Ohio Rev. Code § 3705.124
An adopted person whose birth occurred in this state, whose adoption was decreed before January 1, 1964, who did not have a new or reissued birth record in the person's adopted name prepared pursuant to division (C) or (D) of section 3705.12 of the Revised Code as those divisions existed before March 19, 1985, and whose adoption is in full force and effect, may apply to the department of health at any time for the preparation of a new birth record in the person's adopted name. On receipt of such an application, the department shall prepare a new birth record in the person's name, in accordance with, and in the form described in, section 3705.12 of the Revised Code. On preparation of the new birth record, the original birth record of the applicant or the birth record issued in the adopted name of the applicant before January 1, 1964, that is being replaced, whichever is applicable, shall cease to be a public record. The department shall maintain the birth record that ceased to be a public record and papers and documents that pertain to it or to the adoption of the applicant in an adoption file. The contents of the adoption file are not a public record and shall be made available only in accordance with section 3705.126 of the Revised Code.
The department promptly shall forward a copy of a new birth record in an applicant's adopted name that is prepared under this section to the local registrar of vital statistics of the district in which the applicant's birth occurred. The local registrar shall file the copy along with, and in the same manner as, the other copies of birth records in the registrar's possession. All copies of the applicant's original birth record or the birth record issued in the applicant's adopted name before January 1, 1964, that is being replaced, and all other papers, documents, and index references pertaining to it that are in the possession of the local registrar or a probate court shall be destroyed, except that the probate court shall retain permanently in the file of adoption proceedings information that is necessary to enable the court to identify both the applicant's original birth record or birth record issued in the applicant's adopted name before January 1, 1964, that is being replaced, and the new birth record in the applicant's adopted name that is prepared pursuant to this section.
