It happens all the time. A GC calls you on a Tuesday, says "I need you on the job Thursday, we'll sort the paperwork later," and the paperwork never comes. You do the work, the invoice goes unpaid, and now someone is telling you that without a signed contract you have no lien rights. That someone is usually wrong.
In most states, a mechanics lien attaches because you furnished labor or materials that improved the property, not because you signed a piece of paper. Contracts don't have to be in writing to support a lien claim. What you need is to show that your work was requested or authorized by the owner or someone acting for the owner, like the general contractor. A handshake deal with the GC, a verbal agreement, a string of text messages saying "yes, do it", all of that can be a contract in the eyes of lien law. Maryland's lien statute is unusually blunt about it: the contract can be any agreement for goods or services, and it need not be written down (see the Maryland People's Law Library summary of Md. Code, Real Property §§ 9-101 through 9-103).
Levelset's attorneys have answered this one directly for Arizona and Wisconsin: yes, a sub can file with a verbal agreement, and Wisconsin subs have lien rights regardless of whether there was a formal contract at all. The principle is national. A longer explainer of what counts as a valid contract for lien purposes is at Levelset's contract eligibility guide.
Watch: what counts as a valid contract for a mechanics lien, and why a written agreement with the owner isn't required in most situations.
What "no contract" usually means (three flavors)
People say "I don't have a contract" and mean three very different things. Only one of them is actually a problem.
1. You have a deal with the GC, but nothing written. This is the most common situation and the least dangerous. A verbal agreement is still an agreement. The law calls it an implied or oral contract, and it supports a lien just fine in most states. Your challenge is proof, not rights.
2. You never dealt with the owner at all. Also fine, and also normal. That's what being a subcontractor means. Your contract is with the GC, and the GC's contract is with the owner. Lien law is specifically built for this: the whole point of a mechanics lien is that it reaches past the person who hired you and attaches to the property itself. You do not need privity (a direct contractual relationship) with the owner.
3. The work was never authorized by anyone. This is the one that kills you. If you showed up and did work nobody asked for, there is no contract of any kind, implied or otherwise, and there is no lien. The work has to have been requested by the owner or the owner's agent. "The GC told me to do it" counts. "I noticed the trim needed fixing and did it on my own initiative" does not.
The catch: proving scope and price
Here's the honest part. Having the right to lien and winning on a lien are different things, and without a written contract the second one is harder. A written contract does two jobs for you: it proves what you were supposed to do (scope), and it proves what you were supposed to be paid (price). Without it, you're reconstructing both from evidence.
When there's no agreed price, the law generally falls back on the reasonable value of the work you performed. Lawyers call this quantum meruit, which is Latin for "as much as deserved." In practice it means: what would this work fairly cost, given what you did, the materials you used, and the going rates? That's a workable standard, but it's squishier than pointing at a signed number, and it gives the other side room to argue your work was worth less than you say.
Change orders are where this gets expensive. Without a written contract you almost certainly don't have written change orders either, and disputed extras are the number-one fight in no-contract lien cases. "He told me to add the recessed lighting" is a claim. A text from the GC saying "yes, add the recessed lighting, I'll pay the extra" is evidence. See the difference.
So the catch isn't that you can't file. The catch is that your paperwork has to do the job your contract would have done. Which brings us to the checklist.
The documentation checklist that wins
If you're working without a written contract, or you already did and you're now chasing payment, start building this file today. Every item below is something a judge or an arbitrator actually looks at:
- Anything in writing about the deal: texts, emails, DMs where the work, the price, or the schedule was discussed or approved.
- Photos of the work in progress and the finished work, ideally timestamped. Take more than you think you need.
- Daily logs or timesheets: who was on site, what got done, which dates.
- Delivery tickets and material receipts tied to the project address.
- Your invoices, sent on time and kept in order, with invoice numbers and dates.
- Proof the GC or owner knew you were there: site sign-in sheets, emails copying you, payment applications listing your company.
- Change-order evidence: texts or emails approving extra work, before-and-after photos of the extras.
- Names of witnesses: your crew, other trades on site, the owner's rep, anyone who saw the work happen.
- Your license, if your state requires one for your trade (see the trap below).
The theme: you are proving two things, that the work was authorized and that the amount is fair. Authorized is proved by communications and presence on site. Fair is proved by invoices, receipts, and rates. Build both piles.
What if the GC got paid but you didn't?
