Ohio Rev. Code § 727.32: Court to determine amount of recovery.

If in any action for the recovery of a special assessment, it appears that by reason of any technical irregularity or defect, whether in the proceedings of the legislative authority or of any officer of the municipal corporation, or in the plans or estimates, the assessment has not been properly made upon any lot or parcel of land sought to be charged, the court may nevertheless, on satisfactory proof that expense has been incurred which is a proper charge against such lot or parcel of land in question, render judgment for the amount properly charged against it. The court shall make such order for the payment of the costs as is equitable and proper.
