This Missouri lien deadline calculator is for original contractors, subcontractors, suppliers, laborers and equipment rental companies. Enter your role, the type of project and your last day of work or delivery, and it shows each deadline under RSMo chapter 429 with the statute section next to it.
Original contractors also tell us whether they gave the owner the statutory Notice to Owner before the first payment. Subs and suppliers on a repair, remodel or addition to an owner-occupied home tell us whether the owner signed a Consent of Owner, because without it there's no lien. If you already filed the lien, add that date and we'll show when the suit to enforce is due.
It takes about 20 seconds, and it's free. When you're ready to file, LevelSet Collections has your 10-day notice of intent served on the owner and files the verified lien statement with the right circuit clerk, in every Missouri county and the City of St. Louis. Liens are $199 to $500 all-inclusive.
Leave blank if you haven't filed yet. With it, we show the enforcement dates too.
Public project? You can't lien public property, but you can still get paid. Ask us how. We get contractors, subs and suppliers paid on public work across the country through Freedom of Information Act and state public-records requests for the contract and payment bond, and Miller Act and state Little Miller Act bond claims. Call or text (469) 694-8003.
