What a Mechanics Lien Is and How It Attaches to Property

A mechanics lien is a legal claim against a property that a contractor, subcontractor, or supplier can file when they are not paid for work or materials they provided. In New York, the lien attaches to the real property itself—not to the owner personally—which means the property cannot be sold or refinanced without addressing the unpaid debt. The lien creates a security interest that ranks ahead of many other claims, though not ahead of mortgages that existed before the lien was filed.

The mechanics lien exists because construction projects involve multiple parties working on the same property, and payment often flows down a chain. A general contractor may be paid by the property owner, but the subcontractors and suppliers who actually did the work or delivered materials may never see that money. New York law allows these parties to file a lien to force payment or force a sale of the property to satisfy the debt.

The lien is not automatic. The contractor or supplier must follow specific steps, file documents in the correct county, and meet strict important date. If these steps are missed, the right to file a lien is lost forever.

Key Takeaways

  • A mechanics lien in New York attaches to the property itself and prevents sale or refinancing until the debt is paid or resolved.
  • Contractors, subcontractors, and suppliers can file a lien, but only if they follow New York's filing rules and meet strict important date that vary by who hired them.
  • A notice of lien must be filed in the county clerk's office where the property is located within 90 days of the last work or material delivery for most parties, or within 120 days if you were hired directly by the owner.
  • Before filing a lien, most parties must first serve a notice of non-payment on the property owner and general contractor, and failure to do so can result in losing the right to file.
  • Once a lien is filed, the property owner or contractor can force a court sale to pay off the debt, so liens are taken seriously and often lead to settlement.

Who Can File a Mechanics Lien in New York

New York law allows several categories of people to file a mechanics lien. A general contractor hired directly by the property owner can file. A subcontractor hired by the general contractor can file. A supplier who delivered materials to the job site can file. A laborer who worked on the project can file. Even a design professional such as an architect or engineer can file in some cases, though the rules are stricter for them.

The key requirement is that the person or company must have a direct contractual relationship with someone in the payment chain. You cannot file a lien straightforward because you did work on a property; you must have been hired by the owner, the general contractor, a subcontractor, or another party with authority to hire you. If you were hired by someone with no authority to bind the property owner, your lien rights may be weaker or nonexistent.

Laborers have the strongest protections under New York law. A laborer can file a lien even if they were not paid by their direct employer, as long as they worked on the property. This is because laborers are considered the most vulnerable party in the payment chain.

The Notice of Non-Payment Requirement

Before filing a lien, most parties in New York must first serve a notice of non-payment on the property owner and the general contractor. This notice must be served before or within a short time after work begins, and it must state that you have not been paid and that you intend to file a lien if payment is not made.

The timing and content of this notice are strict. For a subcontractor or supplier, the notice must be served before you start work or within ten days after you start work. The notice must include your name, the name of the person who hired you, a description of the work or materials you will provide, and a statement that you will file a lien if you are not paid. The notice must be served on the property owner and the general contractor by personal delivery, certified mail, or email if the recipient has agreed to receive notices by email.

If you fail to serve this notice, you lose the right to file a lien. This is one of the most common reasons mechanics liens fail. A contractor or supplier who skips this step and later tries to file a lien will find that the lien can be discharged (removed) because the notice was not served.

A general contractor hired directly by the owner does not need to serve a notice of non-payment, because the owner already knows who hired them and what work they are doing.

Filing important date and the Notice of Lien

After work is complete or materials are delivered, you have a limited time to file a notice of lien in the county clerk's office where the property is located. The important date depends on who hired you.

If you were hired by the property owner directly, you have 120 days from the date you last performed work or delivered materials to file the notice of lien. If you were hired by the general contractor, a subcontractor, or anyone other than the owner, you have 90 days from the date you last performed work or delivered materials. These important date are strict, and filing even one day late means you lose the right to file a lien.

The notice of lien must be filed in the county clerk's office in the county where the property is located. For a property in New York County (Manhattan), you file in the New York County Clerk's office. For a property in Kings County (Brooklyn), you file in the Kings County Clerk's office. The notice must include the property owner's name, a description of the property, the amount of the lien, the name of the person who hired you, and a description of the work or materials provided.

Filing is not free. The county clerk charges a filing fee, which varies by county but is typically between $50 and $100. You must also record the notice, which means the clerk will stamp it, assign it a document number, and enter it into the public record.

