How to File a Mechanics Lien in California

November 13, 2020

When contractors, subcontractors, and materials suppliers don’t get paid, they can file a California mechanics lien. A mechanics lien is a legal claim on the property for unpaid construction work or supplies. Once claimants file a mechanics lien in California, the owner’s property turns into collateral, allowing claimants to secure the service they rendered or the supplies they provided.

In California, mechanics liens are very effective in prompting quick payments for delinquent accounts with overdue invoices. The power of the lien stems from its ability to tie up and encumber the property. Property owners are made aware that they face financial and legal repercussions in the case the mechanics lien has been filed.

CA law ensures that liens are an option to those who worked or supplied materials to a California construction project. However, note that the state is stringent when it comes to enforcing the law, making it very important to follow instructions on what to do, where to go, and when to file. Not doing so can and likely will nullify your claim.

Are you eligible to file a California mechanics lien?

So you haven’t been paid, and you wonder if you’re eligible to file a California mechanics lien to recover what’s due to you.

If you are a contractor, subcontractor, or supplier in a construction project, you can file a mechanics lien in case of delayed payments or non-payment as long as you have recorded a Preliminary Notice.

Designers, equipment lessors, and laborers also have lien rights in California.

California mechanics lien timeline

In California, the Preliminary 20-Day Notice is the document that secures claimants’ right to lien. As the name suggests, the Preliminary 20-Day Notice in California must be filed within 20 days of the beginning of work. Recording the notice on time ensures the coverage of the mechanics lien in case you have to file one. In this case, it only covers work done or supplies delivered within 20 days of the Preliminary Notice, so it is best to serve it right after you start rendering a service or delivering supplies.

Mechanics lien coverage

To whom you deliver the Preliminary Notice differs on a case to case basis. Refer to the chart below.

Can you file a mechanics lien without a preliminary notice in California?

That depends on your role in a project.

If you are a general contractor or any party who has a direct contract with the property owner, you are allowed to file a mechanics lien in California without first serving a 20-day preliminary notice. However, an exception will apply if the project you are working on is being funded by a construction lender. If a project has a lender, general contractors must serve a preliminary notice before they can successfully record a mechanics lien.

If you are a subcontractor or a material supplier with no direct contract with the property owner, you are required to serve a preliminary notice before recording a California mechanics lien.

If you are a “pure” laborer who has not supplied materials to a project, you do not have to serve a preliminary notice to protect your right to file a mechanics lien. Regardless of whether the project has a lender or not, you are not required to file a mechanics lien without first submitting a preliminary notice to the property owner.

When can I file a mechanics lien in California?

Filing the mechanics lien is a serious step, and the lien laws were written in such a way that ensures that claiming parties have had the chance to pursue payment and that the client has had the opportunity to make the payments.

In California, you can file the mechanics lien if your case satisfies any of the two:

  • You must record the mechanics lien within 60 days (for direct contractors) or 30 days (for other participants) of the owner filing a Notice of Completion* or Notice of Cessation*.
  • In case no notice has been filed, you must record the mechanics lien within 90 days of work completion/last day of work.

It is very important to keep the distinction between the two deadlines mentioned. The 90-day filing period applies when work has been completed, while the 60-day or the 30-day filing periods apply if a Notice of Completion or Notice of Cessation has been recorded.

This means that during project closures for which a valid Notice of Cessation is recorded, the regular 90-day deadline may be cut short.  You need to file a mechanics lien on time, especially if you want to recover your payment during circumstances such as economic downturns.

It’s imperative to note this information because you cannot file a mechanics lien when too much time has already passed after the owner’s records a notice or the project has ended. Even if you do all the steps and get to record the lien with the county, it will be invalid and will not hold up in court.

Also remember that you can only file a lien for work or supplies that have already been delivered. You cannot file a claim for work or supplies that are not due yet.

In addition, you must also ensure that when you record your mechanics lien, your documents must be complete and all the pieces of information required must be included. Some construction participants make the mistake of bringing or mailing erroneous mechanics lien forms, which results in getting their paperwork rejected. Note that this will only delay the mechanics lien process, and could potentially cause you to miss the deadline.

