect your ability to get paid. When in doubt, consult Me. Rev. Stat. §§ 3251 et seq. or speak with a construction attorney in Maine.
