What Is the Written Contract Requirement for a Mechanics Lien?
Every mechanics lien statute ties the lien to some relationship with the property owner: work furnished under a contract with the owner, at the owner's request, with the owner's consent, or through a chain of contracts running back to the owner. The written contract requirement is the question of whether that relationship has to be on paper and signed before the lien exists. Statutes answer it in one of four ways. Some require a writing, for everyone or for particular claimants or projects. Some expressly recognize unwritten contracts with words like express or implied, oral or written, written or unwritten, or in writing or parol. The rest are silent on form: California's Civil Code section 8404, for example, treats work as authorized if it is provided at the request of or agreed to by the owner, with no mention of paper. Silence is not a prohibition; where a statute requires only a contract, courts generally look to ordinary contract law, under which an oral construction agreement is usually enforceable, but the point is left to case law rather than the statute.
How Do States Treat Oral and Implied Construction Contracts?
Writing required, 1 state: New Jersey defines contract in N.J.S.A. 2A:44A-2 as an agreement in writing, signed by the party against whom the lien claim is asserted, and for suppliers it includes a signed delivery or order slip. Writing required in some cases, 7 states: Arizona (owner-occupied dwellings), Colorado (owner contracts over $500), Louisiana (equipment lessors), Massachusetts (contractors, subs, and suppliers), Michigan (residential contractors), South Carolina (landscaping over $5,000), and Texas (homesteads). Oral or implied recognized, 20 states: Illinois covers contracts express or implied, or partly expressed or implied (770 ILCS 60/1); Vermont covers a contract whether in writing or not (9 V.S.A. section 1921); Mississippi limits the lien to the amount due under an express or oral contract, subcontract or purchase order. Silent on form, 22 states: New York's Lien Law section 3 asks only whether work was furnished with the consent or at the request of the owner. Colorado's section 38-22-101(3) says owner contracts over $500 shall be in writing, but also keeps a lien for the value when the contract is not filed and never says an unwritten contract defeats the lien. Massachusetts requires a written contract for contractor liens under c. 254 section 2 and for subcontractors, suppliers, and equipment lessors under section 4; only the section 1 personal-labor lien escapes it.
Which States Require a Written Contract for a Mechanics Lien?
Writing required: New Jersey (N.J.S.A. 2A:44A-2, 2A:44A-9). Writing required in some cases: Arizona (A.R.S. section 33-1002, only a person with a written contract directly with an owner-occupant may lien that dwelling); Colorado (C.R.S. section 38-22-101); Louisiana (La. R.S. 9:4802, lessors need a written lease; 9:4811, a general contractor on work over $100,000 needs a timely filed notice of contract); Massachusetts (M.G.L. c. 254 sections 1, 2, 4); Michigan (MCL 570.1114, residential contract and every amendment in writing); South Carolina (S.C. Code section 29-5-26); Texas (Prop. Code section 53.254, homestead contract written, executed before work, signed by both spouses, filed with the county clerk). Oral or implied recognized: Alaska (AS 34.35.120), Delaware (25 Del. C. section 2702), Florida (section 713.01(6), written or unwritten, express or implied), Georgia (O.C.G.A. section 44-14-361), Hawaii (HRS section 507-42), Illinois (770 ILCS 60/1), Maryland (Real Prop. section 9-101(c)), Minnesota (section 514.011), Mississippi (section 85-7-403), Montana (MCA section 71-3-522), Nebraska (section 52-127), Nevada (NRS 108.222), North Carolina (N.C.G.S. section 44A-8), Ohio (R.C. section 1311.02), Oklahoma (42 O.S. section 141, oral or written contract), Pennsylvania (49 P.S. section 1201), Rhode Island (section 34-28-1, oral or written contract or request), Tennessee (section 66-11-101), Vermont (9 V.S.A. section 1921), Wisconsin (section 779.01). Silent on form: Alabama, Arkansas, California, Connecticut, Idaho, Indiana, Iowa, Kansas, Kentucky, Maine, Missouri, New Hampshire, New Mexico, New York, North Dakota, Oregon, South Dakota, Utah, Virginia, Washington, West Virginia, and Wyoming. Arkansas, Georgia, Mississippi, and Tennessee were read from an unofficial compilation.
