Ohio Rev. Code § 1709.07
Subject to the limitations of section 5731.39 of the Revised Code, on the death of a sole owner or the last to die of all multiple owners, ownership of a security registered in beneficiary form shall pass to the beneficiary or beneficiaries who survived all owners. On proof of death of all owners and compliance with any applicable requirements of the registering entity, but subject to the limitations of section 5731.39 of the Revised Code, a security registered in beneficiary form may be reregistered in the name of the beneficiary or beneficiaries who survived the death of all owners. Until division of the security after the death of all owners, multiple beneficiaries surviving the death of all owners hold their interests as tenants in common. If no beneficiary survives the death of all owners, the security shall be included in the estate of the deceased sole owner of it or the estate of the last to die of all multiple owners of it.
