Ohio Rev. Code Ann. § 3101.14

Every marriage license shall have printed upon it in prominent type the notice that, unless the person solemnizing the marriage returns a certificate of the solemnized marriage to the probate court that issued the marriage license within thirty days after performing the ceremony, or, if the person solemnizing the marriage is a probate judge who is acting in accordance with section 2101.27 of the Revised Code and who issued the marriage license to the husband and wife, unless that probate judge files a certificate of the solemnized marriage in the probate judge's office within thirty days after the solemnization, the person or probate judge is guilty of a minor misdemeanor and, upon conviction, may be punished by a fine of fifty dollars. An envelope suitable for returning the certificate of marriage, and addressed to the proper probate court, shall be given with each license, except that this requirement does not apply if a marriage is to be solemnized by a probate judge who is acting in accordance with section 2101.27 of the Revised Code and who issued the marriage license to the husband and wife.
