Good News for Missouri Contractors

Missouri does not require a pre-lien preliminary notice for general contractors. Subcontractors and material suppliers may benefit from serving a notice to owner. You still must file the lien within the deadline and in the correct recording office.

Commercial vs Residential

Does the Property Type Change Your Deadline?

Same 6-month deadline. Residential owner-occupied projects may have additional notice requirements — verify with an attorney.

Common Mistakes

What Contractors Get Wrong in Missouri
