Why You Should File a Mechanic's Lien

In an ideal situation, the general contractor or property owner makes timely payments for completed work. Unfortunately, many construction workers often find themselves fighting for payment.

Some workers choose to forgot their pay to preserve relationships with clients. However, letting clients off the hook means you lose money, leaving you struggling to pay your own bills.

A mechanic's lien for unpaid work is a legal provision that allows you to seek payment. It works by attaching a legal interest to the property. Once attached, the lien achieves the following.

Secures the debt

The lien converts unsecured debt (unpaid work) into a secured debt. Placing an interest in the property is a huge step towards guaranteeing payment.

Also, if the client files for bankruptcy, the secured status gives the debt priority, increasing your chances of getting paid.

Pressures the owner to pay

The presence of a cloud on the title can force the owner to pay up, as it makes it difficult to sell or refinance the property.

Once filed, you can enforce the lien through a lawsuit. Successful lawsuits can lead to foreclosures to pay the debt.

Forces general contractors to act

If the party at fault for nonpayment is a contractor, they will want to act quickly and pay you to avoid delays that could affect their relationship with the owner.

A mechanic's lien can greatly improve your chances of getting paid. The next section discusses how to file a mechanic's lien.

Steps to File a Mechanic's Lien for Unpaid Work

The process of filing a lien starts well before recording it with the county. You should consider securing your payment as soon as you start working on a project.

The process is state-specific, but follows these general steps.

  1. Sending a preliminary notice

    Many (but not all) States require you to send a preliminary notice to the owner, notifying them of your participation in the project and your right to file a lien. Find out whether your State has this requirement, and send the notice within the deadline to avoid invalidation.

  2. Send a Notice of Intent (NOI)

    A notice of intent is different from a preliminary notice. You send a notice of intent after payment is delayed to alert the owner of your intention to file a lien and to give them a chance to pay.

  3. Complete the lien document.

    Obtain a mechanic's lien form and fill in the required details, including the owner's name, the work performed, the amount owed, and relevant dates.

  4. Record the lien

    Find out where you should file the lien. Depending on your State, you may need to file it with the county recorder or the court clerk.

    Depending on the State, you may have 60 days to six months to file the lien. Many States have a 90-day deadline. The countdown usually begins on the day you last worked on the project or delivered materials.

  5. Serve the lien

    Most States require that you serve the owner, contractor, or lender with the lien within a specified time limit.

Quote block: The most crucial aspects of a lien are accuracy and meeting deadlines. If you file a lien containing inaccurate information, you could face a lawsuit. States also follow Strict deadlines for filing and enforcing liens.

Even after recording, a mechanic's lien for unpaid work can expire if you do not enforce it in time. If that happens, you can no longer initiate a lawsuit based on the lien to force a foreclosure on the real estate property.

Who Can File a Mechanic's Lien?

A mechanic's lien covers a broad group of construction workers. It allows even workers who are not in a direct contract with the owner to file and enforce the lien.

The following groups of people can file a mechanic's lien for unpaid work, depending on the jurisdiction.

  • General contractors in a direct contract with the owner
  • Subcontractors working under the general contractor
  • Suppliers of materials used in the construction
  • Laborers working on the project
  • Professionals, such as licensed architects, interior designers, engineers, and surveyors
  • Equipment renters
Note:

Every state has rules stating who can file a mechanic's lien for unpaid work. For example, in California, an unlicensed contractor cannot file a mechanic's lien for work that requires a license.

Legal help is necessary to determine if you should file the lien.

Example of a Mechanic's Lien Filing Process

Let's use California as an example of how to file a mechanic's lien for unpaid work.

Send the 20-day preliminary notice

In California, subcontractors and suppliers must send a preliminary notice within 20 days of starting work on the property. If you skip this step, the owner can succeed in preventing your mechanic's lien.

Direct contractors are not required to send the notice, but it is good practice to do so for added protection.

Record the lien

The next step is to record the lien with the county recorder's office where the property is located. The deadline for filing varies in California depending on whether the owner filed a notice of completion with the recorder's office.

If the owner does not file a Notice of Completion, you have 90 days to record the lien. If they do, general contractors have 60 days, while subcontractors and suppliers have 30 days from the date the owner recorded the Notice.

California law does not require a Notice of Intent (NOI). However, it is good practice to send the notice to give the owner time to pay before recording the lien.

Serve the lien

You have 5 days from the date the lien is recorded to serve the property owner. You should send a copy of the lien and a Notice of Mechanic's Lien via registered mail, certified mail, or first-class mail (CA Civ Code § 8416 (2025)). As the claimant, you must sign and verify the lien.

What Happens After You Get Paid? (Filing a Lien Release)

Once the mechanic's lien serves its purpose and you receive your unpaid compensation, your legal obligations are not quite finished. You must remove the cloud on the property owner's title by a Lien Release Form Failing to do so promptly after receiving payment can result in severe financial penalties and legal liability in many states. To officially clear the property record, you will need to draft, sign, and record a formal release document.