What Happens After a Lien Is Filed

Once a notice of lien is filed and recorded, it becomes a public record and appears on the property's title. The property owner will learn about it when they try to refinance, sell, or obtain a title insurance commitment. The lien creates a cloud on the title that prevents these transactions from closing.

The property owner or general contractor can respond in several ways. They can pay the lien amount in full. They can dispute the lien by filing a motion in court to discharge it, arguing that the notice of non-payment was not served, the lien was filed late, the amount is wrong, or the work was not performed. They can post a bond equal to the lien amount, which removes the lien from the title but preserves the owner's right to challenge it in court. Or they can ignore the lien and let it sit, though this prevents any sale or refinancing.

If the lien is not paid or discharged within a certain time, the lien holder can file a lawsuit to foreclose the lien, which means forcing a sale of the property to pay off the debt. This is a serious step and usually leads to settlement before trial.

Lien Priority and Conflicts with Mortgages

A mechanics lien ranks ahead of most other claims against the property, but it ranks behind mortgages that existed before the lien was filed. This is called the priority rule. If a property has a $500,000 mortgage and a $50,000 mechanics lien, the mortgage lender gets paid first from a sale, and the lien holder gets what is left.

However, a mechanics lien ranks ahead of mortgages that are recorded after the lien is filed. It also ranks ahead of judgment liens, tax liens, and other claims filed after the mechanics lien. This priority is one reason mechanics liens are powerful—they often rank ahead of the property owner's own debts.

A construction lender (a lender who finances the construction project itself) may have a mortgage that ranks ahead of mechanics liens. The construction lender's mortgage is recorded before construction begins, so it has priority. This is why construction lenders require the general contractor to obtain lien waivers from all subcontractors and suppliers before releasing payment—the lender wants to may support that no liens will be filed that rank ahead of their mortgage.

Lien Waivers and Conditional Payment

A lien waiver is a document in which a contractor, subcontractor, or supplier agrees to give up their right to file a mechanics lien in exchange for payment. Lien waivers are common in New York construction and are often required by the general contractor or the construction lender before payment is released.

There are two types of lien waivers: conditional and unconditional. A conditional lien waiver states that the waiver is effective only if the check clears or the payment is received. An unconditional lien waiver states that the waiver is effective when ready, regardless of whether the payment clears. In New York, conditional waivers are safer for the party giving the waiver, because if the check bounces, the lien rights are not lost.

A lien waiver should be signed only after payment is received and cleared, not before. Signing a waiver before payment is received is a common mistake that results in loss of lien rights even if the payment never arrives. Many contractors and suppliers have lost their right to file a lien because they signed an unconditional waiver and the check later bounced.

Frequently Asked Questions

Can a property owner remove a mechanics lien without paying it?

Yes, by posting a bond equal to the lien amount with the court. The bond removes the lien from the title and allows the property to be sold or refinanced, but the lien holder can still sue on the bond to recover the debt. The property owner can also file a motion to discharge the lien if the notice of non-payment was not served or the lien was filed late.

What is the difference between a mechanics lien and a judgment lien?

A mechanics lien arises automatically under construction law when work is performed or materials are delivered; a judgment lien arises only after a court enters a judgment for money owed. A mechanics lien ranks ahead of most other claims; a judgment lien ranks behind mechanics liens and mortgages. A mechanics lien must be filed within 90 or 120 days; a judgment lien can be filed anytime after judgment is entered.

Can I file a mechanics lien if I was paid in part but not in full?

Yes. A mechanics lien can be filed for the unpaid portion of the contract price. The notice of lien should state the total amount owed and the amount already paid, so the lien amount reflects only the balance due.

What happens if two contractors file liens for the same work?

Both liens are valid and rank equally in priority. If the property is sold, the proceeds are divided between them based on the amount each is owed. If there is not enough money to pay both in full, they share the proceeds proportionally.

Can a homeowner file a mechanics lien against a contractor who did poor work?

No. A mechanics lien is a tool for contractors and suppliers to recover payment for work performed or materials delivered. A homeowner with a complaint about poor work must sue for breach of contract or file a complaint with the Department of Consumer Affairs if the contractor is licensed. A mechanics lien is not available to homeowners.
