To file a lien on a property, you confirm you have a legal basis for the claim, prepare a written claim of lien with the property’s legal description and the exact amount owed, record it with the county recorder’s office where the property sits, and serve the owner with notice — all within deadlines that vary by state and lien type. The mechanics are similar whether you’re a contractor who hasn’t been paid, a creditor holding a court judgment, or a government agency, but the deadlines and required documents differ, and missing any one of them can void the lien entirely.
Confirm You Have the Right to File
Not everyone owed money can file a lien. Your basis has to fit one of the recognized categories.
The most common filer is a contractor, subcontractor, or material supplier who performed work or delivered goods for a construction project and hasn’t been paid. Their tool is the mechanic’s lien, sometimes called a construction lien. Most states allow these liens for new construction, renovations, and repair work, though eligibility requirements vary by jurisdiction.
A creditor who wins a lawsuit can file a judgment lien, which attaches to the debtor’s real property and blocks a clear transfer of title until the judgment is satisfied. Judgment liens don’t require any connection to construction; they arise purely from a court’s monetary award.
Government entities file their own liens. The IRS places a federal tax lien on all property belonging to anyone who fails to pay taxes after a demand for payment.1Office of the Law Revision Counsel. 26 U.S. Code 6321 – Lien for Taxes Homeowner associations can file liens for unpaid dues, and local governments file for unpaid property taxes.
One boundary matters upfront: you cannot file a mechanic’s lien on property owned by the federal government. Federal property is immune. On federal public projects exceeding $100,000, contractors must post a payment bond that stands in for lien rights under the Miller Act.2Office of the Law Revision Counsel. 40 USC 3131 – Bonds of Contractors of Public Buildings or Works If you worked on a government job, your remedy is a bond claim, not a lien, and you generally have one year from your last day of labor or materials to sue on the bond.3Office of the Law Revision Counsel. 40 USC 3133 – Rights of Persons Furnishing Labor or Material
Send a Preliminary Notice First
Most states require anyone planning to file a mechanic’s lien to send a preliminary notice to the property owner, the general contractor, or both before recording anything. The notice isn’t the lien. It tells the owner you’re on the project and preserves your right to file later if you aren’t paid.
Deadlines vary. Some states require the notice within 20 days of starting work or delivering materials. Others have longer windows, and a handful don’t require preliminary notice at all. Where notice is required, failing to send it — or sending it late — can strip your lien rights entirely or limit any future claim to work performed after the notice was finally sent. Check your state’s rule before you start work, not after payment stops.
Some states also require a separate notice of intent to lien in the days before recording, giving the owner one last chance to pay. Where that step exists, it has its own deadline and delivery requirements, and skipping it is fatal to the claim.
Prepare the Claim of Lien
The lien itself is a formal document, often called a claim of lien or lien statement. Details matter more here than almost anywhere else in the process, because errors can make the lien unenforceable. At a minimum, the document typically has to include:
- Your name, address, and business identity as the claimant.
- The property owner’s name as it appears on the deed, not just the person who hired you.
- The legal description of the property, taken from county records or the deed. A street address alone usually will not do.
- The specific dollar amount you are owed.
- A description of the labor or materials you provided, with the general dates of the work.
- A sworn statement affirming the claim is accurate and made in good faith.
Some states require notarization. Others require specific statutory language or an official form. The legal description is where most filers stumble; pull it from the county assessor’s records or the deed rather than guessing from an address.
Record It With the County
Once the document is ready, you record it with the county recorder’s office (in some places called the county clerk) in the county where the property sits. Recording creates a public entry that attaches to the property’s title. That is what gives the lien its real force: anyone running a title search will see it, which makes selling or refinancing the property difficult until the lien is cleared.
Filing fees are usually modest, often in the range of $15 to $50 per document depending on page count and local fee schedules. You can typically file in person, by mail, or electronically where the county supports it. Certified mail or an electronic confirmation gives you proof of the filing date, which is important because of the deadline.
Filing deadlines are strict. Depending on the state, you may have as little as 60 days or as long as a year after the last day you provided labor or materials, with most windows falling between 90 and 180 days. File one day late and the lien is void. There are no extensions.
