How to File a Lien: A Subcontractor's Guide
Last updated: July 2025
To file a mechanics lien, a subcontractor must complete three stages in the correct sequence: serve any required preliminary notice before the statutory deadline, record a mechanics lien claim with the county recorder's office in the county where the property is located, and then enforce the lien by filing suit before the enforcement deadline expires. Preliminary notice deadlines typically run 20 days from first furnishing labor or materials (e.g., Cal. Civ. Code § 8200; Ariz. Rev. Stat. § 33-992.01), though windows vary by state from 20 to 45 days. Mechanics lien recording deadlines generally fall between 60 and 120 days after completion of the work or project. Missing any one of these deadlines — especially the preliminary notice — is a complete bar to lien rights in most states.
What Is a Mechanics Lien and Why Does It Matter for Subcontractors?
A mechanics lien is a legal claim against real property that secures a subcontractor's right to be paid for labor or materials furnished to improve that property. It attaches to the title of the property itself — not just to the contractor who hired you — which means the property owner has a direct financial stake in resolving your unpaid claim.
That leverage is real. A recorded lien clouds the title, blocking the owner from selling or refinancing until the lien is released or bonded. That creates pressure at every level of the payment chain to get you paid. Without a lien, a subcontractor is an unsecured creditor — you're in line behind everyone else if the GC or developer runs out of money or goes bankrupt.
According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. Mechanics lien rights exist precisely because the construction payment chain is long, slow, and often fails the people who did the actual work.
What Are the Steps to File a Mechanics Lien?
Filing a mechanics lien follows a defined sequence of steps that cannot be reordered. Here is the process from start to finish.
Step 1: Serve the preliminary notice (where required)
Most states require subcontractors — who have no direct contract with the property owner — to serve a preliminary notice before lien rights activate. This notice informs the owner that you are working on their property and preserves your right to lien. Serve it within the statutory window from your first day on the job or first material delivery. More on specific deadlines below.
Step 2: Track your last day of work
Your lien recording deadline runs from the last day you furnished labor or materials — or in some states, from completion or abandonment of the overall project. Document your last furnishing date with timestamps, delivery receipts, or job logs. Do not rely on memory.
Step 3: Prepare the lien claim document
Every state has specific content requirements for a valid mechanics lien. At minimum, a lien claim typically must include:
- The claimant's name and address
- The name of the person who hired you (the GC or owner)
- The property owner's name
- A legal description of the property (not just the street address)
- The amount claimed
- A description of the labor or materials furnished
- The date of first and last furnishing
- Claimant's signature, often notarized
Errors in any required field can void the lien. Use a state-specific, attorney-reviewed template rather than a generic form.
Step 4: Record the lien with the county recorder
Take the completed, notarized lien document to the county recorder's office (sometimes called the Register of Deeds) in the county where the property is physically located. Pay the recording fee — typically $10–$30 per page, depending on the county. The recorder stamps the document with a recording number and date, which is the official date your lien attached to the property.
Step 5: Serve a copy of the recorded lien on the owner
Several states require you to serve a copy of the recorded lien on the property owner within a set number of days after recording. In Florida, for example, a copy must be served within 15 days of recording under Fla. Stat. § 713.08(4)(c). Failure to serve can render the lien unenforceable even if it was properly recorded.
Step 6: Enforce the lien before the enforcement deadline
Recording the lien does not automatically get you paid. You must file a lawsuit to enforce the lien within the statutory enforcement period — typically 1 year from recording in most states, though it is 90 days in Arizona (Ariz. Rev. Stat. § 33-998) and 1 year in California (Cal. Civ. Code § 8460). If you do not file suit in time, the lien expires and you lose your rights.

What Is a Preliminary Notice and Do You Always Need One?
A preliminary notice (also called a pre-lien notice, notice to owner, or notice of right to lien depending on the state) is a written notice served early in the job that preserves your right to record a mechanics lien later. In most states, subcontractors who do not have a direct contract with the property owner are required to serve this notice or they lose their lien rights entirely.
The following table summarizes preliminary notice requirements across the states LienFlash covers:
California — Required. Serve within 20 days of first furnishing. Governs under Cal. Civ. Code § 8200. Late service limits lien rights to the 20 days before service was made.
Florida — Required for subcontractors and suppliers not in privity with the owner. Serve within 45 days of first furnishing under Fla. Stat. § 713.06(2)(c). No notice, no lien.
