What Is a Mechanics Lien in Kentucky — Complete 2026 Guide
Uniform 6-Month Filing Deadline Under KRS 376.080
Under KRS 376.080, every Kentucky mechanics lien claimant — original contractor, subcontractor, sub-subcontractor, or material supplier — must file a verified statement of lien with the County Clerk of the county where the property is located within 6 months from the date the last item of labor, materials, or supplies was furnished. The 6-month window is uniform across all claimant tiers — Kentucky does not split the filing window between original contractors and subs as Kansas, Oklahoma, and Alabama do. The deadline is absolute. Missing the 6-month filing window permanently eliminates the claimant's lien rights for that project. Each claimant's clock runs from that claimant's own last date of substantive furnishing — not the project completion date and not the prime contractor's last day on site. The verified statement of lien must include the claimant's name and address, the property owner's name, the contracting party's name, a sufficient legal description of the property, the amount claimed, an itemized statement of the labor or materials furnished, and verification by oath. Kentucky courts enforce the verification and property-description requirements strictly.
Dual-Track Pre-Filing Owner Notice Under KRS 376.010(3)
Under KRS 376.010(3), every Kentucky sub-tier claimant — subcontractor, sub-subcontractor, or material supplier without a direct contract with the property owner — must serve a written notice of intent to assert a lien on the property owner before filing the lien statement. Kentucky's notice rule operates on a dual track: 75 days from last furnishing on commercial projects and 120 days from last furnishing on owner-occupied single or double family dwellings, but the 75-day rule still controls if the residential contract price exceeds $1,000. The notice is typically served by registered or certified mail with return receipt requested, addressed to the owner at the owner's last known place of residence. The KRS 376.010(3) pre-filing owner notice is a strict precondition to lien rights for sub-tier claimants. A sub who files the lien statement within the 6-month KRS 376.080 window but failed to serve the KRS 376.010(3) owner notice within the applicable 75-day or 120-day window has no valid lien — Kentucky courts will void the lien on owner notice grounds even when the filing itself is timely. The notice must include the claimant's name and address, a statement of intent to assert a lien, the amount claimed, the property description, and identification of the contracting party. Original contractors do not need to serve the pre-filing owner notice; the contract relationship satisfies the notice purpose.
120 Counties and the County Clerk Filing Convention
Kentucky mechanics liens are filed with the County Clerk of the county where the improved property is located under KRS 376.080. Kentucky has 120 counties — among the most of any state in the United States and tied with Texas behind only Georgia (159 counties) and Texas itself (254 counties). The most active Kentucky construction counties include Jefferson County (Louisville — the largest city and the heart of the Louisville metro, with the highest residential and commercial construction volume in the state), Fayette County (Lexington — home to the University of Kentucky and the second-largest metro), Kenton County (Covington — the northern Kentucky/Cincinnati metro), Boone County (Florence, Burlington — the fastest-growing northern Kentucky county and home to the Cincinnati/Northern Kentucky International Airport), Campbell County (Newport, Bellevue), Warren County (Bowling Green — home to Western Kentucky University and the General Motors Corvette Plant), Hardin County (Elizabethtown — anchored by Fort Knox), Daviess County (Owensboro), Madison County (Richmond, Berea), and McCracken County (Paducah). Each County Clerk's office is located in the respective county courthouse. Kentucky's 120-county filing structure means contractors operating across multiple Kentucky counties must track filing-office specifics for each — fee schedules, document formatting requirements, and electronic-filing capabilities vary by county.
12-Month Enforcement Deadline Under KRS 376.090
Under KRS 376.090, an action to enforce a Kentucky mechanics lien must be commenced in the Circuit Court of the county where the property is located within 12 months from the date the lien statement was filed with the County Clerk. Kentucky's 12-month enforcement window is consistent with the southern and midwestern norm and longer than the 6-month windows in Idaho, Alaska, Colorado, and Mississippi, the 180-day windows in Utah and Wyoming, and the 8-month window in Washington. Despite the comparatively generous window, claimants should not delay enforcement: payment negotiations that drift past the 12-month mark cause the lien to expire by operation of law. Calendar the 12-month enforcement deadline immediately upon filing, set reminders at 6 months, 9 months, and 11 months, and retain Kentucky construction counsel by month 11 if the dispute remains unresolved. Once the 12-month window closes under KRS 376.090, the lien cannot be enforced regardless of merit — only an unsecured contract claim against the responsible party survives.
Frequently Asked Questions
How long do I have to file a mechanics lien in Kentucky?
Kentucky's mechanics lien filing deadline is 6 months from the date the last item of labor, materials, or supplies is furnished, under KRS 376.080. The 6-month window applies uniformly to original contractors, subcontractors, sub-subcontractors, and material suppliers. Sub-tier claimants must additionally serve the KRS 376.010(3) pre-filing owner notice within 75 days (commercial) or 120 days (owner-occupied 1-2 family residential, or 75 days if the residential contract price exceeds $1,000).
Do subcontractors need a preliminary notice in Kentucky?
Yes. Under KRS 376.010(3), Kentucky sub-tier claimants must serve a written notice of intent to assert a lien on the property owner — within 75 days of last furnishing on commercial projects, or within 120 days on owner-occupied single or double family dwellings (75 days if the contract price exceeds $1,000). The pre-filing owner notice is a strict precondition to lien rights — failure to serve it within the applicable window is fatal even if the lien statement itself is filed within the 6-month deadline. Original contractors do not need to serve the notice.

Under KRS 376.010, every contractor, subcontractor, sub-subcontractor, material supplier, equipment lessor, laborer, architect, engineer, landscape architect, and surveyor who furnishes labor, services, materials, or equipment for the improvement of real property in Kentucky has a mechanics lien — provided the 6-month filing deadline under KRS 376.080, the 75-day commercial or 120-day owner-occupied residential pre-filing owner notice under KRS 376.010(3) (if sub-tier), and the 12-month enforcement deadline under KRS 376.090 are all satisfied.