Serve Notice on the Property Owner
After recording, most states require you to send a copy of the lien to the property owner within a set number of days. Some states also require notice to the general contractor, the construction lender, or both. The typical window is 5 to 30 days after filing, depending on jurisdiction.
Send the notice by certified mail with return receipt requested, or by another method that creates a paper trail proving delivery. Many states require you to file proof of service, an affidavit confirming that the owner was notified, along with or shortly after the lien itself. If you cannot prove the owner received notice, a court can invalidate the lien later.
Enforcing the Lien if You Still Aren’t Paid
Recording a lien does not automatically get you paid. It secures your claim against the property. If the owner still refuses to pay, enforcement means filing a separate lawsuit asking a court to foreclose on the lien and order the property sold at auction, with the proceeds applied to your claim.
You have a limited window to bring that suit after recording. Deadlines range from as short as 90 days to as long as several years depending on the state, with most falling between six months and two years. Miss the window and the lien expires. The underlying debt may still exist, but the property is no longer collateral.
Foreclosure litigation is expensive and slow. You’ll need to prove the debt is valid, that you complied with every filing requirement, and that the lien was properly recorded and served. The owner will almost certainly contest either the validity of the lien or the amount claimed. Homestead exemptions in many states can shield a primary residence from forced sale to satisfy a judgment lien, though mechanic’s liens and tax liens are commonly exempt from that protection, meaning the home can still be sold even if the owner lives there.
Where Your Lien Sits in Line
When a property is sold or foreclosed, liens are paid in a specific order, and there is rarely enough money for everyone. The general rule is “first in time, first in right”: the lien recorded earliest gets paid first.4Internal Revenue Service. Priority of Federal Tax Lien: First in Time, First in Right A mortgage recorded before your mechanic’s lien takes priority, and the mortgage holder collects before you see a dollar.
Property tax liens generally take absolute priority regardless of when they were recorded. Federal tax liens also carry significant weight, though their priority against other liens depends on when the IRS files its notice.4Internal Revenue Service. Priority of Federal Tax Lien: First in Time, First in Right In some states, mechanic’s liens “relate back” to the date construction began rather than the date the lien was recorded, which can put them ahead of mortgages recorded after work started. This varies significantly by state and is one reason your recording date matters.
Know where you fall in the stack before spending money to enforce. A lien in third or fourth position behind a large mortgage may recover little even after a successful lawsuit.
A Note on Judgment Liens
If you already have a court judgment against the debtor, the mechanic’s-lien process doesn’t apply. You record a certified copy of the judgment abstract with the county recorder in any county where the debtor owns property. Once recorded, the lien blocks the debtor from selling or refinancing without addressing your judgment.
Federal judgment liens last 20 years and can be renewed once if you file a renewal notice before the first period expires and the court approves.5Office of the Law Revision Counsel. 28 USC 3201 – Judgment Liens State-level judgment liens are shorter, commonly 5 to 10 years, though many states allow renewal.
Release the Lien Once You’ve Been Paid
When the debt is paid, you are legally required to release the lien. That means filing a lien release or satisfaction document with the same county recorder’s office that recorded the original. The release clears the cloud on title so the owner can sell or refinance.
Release deadlines vary. Some states require immediate release upon payment. Others give you 10 to 60 days, either from the date of payment or from when the owner sends a written demand. Sitting on a release carries real penalties, which depending on the state can include per-day fines, liability for the owner’s actual damages, and court-ordered attorney fees. In some jurisdictions the penalties can exceed the original lien amount.
Don’t File a Lien You Aren’t Entitled To
Filing a lien you have no right to file, or inflating the amount, is a fast route to a countersuit. A property owner who proves the lien was filed in bad faith can bring a slander of title claim, which requires showing the lien was false, that you knew it was false or seriously doubted it, and that the false lien caused financial harm. Damages can include the drop in sale price, holding costs while the property sat unsaleable, attorney fees, and in some states punitive damages.
Beyond civil liability, some states treat filing a knowingly false lien as a criminal offense, with possible felony charges, fines, and jail time. Licensed contractors also risk suspension or revocation of their license. File only when the claim is legitimate and documented, and only for the amount actually owed.