Arizona — Required. Serve within 20 days of first furnishing under Ariz. Rev. Stat. § 33-992.01. Late service covers only work furnished after the 20-day window before service.
Nevada — Required. Notice of Right to Lien must be served within 31 days of first furnishing under NRS § 108.245. Failure bars lien rights.
Washington — Required. Notice of Right to Claim Lien must be served within 60 days of first furnishing under RCW § 60.04.031. Late service limits protection.
Oregon — Required. Notice of Right to a Lien must be served within 8 business days of first furnishing under ORS § 87.021. This is one of the shortest windows in the country.
Texas — Required, with a complex monthly notice system under Tex. Prop. Code § 53.056. Subcontractors must serve notice by the 15th of the third month following each month unpaid work was performed.
New Mexico — No preliminary notice required for subcontractors to preserve lien rights, but a Notice of Claim must be filed within 120 days of last furnishing under NMSA § 48-2-7.

What Are the Mechanics Lien Recording Deadlines by State?
The recording deadline is the date by which the completed lien document must be filed with the county recorder. Missing it permanently extinguishes your lien rights for that project.
California — 90 days after completion of the project (or 60 days after a Notice of Completion is recorded) under Cal. Civ. Code § 8412–8414.
Florida — 90 days after the final furnishing of labor or materials under Fla. Stat. § 713.08(5).
Arizona — 120 days after substantial completion of the project under Ariz. Rev. Stat. § 33-993.
Nevada — 90 days after the last day of furnishing under NRS § 108.226.
Washington — 90 days after the last day of furnishing under RCW § 60.04.091.
Oregon — 75 days after the last day of furnishing under ORS § 87.035.
Texas — The deadline varies based on whether the project is commercial or residential and whether a Notice of Termination has been filed; generally, lien claims must be filed by the 15th day of the fourth month after the work was performed (commercial) under Tex. Prop. Code § 53.052.
New Mexico — 120 days after last furnishing under NMSA § 48-2-7.
These are not soft deadlines. Courts have consistently refused to grant extensions for administrative errors, mailing delays, or a claimant's lack of knowledge about the rules.
What Information Must Be in a Mechanics Lien Claim?
A mechanics lien claim is valid only if it contains every element the state statute requires. The specific requirements vary, but the universal core elements are:
- Claimant identification — your legal business name and address exactly as registered
- Property owner name — the person or entity holding title, not just who hired you
- Hiring party — the GC or subcontractor who contracted with you
- Property description — the legal description from the county's property records, not just the street address
- Amount claimed — the unpaid balance owed, which must be accurate; overstating the amount can expose you to a penalty lien claim in some states
- Labor/materials description — a brief description of work performed or materials supplied
- Date of first and last furnishing
- Claimant signature — notarization is required in most states
Some states add specific requirements. Florida requires that the lien include a warning notice to the owner in specific statutory language under Fla. Stat. § 713.08(1). California requires the claimant to state whether a payment bond was recorded for the project. Always use a state-specific template reviewed by a licensed attorney.
How Much Does It Cost to File a Mechanics Lien?
The total cost to file a mechanics lien has three components: document preparation, recording fees, and mailing/service costs.
Document preparation — If you use an attorney, expect $200–$500 or more per lien. If you use a compliant software service, costs are significantly lower. LienFlash charges $24.99 per preliminary notice with attorney-reviewed, state-specific forms included. Lien recording document preparation varies by provider.
County recording fees — Most counties charge $10–$25 for the first page and $2–$5 per additional page. Budget $25–$75 for recording fees depending on your state and county.
Service and mailing — Preliminary notices and lien copies must typically be served by certified mail or personal delivery. USPS Certified Mail costs $4.85 as the base fee in 2026 (per USPS Notice 123, effective 2026), plus standard postage and any return receipt fees.
The math on protection versus cost is not complicated. A single preliminary notice at $24.99 — if it preserves lien rights on a $15,000 subcontract that would otherwise go unpaid — represents a 60,000% return on that filing cost. That figure climbs above 300,000% on a $75,000 contract. The risk of not filing is not financial — it is the complete, permanent loss of your right to use the lien process at all.
What Happens After You Record a Mechanics Lien?
After recording, you have a security interest in the property — but the lien is not self-executing. You have three main paths forward.
Path 1: The owner or GC pays you. This is the most common outcome. A recorded lien creates enough pressure on the title that most disputes resolve in payment or a negotiated settlement before enforcement ever begins. The property can't sell or refinance cleanly with your lien on it.