What Are the Deadlines and Notices When There Is No Written Contract?
The filing deadline does not change because the contract was oral, but the paperwork a written contract would have carried does. Minnesota section 514.011 requires the pre-lien notice in any written contract with the owner and, if there is none, separately within ten days after the work is agreed upon. Wisconsin section 779.02(2)(a) requires a prime contractor with no written contract to serve its notice within 10 days after first furnishing, or lose its own lien unless it pays all its subs. Rhode Island section 34-28-4.1 requires a direct contractor other than a supplier to give the Notice of Possible Mechanic's Lien before starting, in a written contract or by certified mail. Missouri section 429.012 makes the original contractor's lien notice a condition precedent, deliverable as late as the first invoice. Florida's section 713.015 residential disclosure, for an oral contract, goes in a document referencing the contract, and Illinois's owner-occupied notice may be a separate printed statement. Texas's homestead contract must be executed before any material is furnished or labor performed, so it cannot be papered after the fact.
How Much Can You Lien for Without an Agreed Price?
Alaska, Montana, and Nebraska define the contract price as the reasonable value of the services or materials when no price is agreed, and Tennessee includes overhead and profit in reasonable value. Minnesota gives the agreed sum or, in all other cases, the reasonable value of the work done. Washington uses the customary and reasonable charge, Nevada fair market value plus a reasonable allowance for overhead and profit, Florida the value of the labor, services, or materials, and Hawaii the fair and reasonable value. New Jersey caps the lien at the unpaid contract price and Michigan at the contract amount less payments, with no fallback. California makes every lien the lesser of reasonable value or the agreed price. Reasonable value is a fact question the claimant carries, proved with prior invoices, rate sheets, time records, and material receipts.
Who Needs to Worry About Liens on Unwritten Contracts?
Subcontractors starting on a phone call, suppliers shipping against unsigned purchase orders, residential contractors pricing jobs at the kitchen table, and every trade doing extras on verbal direction. The real exposure is narrower: residential contractors dealing directly with homeowners in Texas, Michigan, and Arizona, plus home improvement writing rules in states such as Connecticut, Hawaii, California, New York, and Maine; trade contractors and suppliers in Massachusetts; everyone in New Jersey; and equipment lessors in Louisiana. Sub-tier claimants on owner-occupied homes face separate limits no writing fixes: Tennessee gives only the prime contractor a lien on residential contracts, Pennsylvania bars a sub's lien when the owner paid the full contract price, and Utah shields an owner who signed a written contract with a licensed contractor and paid in full.
What Happens If a State Requires a Writing and You Don't Have One?
The lien fails and the debt survives. The contract claim against the customer remains, and in most states an oral construction contract is enforceable as a contract even where the lien statute will not secure it. Recording a lien known to be unsupported invites a discharge action and, in many states, a fee award to the owner; the better path is the contract claim, any payment bond, and in some states a trust-fund claim. Connecticut's section 20-429 makes an unwritten home improvement contract unenforceable against the owner, and Hawaii's chain from section 444-25.5 to section 480-12 can make a noncompliant home improvement contract void; their effect on a lien is a case-law question.
The 5 Most Common Mistakes on Handshake-Deal Liens
(1) Assuming no contract means no lien: in 42 states the statute recognizes oral contracts or is silent on form. (2) Starting a homestead or owner-occupied job before the paper is signed: Texas requires the homestead contract before work, signed by both spouses and filed; Arizona requires a written contract directly with the owner-occupant. (3) Doing verbal extras on residential work in Michigan, where amendments must be in writing, or in Massachusetts. (4) Forgetting the notice the contract would have carried: Minnesota and Wisconsin give 10 days, Rhode Island requires certified mail before work, and Missouri's original-contractor notice is a condition precedent. (5) Liening a price you cannot prove: a disputed oral price becomes a reasonable-value fight, and California caps every lien at reasonable value.
