Step 1 — Determine Whether Notice Is Required
Confirm whether the project is owner-occupied residentialand whether you are a subcontractor or supplier. If so, verify that the Notice of Intent to File a Lien was properly served at least 10 days before filing.

Step 2 — Prepare the Missouri Mechanics Lien Statement
Missouri construction lien must include the following information:
Legal property description
Property owner’s name
Claimant’s name and address
Hiring party
Description of labor or materials
Amount claimed
Date work was last furnished
The lien must be verified and notarized.
Step 3 — File the Lien with the Circuit Clerk
Missouri mechanics liens are filed with the Circuit Clerk of the county where the property is located. Filing in the wrong county can invalidate the lien.
Step 4 — Serve the Recorded Lien
After filing a Missouri mechanics lien, a copy of the lien should be served on the property owner within a reasonable time. Missouri law does not impose a strict service deadline, but service should be completed promptly—typically immediately or within a few days of filing—to avoid challenges to enforceability. Service is commonly made by certified mail or personal service, and proof of service should be retained.
Step 5 — Enforce the Lien (If Still Unpaid)
To enforce the lien, the claimant must file a foreclosure lawsuit within six (6) months of filing the lien. Enforcement requires court action.
