Ohio Rev. Code § 319.42: Apportionment of unpaid special assessments.

Whenever a portion of a tract or parcel of real estate is conveyed to another owner, and such tract or parcel bears unpaid special assessments, the authority certifying such assessments shall, on request of the county auditor, furnish the auditor with the proportionate amounts of the assessments to be allocated to the portion of the original tract or parcel so conveyed to another owner, and the lien of the assessments, as levied against the original tract or parcel, shall extend to the portion conveyed only to the extent of the amount so allocated to the portion by the certifying authority. This section does not change the total amount of the assessments as originally levied, or the total amount of the balances due.