Frequently Asked Questions
Can you file a mechanics lien without a written contract?
In most states, yes. Of the 50 state lien statutes checked for this guide, only New Jersey requires a signed writing from every claimant. Seven more require a writing for certain claimants or projects: Arizona, Colorado, Louisiana, Massachusetts, Michigan, South Carolina, and Texas. Twenty statutes expressly recognize oral, unwritten, or implied contracts, including Florida, Illinois, Ohio, Oklahoma, Pennsylvania, and Tennessee. The remaining 22 require only a contract, request, or consent without saying what form it takes. A handshake deal is usually lienable; the harder problem is proving the terms.
Which state requires a written contract for every mechanics lien?
New Jersey. The Construction Lien Law defines contract in N.J.S.A. 2A:44A-2 as an agreement in writing, signed by the party against whom the lien claim is asserted. For a supplier, a delivery or order slip signed by that party counts as the contract. New Jersey also measures the lien by the unpaid portion of the claimant's contract price under section 2A:44A-9, with no reasonable-value fallback, so a claimant with nothing signed has nothing to lien.
Do you need a written contract to lien a homestead in Texas?
Yes. Under Tex. Prop. Code section 53.254, a lien on a homestead requires a written contract between the person furnishing the work or materials and the owner, executed before any material is furnished or labor performed, signed by both spouses if the owner is married, and filed with the county clerk of the county where the homestead is located. Outside homesteads, Chapter 53 sets no contract-form requirement. Failing to give the separate residential disclosure statement under section 53.255 does not by itself invalidate a lien.
How much can you lien for if there was no agreed price?
Usually the reasonable value of the work, if the statute addresses it at all. Alaska, Montana, Nebraska, and Tennessee define the contract price as reasonable value when no price was agreed. Washington uses the customary and reasonable charge, Florida the value of the labor, services, or materials, and Minnesota the reasonable value of the work done. Nevada allows fair market value plus a reasonable allowance for overhead and profit. California caps every lien at the lesser of reasonable value or the agreed price. New Jersey has no fallback at all.
What happens to the preliminary notice if there is no written contract?
In several states the notice that would have been printed in the contract must go out separately, on a short clock. Minnesota section 514.011 requires a contractor with no written contract to deliver the pre-lien notice separately within 10 days after the work is agreed upon. Wisconsin section 779.02 requires a prime contractor with no written contract to serve its notice within 10 days after first furnishing. Rhode Island section 34-28-4.1 requires a direct contractor to send its notice by certified mail before starting if it is not in a written contract.
Can a verbal change order be included in a mechanics lien?
Often, but not everywhere. Florida and Tennessee define contract to include unwritten agreements, and Tennessee expressly includes extras. Michigan is the clearest exception: under MCL 570.1114 a contractor has no lien on a residential structure unless the contract and any amendments or additions to it are in writing. Massachusetts requires a written contract for contractor, subcontractor, and supplier liens under M.G.L. c. 254 sections 2 and 4, which makes unwritten extras a risk there as well. Confirm extras in writing even where the statute does not require it.
What proof do you need for a mechanics lien based on an oral contract?
Proof of who asked for the work, what was furnished, when, and at what price. Text messages and emails approving the scope or price, signed delivery tickets, daily logs, photos, invoices the customer paid without objection, and partial payments all help establish the agreement. New Jersey treats a signed delivery or order slip as a supplier's contract. Delaware requires a claim whose amount is not fixed by a contract to attach a bill of particulars under 25 Del. C. section 2712. Assemble this file before recording, not after the owner disputes the lien.