*Notice of Completion A document that owners record with the county that asserts that a construction project has been completed. The Notice of Completion triggers the time period for the recording of mechanics liens and stop payment notices.

*Notice of Cessation A document that owners record with the county that asserts that work has ceased on the project and property location. The Notice of Cessation triggers the time period for the recording of mechanics liens and stop payment notices.

Should you file a California Mechanics Lien?

If you haven’t been paid, yes. The reasons why mechanics liens are powerful is emphasized by its ability to secure collateral (the property) for work performed or supplies delivered but remain unpaid.

It also puts more pressure on the client to settle their dues because when a mechanics lien is filed, the claimant can force a sale or foreclosure if he remains unpaid. This is also the reason why the Preliminary Notice puts claimants in a good position even before the situation is escalated to the point of filing a mechanics lien, because it puts financial risk on the owner as well whereas without lien rights, contractors, subcontractors, and suppliers can be left out in the cold with no resort.

How to file a mechanics lien in California: The cost of getting things wrong

First, it’s important to understand how important it is to get everything right when it comes to filing and recording your California mechanics lien. Any error can and will likely render the lien invalid, nullifying your claim and chance to get paid.

One of the most popular questions when it comes to filing mechanics liens is, “Where do I file it?” As you know, filing the lien in the wrong address or location will invalidate the lien.

Some ways people deliver or file the lien in the wrong location is by getting the addresses wrong in the first place. Before delivering and recording a lien, you must make sure that you have the correct addresses and information for all recipients, so that includes the owner, lender, general contractor, and government office.

There are many cases where claimants try to file the mechanics lien in the wrong government office. In CA, mechanics liens can’t be filed through the state, city, or town offices. To make sure that your lien is properly recorded, it must be filed with the county clerk because property records are kept at county-level in California. Also remember that it must be filed with the clerk of the county where the property is located. If you file a California mechanics lien with the wrong clerk, it will be invalid.

Even though errors like these often come up during the mechanics lien process, they can be addressed as long as you record a mechanics lien in person or through a courier. If you are filing a mechanics lien on your own, you would want to be present just in case your document gets flagged for errors or you find yourself in the wrong office. This way, you will be able to correct the mistakes and still successfully record your mechanics lien.

Following the California mechanics lien law

The process of filing a mechanics lien is adequately outlined in California Civil Code Section 8416 Chapter 4. Understanding it inside and out is vital to ensure that your lien will be valid. Different situations call for specific processes, and the difference begins from filing the Preliminary Notice.

From creating the documents to ensuring the accuracy of information, there’s a lot that goes into ensuring you have a valid California mechanics lien filed.

It usually begins with getting the form from your county clerk’s office, but you can also opt for services like Handle that helps you throughout the whole lien process to get you paid quickly. Doing it yourself can certainly be done as long as you’re especially meticulous with all the information you’re using to fill out the forms and filing the documents.

Ensuring accuracy on your California Mechanics Lien

Rules and requirements for mechanics liens vary for each state and the same goes for the information required. Since accuracy is the number one concern when it comes to filing the mechanics lien, it’s critical to pay attention to differences and not be complacent even when you have experience filing liens in other states.

Unlike other states, California mechanics liens do not require notarization. However, you are required to include a signed and verified written statement that includes all the following information:

  • A statement of the claimant’s demand (what is owed)
  • A statement of the type of work provided by the claimant
  • The name of the property owner
  • The name of the person who employed the claimant (direct client or primary contractor)
  • The exact address including a detailed description of the work site
  • The address of the subcontractor, material supplier, or contractor filing the claim
  • A proof of service affidavit completed and signed by the person serving the lien. The following information must be included in the affidavit:
    • The date, place, and type of work delivered.
    • Facts that support the fact that work was supplied
    • The name, address, and title of the lien recepient
    • Lien delivery method, including the tracking number.
  • A statutorily mandated statement printed in 10-point boldface type.
    • The last sentence must be printed in uppercase, except the website address of the California Contractors’ State License Board, which shall remain in lowercase type.



