Kan. Stat. § 60-1110
The contractor or owner may execute a bond to the state of Kansas for the use of all persons in whose favor liens might accrue by virtue of this act, conditioned for the payment of all claims which might be the basis of liens in a sum not less than the contract price, or to any person claiming a lien which is disputed by the owner or contractor, conditioned for the payment of such claim in the amount thereof. Any such bond shall have good and sufficient sureties, be approved by a judge of the district court and filed with the clerk of the district court. When bond is approved and filed, no lien for the labor, equipment, material or supplies under contract, or claim described or referred to in the bond shall attach under this act, and if when such bond is filed liens have already been filed, such liens are discharged. Suit may be brought on such bond by any person interested but no such suit shall name as defendant any person who is neither a principal or surety on such bond, nor contractually liable for the payment of the claim.
