Bybidder Law and Legal Definition

A bybidder is a person who is employed by a seller or his agent to bid on a property with no purpose to become a purchaser, so that the bidding thereon may be stimulated in others who are bidding in good faith, while he is safe from risk because of a secret understanding that he shall not be bound by his bids. [Osborn v. Apperson Lodge, F. & A. M., 213 Ky. 533 (Ky. 1926)].
