Non-collusion affidavit

A non-collusion affidavit is a sworn statement in a bid that the bidder set its price independently and didn't agree with competitors to rig the bid.

Many county bid packages include a non-collusion affidavit, sometimes notarized. It certifies that you didn't share prices, agree not to bid, or arrange who would win.

Why it matters

Bid rigging is a crime under federal and state antitrust law. The affidavit makes the certification explicit, and a false statement can lead to disqualification, debarment and prosecution.

Practical points

  • Sign it exactly as the bid form instructs; if notarization is required, an unnotarized affidavit can make the bid non-responsive.
  • Indiana's state public works bid forms include this kind of certification together with the bidder's financial statement.
