Yes. Missouri requires use of statutory lien waiver forms under Missouri Revised Statutes § 429.005. Using a non-compliant form may void the waiver entirely.
A conditional waiver only takes effect when payment is actually received and cleared. An unconditional waiver releases lien rights immediately upon signing, regardless of whether payment is received. Always use conditional waivers when exchanging with a check.
No. Missouri does not require notarization of lien waivers. A signature and date are sufficient.
