The Miller Act protects the right to payment for certain construction entities who contribute to federal construction projects. Through the Miller Act, subcontractors and materials suppliers who deal directly with the prime contractor or with the first-tier subcontractor and are unpaid for work performed and materials supplied have the right to sue the party with whom they contracted as well as the bond company providing the Miller Act payment bond. In order to benefit from the Miller Act, the work performed or materials supplied must relate to the initially contracted project, not later repair or warranty work. Important notice and lawsuit deadlines must be met in order to make a successful Miller Act bond claim.
