Ohio Rev. Code § 3953.28
Every title insurance company shall file with the superintendent of insurance, all forms of title policies and other contracts of title insurance before the same are issued. Any such filing may be made by a title insurance rating organization in behalf of all its members or subscribers. In no event shall any title insurance company issue any such form of policy or contract until thirty days after it has been filed with the superintendent unless it has received earlier approval by the superintendent. Unless the superintendent disapproves a form of title policy or contract of title insurance within thirty days from the date of its filing, such filing shall be deemed to have been approved. Forms of title policies and other contracts of insurance, as used in this section, shall be deemed to include binders for insurance and policies of insurance or guaranty, together with all the terms and conditions of insurance coverage or guaranty that relate to title to any interest in real property and which are offered by a title insurance company. They shall, however, specifically exclude: reinsurance contracts or agreements, all specific defects in title that may be ascertained from any examination of the risk and excepted in such binders or policies, together with any affirmative assurance of the title insurance company with respect to such defects whether given by endorsement or otherwise, and such further exceptions from coverage by reason of limitations upon the examination of the risk imposed by an applicant for insurance or through failure of an applicant for insurance to provide the data requisite to a judgment of insurability.
