Missouri Construction Attorney — Find a Lien & Payment Lawyer (2026)
When Missouri Contractors Need a Construction Attorney
Missouri contractors should consult a construction attorney when (1) a payment dispute exceeds $15,000–$20,000, (2) the original contractor's § 429.012 notice to owner was missed — a condition precedent that defeats the lien entirely — or a subcontractor's § 429.100 10-day notice of intent was missed or sent too late, (3) a claimant missed or is at risk of missing the § 429.080 six-month lien-filing window (60 days for equipment lessors), (4) the § 429.170 six-month foreclosure deadline — measured from filing — is approaching, (5) an owner-occupied residential project lacks the § 429.013 consent of owner, (6) the relation-back priority date (commencement of the work) is contested against a construction mortgage, (7) the owner already paid the general contractor in full and a double-payment fight looms, (8) a lien is alleged to be overstated or filed in the wrong office (the recorder of deeds instead of the circuit court clerk), (9) the project is Missouri public works requiring a payment-bond claim under § 107.170 / § 522.300, (10) the project is federal (Fort Leonard Wood, Whiteman AFB, NGA West, a Corps of Engineers lock and dam, a VA Medical Center), or (11) the contract contains an arbitration clause or a Missouri prompt-payment claim under § 431.180 or § 34.057 is available.
What Missouri Construction Attorneys Do
Missouri construction attorneys handle the full Chapter 429 workflow plus public-works and federal Miller Act work. Services include confirming and, where missed, assessing the consequences of the § 429.012 original contractor notice to owner and the § 429.100 10-day notice of intent; confirming the § 429.013 consent of owner on owner-occupied residential property; preparing and filing the § 429.080 lien statement with the clerk of the circuit court within six months of last work (60 days for equipment lessors); establishing and litigating Missouri's relation-back priority date against construction mortgages; filing § 429.170 lien-foreclosure actions in the correct circuit court within the six-month enforcement window and recording the lis pendens; analyzing Missouri double-payment exposure and advising on lien-waiver discipline; pursuing Missouri prompt-payment claims (private § 431.180 with 18% interest; public § 34.057); filing Missouri § 107.170 (claims under § 522.300) and federal Miller Act bond claims; analyzing contractor-credential compliance (local licensing — no statewide GC license); and enforcing or resisting construction arbitration clauses.
How to Find a Vetted Missouri Construction Attorney
Three reliable paths: (1) The Missouri Bar — lawyer-referral resources and a Construction Law Committee producing CLE on Chapter 429, the § 429.012 notice to owner, the § 429.100 notice of intent, the § 429.013 residential consent, the § 429.080 circuit-court filing, the § 429.170 foreclosure, the relation-back priority rule, the Missouri prompt-payment statutes, and public-works practice under § 107.170; (2) metropolitan bar associations, including the Bar Association of Metropolitan St. Louis and the Kansas City Metropolitan Bar Association, for local circuit-court clerk and foreclosure knowledge; and (3) the Mechanics Lien Management Missouri attorney network filtered by county, claim size, project type (Kansas City and St. Louis metro commercial development, Springfield and Columbia regional construction, Lake of the Ozarks resort work, and Fort Leonard Wood / Whiteman / NGA / Corps of Engineers / VA federal Miller Act), and matter type.
Missouri Construction Attorney Fees
Hourly rates run $275–$500 in the Kansas City and St. Louis metros (Jackson, St. Louis County, City of St. Louis, St. Charles, Clay, Platte) and $225–$400 in greater Missouri (Greene/Springfield, Boone/Columbia, Cole/Jefferson City, Buchanan/St. Joseph, Cape Girardeau). Senior partners at established Missouri construction-focused firms run $450–$675. Flat fees: § 429.012 / § 429.100 notice preparation $150–$400; § 429.080 lien statement + circuit-court-clerk filing $600–$1,800; § 429.170 foreclosure + lis pendens $4,500–$13,000 (through initial pleading); relation-back priority analysis $2,000–$6,000; Missouri § 107.170 / federal Miller Act bond claim $3,000–$12,000; contingency 30%–40% on liquid collection cases, frequently paired with a Missouri prompt-payment fee claim (18% per annum under § 431.180). Initial consultations are typically free or low-cost.
Missouri-Specific Construction Law Issues
Three distinctive features shape Missouri's framework: (1) the original contractor's § 429.012 notice to owner — a written disclosure in ten-point bold type, delivered before the contractor receives any payment, whose compliance is a condition precedent to the creation, existence, or validity of any mechanics lien; a GC that skips it has no lien, and skipping it with intent to defraud is a class B misdemeanor; (2) the circuit-court filing — Missouri files liens with the clerk of the circuit court, not the recorder of deeds, a trap that voids filings lodged in the wrong office; and (3) the compressed six-month windows — the § 429.080 lien statement must be filed within six months of last work, and under § 429.170 the foreclosure must be commenced within six months after filing, with a 60-day window for equipment lessors. Lower-tier claimants also face the § 429.100 10-day notice of intent and, on owner-occupied residential property of four units or fewer, the § 429.013 consent of owner. Missouri liens relate back to and take priority from the commencement of the work, share equal priority, and prime later encumbrances. On public works, no lien attaches — pursue the § 107.170 payment bond (claims under § 522.300); the federal Miller Act (40 U.S.C. § 3131 et seq.) governs Missouri's military, NGA, Corps of Engineers, and VA projects. Missouri has no statewide general-contractor license — licensing is local — and prompt-payment remedies appear at § 431.180 (private, 18% interest) and § 34.057 (public).

