Ohio Revised Code Title XXI. Courts Probate Juvenile § 2107.76

No person who has received or waived the right to receive the notice of the admission of a will to probate required by section 2107.19 of the Revised Code may commence an action permitted by section 2107.71 of the Revised Code to contest the validity of the will more than three months after the filing of the certificate described in division (A)(3) of section 2107.19 of the Revised Code. No other person may commence an action permitted by section 2107.71 of the Revised Code to contest the validity of the will more than three months after the initial filing of a certificate described in division (A)(3) of section 2107.19 of the Revised Code. A person under any legal disability nevertheless may commence an action permitted by section 2107.71 of the Revised Code to contest the validity of the will within three months after the disability is removed, but the rights saved shall not affect the rights of a purchaser, lessee, or encumbrancer for value in good faith and shall not impose any liability upon a fiduciary who has acted in good faith, or upon a person delivering or transferring property to any other person under authority of a will, whether or not the purchaser, lessee, encumbrancer, fiduciary, or other person had actual or constructive notice of the legal disability.