This deserves its own mention because it's the scenario that angers people the most, and it's fully covered by lien law. The owner paid the GC in full. The GC pocketed your share. Now the owner says "I already paid for this work, I'm not paying twice," and the GC has stopped answering the phone.
File anyway. The lien attaches to the property, not to the GC's bank account, and the owner's beef is with the GC, not you. This is exactly why Texas has the monthly fund-trapping notice: if you sent your notices on time, the owner was supposed to hold back enough to cover you instead of handing it all to the GC. An owner who paid the GC in full after receiving your notice has a much harder time fighting your lien. And in Florida and several other states, the same principle applies through the notice-to-owner system. The money trail between the owner and the GC is their problem. Your work is in the building, and that's what the lien secures.
Trap 1: the license problem
This is the big one, and it has nothing to do with contracts. Some states won't let an unlicensed contractor lien at all, or even sue for payment, no matter how good the work was.
California is the famous example. Under Business and Professions Code § 7031, an unlicensed contractor generally cannot bring any action to collect compensation for work that required a license, and that bar extends to mechanics liens. California courts have enforced this strictly: the statute puts the risk squarely on the unlicensed contractor, regardless of how good the work was. If you're doing work in California that requires a license and you don't have one, the contract question is beside the point. Fix the license first.
Other states have their own versions of this rule with different teeth. Before you file anywhere, confirm two things: whether your trade needs a license in that state, and whether the lack of one affects lien rights. This is a five-minute check that saves people from filing liens that were dead before the ink dried.
Trap 2: the homestead and home-improvement exceptions
A few situations specifically demand a written contract, and they're worth knowing by name.
Texas homesteads. Texas is the strictest. To lien a homestead (the owner's primary residence), Section 53.254 of the Property Code requires a written contract executed before work begins, signed by both spouses if the owner is married, and recorded with the county clerk. No written pre-work contract, no lien, and the failure poisons downstream subs too. Our Texas filing guide covers this trap in detail.
Home-improvement contract rules. Several states have consumer-protection laws requiring written contracts for residential home-improvement work, sometimes above a dollar threshold. These rules are usually about the contractor's ability to enforce the contract against the homeowner, and they don't always kill lien rights, but they can complicate them. If your job is residential remodeling, check your state's home-improvement contract requirements separately from its lien statute.
What to do right now if you're unpaid without a contract
Don't wait for the paperwork situation to get better. It won't. Work the process:
- Send a notice of intent to lien. This is your demand letter with teeth, and it works fine without a written contract. Our free NOI template is built for exactly this situation. Send it certified mail, keep the receipt.
- Calendar your filing deadline and work backwards. Lien deadlines are measured from your last day of work or from project completion, depending on the state, and they do not care about your contract situation. Find your state's deadline in our 50-state deadline hub and treat it as sacred.
- Keep building the evidence file. Every item on the checklist above. If the dispute is already hot, write down your recollection of the verbal agreement now, while it's fresh: who said what, when, where, who else was there.
- File the lien on time, for an honest amount. Claim what you're actually owed for work actually performed. Without a contract to point at, an inflated number destroys your credibility fast.
- Talk to a construction attorney before the deadline gets close. Not because you can't file yourself, but because no-contract cases have more ways to go sideways: disputed scope, disputed price, authorization fights. An hour of advice at the start is cheaper than a blown lien at the end.
And going forward: get it in writing. Not a twenty-page contract drafted by a lawyer. A one-page scope, a price, a signature, and a text saying "confirmed." The GCs who won't sign a one-pager are telling you something. Listen to them before you mobilize, not after you're unpaid.
One more thing worth knowing: even if your lien deadline has passed or your lien rights are shaky, you may still have other ways to get paid, like suing on the oral contract itself or, in some states, an unjust-enrichment claim for the value of the benefit you conferred. A plain-English explainer of unjust enrichment covers how that fallback works. And Nevada's lien FAQ puts the underlying principle nicely: it is enough that the labor or materials were provided at the instance or request of the owner or the owner's agent (see LienItNow's Nevada FAQ). The work is what matters. The paper just makes proving it easier.
Not legal advice
Mechanics lien laws are state-specific and they change. Deadlines, notice rules, and forms differ by state and by your role on the job. This guide is general information — before you act on a deadline, confirm it with a construction attorney in your state. Missing a deadline by even one day can kill your lien rights.
