Title 40 › SUBTITLE II — PUBLIC BUILDINGS AND WORKS › PART A — GENERAL › CHAPTER 31 — GENERAL › SUBCHAPTER III — BONDS › § 3133
If you supplied labor or materials for a government contract and you haven’t been paid or are being sued on the bond, the agency head must give you a certified copy of the payment bond and the contract if you file an affidavit saying so. That certified copy will be treated as proof of what the original says and you must pay any fees the agency sets to make the copy. If you aren’t paid in full within 90 days after your last work or delivery, you can sue on the payment bond for what you’re owed and pursue the case to judgment. If you dealt only with a subcontractor and not the prime contractor, you can still sue if you give written notice to the contractor within 90 days that states the amount and who you supplied. The notice must be delivered with written, third-party proof of delivery or in the way a U.S. marshal serves summons. The suit must be filed in the name of the United States for your use in the U.S. District Court where the work was to be done, and must be started within one year after your last work or delivery. The federal government won’t pay your lawsuit costs. Waiving your right to sue is invalid unless it is written, signed by you, and signed after you provided the labor or materials.
