A mechanics’ and materialmen’s lien is a powerful collection tool for contractors, subcontractors, and material suppliers on an Arkansas construction project, and one of the easiest to lose. It lets a party who furnished labor or materials used to improve real property secure payment against the property itself. But the remedy runs on a sequence of notices and deadlines fixed by Arkansas law, and courts enforce that sequence strictly.
For that reason, the advice of a qualified attorney is encouraged for those seeking to pursue a lien claim. However, for those who want to pursue construction liens on their own, or who are interested in the process generally, what follows is a high-level overview of how the process works and where the traps are, with a pointer to a more detailed guide for those who want more information on how to work through a lien claim. For those who would rather go straight to the detail, that guide and its two companion tools are here: the Field Guide, the Jobsite Playbook, and the Lien Clock deadline calculator.
What is a mechanics’ and materialmen’s lien?
Under Arkansas law, a mechanics’ and materialmen’s lien is a statutory claim against real property in favor of those who improve it. When a contractor, subcontractor, supplier, laborer, or design professional is not paid for labor, services, materials, or fixtures used to improve the property, the claim can attach to the improvement and the land beneath it and be enforced by a sale of the property. Ark. Code Ann. § 18-44-101 et seq. The lien can reach the property even where the owner has already paid the general contractor in full, and that reach is what gives it leverage and why owners generally take it seriously.
Who can claim a lien?
The statute reaches a broad set of project participants. Contractors and subcontractors, material suppliers, and laborers may claim a lien for the value of what they furnished, as may a list of design and related professionals: architects, engineers, surveyors, appraisers, landscapers, abstractors, and title insurance agents. The right belongs to the party who improved the property and was not paid, so a supplier several tiers below the owner can hold lien rights even without a direct contract with the owner.
Why is the process so demanding?
Arkansas follows a strict-compliance rule for construction liens. The state’s appellate courts have held that the lien statutes must be followed strictly, and that substantial compliance is generally not enough. A notice served late or sent to the wrong party, or a lien that identifies the property by street address instead of a correct legal description, can be enough to defeat an otherwise valid claim. Because the lien is a creature of statute, its deadlines operate as conditions of the right itself, not as flexible guidelines: miss one, and the lien is generally gone.
Losing the lien is not always the same as losing the debt. A residential contractor who misses the required pre-work notice, for example, loses the lien but generally keeps a claim for the unpaid contract balance. Still, the lien is the leverage, and it is the first thing the statute takes away. That is the single most important thing to understand before pursuing a lien.
What are the deadlines?
Most of the work of a lien claim is meeting a series of deadlines in the right order. At a high level:
- Pre-work notice (residential). On residential projects (four units or fewer), the contractor generally must give the owner a statutory notice before work begins. “Residential contractor” is read broadly. Arkansas appellate courts have applied the requirement to trades that do not think of themselves as home-builders, so a party contracting directly with a homeowner should assume the notice applies to it.
- 75-day notice (commercial). On commercial property, meaning any nonresidential real estate or residential property with five or more units, a subcontractor, service provider, supplier, or laborer must serve a notice on both the owner and the contractor within 75 days of its last labor or materials.
- 10-day notice (all projects). Before filing, a claimant must give the owner at least 10 days’ notice of the claim, stating the amount due and from whom it is due. This one applies on every project, residential and commercial alike.
- File the lien (120 days). The verified lien must be filed with the circuit clerk within 120 days of the last labor or materials, or for a contractor, substantial completion. It must carry a correct legal description of the property; a street address will not do.
- Foreclose (15 months). To enforce the lien, the claimant must file suit and a lis pendens within 15 months of recording the lien, or the lien becomes void by operation of law.
- Release of lien (10 days after payment). Once the amounts owing are paid, the claimant must release the lien of record, and Arkansas law gives it ten days to do so. A claimant who neglects that for ten days after payment is liable to anyone injured by the delay.
Each step carries its own service rules and content requirements, and the intervals are fixed by statute. Ark. Code Ann. §§ 18-44-114 to -119, -131.
What about public projects?
Public works are not lienable in Arkansas, so a claimant on a public job pursues a bond rather than the property. On a public construction contract of more than $50,000, the contractor must furnish a payment bond for the full contract amount and file it with the circuit clerk of the county where the work is performed before construction begins. Those deadlines are shorter than the lien deadlines. Suit on the payment bond must be brought within one year of the earlier of final payment or the contractor’s ceasing work, and a claimant with no contract with the bonded contractor must give that contractor and its surety written notice within ninety days of its last labor or materials before filing suit, as a condition of the suit rather than merely a deadline. Ark. Code Ann. §§ 18-44-503, -506, -507, -508.
What changed recently?
The development most likely to affect a claim filed in the last year concerns priority, meaning where a lien stands relative to a construction lender’s mortgage. Act 479 of 2025 narrowed the traditional relation-back rule and created a safe harbor that lets a lender record an affidavit of non-commencement to establish the priority of its mortgage. Ark. Code Ann. § 18-44-110. The practical takeaway is that priority over a construction lender can no longer be assumed the way it once could, and the mechanics of the safe harbor are technical enough to reward careful attention early on a project.
Working through the process
Because the process is exacting and the cost of a misstep is the loss of the claim, many parties engage a lawyer to prepare and file a lien, or simply to check a deadline before it passes. That is often the prudent course. For those who want to understand the steps first, or who are working through a claim on their own, good practical guidance goes a long way.
To that end, we have published a detailed field guide to the Arkansas lien process, current through the 2026 First Extraordinary Session, with the governing deadlines, the required notice language, and the forms. It comes with two companion tools built to work from on a live project:
- Field Guide: Arkansas Mechanics’ and Materialmen’s Liens, the full practical guide, including the forms.
- Jobsite Playbook: a color-coded quick reference to the notices and deadlines, by role.
- The Lien Clock: a deadline calculator that computes each date from your project dates.
Used together, they lay out the sequence in plain terms, so you can see what is due, when, and in what order, whether you are handling a claim yourself or working with counsel.
