Establishes rules to govern contracts between contractors, subcontractors, and other parties to construction contracts

This bill establishes new rules for construction contracts in Missouri involving owners, contractors, and subcontractors on private projects. It defines specific terms like "construction contract" and "work" to include various services and materials used in building or maintaining properties. The legislation prohibits contract clauses that allow parties to withhold payments beyond disputed amounts, prevents contractors from stopping work due to non-payment, and bans agreements requiring work to continue without payment. Additionally, the law declares any contract terms attempting to waive these rights as unenforceable and against public policy.