What is unique about Missouri construction lien law?
Three features: (1) the original contractor's § 429.012 notice to owner — a written disclosure in ten-point bold type, delivered before the contractor receives any payment, whose compliance is a condition precedent to the creation, existence, or validity of any mechanics lien; a GC that skips it has no lien, and skipping it with intent to defraud is a class B misdemeanor; (2) the circuit-court filing — Missouri files liens with the clerk of the circuit court, not the recorder of deeds, a trap that voids filings lodged in the wrong office; and (3) the compressed six-month windows — the § 429.080 lien statement must be filed within six months of last work, and under § 429.170 the foreclosure must be commenced within six months after filing, with a 60-day window for equipment lessors. Lower-tier claimants also face the § 429.100 10-day notice of intent and, on owner-occupied residential property of four units or fewer, the § 429.013 consent of owner. Missouri liens relate back to commencement of the work, share equal priority, and prime later encumbrances. Missouri has 114 counties plus the City of St. Louis.
How do I find a vetted Missouri construction attorney?
Three paths: The Missouri Bar (lawyer-referral resources and a Construction Law Committee producing CLE on Chapter 429, the § 429.012 notice to owner, the § 429.100 notice of intent, the § 429.013 residential consent, the § 429.080 circuit-court filing, the § 429.170 foreclosure, the relation-back priority rule, the Missouri prompt-payment statutes, and public-works practice); metropolitan bar associations (including the Bar Association of Metropolitan St. Louis and the Kansas City Metropolitan Bar Association); and the Mechanics Lien Management Missouri attorney network filtered by county, claim size, project type (Kansas City and St. Louis metro commercial, Springfield and Columbia regional, Lake of the Ozarks resort, Fort Leonard Wood / Whiteman / NGA / Corps of Engineers / VA federal Miller Act), and matter type. Ask about § 429.012 condition-precedent disputes, relation-back priority fights, and § 429.170 foreclosures.
Can a Missouri construction attorney work on contingency?
Yes, when (1) the debt is liquid and well-documented, (2) the original contractor's § 429.012 notice to owner was given before payment (or the subcontractor's § 429.100 10-day notice of intent was given), (3) any § 429.013 consent of owner exists on owner-occupied residential work, (4) the § 429.080 lien statement was filed with the correct circuit court clerk within six months of last work, (5) the § 429.170 six-month foreclosure window (from filing) is open, (6) the relation-back priority places the lien ahead of or near the construction mortgage, (7) the property has sufficient equity, and (8) a Missouri prompt-payment claim under § 431.180 (18% per annum) or § 34.057 can be added. Contingency 30%–40% of recovery. Because the § 429.012 notice is a condition precedent that can eliminate the lien entirely, pre-engagement diligence on the notice timing, the § 429.080 filing date and office, and the priority date is essential before agreeing to contingency.
Do I need a Missouri construction attorney to file a lien?
Not always, but strongly recommended when a notice requirement is uncertain, the lien is large, the relation-back priority is contested, or public-works or federal bond rights overlap. Missouri traps: skipping the original contractor's § 429.012 notice to owner (a condition precedent that defeats the lien); filing before the § 429.100 10-day notice of intent period runs, or skipping it; ignoring the § 429.013 consent of owner on owner-occupied residential work; filing the § 429.080 lien statement with the recorder of deeds instead of the clerk of the circuit court; miscounting the six-month filing window from when payment became due rather than from last work, or missing the 60-day equipment-lessor window; letting the § 429.170 six-month foreclosure deadline lapse; and recording a void lien against public property instead of pursuing the § 107.170 bond or the federal Miller Act. The Mechanics Lien Management Missouri generator handles routine private filings; condition-precedent disputes, priority fights, and bond claims require attorney representation.
What construction-law resources does The Missouri Bar offer?
The Missouri Bar offers lawyer-referral resources and a Construction Law Committee that produces CLE and practice materials addressing Chapter 429 — particularly the § 429.012 notice to owner (condition precedent), the § 429.100 10-day notice of intent, the § 429.013 consent of owner on owner-occupied residential property, the § 429.080 six-month circuit-court filing, the § 429.170 six-month foreclosure deadline, the relation-back-to-commencement priority rule, the Missouri prompt-payment statutes (private § 431.180 with 18% interest; public § 34.057), public-works practice under the § 107.170 payment bond (claims under § 522.300), federal Miller Act practice, and Missouri construction arbitration. Metropolitan bar associations (including the Bar Association of Metropolitan St. Louis and the Kansas City Metropolitan Bar Association) provide additional content and referrals.
