Common Supplier Mistakes in Missouri
Missing the Disclosure Notice
Many suppliers fail to send the required preliminary notice early in the project, invalidating their future lien rights.
Filing the lien after 6 months
Waiting too long to file. The deadline is strict and often does not extend for weekends or holidays.
Missing the 6-month enforcement deadline
Filing a lien is not enough; you must enforce it (file a lawsuit) before the enforcement period expires.