Upon the recording of the enclosed MECHANICS LIEN with the county recorder’s office of the county where the property is located, your property is subject to the filing of a legal action seeking a court-ordered foreclosure sale of the real property on which the lien has been recorded. That legal action must be filed with the court no later than 90 days after the date the mechanics lien is recorded.

The party identified in the enclosed mechanics lien may have provided labor or materials for improvements to your property and may not have been paid for these items. You are receiving this notice because it is a required step in filing a mechanics lien foreclosure action against your property. The foreclosure action will seek a sale of your property in order to pay for unpaid labor, materials, or improvements provided to your property. This may affect your ability to borrow against, refinance, or sell the property until the mechanics lien is released.


The proof of service affidavit ensures that the lien is served upon the property owner or someone in the capacity to receive on their behalf. The affidavit must be filed along with the lien. Serving the lien may be done through registered mail, certified mail, or first class mail.

The claimant must keep the certificate of mailing and/or the prepaid postage that is addressed to the owner’s residence or place of business, or to the address on file in the building permit. Once the mail is sent, the lien is marked served. Create a copy of the affidavit for the owner and another for filing.

How much does it cost to file a Mechanics Lien in California?

The cost for filing a mechanics lien in California varies depending on the county, but it generally ranges between $20 and $50, plus a Building Homes and Jobs Act recording fee of $75, as of January 2018. Some counties also charge a real estate fraud fee that can cost anywhere between $3 and $10. Before you file a mechanics lien, it is a good business practice to call the county clerk’s office ahead and inquire about the exact filing costs applicable to you.

You may also consider using lien filing services instead of doing the filing yourself. There are benefits to both filing a mechanics lien on your own and filing a mechanics lien through a third-party service.

Filing directly using your resources is cheaper but it will require you to ensure that you strictly follow every applicable rule. Using lien filing services costs more, but a good third-party mechanics lien service would have the expertise to do all proper verification measures to ensure that your mechanics lien is successfully recorded.

Note that even though filing a mechanics lien costs some money, you may be able to recover those costs if you end up having to enforce your California mechanics lien. If a property gets foreclosed after you successfully enforce a mechanics lien, you are allowed to claim not only the unpaid amount for your services but also the money that you spent on recording a mechanics lien.

How to record a California Mechanics Lien

Once you have the document together, here are the steps you should take to make sure you have an officially recorded California mechanics lien:

  1. Sign and verify the mechanics lien, produce at least two copies
  2. Send a copy of the lien to the owner and other parties involved in the project 
  3. File a copy of the mechanics lien to the county recorder. There is a filing fee that needs to be paid.


  • California requires mechanics liens to be delivered to the county recorder where the site of the project is
  • The mechanics lien may be filed via mail, private courier (FedEx, UPS, etc.), or via walk-in. You can also file the mechanics lien online through Handle.
  • Include the filing fees and a self-addressed envelope with return instructions for mailed in liens.
  • Ask the county clerk about the fees.
  • Keep a stamped copy of the recorded lien after recording

mechanics lien steps

The stamped copy of the recorded lien in your possession is proof of officially recording your California mechanics lien as long as you served the document to the property owner prior to submitting the document for recording with the county clerk.

Ensuring that you have proof of delivery and/or recording for all copies of the lien is important because non-delivery to the required recipients is a surefire way to invalidate your lien. Per CA Civil Code 8416, Article 2,

(e) Failure to serve the copy of the claim of mechanics lien as prescribed by this section, including the Notice of Mechanics Lien required by paragraph (8) of subdivision (a), shall cause the claim of mechanics lien to be unenforceable as a matter of law.

But, always remember that an officially recorded California mechanics lien doesn’t ensure that it is valid. If there were errors in the document or if your Preliminary Notice was incorrectly recorded, your mechanics lien will likely be invalidated. In case it goes through the county clerk and is deemed valid, the property owner can easily challenge it and the error ensures a decision favoring the other side, removing your claim on the property.



The owner paid. What should the claimant do?

The California mechanics lien must be canceled and removed from the county record by the claimant with the county clerk.

What if they don’t pay after sending a mechanics lien?