Path 2: You enforce the lien in court. If payment does not come, you must file a lawsuit to foreclose on the lien within the statutory enforcement window. The court can order the property sold to satisfy your claim. Hire a construction attorney for this step — lien foreclosure litigation is not a DIY process.
Path 3: Your lien expires uncontested. If you do nothing after recording, the enforcement deadline will pass and your lien will expire, leaving you with nothing. Calendar the enforcement deadline the day you record.
One additional scenario: the owner or GC can bond off the lien, substituting a surety bond for the lien's security interest. This releases the cloud from the title but shifts the dispute to the bond. You then have a claim against the bond rather than the property — but your lien rights against the bond are preserved.
Frequently Asked Questions
Can I file a mechanics lien if I don't have a written contract?
Yes. Most state lien statutes do not require a written contract to support a valid mechanics lien. An oral agreement to furnish labor or materials is generally sufficient. What matters is that you actually furnished value to the project and were not paid. That said, a written contract, purchase orders, and delivery receipts will significantly strengthen your claim if the lien is disputed or you need to foreclose.
What is the difference between a preliminary notice and a mechanics lien?
A preliminary notice is a pre-lien notice served early in the job to preserve the right to file a lien later. A mechanics lien is the actual recorded claim against the property filed after non-payment occurs. The preliminary notice does not create a lien — it is a condition precedent that keeps the lien option open. In most states, skipping the preliminary notice permanently eliminates the right to file a mechanics lien, regardless of how valid the underlying payment claim is.
Can a subcontractor file a lien even if the GC is disputing the work?
Yes. A mechanics lien can be filed whenever there is an unpaid claim for labor or materials actually furnished. The GC's dispute does not bar the filing. The dispute goes to the merits of the underlying debt — it does not affect your right to record the lien and create a security interest. Record the lien to preserve your rights, then work to resolve the payment dispute separately.
What if I missed the preliminary notice deadline?
In states where the preliminary notice is mandatory, missing the deadline generally means you cannot file a valid mechanics lien for the work furnished before the notice was served. Some states allow late service that limits protection to work performed within the 20 days before service (California, Arizona). Others are a complete bar from day one. If you missed the deadline, consult a construction attorney immediately — there may be alternative remedies such as a bond claim, breach of contract claim, or prompt payment act claim available.
Does filing a mechanics lien hurt my relationship with the GC?
That is a business decision only you can make. What is clear is that failing to protect your payment rights does not improve the relationship — it just removes your leverage. Most experienced GCs understand that lien rights exist and are used in the industry. Many subcontractors serve preliminary notices on every job as a matter of routine — it signals professionalism, not aggression. A recorded lien on a disputed job is a different level of escalation, but at that point, the relationship is already strained.
How long does a mechanics lien stay on the property?
The duration depends on state law and whether the lien is enforced. In most states, an uncontested, unenforced lien expires after 1 year from recording if no lawsuit is filed. In Arizona, the enforcement window is only 90 days from recording under Ariz. Rev. Stat. § 33-998. Once expired, the lien has no legal effect and should be released. If you do not release an expired lien, the owner may take legal action to force a release and recover attorney's fees.
Do I need an attorney to file a mechanics lien?
You are not legally required to use an attorney to record a mechanics lien in most states. However, any errors in the lien document — wrong legal description, incorrect claimant name, overstated amount — can void the lien entirely or expose you to counterclaims. Using attorney-reviewed, state-specific templates is the minimum standard. For lien enforcement (foreclosure litigation), an attorney is effectively required — the procedural and substantive complexity of lien foreclosure is not manageable as a pro se litigant in most jurisdictions.
Can I file a lien on a public project?
No. Mechanics liens cannot be recorded against government-owned property (federal, state, or municipal projects) because the government holds sovereign immunity from lien claims. On public projects, the equivalent protection is a payment bond claim under the Miller Act (federal projects, 40 U.S.C. § 3131 et seq.) or the applicable state Little Miller Act. Bond claim deadlines are typically 90 days from last furnishing on federal projects. These are entirely separate from the mechanics lien process and have their own notice and claim requirements.
Protect Your Lien Rights Today
The single biggest mistake subcontractors make is waiting until they have a payment problem to think about lien rights. Preliminary notice deadlines start running the day you first set foot on the job or make your first delivery — not the day someone stops returning your calls. By the time a payment dispute surfaces, the deadline to preserve your rights may already be gone.
