A. If at the expiration of the forty-five days any filed and recorded claims are unpaid, the public entity shall file a petition in the proper court of the parish where the work was done, citing all claimants and the contractor, subcontractor, and surety on the bond and asserting whatever claims it has against any of them, and shall require the claimants to assert their claims. If the governing authority fails to file the proceeding any claimant may do so.
B. All the claims shall be tried in concursus and the claims of the claimants shall be paid in preference to the claims of the public entity.