Before anything else, take note that lien foreclosures are extremely rare as the percentage of mechanics liens that get paid off fast is very high. Any enforcement of the lien or lien foreclosure is often unnecessary.

The right to claim against the client’s property is the most powerful feature of the California mechanics lien, and is why it’s essential that you’re filing everything the right way.

Putting pressure on the owner to pay while giving them a way to avoid going into court is what the lien seeks to accomplish. If they haven’t responded to previous times that you’ve tried to collect, the California mechanics lien is a surefire way to get their attention and, by extension, to get them to pay you. If not, they know they’re facing a court case.

While court cases are something that you will likely win with a properly filed mechanics lien, everybody wants to avoid the frustration and issues that are involved in them. But, as with anything, sometimes they’re not avoidable.

What happens next? Pursuing Lien Foreclosure

Still nothing? After recording the lien, you have 90 days to begin an action to foreclose the lien. If you’re not able to commence the action within 90 days, the lien expires rendering it unenforceable.

The process of filing a lien foreclosure is similar to the standard procedure of filing any other lawsuit. You need to secure a legal filing, and then present a case outlining and explaining why you’re owed the amount you state in the foreclosure.

The claimant (you) must file a Complaint for Foreclosure to the property owner and to all other claimants who have lien rights on the property. It’s common for all claimants going after the same non-paying client to merge their claims and push for a single action.

After notifying the property owner of your action to pursue lien foreclosure, you must also record a lis pendens or a Notice of Pending Action with the country recorder where the property is recorded. The Notice of Pending Action notifies prospective purchasers and lenders of the foreclosure action.

After all the notices go out, a court will schedule to hear the case to resolve the claims and decide who gets paid first, in case there are several claimants. This is very important because there are cases where the property’s sale value is not enough to pay all liens.

If at least one of the claimants can prove in court that their liens are valid and that they have a legal claim over the property, the court will facilitate a sale of the owner’s property. The proceeds will then be used to pay the claims.

The Owner’s Defense

Is a valid mechanics lien an assurance that you’ll get paid? Yes — as long as it’s valid.

Now, the validity is not only about filing the documents on time and getting the correct names and addresses on them.

The owner can and will dispute your mechanics lien. One of the most popular defenses of owners again lien foreclosure is proving that the amount a claimant has stated in the lien exceeds the actual contract price for the work or that the work claimed in the lien was not accomplished or delivered doesn’t satisfy the claimant’s part of the construction contract.

This means you shouldn’t proactively include projected lawyer’s fees in the contract price you include in the notice or the mechanics lien. Doing this will invalidate your mechanics lien. Don’t worry, if you successfully foreclose on a California mechanics lien, the court may award you the cost of filing and recording the lien and the attorney’s fees as well.

It’s essential to have a competent lawyer on your side because, despite the law being on your side, a foreclosure still involves serious litigation requiring technical expertise. Just like the whole lien process, a simple error in the requirements can invalidate your claim if the law is not followed to the t.

From filing the Preliminary 20-day notice and the California mechanics lien to, in some cases, pursuing litigation, CA law is very strictly enforced. To get paid faster and have all options secured in case a client proves delinquent, it’s important to have an ironclad process that protects you from seemingly small but dangerous errors that are fatal to your right to get paid on time and in full.

The Owner’s Move: Lien release bond

Another possible outcome is the owner moving to prevent foreclosure on their property by moving to secure a mechanics release bond. The owner can obtain a mechanics lien release bond (CA Civil Code Section 8424) by securing a surety bond in favor of a lien claimant for 125% of the lien amount. The bond must be liquid. In other words, the amount must be in cash. The way this works is that the lien will be placed on the bond instead of the property, freeing up the property to be eligible for sale or financing without liens on paper. In this case, the owner still needs to defend the foreclosure action so they don’t lose their money held in bond.


Getting paid on time and protecting your lien rights in case of a delinquent account is crucial, and you must ensure that you don’t hurt your interest by making errors in the process. Using a service like Handle will help you get paid faster and make sure you file error-free notices and mechanics liens. Embracing technology is the best way to avoid losing money on contracts due to small clerical errors when securing your lien rights and even when enforcing them.
